Recommend a good brand, Hikvision camera brand ranking first, the praise rate is more than 90%! No. 1 in market share! Hikvision’s surveillance cameras have comprehensive functions. This product is designated as the leader of smart homes, and is a network smart product that can watch the captured images at any time through mobile phones. It is understood that the product can not only view the current painting at any time, accurately record the picture, but also play back any recorded clips, and users can conduct real-time intercom through its built-in voice function. The Hikvision surveillance camera can be directly connected to the router. As long as the IP address of the Hikvision surveillance camera and the router are in the same network segment, real-time monitoring can be performed. The product is stored in the hard disk of the router and can be stored for users for a quarter. Not too much. In terms of network clarity, Hikvision.

In recent years, small cameras have been used more and more in the family,DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA NVR4208-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,DAHUA DH-NVR4208-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,NVR4208-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,DH-NVR4208-4KS2/L,NVR4116-4KS2/L Price,NVR4116-8P-4KS2/L price,NVR4208-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price,DH-NVR4208-4KS2/L price and their functions have also been upgraded from a single security to a smart device that can remotely take care of the elderly, children, and check the status of pets.
So, which brand of home camera is better? I chose 3 mainstream brand products currently on the market, 360 smart camera PTZ 7P ultra-clear version, Xiaomi Xiaobai smart camera A2, and EZVIZ smart camera AI PTZ version for in-depth comparison evaluation.

【Exterior】
The body of the 360 ​​smart camera PTZ 7P is a white integrated design, the black prototype camera is very eye-catching, and the base is designed with a PTZ, which can be rotated.

The camera of Xiaomi Xiaobai is divided into upper and lower parts, the part is relatively small, and the base is also a gimbal.

The shape of fluorite is relatively unique, it is an overall prototype design, and the silver-gray part below is equivalent to a gimbal.

【Function experience】
The 360 ​​smart camera PTZ 7P ultra-clear version of the APP, by default, has the following functions: review, image quality selection, invite family members, listen to music, intelligent tracking, sleep, screen lock and humanoid logo. By dragging the monitoring screen, you can control the rotation of the PTZ. Intelligent tracking can also be set to automatically follow the recognized human figure.
The smart housekeeping function will synchronize in the mobile APP when someone appears and the screen changes, which is convenient for the owner to omit irrelevant screens and quickly check the changes in the home, such as the happy time of the family in the living room, the cat owner’s dynamics, the situation of visitors, etc.

Speaking of cat owners, I think many friends who play cats also want to see what it is doing when they go to work during the day. At this time, the camera needs to be able to change the angle to find the cat owner who is elusive.
The 360’s patrol function can automatically turn the camera with one button, and inspect the situation in the house in multiple directions.

You can also use the joystick to manually switch the DAHUA NVR4208-8P-4KS2/L detection angle.

Turning on the intelligent tracking function can also allow the camera to automatically switch the camera angle to follow the appearance of people and animals.

The 360 ​​smart camera PTZ 7P ultra-clear version is also equipped with many functions of smart cameras, such as smart housekeeping, face recognition, crying/screaming detection, timed cruise and other functions.

 

In addition to the more conventional smart camera functions, I also discovered a function of the 360 ​​for playing content: listening to music.
We all know that cameras are built-in speakers

Yes, you can talk to people at home through the camera outside through your mobile phone.
However, 360 makes full use of the speakers, and has built-in a lot of sound content in the APP interface, including music, children’s songs stories, and historical humanities audio content.

 

I listened to a hundred forums

Speaking of Wang Yangming, the dahua NVR4216-4KS2/L sound effects and content quality are good, which is a small surprise.

Xiaomi Xiaobai camera can also manually control the angle of the camera, but there is no one-key cruise function of 360.
Xiaomi Xiaobai’s humanoid tracking function is similar to 360’s intelligent tracking. Automatic nursing function, similar to 360’s smart housekeeping.

Start the automatic nursing mode, and you can view the characters, crying, and other sounds separately.

Xiaomi Xiaobai’s smart cruise function, like the 360, can add a set cruise time, the camera will automatically patrol 360 degrees, and the cruise maintenance time can be set through the APP.

