Vickir.... because we don't want to get caught peeking and for some rigs that's too far to walk.... :-)
We have a kitchen window right next our front door we can glance out of, but this means they can possibly glance inside. I think the Honeywell is a good solution. Using a standard peephole wouldn't work because of the screen door that is in FRONT of the front door and you'd have to mount it too low to work anyway.
Check this website:

Good luck,
