    works, but it would look better if both cables are in one.

    It works fine. It sends signal just when the sensors are detached, as it was expected. The alarm is triggered when the gap is bigger than 1 cm. The unit is very small, just one and half cm long, so it is almost invisible above the door. Great product for this price.

    Works exactly as advertized. It'll trigger with about an inch of separation, although at that distance I wouldn't expect it to be perfectly reliable. Naturally, the closer the magnet, the better the reliability.

    Przewodowy kontaktron współpracuje z centralką gsm. Elementy posiadają taśmę samoprzylepną, dzięki czemu mocowanie za pomocą załączonych śrubek staje się zbyteczne.

    Ultra small magnetic switch in white plastic casing. Easy to hide. Would be nice if wires where longer.