Xiaomi Xiaobai also has an album function, which is to package the video scenes of the family together into a collection.

 

The function of the APP is relatively simple.
The gimbal operation is the same as Xiaomi Xiaobai, it only supports manual operation, and there is no timed cruise function.
The expression recognition function needs to be downloaded separately.

However, EZVIZ has a privacy masking function, which can block the camera screen with one click. If the security is in private rooms such as bathrooms and bedrooms, it is still practical.

In addition, in terms of content, EZVIZ APP can watch short videos. But personally, I really don’t think this function is used. Isn’t it fragrant to watch videos and swipe Douyin? Who would deliberately swipe video on the camera?

【Image quality effect】
In the daytime camera images, the picture quality is clear.
The following three screenshots are the daytime camera effects of the 360, Xiaomi Xiaobai and EZVIZ cameras.

 

Take a look at night vision again. The order is still 360, Xiaomi Xiaobai and EZVIZ cameras.

 

It can be seen that the night vision effect of fluorite is relatively blurred, and the clarity of 360 and Xiaomi Xiaobai are still acceptable.
Finally, I summed up a table to see the comparison of the three cameras except the appearance.

DAHUA NVR4116-4KS2/L Price DAHUA NVR4116-8P-4KS2/L price DAHUA NVR4208-4KS2/L price Summarize:
1. If your immediate needs are real-time calls, you must not buy Mijia.
2. If you want to watch the playback, or pay attention to the night vision effect, it is not suitable for fluorite.
3. If you want a more comprehensive camera, 360 is more suitable.
4. If you are interested in the unique appearance and have more needs for privacy shielding, you can choose fluorite.
After comprehensive consideration, I finally chose the 360, because I have a cat at home, and the one-key patrol of the 360 ​​is quite attractive to me. Using the up, down, left, and right keys of the gimbal to find the cat is really labor-intensive. When the office is tired , take a cruise to see my egg tart (the name of my cat), it is still very interesting: this cat sleeps on a tatami mat in summer, and sleeps next to a heater in winter, which is very cold and hot. The third cat litter I bought for it in the living room, and it has finally been used more frequently recently (the first two were disliked).
Of course, as my family went to primary school happily, when I was working overtime, I would also switch angles through the 360 ​​gimbal to see if he was obediently learning English at home or playing games secretly overtime. I don’t know if it has something to do with the deterrent effect of the camera, or if Le Ran grows up and becomes more sensible, I watched this kid on the APP, and now when I get home, I can consciously use the Pomodoro to set an alarm for 20 minutes, and then close the booth after playing the game. I am very happy to learn English.

Generally, when we consider monitoring, there are practical needs, or to protect property, or to take care of family members, etc. Generally speaking, I think the installation can be considered in the following situations:

1. There is no one at home for a long time, for safety and security reasons. For example, there is no one at home during work every day, long time away from home on business trips, frequent long-distance travel and so on.

2. There are elderly people with inconvenience at home, who need to observe the status of the elderly at any time and contact them at any time.

3. There is a baby at home alone or a nanny is needed to take care of it alone.

4. There is a cat owner and a dog owner at home, who wants to lick the dog and suck the cat.

5. Other special areas that you want to observe in real time. Such as balcony, courtyard, own parking space, etc.

In addition, there are five things to keep in mind when installing surveillance cameras at home:

1. Do not install cameras in places involving living privacy, such as bedrooms, bathrooms, and bathrooms. The installation location can choose to be facing key locations such as the entrance door, living room, balcony, etc.

2. The access password of the surveillance camera should be changed frequently. Although this does not eliminate security risks, it will be safer.

3. Keep the surveillance camera firmware updated. Responsible manufacturers will often repair sensitive issues and bugs, and timely upgrades will ensure the security of surveillance cameras.

4. Try to turn it off when adults are at home, or set the timer switch function. The easiest way is to directly physically block it.

5. The installation of surveillance cameras at home requires the unanimous consent of the family to avoid unnecessary family conflicts.

3. What types of home surveillance cameras are there?
1. According to the shape, there are mainly bolts, ball machines, dome machines, PTZ machines, etc.

