LPRS has provided ITV Technical Services with Easy-Radio wireless modules to monitor the movements of cats for a US-based programme maker.

The programme was commissioned to study the psychology of cats and was made on location at a farm in Scotland.

The filming of wild cats required ‘cat cam’ cameras to be set up and left unattended for many hours.

With only one hour of filming time available on the cameras, a system was required to only turn the cameras on when cats were present.

An infrared beam detector was used at the entrance to a barn that, when triggered by a cat entering the doorway, activated the camera using Easy-Radio modules.

A wireless solution was chosen as the locations of both camera and detector were difficult to access, a great distance apart and running a cable around the barn would have been difficult and caused health and safety issues.

The module used in this project was the ER400TRS-02 transceiver from LPRS.

Low Power Radio Solutions

LPRS Ltd (Low Power Radio Solutions) is a privately owned ISM band
‘easy-Radio’ radio module manufacturer and distributor of Circuit Design,
Prowave and Airwave transmitters, receivers, transceivers and antennas.
Their sales team is based in Witney, Oxfordshire where as their Technical
Centre is in Warrington, Cheshire.

easy-Radio comes in transmitter, receiver and transceiver modules and as a
pendant transmitter. Operating frequency for the modules is either
433-434MHz (ER400 series) or 868-870MHz for Europe and 902-928MHz for USA
(ER900 series). As they’re based on the Chipcon’s RF ICs, the modules also
provide user-programmable features including frequency of operation, power
output and data rate.

The easy-Radio (ER) ERx00TS transmitter, Erx00RS receiver and Erx00TRS
transceiver incorporate ‘easy-Radio’ technology to provide high performance,
simple to use radio devices that can transfer data over a range of up to 250
metres Line Of Sight (LOS). Furthermore ‘easy-Radio’ technology allows
frequency, data rate and power output to be optimised for customer specific
applications. The embedded software reduces design and development time
