The viewing tube is somewhat larger than many other standard peephole viewer, offering a better field of view. You can apply a thin coat of silicon sealant to the inside and outside flanges before installing the unit, to help keep moisture out.

- Its material is solid brass,high quality door viewer and has a nice 220-degree visual angle.

## Questions & Answers

**Q: what size drill bit will I need?**
A: I used a millimeter step drill bit with a hex shank in my electric drill.  This was what made it possible to install a viewer at a low cost and have one that was large enough I can actually see through!

**Q: Does it install over a regular peephole, or does it require drilling?**
A: Mine required drilling

**Q: can use with Metal Door 1.8mm ?**
A: The specifications state what door thickness this can be used on. If you meant 18cm, that is a little over 3" thick. Check the specs. 1.8mm is very thin.

**Q: Do i need another piece to go with device. And how can i just use this piece to connect to my phone.  This is my first time using this an need some ad**
A: First, this is not for your phone,  It is a door viewer that you install in a house door to view who is at your door.  No other parts needed for that intended purpose.

I love this product, it fit perfectly on my door and it looks amazing!!

### ⭐⭐⭐⭐⭐ Every front door should have a peephole
*by R***N on September 10, 2018*

We moved into a new home, and one of the first things that we noticed was that the front door had no peephole. I originally wanted to get a doorbell camera or security camera, but then I realized that we should probable have this low tech solution to knowing who is at the door first. Install: This install took a bit longer than I expected because, after it arrived, I realized that my drill bit kit does not include the 5/8" bit required. So I had to order one of those and wait for it to arrive. Once it did, the install was very quick and easy. I picked an aesthetically pleasing location near the center of my French doors at eye level. I drilled a 1/8" pilot hole all the way through, trying to make sure that the resultant hole was as perpendicular to the door as possible. I then started a 5/8" hole on both sides of the door to prevent splintering when the drill bit comes through the back. Then finished off the hole. The peephole slide in easily and screwed down for the perfect fit. It looks very nice, and the view through it is very clear, especially during the day. This does provide a wider view than I am used to from my previous homes, but I do not think it approaches the 220° that it is advertised at. At that angle, I would have expected to see around to the door itself and all the was to the ground. I have the peephole installed about 5-1/4' height, and I can see the ground about 3' from the door. If there is a package directly at the doorstep I wouldn't be able to see it. It is still an improvement over what I was used to, and it will hold us over longer enough to add a higher tech solution to supplement it.
