One of the other systems is wireless. It utilizes the same alarms as the other systems; however, instead of alerting a monitoring system or relying on neighbors to phone the police department, it contacts a pre-programmed list of people to notify should a burglary occur at your house. There is no risk for false alarm and the responsibility of notifying the police falls upon yourself and your family. It will continue to call the residents until someone is reached at their work or mobile phones. Since nearly everyone has a mobile phone nowadays, the risk of missing the call and letting the burglar get away is low. It is effective; however, it isn't as expensive as the monitored systems with its monthly monitoring fees. Whichever you decide to invest in, it will be sure to reduce the risks associated with home theft. Each has its own perks, so depending on your preference and budget, you can choose the one that best suits the security needs of your and your family.
