Alarm: Intrusion Detection Systems

The selection of a alarm system is not a simple matter, because the needs of each home-owner or businessperson are different, like a set of fingerprints. Some factors that determine requirements of an individual alarm system and questions that must be answered when selecting a system include

• The threat or risk – what is the system to protect against ?
• The type of sensors needed – what will be protected?
• What methods are available the level of protection needed.
• The method of alarm signal transmission – how is the signal to be sent and who will respond?
