what is the range of underdoor space that this device will work

Not much. If you have a threshold or a carpet I don't think it will work. My door was too high due to the threshold so it wouldn't work.

The installation will be a bit tight, but it should work. I had no issue with my installation as the space behind it was adequate.

I mounted it 8 inches above the door of the building so that the building eave doesn't impede the sunshine for re-charging. It activates at 3-4 feet away from the door.

The ones I installed required a gap of < 1/2 inch to function correctly. The smaller magnetic portion has some flexibility for mounting with different height bases. You might be able to get creative and make it work.. I have had to mix up how I mount them.. on some doors I mounted the larger module on the trim and some on the door surface. It's hard to know for sure it will work until you try. Also, because this sensor has a remote sensor header you could put something like a rolling plunger switch inside the door frame and run a thin wire (I used leftover cat5) between the two.

I have my router setup about 50 feet from the doorbot and it seems to work well. I think it probably depends on the router but if you can connect to wifi with your mobile phone from where you are planning to mount it then I think you would be in good shape.

I have no problem with mine will open door about 10ft away. Have an external antenna because I have a steel building.

I have not had very good luck with the range or the sensitivty of this device. I bought two of them and one does seem to have a little better sensitivity then the other but neither are great. For the price, I have simply installed them at about seven feet high and point them in the direction that I want covered. I hope that just the site of them is a deterent to an intruder. Mine are installed outside of my house but they may work better installed inside.

I would think not, more than a couple of hundred feet ought to be the limit. I think the published max is 330 feet. the keys work because the system cannot see them when you leave, so they know you are out of the house.

Well my equipment is behind two walls and it works great. You just have to make sure the sensors are in the right spot.

Hi Joseph,The range is better then 5' maybe 15 or so but if there is motion in the room between or behind the sending device it breaks the signal.

I have used it at over a total of 50' and partly outside the building. DECT is a fairly good standard and I used is years ago for a local telephone network in Poland, so it is robust for a low powered unit. Of course it depends on metal enclosures etc. Screens can cause blockage as can metal doors.

The crawl space vent opening is pretty small, I guess the answer is if you are thin enough to fit now, you will, but my guess is a no! you will need a different way to get under your home so may be talk to some builders.

No more than 30 feet. Less if there are walls in between. Works as well as other BT devices I have.

It depends on the ceiling construction, but the range is pretty good. I have two of these in an old plaster house and the receiver unit is completely above the plaster ceiling and they both work anywhere within the room, and anywhere in the adjacent room that is within line of site of the doorway. They do not reliably function through a plaster wall.

The alarms are loud enough to hear even behind a closed door. I have my furthest around 15 feet, it will all depend upon the amount of other wireless devices you have running as to whether or not it will interfere with the signal.

With no obstructions, about 30- 40ft. Make sure you have the transmitter and door magnet sensor touching each other.

I wouldn't know. I returned the item. I couldn't even get my dog to use the door period for the reasons I have described. No one, not even the intended user got through. RFID range is close to zero.
