Summary: Even though the picture frame is sound capable (for movies), the camera monitor does not reproduce audio form the cameras. I have Trendnet sound enabled cameras and was shocked to find out this monitor could not reproduce the camera's audio.
Summary: This unit works OK with older TrendNet IP cameras, but is not compatible with their newer cameras using 802.11N wireless and/or newer web server firmware, such as the TV-IP512WM. According to their support people, there is no plan to upgrade the TV-M7 for comatibiity. Also, it does not appear to be able to control the camera steering on a camera such as the TV-IP422W. Altogether, a disappointing purchase.
Summary: I purchased this TV-M7 monitor to allow me to watch and listen to our handicapped son in his bedroom at night. Unfortunately, the TV-M7 software will not do audio when it is connected to a Trendnet camera with audio. It does display the video fine. I also found that the TV-M7 was very picky about WIFI setup and it would only work on my older WEP access point. I could not get it to work on WPA.
