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
