Low-cost Gateway Alarm
With the same detection range as our FarmGuard sensors but slightly less transmission range (300m between sensor and receiver), this represents an economical alternative. The system comprises a PIR infra-red sensor with a 35m "beam" and a small plug-in receiver / buzzer. This receiver is suitable for use as a "chime" to alert you to the arrival of visitors, deliveries etc. It's unlikely to wake a sound sleeper. For night-time security applications we suggest the much louder Rx1 receiver. This is about the same volume as a domestic smoke alarm, and has a socket for the connection of an external siren.
