Most Common Problems with Infrared Cameras

Now the market has become the most common product in the field of surveillance of high-definition infrared video cameras. According to the statistics of the relevant departments, high-definition infrared video cameras have firmly occupied the first place in the surveillance camera market. So how to safely use infrared video cameras?

1. The infrared video camera waterproof effect is not ideal because of fogging

General infrared video cameras are sealed in design, with protection level up to IP66. but the infrared lamp will begin to work and will generate a lot of heat, while the heat dissipation effect of the shell is not enough and the machine itself is not well sealed, resulting in the machine after a period of time, inside more or less will appear vapor, affecting the monitoring effect. This part of the manufacturers use breathable design, increase the ventilation valve to facilitate an external temperature exchange, some use nitrogen, to ensure that the machine is inert gas, to ensure that there is no water vapor.

2. The infrared video camera night vision effect

This phenomenon is mainly manifested in the effect of flashlight or distance is not enough, etc.. This problem is mainly caused by the angle and function of the infrared lamp, infrared video cameras used by the infrared lamp peak wavelength in 850, the angle from 5-60 degrees can be selected, when the infrared emission tube angle is smaller, the farther the irradiation distance, the more obvious the effect of the flashlight, and vice versa, the larger the angle is no flashlight effect, but the distance is greatly reduced, to solve this problem is mainly to look at the infrared emission lamp GHOPTO Techs's infrared zoom lens camera products all use the industry's first-class infrared lamps and lenses to ensure the night vision effect, completely eliminate the flashlight effect.

3. The infrared video camera daytime off-color

Infrared video cameras of inferior manufacturers of color in the daytime will be more or less bias, the most direct reason for this is the problem of the camera filter, the general infrared video cameras use a certain percentage of infrared light through the double-pass filter, the advantage is the low cost, but because the natural light contains more infrared components, when it enters the CCD will interfere with color reproduction, such as green plants become gray and so on. GHOPTO Techs, a professional infrared camera manufacturer, use IR-CUT dual filter effectively solve this problem, IRCUT dual filter consists of an infrared cut-off filter and a full-spectrum optical glass, when the daytime light is sufficient infrared cut-off filter work, CCD restore the true color, when the night light is not enough, the infrared cut-off filter automatically moved away, the full-spectrum optical glass began to work, so that the CCD take full advantage of all the light, thus greatly improving the infrared performance.

4. The infrared video camera heat problem

The most important factor affecting the life of the infrared lamp is the temperature, due to the configuration of the infrared lamp that generates more heat, the infrared lamp in the start, the entire working time period (in 12 hours) in the front of the swir inspection will have heat concentration, will affect the normal work of other components such as cameras.

GHOPTO Techs infrared video camera by using a constant current power supply, using the law of pulse width modulation to keep the infrared lamp current constant, so as to reduce the heat of the infrared lamp, no matter how the external input current fluctuations, through the circuit into the infrared lamp current is very stable, so as to ensure that the infrared lamp to play its own maximum efficiency, extended life.
