Other Thoughts:These cameras work great provided that there are no WiFi signals in the area to interfere with the transmission. The images are clear and bright, even in totally dark rooms. The signal suffers whenever the furnace turns on, or if I am using my home WiFi, but otherwise works flawlessly scanning between four cameras (I ordered two more to go with the two that came with the package). The image is brighter and clearer than the wireless camera I was using.
Other Thoughts:I purchased this to add on to my current system. Works great like the others. It is very easy to install. I keep one extra camera on the ready for when we go for overnights or vacations because it is so convenient. We have a few reception problems because of several wireless devices (phone, router), but not too bad. It would be nice if the channel could be changed on the cameras to improve reception - however, hasn't hindered our use of it so far. The picture is still clear enough. The color aspect is not significant...depends on how you use it. We monitor our kids with it. Great product overall. I highly recommend it over a baby monitor any day.
Other Thoughts:The cameras are small, very easy to use, but quality defeats the purpose of even having these running. Bought them to use for outside the house and the range was about far wawy at most from the living room where the reciever was to the cameras outside. Very good product.
Other Thoughts:The 2.4 GHZ frequency range that this unit uses is also used by some cordless phones, wireless routers and other wireless devices. The sound was so filled by clicks and buzzes that nothing could be heard above it. I switched cameras and frequencies with the same result. I also moved the monitor closer to the camera with no improvement. I returned the product the next day. I can only conclude that the interference was caused by other wireless devices in my home or neighborhood.
