w to Improve The Effect of High-definition Network Camera Night Vision



2012-12-03 15:04:17 - problems come out during the using process and solution to solve them.

Currently the high-definition video surveillance with the sudden emergence and has rapid development on security market , but the night infrared effect remains to be improved. The writer would like to share with everyone on this topic according to his accumulated experience in the recent years .

Interference to HD network camera night vision effect for the following reasons:

The construction works.



HD network camera pixel is much higher than the simulation , in order to make better high pixel video, most manufacturers use IRcut to control infrared day and night, and the use of larger power infrared lights, The effort is better in daytime, but at night, it will be prone to the phenomenon of insufficient power supply.

Solution :

1, row 220V power line directly to the camera side, use small 12V switching power supply; wiring of the program is trouble , but the power cord diameter can be smaller, the need to use better DC12V adapter, do not use inferior fitness N “K9nM

2, DC power cord, use coarse diameter centralized power supply. The program is reliable, but the power cord is fairly thick and the line costs are relatively high.

3, In case of the distance is not too long, such as 30M, use the 4-5 and 7-8 lines to transmit DC12V, the transmission line area has doubled, it can significantly improve the quality of power supply. Used properly, it will bring higher comprehensive benefits .

4, centralized power supply end use DV24-48V switching power supply, power supply by cable, use lower buck module to reduce the voltage to high-definition network camera to DC12V. The program requires a certain circuit basis. The cost is lowest, with high reliability
