What Are The Components of Door Alarm Systems?

A door alarm is composed of a sensor and a receiver. The sensor is installed on the door frame while the receiver is installed on the door itself. The sensor will be the one emitting the magnetic field, waiting to be breached. On the other hand, the receiver will be in charge of emitting the alarm, waiting for an intruder signal from the sensor.

What Needs To Be Considered When Buying An Office Door Alarm System?

Simple models of anti-burglar door alarms only have the basic features: they are turned on and that’s it. Other more complex models have the ability to regulate the sensitivity of the magnetic sensor, have a strobe light or are capable of being controlled by a remote control.

You may even find door alarms that are hanged at the knob of a door. In case an intruder touches the knob, even while wearing gloves, the alarm will start. This portable door alarm can be very useful for travelers who wish to have extra security in their room.

Hardwired door alarms can be even more complex, since most of the times they are connected to a security central. This implies a higher cost in maintenance and systems.

All of these features need to be taken in consideration before buying. A good rule of the thumb is not to buy the cheapest door alarm, or the most expensive. Do you really need a remote control for turning it on or off? Look for the ones that have average prices.
