does this operate around corners or through walls, or is line-of-sight required for detection?

I have used it in my main floor to find keys upstairs sitting on my bed so it definitely can go through walls, ceilings, etc.

line of sight....I walk from room to room..guess it depends what the walls,floors,ceilings are constructed with.

You can hear it beep within a 20 foot area if not buried under a pillow and dependigng upon the wall construction. Obviously you may have to walk around the house at some point if you don't hear it beep in the area you are in.

It uses radio frequencies (not infrared). Yes, it will go through windows and walls. I can't comment on the range, as the furthest I've used it was about 30'.

No you can't thru wall's , you need to be facing the robosapien in order to use it

I just tried it both around a corner and through a wall and it does indeed work in those situations.

Camera Based Motion detection has always been problematic. the best ones let you set specific areas to monitor (like your desk rather that your whole office, or the gate and doorway rather that the whole back yard, etc). I haven't bought this one yet so I don't know if that feature is offered, but it is pretty standard.

Yes, the signal will go through walls. It does not have to be a line of sight. It needs fresh batteries often to keep it working all the time. I estimate I am putting in new AA batteries once every couple of months. David

Hello DorothyI do not secure the receiver to anything just hide it in a bush or in/under something. You can check the range of the unit to camera on the menu page (little triangle next to view option). I have even put the receiver in a building and it works. No line of sight needed. I have three units so far for remote site security.Hope this helps...

It's an IR remote, so you need a line of sight to the sensor on the camera. No need to be directly in front of the camera, but the sensor has to see the remote. I haven't checked the actual range.

For the most part, yes, it is line of sight only. If there's small objects momentarily in the way, often times the signal will make it around or through it (like a small tree) but for what you're trying to do with it, signal would most certainly be lost. There are, however, ways to make this drone autonomous by adding additional equipment and using software called "Mission Planner 7". for your particular application something like that would be best suited.

No, it is infared, and that means "line of sight" from the transmitter. It would have to be RF[radio frequency] to transmit to another room.

yes, it works through walls and windows. It seems to be a radio signal and works to about 30 feet at my house.I have it plugged into a protected outside outlet and use it from inside the house to operate a fountain pump.

Yes. The instrument has two detection levels, one for low voltage and one for house voltage and above. If you want to check for wires behind walls, switch the instrument to low voltage detection mode. It will then me sensitive enough to detect house voltage in lines behind walls. I've used it to detect wires behind lath and plaster walls which are generally over an inch thick. In high voltage detection mode you have to have the end of the instrument very close to the line, almost touching it, for detection.

You do not need line of Sight.. Works good for what it is... Remote can be better

One additional point. One good thing...There is a status indicator that shows when there is interaction/interference from any source and how much (the more interference the more the status light blinks...where there is none, it stays off)...I actually used it like a homing device to find the right area with the least amount of interference. Without it, I probabably would have pulled my hair out trying to locate the sources of interference.

Will depend on what you have to connect to. You need a point above/below each corner.

it will works through a thin wall if the remote is very close to the sensor

Don't think it will because if the detector is covered it can't see motion.
