    Pros: You can easily unmount the parts and with some electronics skills make some mods as a different supply or change the reaction. Cons: Bell circuit could have been separated to reuse for something else

    Good for the money paid, came on time, fairly solid built, easy to put together and REMARKABLY SENSITIVE FOR THE PRICE The instructions are absolutely NON-intelligible, they should just show pictures...For a person without understanding of such equipment, it is impossible to understand how to and...

    a very good equipment especially for places that requires a bit of security. it will catch the attention when somebody goes near this. turning it ON starts the siren which is very loud and takes more than 10 seconds to stop. this should be bypassed as it is not needed to sound because you just it...

    It works. Walk nearby and it blasts away with the siren. Eats batteries. Best to connect a small AC adaptor. The instructions are worth the full price, forget the device.

    Really great product. Very cheap and 100% functional. It has a great sensitivity, neither too low nor too high. You can use it for many purposes, for example to trigger another device or camera. See my Mod This topic below for details. Maybe one, the red LEDs installed are very weak, I suspect or... Read more

    Really worth to the cost. Its just below 8 US$. The Motion Detection is extremely fine. It get few seconds to get the snapshot of the environment and then it is working perfectly. Very Fast shipping. I got it within 1 week (To Sri Lanka) No Sensitivity Adjustment can be done. The manual is in is... Read more
