I am thinking of buying this product to keep an eye on my elderly Grandmother who lives next door (approx 150 feet) and am wondering about the range.

dunno about the range. I bought it to use for a visual when hooking up my camper. I took good care of it and kept it in the house except when camping. It quit when I went to use it on the third trip.

It works great bought mine for my daughter who has 4 wonderful but mischievous sons. Older ones haven't caught on why Mom knows what is going on.

The range is very poor I bought mine to get an eye on my 2 month old son while I washed his bottles and cloths and only a wall would separate us and there where range problems.

I have it inside my house, about 16 ft away from front wall, and I have connected outside the house, across the street about 50 ft away. Don't know actual range, but it's pretty good for my needs.

I don't know the range, our farthest unit is about 200 feet from the receiver. It does not interfere with. nor is interfered by cable television or Internet. I have found it to be a very good product.

I think the effective range is about 150 feet in a residential environment.

I have used it from approximately 90ft away without issue. You should be fine from 50 or 60ft.

The range is reasonably large but no more than necessary to get to bike quickly enough when alarm is triggered. It is claimed up to 700 meters in unobstructed view, though actually I do not go away farther than one or two minutes from reaching the bike, and experienced no problem. Frankly speaking, nobody tried yet to touch the lock during three years (except for children who get amused its loud sound, and even play hide-and-seek with the owner), looks like it's an excellent visual deterrent compared to various cable locks. As for false alarms (because of wind, or careless passerby) the farthest range proved to be operational was on the fifth floor of a building, on its backside, and the distance to the bike protected was about one hundred meters on the ground level. So 100 meters plus a couple of bearing walls plus height of 20 m is not a problem for it.

I've successfully used it up to 50 feet away, but don't know what the longest possible range is. You do not have to be in line of sight -- it will transmit through doors and walls, though the range is reduced.

I've got good control at about 150 feet. It starts to loose the connection that far away (or up). It's about as far as you can go and still easily see which direction it is pointing with subtle movements.

The range is well above 1600 ft. In fact your neighbors will be in range if you don't use your security included with router, they'll be able to piggy back on your signal.

I have used mine up to 150 ft with no problem, I would highly recommend that you get the laser detector to go with it though. It gets hard to see the laser the farther you get but with the laser detector it is easy!

I have tested the range, and it works very well at long-distance. I can't ever see it not work, because by that time I'm too far away to see the screen. I'd say the range max is probably 35 feet.

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.

It has good range, but I don't know about 300'. Maybe under absolute perfect conditions. It's a very good product though. I've had family tell me my voice is noticeably clearer when I use it than when I don't. As with any Bluetooth signal though, close proximity to a running microwave will dramatically affect the reception.

In general, I agree with Mike about the range (25-30 feet), but I found that walls in the house can interfere and shorten that range. I really like this device and have been using it for over a year now to watch videos while exercising. No problems at about 10 feet. I don't know the frequency but haven't noticed any interference issues with cordless phones or wifi.

Line of sight seems to help this device. Some seem to have varied results. I'd say I can go 50' or so without breakup. As it gets out of range it continues to broadcast but with interruption and disruption. It's a great device.

I bought these for my 99 year old father and they work well for him. They will not detect motion from 15 feet away. My suggestion is that you put three of them in a 30 foot hallway.

About a 100 feet. Ours is used for ghost hunting. It can be placed in an upstairs room and still be 100 feet away
