Infrared spotlights for video surveillance – an advantage in the dark

Infrared illuminators for video surveillance systems are special devices that are used to provide night vision in low light or complete darkness. IR spotlight works on the principle of infrared radiation, which is invisible to the human eye, but provides sufficient light for the operation of video cameras at night.

The main component of infrared spotlights is special LEDs (IR diodes), which generate radiation in the infrared spectrum. Such LEDs provide high energy efficiency and a long operating period. They are placed in special lattice or optical systems that direct light in the desired direction, providing uniform illumination of the observed area.

The standard design of infrared spotlights usually includes a case of metal or durable plastic, which protects the device from environmental influences and provides heat removal from LEDs, increasing their service life. On the housing can be placed adjustable fasteners for easy installation of the spotlight on the wall, ceiling or support structure.

IR spotlights for video surveillance are important components in ensuring the safety of objects, especially large ones, at night and help to carry out high-quality video surveillance even in conditions of complete absence of light. Their use is widespread in the field of protection of large facilities, public transport, industrial enterprises, as well as in home video surveillance systems to ensure the safety of housing and household plots.



What are the advantages of using IR searchlights

Infrared spotlights for video surveillance systems are characterized by the following advantages of operation:

1. Maintaining visibility in low or no light – provide high-quality lighting in the dark, allowing video cameras to maintain the image in normal quality.
2. Expansion of the field of visibility – thanks to infrared radiation, the infrared spotlight increases the scope of the video camera, making it possible to cover large areas of observation objects.
3. Improving video quality – by obtaining a sufficiently good image in dark conditions, video cameras can record clearer and more detailed video recordings, which facilitates the identification of objects and events.
4. Invisibility to the human eye – the radiation generated by IR spotlights is invisible to the human eye, making them invisible in the dark to potential intruders and not disturbing the background of the environment.
5. Energy savings - the device consumes less energy compared to conventional lighting, while activated by the surveillance system only in darkened conditions.
6. Durability and reliability – IR spotlights have a long service life and a high degree of reliability due to the use of quality materials and components.

In the modern market there are various models of infrared spotlights with different parameters, which allows you to choose the most suitable option depending on the specific needs and operating conditions.



Important characteristics of infrared spotlights

The proposed searchlights for surveillance cameras can usually differ in the following characteristics:

• Power voltage - can be in models from 12 to 220 Volts for DC or AC networks, which provides the possibility of connecting to different power sources. Also, the presence or absence of a built-in power supply depends on the specific searchlight model and the requirements for the power system;
• Power consumption and current – different models may have different power consumption and current depending on the LEDs used and the overall design of the device. Usually they range from several to tens of watts and up to one Ampere;
• range - can be from 40 to 140 meters, which is determined by the power and number of LEDs, as well as the optical characteristics of the spotlight. Increased range allows to provide high-quality coverage of large areas or objects of observation;
• lighting angle – most often from 30 ° to 85 °, which determines the width of the lighting zone and the uniformity of the backlight;
• wavelength – standard about 850 nm, which corresponds to the infrared range and ensures the invisibility of light to the human eye;
• The number of LEDs can range from 4 to 96, depending on the power and intensity of the lighting required. More LEDs provide brighter and more uniform lighting;
• housing material – often made of metal, which ensures the strength and reliability of the device in various conditions and operating environments;
• Degree of protection from external influences – usually have a degree of protection IP65 or IP66, which provides effective protection against dust and moisture and allows the use of floodlights both indoors and in open areas;
• resistance to temperature changes - ensures the normal operation of searchlights in a wide range of temperatures (from -35 to 40 ° C), which is important for use in various climatic conditions;
• body color – as a rule, the searchlight body is made in white or black, which provides a good aesthetic combination with the interior and other elements of the surveillance system.