Bolt: The appearance is rectangular or cylindrical, and the monitoring position is fixed, but the imaging is usually clearer. It can be used for both long-distance monitoring and wide-angle monitoring. It is more suitable for outdoor roads and underground warehouses/warehouses with low illumination. , residential outdoor environment and other places.

Dome camera: It has a spherical appearance and integrates multiple functions such as camera, zoom lens, pan/tilt, decoder, and protective cover.

Hemispherical machine: It is hemispherical in appearance, small in size, beautiful and concealed, and easy to install. It is mostly used in office areas, corridors, elevators and other places with relatively fixed positions.

Pan-tilt machine: a surveillance camera with a pan-tilt, which can rotate the camera in two directions, horizontal and vertical, so as to maximize the monitoring range. Some smart cameras also have automatic tracking functions. At present, most of the home surveillance cameras use a PTZ machine indoors, which is easy to install, can be hoisted or placed at will, and the control is more flexible.

In addition, there are some uncommon types, such as gun balls, gimbal bolts and other deformation combinations, fisheye machines, card machines and other special types, all of which are products for certain specific needs, so I won’t repeat them here.

POE power supply can support longer transmission distance, but because our general household optical modems or routers do not support network cable power supply, it is necessary to configure additional POE switches or POE DVRs that support power over Ethernet, and the cost will be relatively increased.

This method can be considered if there are multiple surveillance cameras in the home or if there are additional requirements for the monitoring distance.

Battery-powered and solar-powered, the advantage is that there is no need to consider wiring problems, and the installation is simple. However, the disadvantages are also obvious, the cost is high, and it cannot support continuous and uninterrupted monitoring for a long time. It is more suitable for field operations or short-term monitoring needs, and this method is generally not considered for home monitoring.
3. According to the network supply method, there are mainly three types: network cable, wireless and flow card.

The network supply method is relatively easy to understand. At present, most mainstream home surveillance cameras support wireless WIFI connection.

Black light night vision is a night vision method that has only appeared in recent years, mainly to solve the problem of image color loss in dark night environments. The dual-sensor architecture is adopted, based on the principle of human eye bionics, to solve the contradiction between the interference of color and brightness, which greatly improves the nighttime imaging effect, and can have an excellent color image visual experience even under extremely low illumination.
Due to the relatively high cost of black light night vision function, home monitoring is generally not considered, and it is usually used in squares, parks, scenic spots, streets, stations, highways and other scenes that require night color monitoring and snapshots.
4. Memory card capacity
From the perspective of cost performance, the current indoor surveillance cameras generally use memory cards to store video recording files.
So how to choose the right memory card size when choosing? Here is a brief introduction to the calculation method of video storage.
The video storage capacity of a surveillance camera is affected by various factors such as video resolution, code stream, frame rate, and compression format. One of the most important parameters is the code stream.
The code stream, also known as the code rate, is a parameter used to represent the amount of video data in a unit time. Under the same resolution and frame rate, the larger the code stream is, the higher the video picture quality is, and the larger the storage space is. On the contrary, the lower the video picture quality is, the smaller the storage space is.
The current mainstream storage capacity calculation formula is:
The storage capacity of video recording for one day (unit: G) = code stream (Mbps) / 8 (conversion of bytes and bits) / 1024 (converted to G) * 3600 seconds (per hour) * 24 hours (per day).
Taking the 2-megapixel H265 compression format as an example, the default code stream is set to 2Mbps, then the storage space required per day in the case of uninterrupted recording is: 2Mbps/8/1024*3600*24 ≈ 21G.
By analogy, the default stream of 3 million pixels is 2.5Mbps, and the daily storage space is: 2.5Mbps/8/1024*3600*24 ≈ 26G. The default stream of 4 million pixels is 3.75Mbps, and the daily storage space is: 3.75Mbps/8/1024*3600*24 ≈ 40G.
It should be noted that different brands of cameras have different video encoding and calculation methods, and the code stream itself can also be adjusted in the camera settings. For example, for a 4-megapixel camera, we can also set the bit rate to 1Mbps, so that the storage space occupied every day is about 10G, which can greatly save the memory card space.
5. Smart function
With the development and popularization of AI, many intelligent AI technologies have also been applied to surveillance cameras, including: humanoid detection, face recognition, motion tracking, crying detection, abnormal sound detection and other functions, making surveillance cameras also have greater applications. space.

