Install infrared cameras to pay attention to two issues
Author: guardly | Posted: 03.05.2012Infrared camera unlike ordinary bolt, its surrounding environment and monitoring targets requirements: the sharpness of the image produced by the ip camera in the most Minimum illumination is measured, its black and white stripes television signal test cardthe black reflectivity close to 0%, white reflectivity greater than 89.9%. While in the on-site observations, we sometimes do not have such a condition, such as: leaves and grass, and some black things low reflectivity, contrast is very small, it is difficult to get a clear image, the white stuff high reflectivity contrast on easy to get a clear image.
The infrared camera is a passive infrared; In other words, the infrared effect is not only the infrared light quality CCD's sense of red reflection intensity of the illuminated objects ... In other words, the same megapixel ip camera, a white clothes may be clearly seen in the one hundred meters, while dressed in black, could not clear 40 meters; Then there are the customer experience: the manufacturers generally will tell you buy 12V1000mA power, if the purchase poor quality of power supply voltage and current lack of or too large, will cause the device is not working. Infrared itself, physical properties, and some can not be changed, so the infrared has been some controversy. We are doing the best, but we can do better!
Customers need night vision network camera, during the day was better but pay more attention to the night vision effect.
15-25 meters, Sony, Sharp, the board has done. More than 30 meters, all the SONY boards; 20-70 m has to do with a fixed lens; do one of the infrared zoom. If a customer needs a long-range infrared surveillance ip camera, infrared zoom one machine, the quality and effectiveness of recommendations do have protection, night vision up to 150 meters or more; (market, good customer feedback effects).
To sum up: the infrared network camera is installed,
1, try to avoid direct light;
2, the place of the infrared mini ip camera exposure, try to avoid the straight on the radio with full black object, the open air, the water absorption of infrared light objects.
