Driveway sensor

[beowulf]

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.

I installed this one about 4-5 years ago. It has worked flawlessly. Wireless. It is about 700-800 feet as the crow flies from the sensor at the gate to the beeper in the house. Detects motion passing in front of it and is adjustable for sensitivity and distance. If this one ever clonks out I will order the very same one. This detector, plus our mean dog sign (our pitbull has rabies) and the armed response sign has done the job. Also nice to know when packages are dropped off at the gate, or when guests arrive (when we expect guests we unlock the gate).

How long do your batteries last in the outdoor unit, we have had one for a year now and seems to eat batteries. We have had great luck with few false alerts. Fixing to do a gate with electric opener so may upgrade to a different system.

After years of frustration dealing with a Dakota wireless system I replaced it with a DA500 - Mier Wired Drive Alert Kit & have been happy that I did.

I can only recall changing the batteries twice, I really can't recall a third time, which now that I think about it is remarkable. Also, I did smear a bit of silicone caulk around the lip to prevent moisture from affecting it - something I do with a lot of outdoor things. I cannot explain why you would be going through so many batteries. Maybe you have a lot of traffic which somehow takes up power to send the signal. We have very few hits - we are both retired and don't head to town but about once a week, and only rarely get other hits, e.g., a UPS delivery, an occasional wild pig. Using up batteries has never been an issue.

My Dakota Alert transmitters run on 12vdc, meaning a 4 x CR123 battery pack. On the one at the solar gate, I just alligator clip 12vdc from the gate battery to the transmitter battery pack terminals, so no problem there - it has an automotive 12v battery with solar charging via the gate control panel.

I was replacing the CR123s on the other one about twice a year. Maybe 6-8 "events" per day. Got annoyed with that, so built a little outdoor electrical enclosure box filled with a gel cell battery and solar controller and mounted a 20w solar panel on the cover. Got about 2 years of trouble and maintenance-free use out of that so far.

Ok thanks, it may very well be the number of hits it gets, we are in and out multiple times a day and right now we have to get out to open and close the gate making the sensor go off several times just for one entry or exit.

The magnetic probe sensors run on 12v.....the motion sensors on 9v (6 AA batteries).
