Automated sentries

[Timelord]

Shed wireless PIR systems are a very useful item to have. You can get extra PIR's to go on the system. The batteries that I have seen are usually AA's, so are ideal for solar charging.

These systems are lightweight and can be set up anywhere, buildings, outdoors, temporary camps, day or night.

For outdoors, the unit may need weatherproofing.

The sounder can either be muffled to be more covert or can be set up remotely to act as a distraction whilst at the same time alerting you to a foreign presence.

The sounder can be modified to operate an alternative electrical trigger circuit of ones own utilitarian desire.
