Detecting when sensor lights turn on
Does anyone have any brilliant ideas about how a security guard can be
notified when sensor lights turn on? The lights may be up to a mile away so he can't necessarily see when they turn on. The guard will be walking around, so there will have to be notification via radio or cellphone or pager etc. Ideally it would be helpful for him to know which lights went on. When notified, he can go somewhere to look at a screen. Or he could have a laptop computer using WiFi that can show whatever he needs to see. I was thinking that each sensor light could have a signal wire from the supply to the bulb or from the relay, to a central point. Complications are that he may set off sensor lights as he is walking around, and cats etc may set them off. So, lots of false negatives which he must be able to discount. |
