Help designing a sytem to alert the cashier about someone

[313-313 0]

I have this customer that has a server problem of people from the nighbourhood using his convenience store garbage dumpster. He wants me to design a sytsem where by the cashier can be made of, when someone come by the dumpster to throw trash. So that the owner can get the video and catch him at the very same time. he is using a GV800 16 channel pc system. Need some innovative idea regarding this system.

Put a camera on it and have motion detection trip a relay that makes a buzzer go off at the counter.

CollinR. Can you please elobrate with detail. I heven't used any kind of relay with a buzzer ever. Again this is a Gv system. Hence I guess i will need a IO Net card. How do I install the buzzer, relay I mean a wiring diagram...

you will probably get a bunch of false alarms. I would suggest getting the optex outdooor motion detector with voice program. You can have it both alert the cashier plus tell them any customize voice warning you want. They work excelllent and not expensive at all.

Get a doorbell from your local hardware store, put the relay from the GV IO where the doorbell's button would normally go. You should be able to use the doorbell's wiring diagram. If you get a nice one you can have 2 bells 1 for the entry door and the other for the dumpster, just make sure it has a tone difference for the two. This might go beyound your wiring experience though as you will either need another relay NO from the front door or run it through Geo as well.

 

Set the camera so that the dumpster takes up most of the FOV. Use the advanced motion detection to seperate the remainder of the FOV from the dumpster itself. Set your 2 MD sensitivities so that outside the dumpster just gets recorded but you have to raise the lid or throw a large object into the MD zone covering the top of the dumpster to trip the alarm. Obviously you want the camera up high to give the best perspective of the dumpster lid.

 

Use a seperate high quality camera to actually identify who is doing it if the guy wants that captured, one camera most likely can't do both well.

 

This assumes that the guy doesn't care if his customer comes in a buys a pack of smokes and then ditches the wrapper in his dumpster while walking offsite. A normal PIR or PIR/Microwave motion would false on that whereas you can use that zone's sensitivity to control pretty precisely how large the object going in the dumpster needs to be to trip the audiable alarm. This way even a light bag full of trash thrown from a distance will still trip it. This also assumes the dumpster is exposed, my banking customers have their dumpsters enclosed and as such you could just put a $2 magnet contact on it's access doors.
