Video intercom, another ancient idea come true

Another ancient prediction come true. This one from June 1993, an idea I had and developed with my colleague Chris Winter. Simple idea, just link a video camera on the front door to the network so you can screen people remotely for entry.

Here’s the latest incarnation in today’s paper. Surprising that it has taken so long really. I was concerned in 1993 that it may have been too obvious:

Here’s my original description:

Videophone Intercom, 10 Jun 1993
Ian Pearson, Chris Winter

To summarise, the videophone intercom is a device located at a household front door. A caller would push the button, whereupon an autodialler would call up the resident at his remote location (e.g. at work). The resident would then be able to identify the caller, check ID, and then arrange access if appropriate.
The cost of video cameras on chips has fallen dramatically – in bulk, they can shortly be obtained for as little as £10. Many users will soon have videophones on their desks or at home. Autodiallers and intercom systems can also be made very cheaply. The whole system cost could therefore be quite low. Such devices would offer a much higher level of security than simple audio systems. The number to be dialled could be changed remotely.
Useful additions might be to add a video terminal or phone inside the house, perhaps even just on the inside of the door to give enhanced security before opening the door to a stranger. There need be no way of telling from the door whether the resident is using his home display or a remote videophone.
There are equivalent other industrial uses, such as remotely manning a salesroom or stores.
