Uniden G2740

Will not recommend, brought the 4 camera system, the battery on the monitor has died, and Uniden will not supply replacement, have to send unit to Sydney at my own cost for technician to have a look at it and give me a quote, minimum $85 bucks, and could be more, during the time using it, found it very unreliable, had to turn cameras on and off to get a pic, sometimes.

I have this system with four external cameras. The two cameras mounted the greatest distance from the monitor have operated with the least problems. The other two cameras, which are mounted much closer to the monitor, constantly lose signal requiring their power supply to be turned off / on again to regain signal. My next door neighbour has the same system and is experiencing the same problems. Neither of us would recommend this (nor any other Uniden) product to anyone based on our experience and the lack of support offered to address these issues.

This system needs to be plugged into the 240 volt mains all the time as the tiny battery in the receiver /monitor doesn't last long at all.
Eventually the receiver/monitor died rendering the whole system useless. I think it may have been the battery but I am not sure.
While it was working it was an average system for security as the motion detection on high records almost constantly and on low can miss a person walking in front of the camera. A variable dial or maybe at least a medium setting would have been useful.

I have been using and putting up with this camera system for a few years.
When you try to connect via the app it is hit and miss some times it will connect and other times it wont.
The cameras are not that far away from the base station and still I have trouble gaining a stable connection when I rang uniden head office they told me that that is because of the walls and that it is an old system, even though the cameras are only 5 or so meters away and only 1 wall.
The picture is very grainy and you cant make out what a number plate is or what a person's face looks like when they are walking.
Called uniden head office and was told the new ones are a lot better that is the type of camera it is.
Very poor.

If you are getting a 'Record file error' message coming up on your monitor it's because you need to install a Sandisk 32GB High Endurance SD Card ($26- on eBay) instead of anything else you may have installed. I'm a technician & have installed nearly 50 of these Uniden Guardian G Series CCTV Surveillance Systems & they are quite good quality considering their price.

Bought this unit recently which has 4 camera. cameras will communicate to the main unit as soon as you turn them on, so no configuration is required, which is cool. it can record video on a SD card and can support up to 32GB SD card. the only down side is that these series do not support overwrite video function on SD card (using the latest firmware V-A2.4.5-50hz) which is a big design issue (you will need to format the SD card every few days!!!). contacted with customer support about this. Apparently in the previous firmware version (V A2.2.8-...
