Vedard Security Alarm Technical Support

The oscillating object will make the microwave detector work, so it may also cause false alarm. In ancient times, the purpose of installing detectors in illegal intrusion routes was to prevent the illegal intrusion of criminals. Before determining the installation location, the main population of bu...

The induction of passive infrared detectors is closely related to the change of temperature. Both cold and hot vents and cold and heat sources may cause false alarm of detectors. For some low performance detectors, sometimes air convection through doors and windows can also cause false alarm.

Passive infrared detectors have two problems when they are facing glass doors and windows. One is white light interference. It is obvious that PIR has a strong suppression function on white light, but it is not 100% suppression. Therefore, the interference of strong light can be avoided by avoiding ...

Because passive infrared detector is a weak signal detection equipment, we must pay attention to some details in installation, such as height, sensitivity and so on. To install a passive infrared detector correctly, we must grasp the following information: firstly, we must understand the performance...

If you stop using refrigerators in winter, it will really reduce the life of refrigerators. Because the plastic inside the refrigerator is easier to aging at room temperature (after power failure) than at low temperature, continuous use can slow down the aging phenomenon and prolong the life of the ...

Nowadays, the dual-detector alarm is introduced on the market, which combines human pyroelectric infrared detection and microwave detection in the same group of detectors. It makes use of the performance of microwave not being shielded and insensitive to smoke, light and temperature changes, and com...

It is safer to use the door magnet as the detector, and it is impossible to miss or misreport, because the alarm signal is generated by the external force of the door and window when the crime is committed. No crime behavior will not produce alarm trigger signal, but the volume is large, and belongs...
