Does the door sensor use a widely available battery (for example AA, AAA, 9V) or something odd?
Our office has a lot of people continuously walking by the front door where we want the door chime. Will the chime keep going off every time someone walks by that is NOT even entering the office and just passing through the receptionist area?
Can you please tell me the decible level of your product? Thank you
will the door alert sensor work on metal door and frames?
