What is the range of the motion sensor? Any motion will be approximately 20' away as they will be tree mounted.

Depending on the angle, I have gotten mine to turn on as far as 30' away. Had a problem with one light not turning off, other two are fine though.

comfy... re: range of motion... at 20' and at the most, 30', my sensors still work. I believe that if you use the best batteries you can find.. you should not have a problem.

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.

I dont know the exact range but my lights will detect motion at least 20 feet away

A couple of ours are tree-mounted; both work beautifully at ranges slightly exceeding 20 feet. We DID have to adjust one of them more downward than the other to accommodate our circular driveway, but it was an easy fix. These are the brightest Mr. Beams we have installed to date. Even came back for more.

Mine is about 25 feet away and is completely reliable. The manufacturer claims it works up to 150 feet.

I get about 150' out of mine. Much has to do with the battery, objects between you and your vehicle, where you placed your receiver. I use mine on my sons quad while its on the trailer. The remote will sound several hundred feet away and through glass when you set the alarm off.

I purchased several motion sensors, and some are able to detect motion at 20 feet and others are only able to detect it at 12 feet (even if I adjust the sensitivity). I also found some units to be more prone to activating false alarms than others. This all points to poor quality control and testing with their production, but most of units have proven to be very good and continue to perform well after 18 months of use.

I have them mounted on trees about 7 feet off the ground. Cars, deer and small animals on my driveway set them off but not bugs or blowing leaves. The stated range and angles of view are about right.

The motion detector always activates at 30 feet but sometimes at 50 feet. Intervening branches probably interfere. I'm very happy with picture quality, battery life, and with this camera overall.

Keep in mind the range for the motion sensor to operate is approx 40'. Also there is a visible red flash, while not very bright, may invite a vandals attention.

I would not place a motion sensor 300 yards away from the mailbox to alert you when someone is delivering mail to your box. At 300 yards, the sensor will pick up a lot of other movements - birds, etc... Best to put (screw/tape it down) the sensor inside the mail box. It has been three months, and the batteries in my units are still working good. You question is probably whether the receiver can receive signals from a sensor that is 300 yards away. You will never know until you try it - every situation is a bit different. The signal can be easily blocked by multiple walls, etc... I have tried up to 100' (size of yard) and it still works - 300 yards is very, very long way away.

I have mine mounted on my House overlooking my Back Deck . My deck is about 16 ft. in Depth and it detects movement at about 12 ft .

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

I set the sensor at number "7" and it sprayed approximately 32 feet. The distance depends on whether or not your terrain is level and if you have it pointed up or down. My terrain is level and I have my unit as level as possible.

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.

The instructions say approximately 100 meters (so 328 feet). Ours is just over 100 feet away.

Not able to really answer as I have not tried any of these out side.....I am a little skeptical of using them outside since I have a lot of trees and the constant movement and on/off I think would be too much for the unit in my yard.....might be a different story where you did not have anything but an occasional movement at night.....

From my experience, any things is moving in front of the sensor about 45 degree and up to 10 feet will work. Make sure you set up the bulb with object moving in front of sensor (the tip for the bulb)

I didn't experiment too much to figure that out, but I do know at least 20 feet. That's how far the driveway is from when get to the corner of the house and it turns on. The sensor can be swiveled as well to the angle you want it to work the most.

This sensor could be mounted at 8', but do not expect the same performance as if mounted at 20 or 30'. The detection range will be smaller than the specified mounting heights. Use the lens that is designed for the lowest mounting height. Depending on your application needs, you may want to use a standard sensor for better detection.
