What is a point-to-point beam?
The detection beam comprises an infrared beam emitter at one end of the beam and a beam receiver / transmitter at the other. The beam invisible infrared beam travels from the emitter to the receiver / transmitter. Q: If the beam is solar powered, how does it work at night? A: The beam emitter and transmitter are each powered by a long life nickel-metal hydride battery pack which is constantly re-charged by the attached solar panel during the day. Q: Can the batteries run low of power? A: It’s very unlikely the batteries could run low of power. Even with the solar panels disconnected the batteries would have sufficient power to work for approximately 2 weeks.
