SafetyVue Giant Peephole for Home Security

I had no problem installing it in a steel door. Make sure you get a high quality hole saw. Visibility was good during the day, not that great at night, but still usable. I am very satisfied with this product.

Product is exactly what it says. Gives a much better door eye view to see who is at your door.

I've had this item before and this one is replaceing the one that was on my door before the door was replaced. This is the best for those whe live in an apartment/condo where you cannot see out the door or run to a window to look who is knocking. You can see very clearly who it is from far away.

Fairly easy to install. I'm not very handy, and it took me about a half hour. Make sure you have the correct size (2 1/8") hole saw. They sell them at hardware stores for about $10-$15 (I wish one came with the peephole). The peephole gives you a nice, big image. In daylight, the image is excellent. At night, however, you'll need one or two really bright lights on to be able to make out the image. Remember, it's actually a camera... not a true peephole. So, the image is bouncing off a mirror before it gets to your eyes. Therefore, everything that's on the left on the screen is actually on the right outside your door. Also, if you install it too high up on your door, you'll have trouble seeing shorter visitors (unless they step back far enough to come into view). Overall, it's a good product. I'm glad I got it.
