Q: can you purchase extra receivers?

dont know its poor quality item

Q: Can it be wired to a door bell?

It would need a DC transformer that has an output voltage same as the unit. Then the unit can be modified to work. If you are capable to do this, then yes. You can even use computer or phone charger ad the power supply if right voltage. It is not hard but you would have to be skilled enough and have the right tools to do it. Just to wire it directly to a doorbell circuit without any modifications, the answer is no don’t do it.

Q: how do i put batteries in?

Should be a small philips head screw on the back cover. Remove screw and open cover. Install batteries as shown.
