can I use it in a trailer with a battery? Does it only have a shock sensor, or can it sense a door being opened?

You have to have a sensor and know how it works with power and ground, but it will sense a door opening too.

It can be hooked up to a trailer yes. If your door isnt automatic or have some kind of power source. The door sensors wont work for you.

Yes! I have mine set up at an entry door to my house. I get an alert within seconds of motion. Then I can use the app to view the video. At any time you can use the app and see what the camera sees. It's a great investment for peace of mind.

No. This locks the door from inside . Door opens in and basic use for when u sleep.. or just. Extra safety. I think you would bee better off with a door alarm and or motion alarm.. siren is loud and some will call your cell if activated. Good luck chris

I've not replaced the battery after about five weeks now. It's not sensitive enough to trigger when trucks rumble by in my parking structure, but will go off if I lift it about half an inch and drop it. IOW, it works for me.

It has an audible door bell. It will operate on batteries or you can tie it in with your current door bell.

I don't think so. It works on gravity and moves on a straight plane. Your door moves on an arc. You might consider the door or window type alarm, or even the motion detector HA434TL 3 1/2 h x 2 1/2 wide x 2 depth..It could sit inside in the back, and detect motion when the door was opened.

Can you explain your process a little more detailed? I'm not sure I follow you on the means of a door sensor.

If you haven't check your remote battery I would dcheck that. Evn though before I replaced the mechanism I could hear a little sound in the door. After I bought this unit and installed it, the locks worked and are still working great. I had to replace both sides. THe keyless entry all worked on the first attemptThis saved me more than $500.

I hooked two of them up, one inside our soffits hidden from view above both outside doors so they can be used as a panic alarm to drive off intruders, they are switch activated, I have them hooked up to a small 12 volt dc battery back up system so they will work even when the power is out. So yes, they are safe to hook up to a 12 volt battery with a switch.

I hooked mine up to a transformer and did not use a battery. If you have voltage at the power connections and it does not work I would think you have a bad sensor.

No. It has the shock sensor and that's it. I need one of those as a matter of fact.

Hi Dave, Outdoor motion sensors are usually workable cheap single or chained units used for driveways or sidewalks etc. They beep once when a car or person etc walk by. To the best of my knowledge no one builds one that trips a dry contact alarm or horn etc., so when they go off and you are asleep forget it. However is you have a home alarm system you could place a motion sensor outside under the eves for example and the control panel should pick it up just fine. Some panels allow you to set zones etc. which can be used when asleep to alert you of unwanted activity etc.

it has a small battery in it. you have to open the door and remove the pull tape from it so the battery becomes active.

I put batteries in mine 3 months ago. I've only pulled my trailer 3,000 miles, that's about 60 hours. Batteries are still working fine. Keep in mind that the monitor has auto shut-off if it doesn't feel vibrations of the road, I've had mine shut down while stuck in traffic jams. The unit also comes with a cigarette lighter plug.

The last time I researched the dual alarms were not available in battery operation. They are only made to be hard wired because the dual capability needs more power than batteries can provide. The battery operated ones that I bought are VERY sensitive and work VERY well on all 3 floors of our home.
