Will passing trucks set this alarm off?

Yes, it happens. Depending on how you adjust it, any event that shakes the device will make it sound. Good thing is it stops by itself, as soon as the shaking ends. It isn't the kind of alarm that sets off and goes on and on. It is a very simple mechanism that works exactly like an electronically amplified church bell. As soon as the little metal hammer stops touching the side walls, the sound stops.You can turn sensitivity down, but that could make you miss smaller vibrations from real quakes.

No. You can actually set the sensitivity of the alarm to make it only response to big shake.

I live in a concrete house with no nearby road so I wouldn't know. You CAN set the sensitivity for the alarm but then of course if you adjust it to a low sensitivity, it will only get triggered by 5.0 quakes and larger for example. I can tell you that I have mine at a high sensitivity and lightning does not set it off.

no the alarm sensor will allow us 8 seconds after we push the bypass, after that it will sense the door is open and go off. When we have parties I usually remove the battery, due to the reason we are outside all day, and it allows my guest to come in and out of the house.. :) Hope this helps

not really. just an alarm that can let you know if someone break into your car if your within the distance of the paging.

Yes there is an alarm sound, but you can turn it down or off. The speed Indication also changes to red when you go over the speed limit.

I leave mine on all the time and it draws less amperage than an alarm-no moving parts whatsoever. You can set it to shut down after the vehicle is stopped too. I bought another one for my other car too.

This alarm does not sound like a car alarm. It is a very loud whirling alarm. It will definitely be noticed by anyone in the vicinity and a distress call.

Your system was installed incorrectly. This system is not an alarm, and the vehicles alarm system is what's being triggered. The only way to turn it off is by using your key to unlock the door of the car.

Haven't noticed more false alarms due to weather. Mine is mounted on a fencepost, and so far snow has not been deep enough to cover it. Most false alarms have been responses to large trucks that are on the road just beyond the range that is supposed to be the limit of the sensor.

I believe so. We have it mounted on a jail transport van, and it is loud enough to warn pedestrians, but not so loud to wake up the neighborhood at night.

A thief can, if they are thinking clearly, after the alarms gives them an earful. If not, like most, they'll likely take off running. Or maybe they'll just burn the place down which no alarm can prevent. For the money this is a nice product. Though I am only using as a door chime.

I don't think so. At first I thought it was really cool and working but now I noticed it goes off AFTER I've gotten up. so I will have already gotten early and done a few things and then the alarm starts.

No it won't unless you've walked 30 ft away from your keys then the zomm alarm goes off but your way too far by that time to notice

NO. Also keep in mind, fence gates are not a tight fit. Not only that, on a breezy day... your alarm will be going off every 2 seconds! You would be better off with a motion detector facing an area of none movement that would intercept any movement. Hope this helps.

I beleive there is a delay and it will only alert if there's motion from my experience. I'm not using it right now because of too much traffic so I can't be too specific. So intentionally no.

No - install on the wall and when turned on with fob it's alarm is motion activated.We used it to alert us when dad was getting out of bed. He had Alzheimer's.

No any current change in the vehicle will trigger it to sound the alarm anywhere u have a light switch related as to a dome light.
