Ok you geeks - we "pipe" a front of the house camera feed through the RF cables to a number of TVs in our multi story home. Used a 1989 CCTV tape recorder to date and time stamp the video. This machine has now croaked (they should last longer than this......).
Anyway the question is how can I now in 2014 technology time stamp the video?!
That is without ending up a financial cripple.
