How To Improve Your Home Security By Choosing The Right Motion Detector

A home alarm system will not be complete without the addition of motion sensors. A motion sensor detects the presence of an intruder inside your property by monitoring movements in a selected area. Several models of this device are currently available on the market.

There are two main types of sensors you can choose from, which are the microwave motion sensor and the infrared motion sensor.

The microwave motion sensor works by bouncing microwaves on objects around it, and measuring the time that each microwave returns. If there is a moving object or person in its area of coverage, a wave of different frequency is returned which sounds the alarm.

These sensors have quite a good range and can cover a wide area. It is also possible for you to hide these sensors behind objects as the microwaves they emit can penetrate solid objects. The major downside to these sensors is their sensitivity - their operation can be negatively affected by lighting and radio signals.

If you decide to purchase one of these systems, it is recommended that you hire a specialist to install it for you. This will guarantee that the device's settings are adjusted for optimal performance.

The infrared system is a far more common choice that is found in many homes across the country. They are generally more reliable as well as being cheaper.

The infrared makes use of the heat signatures emanating from different objects to detect motion. The sensor measures the heat that is given off by an object that passes its monitored area. It then compares it against the background temperature such as a wall.

The disadvantage of this type of sensor is that it cannot cover a large area like a floodlight. It rather works like a flashlight with finger-like points covering center areas. Those that are in between the covered areas are not monitored. Therefore, someone passing through these areas will not be detected.

The system you choose will depend on your house, property and what you are looking to achieve with your system. If you are undecided, get in touch with an expert and ask them to provide you with an assessment. They will look at your property and offer you suggestions as to how you can provide the best possible security. Their suggestions will be based on real world experience as to what does and does not work.
