Any ideas anyone?

Quite separate from the door entry device, how about a little bullet
camera (or one with IR, or whatever) feeding into an AV input on the
telly? She'd need to know how to select the AV input but I expect she
could be trained. The cam could be positioned to make the best use of
the available light, which often means that the view of the caller is a
profile, which is OK I've found. Cam could be disguised if necessary.

Now that's an idea, separate the video completely from the door
opener. There's a key safe anyway so she could always tell the
visitor the number if she recognises them and, if she doesn't want to
do that, she can ask them to wait while she gets to her feet to answer
the door.

Thank you for the idea.
