In our block of flats there are 7 analogue, audio only door entry phones. There are enough free wires in the telephone cable to add video without rewiring.
It was put to me that it would be a waste of money to rip out the DEPs and replace them with digital and was happy to hear this. I suggested that in order to add video that the we have each flat supplied with small flat led screens, independent of the existing audio system, and take the feed from the security camera at the front door, via the DVR's outputs. I do not want to use wifi as the connection but want a wired connection. The engineer told me for that to work, each phone would need an amplifier which if true would lead to an expensive installation as each amplifier would cost £120. Is the engineer's advice correct?