The specific applications of various AI functions will be introduced in detail later according to the needs of different scenarios.
6. Other
Other factors that need to be considered are installation method, waterproof, privacy protection, etc. We can choose according to our own situation.
Installation method: Common installation methods include placement, hoisting, brackets, poles, etc.
Waterproof function: Indoor surveillance cameras usually do not require waterproof function. Regarding the waterproof level, I have detailed instructions in “Outdoor”.
Privacy protection: Some cameras have a custom mask function, which can be hidden by controlling the camera through the APP. Friends who are more concerned about security and privacy can pay attention to this function.

6. Recommended cameras for common scenes at home
More often, we choose surveillance cameras for a specific need, such as taking care of the elderly and children, sucking cats, monitoring our own parking spaces, etc., which requires us to pay attention to some targeted functions.
The following are some cost-effective surveillance cameras recommended for common household needs.
1. Take care of the elderly at home
When the elderly in the family are getting older and their children cannot accompany them, they are most worried about the life and health of the elderly, and many elderly people do not know or say they do not like to use electronic products such as mobile phones, so one can be seen and used at any time. Surveillance cameras with voice calls are necessary.
Nowadays, home surveillance cameras are becoming more and more intelligent. For the situation of taking care of the elderly at home, in addition to the basic functions, more consideration can be given to whether the camera supports one-key calling, abnormal sound detection, fall detection and other functions.
The one-key call function allows voice calls to be initiated from the camera, making it easy for the elderly to contact their families at any time;
The abnormal sound detection function can receive an alarm immediately if the elderly fall down or call for help;
The fall detection function is used to identify and give an alarm when someone falls down on the monitoring screen.
Considering these aspects, you can choose 360 ​​smart camera and EZVIZ C6WI flagship smart AI camera.

Update: Recently, many friends have been inquiring about surveillance cameras that accompany pets. One of the interesting points is that they want to track their movements.
Surveillance cameras that can move and track have surpassed the concept of traditional surveillance and entered the field of robots. After searching for a long time, I experienced an Enabot intelligent pet companion robot recommended by enthusiastic friends. I think it is more suitable for taking care of pets at home. Here Also recommend it.
The biggest advantage of this enabot intelligent companion robot is that it is no longer limited to fixed scenes, and can move around the house to achieve monitoring without dead ends.

3. Take care of the baby at home
Taking care of babies is also one of the main reasons for installing cameras in our homes.
Now more and more home cameras support intelligent functions such as baby crying detection and abnormal sound detection, such as the aforementioned nvr4116-8p-4ks2-l, Le Orange TP7, 360 smart camera, Huawei Puque smart camera, etc. The optional range rather broad.
If your baby is in infancy and pays more attention to cry detection, you can choose ipc-eb5541-as, which supports sound source localization, cruise tracking, sound detection is more sensitive, and can automatically rotate and track after abnormal sound is detected, which can better Protect your baby.

360° panoramic view, 360° infinite cruise.
Intelligent listening to voice and position, real-time automatic follow-up.
Two-way voice calls can be shared in real time with family members for simultaneous viewing.

Regarding the choice of surveillance cameras to take care of the baby at home, I wrote an article specially, and made some introductions and recommendations for the characteristics of children of different ages. Friends who have babies at home can refer to:
4. Support zoom and zoom
In most cases, home surveillance cameras are fixed-focus, and with a gimbal, you can observe the indoor situation in all directions.
But sometimes we encounter situations where we need to take care of the overall situation and observe key parts, such as whether the doors and windows are locked, whether there are forgotten items on the desktop, etc. At this time, we can consider surveillance cameras that support optical zoom.
It should be noted that optical zoom is realized by hardware. When the monitoring screen is enlarged, it will not affect the clarity of the screen. A camera can take into account the overall situation and details.
TP-LINK’s binocular ultra-fast zoom surveillance camera is recommended for household indoor use, dual cameras + 3x ultra-fast zoom.

