Recommendations For Proper Protection (contd)
Recommendations For Proper Intrusion Protection
For proper intrusion coverage, sensors should be located at every
possible point of entry to a home or commercial premises. This would
include any skylights that may be present, and the upper windows in
a multi-level building.
In addition, we recommend that radio backup be used in a security
system so that alarm signals can still be sent to the alarm monitoring
station in the event that the telephone lines are out of order (alarm
signals are normally sent over the phone lines, if connected to an
alarm monitoring station).
