I have finally got round to setting up the CCTV at my own house. I have used a Alien Pro DVR and have linked it into the house aerial amp via a modulator. I also wired it direct to the lounge tv via a composite signal as i had the cable there. The DVR has a link to the router and i have full access via the internet. I also have live pictures on my Android smart phone, although only if within a WiFi signal. It could be set up to ping, email or text me when movement is seen on the camera but i am not bothered about that.
The software used is cctvwindow.com
