What Are IR Lamps?

Infrared light is an abbreviation of night vision monitoring infrared light, which is a supplemental light device that cooperates with surveillance cameras to collect images at night. The light emitted by the infrared lamp has two wavelengths of 850nm and 940nm, both of which are invisible light. It has the characteristics of concealment and energy saving. It has been widely used in the field of security monitoring in the past 10 years.

The power of the infrared light conversion is fixed, if you want

LED infrared light products are divided into two categories with red exposure and no red exposure.

Products with red exposure use infrared with a wavelength of 850nm

1. Red exposure of infrared light:

Red exposure means that the infrared lamp has visible red light, and no red exposure otherwise.

2. Explosion-proof infrared lamp:

High-strength materials are used to make infrared lamps that can protect from ordinary external forces.

3. The influence of infrared light wavelength on infrared light:

The longer the wavelength, the smaller the red burst, or even no red exposure. However, the lower the efficiency of infrared light, the higher the heat of the infrared lamp.

4. Use infrared light:

The most important thing is the completeness, and the completeness of the camera, lens, protective cover, power supply, etc.

5. Camera selection:

Can not be shared with ordinary color cameras, it can not feel the infrared light, you should choose a black and white camera or a special color camera (auto-sensing infrared, color black and white automatic conversion). The camera has an automatic electronic shutter function, AGC automatic gain control function, and the lens has an automatic iris to adapt to large changes in day and night illumination. Infrared lamps have strict requirements on voltage, and should use AC 24V or DC one-to-one regulated power supply as much as possible. The light is more complicated, so it is better to choose a larger irradiation distance outdoors than indoors.

6. In addition to matching, consider the following factors:

a) In the case of infrared lamps, leave room for selecting the irradiation distance of the infrared lamps.

b) The shield also affects the effect of the infrared lamp. During the transmission of infrared light, the transmittance and reflectance are different through different media. Different window glass, especially the automatic defrost coated glass, has different attenuation of infrared light. In addition, it may reflect infrared rays, causing the image to be white or iris.

7. Other common sense of infrared lamps:

With the rapid development of infrared night vision systems, infrared light production and supply manufacturers will also increase, but red light products are not as easy as some people think, and conditions are different in terms of technology, testing equipment, etc. I hope users to compare them more Choose carefully. Users must read the instruction manual carefully before using the infrared light, especially the precautions to ensure the safety of personal equipment. Check whether the compatibility mentioned above meets the requirements and whether the influencing factors to be considered are taken into account. If the requirements are not met, the equipment used can be adjusted in a timely manner. The user should not increase the supply voltage without authorization, because the infrared lamp is designed in consideration of both its full irradiance and its safety and reliability. Increasing the power supply voltage may cause the infrared lamp to burn out, and it should not be dismantled and changed without authorization. If this is done, the manufacturer may no longer be responsible for repairs. If there is a problem with the infrared lamp, you should contact the manufacturer or supplier.