4 million high-definition, intelligent dual-camera system, short focus to see the overall situation, long focus to see details, and you can see clearly from far and near.
3x zoom magnification, details can be seen clearly.
Intelligent full-color night vision, two-way voice support.
Intelligent motion detection, intelligent tracking shooting.

 

5. Monitor corridor aisles
For the monitoring of indoor corridor aisles, due to the small scope and relatively simple requirements, from the perspective of cost, the basic model of the brand camera can be selected.
For example, the following two models support wireless WIFI, low-light full color, humanoid detection, and automatic follow-up shooting, and the price is within 200, which is very cost-effective.

 

 

For outdoor corridor aisles, it is not recommended to install in public areas such as corridors due to the issue of privacy in public areas. If it is really necessary, it is recommended to communicate with neighbors to avoid unnecessary trouble.
If you really need to monitor, it is recommended to choose a smart video doorbell/smart cat’s eye. These devices now also have many smart security functions, such as human body sensing, automatic alarm, automatic video recording, etc., which can enable you to ensure your own safety.

Considering the price factor, you can also choose the 5C version of the 360 ​​video doorbell. In addition to the 140° lens angle of view, which is slightly smaller than that of the 5 Pro, it also has the security monitoring function of the ipc-hdw3841tm-as. In addition, it also supports the use of a power bank.

The network cable connection is stable and reliable, the WIFI connection is simple and clean, and the traffic card method can be remotely monitored without relying on home broadband.

Some surveillance cameras also provide their own WIFI hotspot function, which can be viewed through the APP without connecting to the Internet, which can be comprehensively considered according to the situation at home.
4. According to the storage method, there are mainly three kinds of memory card, NVR storage and cloud storage.

A memory card, usually a Micro SD card or a TF card, is used to insert the camera to achieve local storage of video recordings, DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA NVR4208-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,DAHUA DH-NVR4208-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,NVR4208-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,DH-NVR4208-4KS2/L,NVR4116-4KS2/L Price,NVR4116-8P-4KS2/L price,NVR4208-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price,DH-NVR4208-4KS2/L price and it is also the most commonly used storage method for home surveillance cameras.

Another point to consider is that high-definition video requires a lot of storage space every day. At present, the mainstream memory cards in the market have a capacity of less than 512G, which cannot support large-capacity long-term video recording storage.

NVR (Network Video Recorder) storage, that is, network hard disk video recorder storage. Receive the video transmitted by the surveillance camera through the network and store, manage and playback. The advantage is that it supports multi-channel video signal access, and supports large-capacity, long-term high-definition video storage.

It is more suitable for some places that require centralized video surveillance and have high requirements on the recording cycle, such as shops, supermarkets, office spaces, factories, villas, etc.

Cloud storage is a network cloud storage service provided by security manufacturers. It is safe and reliable. Video recordings will not be damaged and not easily lost, which is convenient for subsequent investigation and evidence collection.

However, cloud storage is a continuous expense, which is usually purchased according to the storage cycle. Different manufacturers charge different fees. The following figure is a reference for the official cloud storage charging methods of ipc-hfw3541e-as and Lecheng.

Fourth, what factors should be considered when choosing a home surveillance camera?

In addition to brand and appearance, the selection of home surveillance cameras also requires comprehensive consideration of some equipment parameters and basic functions, including:

1. Camera resolution

Usually when we choose a camera, the first condition that comes to our mind is: to be high-definition, the high-definition here refers to the resolution of the camera.
Note: The picture is from the Internet, invaded and deleted

There are generally two versions about the resolution of the camera, one is 720P, 1080P, 2K, 4K, etc., the other is 2 million, 3 million, 4 million, 5 million, 8 million, etc. In fact, there is no essential difference between the two, just Different names for resolution.

The P here refers to the pixel value Pixel, which is the basic unit of the picture, and the resolution is the height * width of the picture.

To put it simply, 1080P means that the resolution reaches 1920*1080=2073600P, that is, the resolution is 2073600P, which is about 2 million pixels, so generally 1080P can also be called 2 million pixels. 4k refers to a resolution of 3840*2160=8294400P, which is about 8 million pixels, and generally more than 8 million pixels can be called 4K high-definition.

