A home burglar alarm system ranges from an expensive, professionally installed burglar alarm system to a low cost do-it-yourself (DIY) home security, which can be installed for $200 or less.
The most common do-it-yourself option is hard-wired system. As the name suggests, the alarm is connected directly to an electrical power circuit. These alarm systems can also include sensors such as magnetic switches and motion or smoke detectors to safeguard the home from other threats like fire.
Another do-it-yourself option is wireless alarm system. It uses radio waves and requires no great skills to install. Supervised alarm systems are those wireless systems, which can monitor their sensors to ensure that they are communicating properly with the control panel. Some of these supervised systems are inexpensive and can be connected to full-time monitoring stations installed in a security company.
Another do-it-yourself option is the self-contained burglar alarm system. It can be plugged into any outlet and can be removed as and when needed. These systems can be bought for $150 or even less.
The following points must be kept in mind while installing the DIY burglar alarm system: - The signal strength and background noise levels in the proposed location should be checked before the devices are mounted;
- The transmitting and receiving devices should not be mounted under metal lintels placed on top of windows, doors etc. because they affect transmission of signals;
- Any wiring into the transmitters and receivers should be kept away from the aerials.
- Receivers or receiver aerials should not be mounted near to electrical distribution equipment, televisions, computer equipments or large metals.
- Make sure that the remote aerial is mounted in the correct orientation. Never clip any other cable close to the aerial or the aerial cable. Also, try not to run your aerial cable next to mains cables.
- In case of very thick walls where the signal strength is weak, the receiver or its aerial should be mounted high up in the loft.
- Survey the premises carefully before installing the detection devices.
