在CCTV摄像机设计精巧装置，确保长寿命和清晰图像

A.防雷设备：

独特的隔离式防雷 保护 电路，它可以有效地分离脉冲电压高达5000伏，由特殊的LC滤波电路的补充，它可以有效地隔离和吸收雷电由破坏性脉冲产生高压，并因此大大降低了照相机的雷击破坏率。

B.无闪烁的LED设备

特殊设计的红外灯开关电路实现实现无闪烁的功能，当红外开启/关闭。 消除了闪烁和灯光不稳定的现象，当相机开启/关闭。

C.出色的色彩还原设备

精心设计的电路方案，反复调试程序软件可确保出色的色彩渲染，使得相机无论是在室内还是室外，都可以还原原始色彩的真实场景。

D.高效率恒流驱动器设备

我们的红外产品采用高效红外灯驱动电路。 电路的效率是95％以上，且其误差仅为0.3％。 当电源电压是标准电压的范围之内 - 50％到+ 50％的变化，红外灯驱动电流变化几乎是0.3％，也就是说在电源电压急剧波动不会影响正常的灯的光与 红外灯的寿命。 一般电阻限流驱动器和降压型恒流驱动电路不能做到这一点。

E.低照度设备

采用了索尼新的高灵敏度，低照度HAD CCD芯片，卫相机摄像能力大大在弱光的提高，也大大扩大了使用红外距离，卫相机的光灵敏度比传统摄像机高136％。

F.低红外光的衰减设备。

通过使用大核心，高功率红外LED管，高精度和高效率恒流红外驱动电路，我们的CCTV摄像机的红外光衰减超低。 1年以内，光衰减为3％，和光衰减五年内30％

Smart design device in the CCTV camera to ensure the Long life and Clear image

A. Lightning protection Device:

Unique isolation type lightning protection circuit, which can be effectively separated as much as 5000 volts of pulse voltage, supplemented by special LC filter circuit, it can isolate effectively and absorb lightning high pressure produced by the destructive impulse and, thus greatly reduces the lightning damage rate of the camera.

B. Flicker-free LED Device

Special designed IR LED switch circuit implementation realizes flicker-free function when IR on/ off. Eliminates the Flicker and lights unstable phenomenon when CAMERA on/ off .

C. Excellent color reproduction Device

Carefully designed circuit scheme and repeatedly debugging program software ensures excellent color rendering, making the camera whether indoors or outdoors, can be realistic scenery of reduction of the original color.

D. High Efficiency Constant Current Driver Device

Our infrared products adopt efficient infrared lamp driver circuit. The efficiency of the circuit is more than 95%, and its error is only 0.3%. When the power supply voltage is within the scope of the standard voltage of - 50% to +50% change, infrared lamp drive current change is nearly 0.3%, that is to say sharp fluctuations in supply voltage does not affect the normal lamp light and infrared lamp life. A general resistance limit flow driver and step-down type constant current drive circuit can not do it.

E. Low Illumination Device

Using SONY new high sensitivity, low illumination HAD CCD chip, Guardian camera image pickup ability is greatly improved in weak light, also greatly expanded the use of infrared distance, the light sensitivity of the Guardian camera is 136% higher than traditional cameras.

F. Low infrared light attenuation Device.

By using of the great core, high-power infrared LED tube and high precision & high efficiency constant current infrared driver circuit, our CCTV camera's infrared light attenuation is ultra-low. Within 1 year, the Light attenuation is 3%, and the light attenuation is 30% within five years
