Constantly improved on technology in electronic technology brought to the point of being able to be illuminated on the object (object) from the infrared light, invisible behind the human eye, but visible from the sensor on the device at night. Tova vi allow and hide from others the observation of the desires of the object in the dark or with a weak natural light. In FIG. 1 showing the girth on the spectrum on the scab, cut from the slate.

Oriz. 1. The solar spectrum is isolated

For yes, pick up the visibility on the object, NVG sensor using an infrared fenerche or a spotlight. The view of the infrachervenoto fenerche does not distinguish much from the ordinary. There is more to be seen in the source, on the light, on the illuminator. So, in a typical LED, they use, which emits visible light, and the width of the light (λ) is in the range from 0.4 to 0.7 micrometers, and in the IR of the illuminator λ \u003d 0.7–1 µm.

Use on infracherveni lightline for video surveillance

Tryabva and see what they enhance on the image (amplify on the image) on the camera, it’s much simpler from our eyesight. That reaction itself to the silat to the reflection of the light from the object. Ako nyama svetlina, meaning nyama and image… In order to obtain an image, it is necessary to determine the field of illumination for observing an object. Time the lamp for strength on the image, it is only visible and visible at illuminance from 0.0005 lux. In FIG. 2 images shown with and without infrared lightening (for comparison).

For the hopeful work of this task, the initial range for the infra-cherries spectrum, that is, the trace of the worms for the scars, blooms. Nyama clear border. Select 4 bands:

• 730-750 nm,
• 830-850nm
• 870-880 nm,
• 930-950 nm.

This source is based on infrared LEDs and laser infrared diodes. LED light emits a spectrum from chastity, that is, it gives a meco radiation, and laser light gives a hard radiation. We offer all laser emitters with a third-party optical system. Takiva emitters form a cramped beam.

Reflector e designing and forming a light beam. The geometric size e is an isosceles triangle with a top at the source to the light. Ъglt on decoction e is determined by 0.5 by the rest. Average gl on decoction is 40-80 degrees (gl). It is important to understand that, with an increase in the distance on the kneading, the distance for the background clarification of the painting and the power on the spotlight is determined mainly not by the girth, but by the area for illumination. In FIG. 5 showing different types of light lines.

Oriz. 5. IR light line for video surveillance

When you copy the models, they are adjusted to light areas. The reflector can be made of metal or plastic and meet the required heat resistance. Infrared diodes heat up in time for work. Kolkoto in a golyama e tyahnata power, sensible more heating. The surface on the reflector is textured or smooth. Pre-reflector and bream, some pre-reflector and infrared diode from the surrounding environment. Manufactured from glass or plastic.

The power at the transducer ranged from milivat to a dozen watts.

Possibility of options for the operation of the checkbox in the "mode" element. For example, when clarifying the "chameleon" type, you can follow the options:

• strobe;
• lighthouse;
• SOS;
• control on emission: high, medium, low, minimal;
• remotely.

Use all different types of devices for fixing on IR fenercam devices for night vision. You can easily cross from the sam relsite to the Weaver and Picatinny, ¼ adapters for the socket for the stand, helmet or strings for the head, mounting for small arms is universal. There are more differences between the boards in the width of the slots. Ribbon on Weaver ima = 0.180″ and relsata Picatinny = 0.206″, and between the center is 0.394″ and long is 0.118″.

Km tyaloto se will impose strict scrutiny. You tryabva yes bjde leka, shock-resistant, waterproof. Expenditure on a rollback on a pistol. Made mainly from anodized aluminum alloy of high quality, which works under meteorological conditions.

Advantages and disadvantages

Offers include:

• IR treatment is not safe for the cold and near environment.
• Osiguryava is unbelievably illuminated to protect the object.
• Used for external brightening, adjusting the quality of the image. Maybe put it in any convenient place. Solving problems with graded lighting. Yes, you can choose the right ygl on the lighting, but you can choose a device that is divided by power, girth and coverage.

Insufficiently turn on the image of this or that when receiving black-and-white on a color camera... Smooth objects (zero or rivers of surface, glare of vision, shoulder or caress of battle, shot, brightness on the background) reflect infra-black beams and create a loop from the air into the image. Dust, rain, mist, flying insects and stings hinder the video image.

How can you direct yourself

If you wish, you can send your own IR lighting with your own system for video surveillance. For yes, send a comrade, tryabva, you know, base on electrical engineering, the principle of operating on electronic equipment and the ability to work in practice. Nay-lesniyat start and process the preparations. LED fenerchechange to visible light and change the emitter from infrared LED or laser diode. In the meantime, do not take it better if you use the laser diode for open places (as necessary, for illuminating at a far distance) and the ordinary LED is in the closure of space. In FIG. 6 showing a set of video surveillance for a villa or office.

Oriz. 6. Set of equipment for video surveillance

Protect the system for video surveillance, determine which zone the turbulence is and where it is observed, where and place video cameras and, if necessary, external IR illumination (send a rough plan). For example: video cameras - broy, view. Video recorder - 1 pc. Protect, backlight - quantity, model. Grab the kit you need from the store. Next, mount the kit on the ground.

Not everything is wrong with IR, light in the eye - maybe burn out the cornea in the eye. Ako yama enough clarification, you can add a little infrared diode.

For yes, they nagryavaneto the emitter and the consummation of energy, all because of the impulse voltage with an adjustable work cycle, that is, the diode flashes. The ratio is temporarily turned on and off on the LED. In FIG. 7 Display the output voltage for the LEDs pulsed.

Oriz. 7. Diagrams for voltage regulation from 10% to 90% 

In this way, the block, which is one of the options, is based on a circuit based on an integrated ne555 timer with a powerful transistor.

In FIG. Figure 8e shows a schematic diagram of a pulsed lock with backlight voltage.

Oriz. 8. Scheme for regulated storage on LEDs with backlight

Verigata can be sloben on a mock-up scarf. Might be purchased at the same time with the necessary radio parts in all the shops behind the radio.

The integrated circuit NE555 is controlled by a pulse generator. Before it is ready for operation, it is necessary to set the mode to work with the help of the external part. Shown is a chain of design and work from a source of +12 volts. Elements C1, R1, R2 will set the backlighting mode.From exit 3, this is by preventing the R3 limiter from storing the key T1 (field effect transistor). That premahwa natovarvaneto from the switch 3. The power supply for the backlight is selected by choosing the VT1 type. The power on the resistor is 0.125 watts. Change R1 exchange the frequency for the initial impulse voltage. When impulsively stored, the diode gives more light power, which is broken off when stored with a constant voltage. Light on the diode can be checked with a camera on a mobile phone or camera. There is still light on the screen.

Important. When choosing a tryabva and this, it is foreseen that the device for infrared lightening and nightly vizhdanye tryabva and work in an honest range.
