I have found these work pretty reliable, and you can have several sensors on the same base receiver.
I put the extra receivers in the bedroom, the shop and the garage. It has a side effect, the GSD dog usually sleeps outside
and he has tuned in on that beep. He will be totally out of it, but when the beep goes off, he's up and barking!
The only thing, put some electrical tape on the back side of the board, otherwise the batteries can short against the board, dead in a day.
GSD = German sheadder dog, = German shredder dog = German sleeper dog.
