The difference between tripwires and beams.
Beams are sensors that are mounted to the walls and show a red light when they are activated. If you are in an area with beams you will see the light turn on and know that you have been picked up by the alarm. This form of security is not obsolete, however, tripwires are a better deterrent. Beams are visible and can be stolen, bypassed or tampered with allowing perpetrators to enter your property or bypass the alarm remaining undetected. Beams will pick up the motion of anything that passes by the sensor and can result in false alarms if your pets or any other animal passes through that area.
Tripwires are lines of access that are marked out on the CCTV camera from the control room. These lines, unlike beams, are not seen outside of the control room giving your property the best form of protection against perpetrators. Tripwires are “drawn” onto the cameras and can be changed at any time. Line Crossing detects a moving object which crosses the defined line. Entry/exit direction can be defined and the line can be drawn in any direction and work day and night. Tripwires are integrated into the camera thus allowing the operator to determine if the threat is positive – being an intruder, or negative – being a pet or any other animal.
WATCH: Alarm triggered by an intruder.
