Motion Activated Entry Alarm and Doorbell

Pros: Easy to install and operate. Works with batteries, no wires needed. Wall mount included - usefull thing. Swith to mode1 / off / mode2.

Cons: Quite big, but its ok. It plays two different sounds : gong sound and non-recognized chinesse speach, so mostly used bell sound only. This chinesse recorded speech cannot be replaced.

Other: Deffinitly worth that price, especialy when you need it or looking for something like this. Must have for shop owners...

Pros: The entry alarm works very well for it's intended application, it is fairly sensitive straight forward from the sensor and about 3 meters out. It is easy to set up and uses standard batteries. Comes with wall-mounts and screws, all you need to fasten this to something wooden near the door.

Cons: Very narrow sensor field.

Doesn't have a DC power input.

Doesn't have an alarm siren mode.

Other: If you need something to tell you when someone enters a door or an opening, but don't need absolute accuracy, this is great.

Not good at all as an actual alarm where you need it to go off every time someone walks in the sensor field since the field is so narrow.

Pros: -Does not sense move from behind a window, which is good in a store where I bought this. -Build quality is ok. -Price and quality meet each other.

Cons: -Too loud sound -Does not sense move from behind a window or a glass, which is bad if this is used in alarm. -Has a cheap plastic look. -Narrow sense field, which can also be a good thing, depends on a use. -Pretty big, but that does not really bother.

Other: If you need a motion activated alarm, this is your product, and if the loud sound doesn't bother you.
