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 brand names.

SD59225U-HNI Outstanding video imagery

The PoE type cameras greatly assisted with the design and installation of the cable infrastructure and kept costs down, negating the need for additional PoE switches due to the length of cable runs.” Graham Denny, Director of Logistics at Pets Corner, said: “When building our new National Distribution Centre, we wanted a system that would not only give us maximum security but assist in maintaining operational and health and safety standards.”

The results from Urban Security Systems are excellent, providing us with outstanding video imagery, which is simple to use on my laptop, desktop and phone. Therefore I would highly recommend both the Dahua CCTV system for anyone with a similar requirement and of course Urban for their great installation, large parts of which were carried out safely and professionally while we were operational.”


SD59225U-HNI 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 element 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.

SD59225U-HNI High Clearness 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 deliver hd video.

SD59225U-HNI Low Illumination Performance.

Low illumination is one of essential aspects to judge security cam 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.
