Does it require line of sight to activate?

I have a friend who has this model and said he liked it, so I bought one, it worked for a day and then wouldn't. Amazon replaced it, the second one worked very sporadically, and it was very line of sight when it did work. I ended up sending it back and got the Phottix Aion Wireless Timer and Shutter Release Canon it's works great no issues. I find myself using it more because of the convenience of it. That my experience.

Nope! I haven't had the same issue as the other responder. I have two - one for me, one at my workplace. Both work well. Only complaint is the goofy expensive ($10) battery required by the receiver.

from what i know it needs line of sight. it uses Ir. just like a TV you need to point the ir sensor for it to work.

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.

I am assuming that even if there is a light it might not alert properly. I originally purchased the item so that I could have contact between the floors of our house. The intercoms did NOT work and I returned them.

Yes. The Bluetooth remote is much faster and does not require line of sight. I think the picture is higher quality because of the much improved and more modern processor. You may want to try one in the location it is used the most. Some people have complained about the wireless. I use the ethernet connection and that works well.

Yes... Line of sight actually is not required. This is a radio signal that will defract and bounce. It will attenuate some with dense materials, but mainly the low power will limit distance. Mine works over 35 yards or so.

It seems to me that I have to be considerably closer than 20 feet to activate it.

Hi Randy, The unit works on "line of sight". I have one installed about 150 feet from the house and the change of elevation is about 15 feet from the sensor to the receiver in the front of the house. A good rule of thumb is if you can see the sensor from the house, it will probably work. Give it a try...you can always return it... Hey Wally

It doesn't need line of sight to be able to respond, however, it does need to be on the same floor. We live in a three storied house and my wife keys could be anywhere. We have to go to each floor to discover her keys. It has worked well when we needed it.

No, it is activated simply by pulling the pin connected to the unit by the neck pull cord. The only button on the unit is to activate the small flashlight. The other apparent button is a dummy, apparently for design only. The unit works easily and performs as advertised. Also, for in-house use only, consider an electronic doorbell which permits the user to press a button on the remote and trigger the door chime unit up to 200 feet away. Inexpensive units are also available on Amazon.

Don't know about wink but found out they do not operate more than about 30 ft from your control panel. We had two outside buildings about 100 ft from the panel and they will not activate.

Line of sight is not needed. I have the power strip located on my desk behind my monitors and the switch for it, mounted under my desk. Works great!

You need to get RF universal remote which don't require direct line of sight. Logitech ones are great.

The system works with radio frecuency, line of sight is not necessary but concrete, brick or other very dense wall materials do limit its wireless range. The system has a range of well over 150ft. In line of sight conditions.

No it does not, but it does not need a line of site either...works from a good distance without line of site though...overall a good product too.

Hi Dana - the remote will only work with line of sight. In other words you have to point the remote at the pickup sensor on the front of the camera (or on the back if your camera has a rear sensor).

Yes it's using a wireless frequency and not infrared which requires line of sight. You will be a will to change the channel from outside or on a different floor. The product works pretty well, and I would definitely by again if mine broke. The only issue I have had is getting the blaster to stay in front of the cable box. I rigged it with tape
