I wish to investigate the possibility of an Alarm system for a Driveway - Inductive type seems best to accommodate those needs. (Infer-red or motion detector applications doesn't monitor the ingress & egress traffic flow.)
Criteria: To detect vehicles transporting people and deliveries only. Not lawn mowers, animals, people, blowing trash, rain, snow, fog, or grass fire smoke.
EQUIPMENT REQUIRED:
2 separate Systems (A & B) seem necessary:SYSTEM (A) includes:
1), Magnetic loop sensor capable of being place in PVC pipe 12" below earth surface with 100' underground wiring also put in PVC from sensor to transmitter. 2), Transmitter with a Range of 875', wireless, encased in metal enclosure with metal pole, capable of sending signal with some Line of sight obstructions - Shop building & shrubs. 3), System powered with batteries & backed up by a small solar panel capable of being encased in metal enclosure and mounted on metal pole. 4), Receiver: See Merging of Systems below.SYSTEM (B) includes:
1), [Same as System A-1] (Magnetic loop sensor capable of being place in PVC pipe 12" below earth surface with 100' underground wiring also put in PVC from sensor to transmitter.) 2), [Same as System A-2 except Range of 280' - NO Line of sight obstructions] (Transmitter with a Range of 280', wireless, encased in metal enclosure with metal pole, capable of sending signal with no line-of-sight obstructions.) 3), [Same as System A-3] (System powered with batteries & backed up by a small solar panel capable of being encased in metal enclosure and mounted on metal pole.) 4), Receiver: See Merging of Systems below.Merging of Systems A & B to operate on 3 individual Receivers: (2 locations in Residence) both are to receive signal from Transmitters A & B with two distinct & different sounds "normal volume adjustable" for each system.
(1 location in Shop) to receive signal from Transmitters A & B with two distinct different sounds "loud, adjustable volume" for System A & "normal volume, adjustable" for System B.
Reason for metal incasement requirements of exposed elements was wild animals (rats, raccoons, & others) tend to eat, chew & gnaw on the exposed plastic boxes & pipes.
Had a photo cell system that lasted less than a week after its installation.
