Good Thinking.
If there is light at your back, the security peep-hole may alert the person on the exterior. Here's what we do.
We installed a disc / pendulum that keeps the peep-hole continuely covered. When we approach the door we cover the disc /peephole whith our cuped hand. Put eye to hand and lift a small lever to look through the peephole.
We have also installed a separate one for the kids.
We also have our property "Posted."
Best regards,
