No exeriance with the Vuezone. However, A couple of years ago I went through this same process. After doing tons of research I found that standard "tv" type cameras that sent the image over coaxial cable were not for me. The resolution was not nearly high enough. The cameras bosted that they have high resolution, but the technology behind how the image is transmitted is quite old and that is where the bottle neck is. For me, I would have hated to have bought and installed a system only to find out that I could not legally prosecute because the image quality was low. SO...I decided on HD network cameras. Specifically Vivotek IP8332. They have been up and running for two years now and I am absolutely happy with their performance. As of late, the temperature has gotten down to -18F and they still work, outside, mounted under my soffits. I bought two cameras, a POE network switch, cable, and a 2Tb hard drive. All together I think I have just over $900 invested. I can add more cameras with the only cost being the cameras (~$325 each). If I buy another switch I can add 4 more cameras, and so on. If they are in an area where you can plug them in to a power outlet, there is no need for the POE switch.
These are a web server by themselves. I do have broadband going all the time, although not necessary if I do not want to veiw remotely. All images, videos are stored on my PC harddrive but you could set these up to save to a NAS (remote) hard drive, which I will do at some point.
I had a hard time dealing with the upfront cost of the cameras, but I see how nice they are and they are well worth the money if you feel you need them. As stated, I have mine mounted outside so they are always being triggered. If someone had one in a secure location they can easily be set up to text you or email you if a particular event happens. Very nice.
These did aid in prosecution of an individual. Even the police stated how nice it was to have a quality image and that they are always surprised to find that business in particular have low resolution images that really do not tell much.
My experiance, a GREAT deal. I'm sure there are other brands that do similar. This is just my experience. I will include a couple of images shot from the cameras. These cameras are mounted about 75 feet from the road to give you a frame of reference. Some of them have been cropped because I pulled them from a document I created that aided in prosecution.
I hope this helps.
