Almost everyone knows what an LED projector with a motion sensor is. These devices are now quite popular, they are used for security purposes, for lighting controlled territories and in the private sector.
A motion sensor with a spotlight is indispensable if you decide to organize economical lighting of the territory, the entrance to the house, gate or gate. They are usually used where there is no need for constant lighting.
The motion sensor with a searchlight is an infrared motion detector and directly a lamp. The use of such devices will greatly facilitate the organization of protection of the object you need at night. So? a sensor with a spotlight configured to the entrance of your office will scare away the attacker with a sudden light and attract the attention of passers-by. In this way, the perimeter of the protected area can be protected, the light that comes on will let the guard know that someone is in that place. In order to enhance the effect, the motion sensor with a spotlight can be combined with sound sirens connected directly to the lighting control circuit. On the one hand, such protection is quite primitive, but on the other, it is simple, economical, and quite effective.
Indispensable motion sensor with spotlight complete with home
background system. Lighting the site in front of the doorphone panel immediately at the time of the call is very convenient for the owners, there is no need to light the site throughout the night. In this way, energy is saved and the lamp life is increased. You can combine such devices with CCTV cameras, so when the motion sensor is triggered, not only the lighting will be turned on, but the video signal will be recorded.
For ease of use, the design of the device provides for the adjustment of the sensitivity of the motion detector. It can be set to HIGH (high), in which case it will respond even to the smallest movements, and LOW (low), in which case the sensitivity is reduced. In some models, such adjustment can be carried out smoothly, that is, you can set any intermediate value. In addition, it is possible to adjust the time during which the spotlight will remain on (most often
adjustment is made in the range from 5 seconds to 10 minutes). If during the operation of the spotlight a repeated operation of the motion detector occurs, the countdown will begin again. The third setting of the sensor is made according to the level of illumination, to exclude triggering in the daytime.
Connecting a searchlight with a motion sensor begins with determining the installation location and the area that it should illuminate. With a mounting height of 2.5 meters, the effective tracking area of the detector is 12 meters. The device is mounted on special brackets, after which it is connected to a 220 volt network. Typically, to supply power use a ball screw or PVA wire with a cross section of 0.5-1.5 mm 2 . It is customary to lay the wire in a gaffrotube (diameter 16-20 mm). That, in fact, is all, ease of installation and connection - this is one of the advantages of devices of this type.
