What is the range of the sensor? How far off can sensor detect motion?

If you want a narrower field of detection, there are little plastic shields included. A section of 5 or so, they are perforated so you can just snap off the number of pieces or thickness you want & insert it in the detector to block off part of the motion detector. I never would have known, but I had mine professionally installed and the electrician showed me this feature.

I don't know the exact range but it's very good. I have three of these sensors and one from Lowes. I wish I would have bought four. Well worth the extra money.

It depends on the sensitivity setting and size of object moving as you might expect. That said, I am pleased with my purchase and the effective range that I am utilizing is ~60ft given the restricted area where I have them installed today.

Mine is detecting motion from 35' away from the side of the sensor, which in my case is ideal, while detecting motion from the front of the sensor at about 20' away, again ideal for my situation. It all has to do with the angle with which you set the sensor. You have to play with it a bit, to get the sensor set to the angle that works best for you. Overall, I'm very happy with the light/sensor function and would recommend this fixture!

The sensitivity varies from unit to unit and also is a function of the size of what you are trying to detect. For example, a mouse is unlikely to trigger the sensor at 20 feet away, but a human being probably will. The sensor is motion sensitive and does not, so far as I know, detect infra-red heat. I have three units and their sensitivities vary from about 15 to 20 feet. You will also have to experiment with the aim of the sensors as the angle of view and the directionality of the sensors also seems to vary from unit to unit.

Not very far. The remote can be sensative to other devices and makes noise when there is no movement. We used the sensor by itself because the bell is loud enough to hear in the next room.

It detects pretty far out, I have animals 30' away in a pasture and it will often pick their movement up. I don't know about 200' away, would be better if you could mount it closer to the activity. Also, it doesn't pick up 'wide angle' but only straight out in front of the detector. The 1/2 mile transmit claim is valid though!

We are using the sensor at the front door and do not want everyone on the sidewalk (40 feet away) to turn-on the porch light. We know that when set to minimum it is 20 feet, but we do not know the range of maximum setting.

I am not sure that would work. I think this device uses temperature changes to detect movement. For example, I have this right next to my front door. If I open the door (and it opens into the sensor) nothing happens, as soon as my body is clear from the door then the device detects something. Perhaps something using the contact closure module will be more effective.

Motion sensors are not too sensitive, specially in the case of small pets. Try factory setting first, it should work fine.

I have a motion sensor mounted in my hallway and the receiver in the garage turning on a loud bell(instead of the lights) when I'm away, that's about 25 feet through walls, I'm betting it goes farther.

I'm afraid your Motion Sensor is exactly what it is - senses Motion and even wind... so, it will go off every time a motion is beyond a minimum detectable sensitivity.Best is to buy one, then set it up and see... if it is satisfactory enough, get the second one. If not, use it somewhere else, like checking for racoons/cats/possums going alongside house. It will go off, and scare the animal too. maybe will not come by that way again... hope this helped.

I'm not sure what the specifications say but it is about 60 feet from where I mounted mine to the street and as it was adjusted out of the box, it was seeing cars in the street, so I adjusted the sensitivity and aimed it a little more downward so that it would only detect the closer motion near the door. Works great so far!

Hello, The motion sensor will pick up on a 20ft range, and 120 degree coverage. Thanks! www.FortressSecurityStore.com

Hi ... my light is mounted on a 5' fence to reach up to 45-50' around. I think the maximum motion detection range is about 65', but the higher mounting could increase the distance for motion detection. I suggest you contact the manufacturer for their answer if you need something more precise.

I believe the remote is supposed to have a 75ft range under ideal conditions. In practice, ours (outside, with no walls in the way) seem to have an effective remote range of 40-50ft. The motion detection range, though, may even be better than the 25ft claimed range.

Thats a very good question... The glass is not clear so I'm not sure if the sensor would be able to detect motion at all times.

Detection range side to side is real close to 180deg. It is quite sensitive of my movement even at the end of this range! Also, it does not seem to be activated by tree limbs blowing - amazingly. Distance for detection of a person (for mine at approximately 10 feet high) is about 40-50 feet. I am VERY happy with this item. It lights my entire path from the car to the house and stays on while I am moving. Very easy to adjust to preferences too.

I just tested mine. It picked up the signal about five inches from the iPhone. So not very far away. I was in my kitchen spinning the sensor with my finger.

The sensor is VERY sensitive. I have one mounted under the kitchen counter. I had to use black electrical tape to block about 95% of the sensor, to keep it from activating when getting near the counter. The tile back splash was reflecting my movements from a few feet away.
