Concerning Dahua.

Dahua Modern technology company is the No. 2 leading maker in China, the business concentrates on safety and security cam devices and also make anything from the standard residence system to the business safety and security system. The majority of Dahua products are at the budget-end of the marketplace, yet they manage to keep adequate quality in their products to be able to take on some other global brands.


Precise Pan & Tilt Cruise.

Frying pan & Tilt as the core elements of network PTZ dome electronic camera, it is additionally the vital element why PTZ dome electronic camera is made up a lot of the market share in commercial video clip surveillance applications. As the essential component of PTZ dome video camera, it provides the sophisticated technology of electric motor mechanical structure as well as control, it’s the driving power to frying pan & tilt electronic camera. The smooth running of pan & tilt rotation depends upon whether the complete electric motor’s performance is excellent. Currently, the widely used motors consist of 2 kinds: DC motor as well as Stepper electric motor. All the dome electronic cameras in this test adopt stepper motors, stepper motor functions establish its pulse checking can be driven below the discrete control systems. To rotate the cam from one position to another setting, at a continuous speed, only requires to compute the difference of variety of actions between both locations. As a result of this rotation style, PTZ camera is suitable for large location video monitoring.

DAHUA SD59225U-HNI  High Clarity in Genuine Tracking Scene.

In real-time tracking scene, the adjustments of environment may bring some difficulties to network rate dome electronic camera. Such as fog, strong light, rain-storm and so on, these 4 PTZ cams are able to withstand/overcome the severe problems to supply hd video.

DAHUA SD59225U-HNI  Low Illumination Performance.

Low illumination is one of essential aspects to judge security video camera performance. Put network video cameras into dark box, as we by hand reduce the lighting to examine the threshold value when cams alter image setting from shade to grayscale. Among them, Dahua and Uniview, as well as Tiandy have much better efficiency, When Dahua network camera operates in minimal lighting is 0.00 Lux (real Lux is in the variety of 0.001 – 0.009 Lux) condition, the video camera still can capture clear pictures, as well as virtually no picture sound, its reduced lighting performance is outstanding.

Network PTZ dome cameras enter era of high definition, the development of network PTZ dome camera meet the needs of market. PTZ dome camera itself has the great flexibility, pan & tilt mechanical design with powerful optical zoom lens, it’s inevitable choice for large video surveillance monitoring area


DSS Express video management system

The installation also includes Dahua’s DSS Express video management system, enabling users to view images only relevant to them, two Dahua 32-channel 36 TB NVRs (Network Video Recorders) and 12 ruggedised network PoE switches.

The site consists of freight container storage in one section and road haulage transport in the other. It was previously equipped with an ageing analogue CCTV system, elements of which was in various states of disrepair and had become unfit for purpose.

High definition site monitoring

The objective for the new system was to provide high-definition monitoring of the whole site, at all times, for security and logistics managers to be able to have access to images relevant to them, partitioned by the Dahua DSS Express video management system.

The installer, Richards CCTV, was tasked with providing a perimeter protection solution, as well as a range of PTZ cameras around the site. The biggest challenge was the installation of the network infrastructure, with multiple fibre links between remote buildings and the central office. This was achieved using ruggedised network PoE switches with 2 GB ports for high-speed connection.

Enhanced security and visibility

Security is key for us, but we also use the system to have good visibility of our operations”

Richard Harte, General Manager at the Cannock terminal, said that good security and visibility of operations is essential for such a large and busy site with a bonded storage area.

He stated, “With the previous system, we came to recognise how poor our sight over the depot was. Security is key for us, but we also use the system to have good visibility of our operations, as well as for health and safety and training purposes.

Richards CCTV, efficient system installer

Richard Harte adds, “We found Richards CCTV to be a professional, cost-effective and efficient installer, with a fast response for their maintenance operation. I am also particularly impressed with the quality of the system components and the way we can view, and control cameras remotely with no latency.

Richard Harte and his team are so satisfied with the solution that they are advocating its rollout across other Pentalver sites and have shared their recommendations with the company’s safety team.