The higher the resolution, the higher the pixel value, and the sharper the image.

But for home monitoring, the higher the resolution, the better. The higher the resolution, the more storage space is required, the higher the occupation of home network bandwidth, and the higher the cost.

At present, the resolution of mainstream home surveillance cameras on the market is generally about 2 million to 4 million, which is enough to clearly see human faces and expressions in indoor environments. If there are higher requirements for the clarity and monitoring distance of surveillance video, Higher resolutions can be selected as needed.
2. Lens focal length

The lens of the surveillance camera is its core part, which determines the angle range and distance of monitoring.

Usually, the larger the focal length of the lens, the farther you look, the smaller the viewing angle range, DAHUA NVR4116-4KS2/L,DAHUA NVR4116-8P-4KS2/L,DAHUA NVR4208-4KS2/L,DAHUA DH-NVR4116-4KS2/L,DAHUA DH-NVR4116-8P-4KS2/L,DAHUA DH-NVR4208-4KS2/L,NVR4116-4KS2/L,NVR4116-8P-4KS2/L,NVR4208-4KS2/L,DH-NVR4116-4KS2/L,DH-NVR4116-8P-4KS2/L,DH-NVR4208-4KS2/L,NVR4116-4KS2/L Price,NVR4116-8P-4KS2/L price,NVR4208-4KS2/L price,DH-NVR4116-4KS2/L price,DH-NVR4116-8P-4KS2/L price,DH-NVR4208-4KS2/L priceand the smaller the focal length, the closer you look, the larger the viewing angle range.

The 2.8mm focal length lens is mostly used in monitoring environments in small spaces such as storage rooms, and the optimal monitoring distance is within 3m.

The 3.6mm lens can be used in larger indoor environments, such as living rooms, small shops, etc. The optimal monitoring distance is 3-5m.

The 6mm lens can be used in scenes such as family courtyards, balconies, doorways, etc., and the optimal monitoring distance is 5-10m.

The 8mm lens can be used in outdoor scenes such as roads and alleys, and the optimal monitoring distance is 10-20m.

In addition, some camera lenses are zoomable, and the size of the lens can be adjusted according to the scope of the monitoring scene, which is more flexible and convenient, but the cost will increase accordingly.

Usually, a 2.8-4mm lens is recommended for a home indoor surveillance camera. With the gimbal, it can monitor every corner of the room in a horizontal 360° without dead angle.

For a more detailed introduction to the focal length of the lens, you can refer to the article:
Alai: How to choose the focal length of the surveillance camera? After reading this article, you will understand 55 likes 6 comments on the article
3. Night vision function

At present, the mainstream surveillance cameras on the market all support infrared night vision function, on top of which there are starlight night vision, full-color night vision, and black light night vision.

Infrared night vision refers to the function that the camera uses the infrared emitting device to actively project infrared light onto the object in a dark or low-light environment, and the infrared light is reflected by the object and then enters the lens to obtain the image screen function, which is also the current mainstream. night vision mode.

The infrared night vision distance can generally reach about 10 meters, and some cameras can increase the transmission power to make the night vision distance reach 30-50 meters.

But the biggest problem with infrared night vision is that the picture is black and white and cannot present more details.

Starlight night vision means that surveillance cameras can still display color images in low-light environments.

Generally, a large aperture lens and a high-sensitivity sensor are used, which makes the incoming light more and the sensitivity better. Compared with the ordinary infrared night vision camera, the night vision effect can be seen more clearly and the picture is more delicate.

However, when the ambient light is lower than the infrared switching threshold of the starlight camera, the starlight camera will still switch to infrared night vision and become a black and white picture.

Full-color night vision means that the surveillance camera can always present a colorful and clear shooting picture under low illumination or even no light. When the ambient light is low or even no light, the fill light will be automatically turned on, so as to achieve full color day and night. .

The full-color night vision function will turn on the fill light, so it is not suitable for installation indoors. It is more suitable for places where high-definition image quality is still required in a dark or no-light environment, such as home gardens, roads, warehouses, underground parking lots, park etc.
