Description |
| Hang the unit on a door knob and give it a half-minute to "look" at its surroundings. After that, it will sense anyone touching the knob and sound a loud alarm. Very handy while traveling or monitor unwanted door openings. The alarm will operate for days on a nine volt transistor battery. Note that it works best on wood doors with metal knobs (practically any door) but may not perform as well on a metal (steel) door. Battery not included. Order No. PV500. Can ship in 3-5 days. |
