Driveway sensor

That's what I have. Lots of false alarms.

Interesting. We had a few initially but then adjusted the settings. I suppose we may get some - but I would think not more than one a month and I sometimes just think it may be the wild pigs but don't know for sure since it is too far to see well at the gate. We do have it outside the gate so cattle won't trigger it. And I guess it is also possible it could go off in error when we are not in the house to hear it. Anyway, we have been very happy with it.

, plus our mean dog sign (our pitbull has rabies) and the armed response sign has done the job. ]

Ya, I am sure the works. I am guessing you are joking. I would put friendly sign of dog. We love our___.

I am still trying to figure out, if you guys sit in your den, playing master mind criminal with monitors, or our idea of safety is different. Atlanta and CA.

I purchased the HF Wireless Security Alert System a while back with a $10 coupon just to alert me when critters are tearing up my back yard. So far every time it has gone off a critter was responsible. Has never sent a false alarm from blowing wind or leaves falling. Says it has a 400ft range but I don't have it at that distance. The sensor is in the back yard and the receiver is in my front bedroom though.

My property is gated so I no longer receive uninvited guests.

With motion sensors on these systems, I'd guess they have a sensitivity setting but you can also mask the lens where it scans the ground, the ones that angle down. Many infrared detectors have 3 tiers on the lens stacked vertically. Mask the bottom row and see if that decreases false alarms.

I mask the lens from the inside of the detector with electrical tape.

You can probably mask the 2 lower tiers and still have the detector trip with a person walking through the field of view.

This is the one I have - set it out to about 300 feet from the receiver. Notice it has a blinder over the detector to prevent false positives. I use it to monitor my driveway after it splits off from the shared portion.

We've had an air hose type connected to a transmitter about 600' from the house for so long here that I cannot find the records on it. Works very well. We've a baby alarm sitting beside the receiver in the house. Can place the receiver to the baby alarm anywhere, even carry it with you, if you put a 9 volt battery in it. The 9 volt battery in the transmitter on the end of the air hose across the driveway needs replacing about once/yr.

This, combined with a solar powered gate, works quite well for security.

Tried a sensor type first. Think it was infared. Gave a lot of false alarms.

Correct about joking re the pitt bull. But do have a sign with a doberman pic that says"If it comes into our yard we get to eat it." The reality is that our two rescue dogs are the best dogs ever but useless as an actual deterrent.

Dakota MURS with magnetic probe. Been in place for years with no problems at all. Wired up to small battery and solar panel so I don't have to do a thing with it.

That's a low cost thing. I looked up some after my wildlife camera showed hooved rats getting inside my electric fence, and they were up around $100.

Harbour Freight has a store in Waynesboro, Va. Saw it Sunday on way from church. Open Sunday 9-6. May stop in and look around.
