Security Systems
Security is the condition of being protected against danger, loss, and criminals.

Difference Disjuncture GFCI
The role of difference disjuncture:
- Protection circuits against over-current due to overload or short circuit.
-Protection of persons against indirect contact (current leakage to ground).
Difference Disjuncture GFCI
The differential switch
He created a monitoring circuit and does not cut it in case of leakage current to ground.Level of immunity: 200A peak following periodic wave 8 / 20 microseconds.Operating voltage 230 V.Mechanical life cycle (on-off): 20 000
CCTV
CCTV(Closed Circuit Television Cameras) camera systems give the user the ability to observe several areas of a home or workplace simultaneously. These images can also be recorded on a digital video recorder or a network video recorder; either being very useful in the instance of an unfortunate event or crime.
Choice of Camera
Fingerprint
Cards can be stolen, replicated or shared.

Hand Key biometric access
Iris Scanning
Iris scanning measures patterns on the colored part of the eye - the iris.
your eye is 3 to 10 inches from the camera .
When the camera takes a picture, the computer locates:
The center of the pupil .
The edge of the pupil .
The edge of the iris.
The eyelids and eyelashes.
They also allow more than 200 points of reference for comparison, as opposed to 60 or 70 points in fingerprints.

Alarm Security Systems
An optical sensor uses a straight line of light from the transmitter to receiver.
In the presence of smoke the amount of light received by the receiver and decreases the electronic alarm is initiated.
Ion Detector
Americium: radioactive element - source of alpha particles ionize the atoms of oxygen and nitrogen in the air in the room.
Free electrons (charge -) to + plate Positive ions (+ charge) to the plate –
Appearance of a weak electric current and constant between 2 plates detected by the sensor electronics.
The presence of smoke in the room break the current (smoke particles absorb alpha particles and thus reduce the ionisation).
The smoke detector point deficit in current between the 2 plates and spear the alarm Electronics .

Gas Alarm
Largely used in various industries, we manufacture and offer area gas alarms.
These alarms come with audio and visual alarm indicators.
These alarms have LED displays that are bright and hence easy to read.
