Motion-Sensing Door Chimes
A chime announces when someone passes through the infrared light beam and a counter keeps track of each entrance and exit. Mount the transmitter and beam reflector between 2 and 20 feet apart. The chime's volume is adjustable up to 85 dB. It cannot be sold to California due to local energy efficiency regulations.
Additional chimes (sold separately) can be added to the transmitter.

Vehicle Alert Bells
Just like the bells you hear at service stations, these bells ring when a vehicle drives over the attached hose.
Add extra hose to span up to 300 ft. Use a hose splicer to connect hose lengths. Use a hose anchor to secure the end of the hose.
