Keith Annabell commented about 1 month ago. Good morning.
You say the transmitter is self-powered. How? Does it have an internal, solar-charged battery, or what? How waterproof is the transmitter? Can it be fastened onto an outside gate? Six batteries, so presumably 3 for each receiver? Can it still be used with just one receiver, or does it need both to work? What would be the average life span of the batteries, with very little useage?
Cheers
