I’ve been using 720p Foscam cameras for several years. They are reliable, have great features, and their support is pretty darn good. Their warranty is outstanding! They replaced one of my cameras that was vandalized when the cord was cut off although obviously it was not a warranty issue.
Currently we have several FI9303P 720p cameras in use and have had no problems with them.
If you need an inexpensive (under $60) good, weatherproof, reliable camera with lots of features, this is the one to buy. Night vision is good. The camera will email you motion detected video or stills, upload, or send alerts. It will also FTP to your network attached storage or even a website or the cloud. It also works well and is supported in almost all of the camera management software packages.
At sometime in the future we will upgrade our cameras to higher resolution and expect the same if not better quality.
