What you need and how to choose an IR illuminator for your video cameras

It is often necessary to organize video surveillance in the dark. How can you send a comrade hidden, without letting the object be illuminated with visible light? Infrared searchlights will help. In the article, we will analyze how the devices are described, how they work and how the characteristics of the machine work.

What is Infrared (IR) Treatment?

For the beginning, consider for a table with electromagnetic emissions from different lengths to valnata or, on the other hand, honesty.

Masa with electromagnet

Somehow sevide from the table, nai-kasata longjina on vlnata with the maximum frequency of e-gama and X-ray exposure. Tova e taka is named radiation-penetrating radiation. A trace of light is visible behind the human eye - from violet to red. Ako continue and paint the chastotata, it’s a little bit of an eye of the evening and the reception is ilchvaneto kato light, but still everything is related to light. They will call it infracherveno. With a natural increase in length by length, it is reduced by a break in girth on a conventional radio wave.

Why is the infrared range interesting? First of all, that one is not visible from the human eye, that is, it is invisible. And second, it's perfectly recorded from a modern camcorder.

Protect yourself in need of an IR illuminator for video surveillance

It’s not difficult to figure out how infrared projectors work.Yes, let's suppose that they lit up with such a device of an object, which is sa varhu of an object in a dark darkness. Behind the chiveshkoto eye is not visible change: ty kato beshe dark, stop.

But, as we all know, the matrix on the video camera is perfect for seeing the infrared spectrum, which means, in some way, seeing and object, illumination from the spotlight. According to Tosi, the infra-red illuminator began, making the spectrum invisible for us, and it is an ideal solution for organizing video surveillance on the top of the non-illumination of the object.

Is it any harm for you?

Thy kato radiation from a distance to a vlnata, little by little from the vision of the spectrum, it is dangerous for horata (referring to penetration), you can guess, if you lie under the vision of the spectrum, it’s dangerous. Tova is completely wrong. It’s a lot of radiation, soils with ultraviolet radiation and in a mountain, it’s dangerous, it’s not very penetrating far into the weave, from the gi, but it has such an ionizing property, which is somehow debilitating in a cage on a heavy.

Please do not claim such properties. You can’t dory and “burn out” under it, somehow under the ultraviolet light is hidden. Do not swear leather and eyes, not penetrating into the weave and completely harmless. In terms of Tosi, it is absolutely safe to start and use an infrared illuminator.

Main features and specifications

Infrared projectors, such as ejection devices, characterization data, basic tracking.

Save voltage… Depending on the purpose and power, the device can store everything either from a 220 V network, or from an adapter, and from its own battery.

Light source... In infrared illuminators, a cathode light source can and can be used to mount lamps with a special filter, gas discharge lamp or infrared LED. The last type of source is funny, but make two replacements for the sake of high efficiency and, for the most part, operational life.

Power... Infrared projectors, similar to conventional lighting, can and have different power: from one to ten watts. Kolkoto - high power, sensible - brightly shine the projector, but also more consumer.

Girth... A characteristic that somehow determines the "girth" of the spotlights and the quality of the lightening. A device with low power shines close and illuminates objects a lot mediocre. Devices with a high power allow you to monitor video surveillance from a naked distance and get a kinder and brighter picture.

Cover the spotlight from a low power (left-handed shot), leaving a lot of whatever you want, a powerful device can illuminate objects at a distance of 100 meters

Ygl for visibility… Depending on the design, infrared illuminators can capture certain radiation sectors. Kolkoto on-golyam eaglt on visibility, sensible on-golyama more bdezonata on lighting, but in a lower girth in comparison with a device with a tight beam of power.

Length on vlnata. From the basin, the characteristic depended on the work on the spotlight, which is still visible with the naked eye. Kolkoto-golyama e dalzhinata on vlnata, sensible, a little white work on the device for a person, but sensible in terms of poor quality, the painting was received from the camera.

Selection criteria

When choosing a projector for a video camera, try and imate four main characteristics:

1. Energy consumption. Kolkoto for a low consumption of energy, a long-term projector can work autonomously or consume a little energy from a source. Whenever you choose a device according to this criterion, you can clearly understand it, together with what equipment and under what conditions you can use the device.
2. Illumination coverage. If an object is small (a flock, an entrance, etc.), then a long girth is not necessary - this is an additional loss for a bet and electricity. But for yes, observe, yes, we say, a parking lot, a hangar or a warehouse, check the winding device with the golyam obseg.
3. Ygl for cover. Nay-dobriyat option e infracherven illuminator ssshchiya or a little wide ygl to cover the kato used a video camera attached to it. Ako glyte is small, you can go to the camerata yama and bdat from crawling on the spot. On goals - the searchlight destroys energy more, cato illuminating areas invisible behind the camera. The only exception may be a wide-angle searchlight, which will light up some of the cameras.
4. Length on vlnata. Infrared range e between 730 and 900 nm. When choosing a disputed device for the device, the criterion of turbulence and all the earth foresaw did not itself give a person a bright light with an open eye (that is, a light with a length of 400 to 700 nm), but also a characteristic for the camera. Not every camera sees good in the whole infrared range. Osventova, kolkoto kasa e dalzhinata on vlnata on the projector, sensible, more clearly, the picture on the camera.
