security alarm systems for homes
These burglaries cost homeowners some $3. 1 billion with the average loss per burglary at around $1,700. For most homeowners, the
presence of a home alarm system is enough to deter burglars but when it is not, it serves an additional function. As well as signaling authorities that the home has been burgled and increasing the chances that intruders
will be caught, the cameras installed with many modern alarm systems catch the intruders in the act. Having visual documentation of the home intrusion increases the likelihood that the burglar will be identified for the crime committed. Video footage also helps homeowners create a record of what has been taken from their home during a burglary.
