Here's a video demonstrating the Foscam FI8916W. The camera was supplied by Smartcamdirect - and is available from their ebay store for £74.
There are many uses for a wireless camera like this - let me give you one example of what I'll be using this for …..I work 35 miles away from where I live and in winter snow rarely falls at the office. Snow can however come down quite heavily at home. Therefore the other year I set up a webcam to stream direct to my phone for the sole purpose of monitoring the amount of snow on the road outside my house. The idea was that if it started to get too deep, I'd catch an earlier train home so that I stood a better chance of driving home from the station. Using a webcam for this had some significant drawbacks - I needed to leave a computer on all day and the webcam wire could only stretch so far away from the PC. This winter, things will be a lot easier…I'll be using this wireless IP camera instead.
Although I managed to get most of the functions of this camera working I still think that the manufacturers have an massive amount to learn about simplifying the user interface and set-up process. I know many people who are competent with computers that would really struggle setting up an IP camera for remote viewing. So unless you are happy configuring static IPs, and port forwarding on your router then you may find that setting up an IP camera can be a very frustrating and confusing experience.
I fear that now I've put this video out, I may get inundated with requests for help from people who are unable to get their IP cameras working properly. Unfortunately, but understandably, I'm not really enthusiastic about providing IT support in my spare time.
