News Story – LaserShield Home Security System

A wireless portable alarm system has a few benefits:

• It is a handy security measure if you are travelling, and feel that you will need the additional security of an alarm system where you will be staying.
• If you rent a house or a flat, your landlord may not allow you install a wired security system, as this would require you to drill holes and run wiring through their property. Also, when your rental tenancy expires, it will be easy to remove the portable alarm system and take it with you.
• Being wireless, these portable alarm system products are quite simple for anybody to set up and install.

There are a few good wireless portable alarm systems to choose from, such as the Laser Shield Home Alarm System . A base unit and one or more motion detection units are normally included when you purchase a wireless portable alarm system. The alarm siren is built into the base unit. A motion detection unit normally uses a passive infrared (PIR) sensor to detect the amount of the infrared energy (or heat) within a room. An intruder in a room will give off body heat – this body heat will increase the infrared heat level within the room, which will set off the alarm.

The base unit of a portable alarm system may also include an auto-dialer. An auto-dialer connects to a standard telephone line, and dials a specific telephone number when the alarm is triggered. The telephone number of the local police, a security monitoring company, a friend, or a family member may be programmed into the device. The device will then play back a pre-recorded message to this programmed telephone number.

The things to check out for when buying a portable alarm system are:

• What wireless range does it have? What is the maximum distance that you can you place the motion detection sensor from the master base unit.
• Is a battery backup available for the system? The system should still be able to function in the event of a power failure. The system should work off mains electricity with a battery backup, or work off batteries alone.
• Is the portable alarm system expandable? A wireless portable alarm system should allow you to expand and include additional motion sensor units – some allow you to include other types of sensors (e.g. door/window sensors).

Another alternative to purchasing a wireless portable alarm system is to purchase a standalone wireless motion sensor alarm. These devices normally combine the motion detection sensor and the alarm unit into a single device. These standalone devices normally run off batteries, and can be purchased quite cheaply.
