There are benefits and detriments to both hard wired and wireless burglar alarm systems. Careful consumers will check around to see what type of alarm system will best fit their needs to provide adequate protection.
1 / 5
Hard wired burglar alarm systems are wired from the master control panel to each security device. This calls for drilling through walls to each device. Wireless burglar alarm systems rely on radio waves sent from each security device to a master control panel. No drilling is needed.
2 / 5
Hard wired burglar alarm systems should be installed by a certified technician. It is best to find out how long the installation will take. Wireless alarm systems can be installed either by a technician or the end user. These installations require less time than hard wired systems.
3 / 5
Hard wired alarm systems normally require little maintenance since the only battery generally used is in the master control panel as a backup for the entire system. Wireless systems require separate batteries for each security device. Batteries have to be replaced from time-to-time.
4 / 5
Hard wired alarm systems are usually hooked up over existing phone lines to a central station. Line seizure should be used in case phone lines are compromised. Wireless alarm systems are sometimes incapable of sending signals to a central station. Subsequently, only a bell or siren will sound if a break-in occurs, resulting in only local notification.
5 / 5
Hard wired alarm systems are usually left in a home when residents move. This can be a selling point for the home. Wireless alarm systems can be taken when moving. Make sure the system will provide adequate protection for the new residence.
