Job Description

Wireless Monitoring System
This job is being re-posted. Please DO NOT REPLY unless you can provide the requested project outcome and all deliverables. PLEASE DO NOT provide quotes that are incomplete or require additional work to be operational.

The wireless monitoring system enables on/off switches to be monitored via a remote radio link and will replicate that state of the transmitter input switches on the receiver outputs. Transmission range should be at least 500 metres line-of-sight (250 metres in an urban environment), with various antenna options available for increasing transmission range.

The system will consist of a transmitter that can send four (4) independent on/off channels simultaneously to the corresponding receiver. Each input channel will be capable of sensing the state of a dedicated switch (either on or off).

The transmitter/receiver pair should be uniquely addressable so that multiple systems can operate in close proximity to each other and not be susceptible to interference or crosstalk of any kind.
