I've googled myself silly and can't find a door intercom that either takes a photo of the person pushing the doorbell, or a short video, preferably stored on a memory card.
I want to be able to see and speak to the person ringing the bell from inside my house and have an automatic photo/record facility so that I can see who has called whilst I've been out.
I've found what I want without the photo/record facility for around £100 but must have the photo/record.
Thanks for your time, Rojash, but that's a fail because:
It has to installed on my door which is behind locked gates;
No intercom facility to tell cold callers to politely go away.
I am off to bed and don't want to start Googling for you because I get caught up in a search
and would still be here in hours.
But try using Google with different search keywords - look for a company that sells loads of these things and/or a review of technology site. It might be easier than chasing the products themselves.
I hope that you find something, if not perhaps your local security firms might be able to help you.
You could try asking your local police security expert. They might know -I'm sure the Poole ones who oversee the superhomes at Sandbanks (just an example local to me) would know about this stuff, for example.
