How Do I Set Up the Ring Peephole Cam?
- Existing peephole size/door thickness mismatch
- Inner/outer pieces not clamped correctly
- Weak WiFi at the door
Problem Description
You are setting up the Ring Peephole Cam to replace your existing door peephole with a video doorbell. Remove your existing peephole first (unscrew from the inside of the door). The Peephole Cam threads into the same hole. It works on doors 34-55mm thick. This guide covers removing the old peephole, installing the camera, and app setup.
Why This Happens in Real Homes
The Ring Peephole Cam replaces your existing door peephole, so the first thing to confirm is fit: it's made for standard peephole holes and a range of door thicknesses, and it clamps between an outer camera piece and an inner unit. Get the door-thickness match right before you start.
Charge it, clamp the two halves snugly and level (a crooked install gives a tilted view), then pair on 2.4GHz WiFi. The front door sits at the edge of WiFi, so confirm the signal reaches it; set up knock detection in the app if you want alerts when someone raps instead of ringing.
Symptoms
- Unsure how to replace the peephole
- Doorbell will not fit the door
- Setup will not connect to WiFi
- Camera crooked after install
- App cannot find it
- Knock detection not working
- Battery/charging questions
- Will not complete pairing
Recognize these? Here's what usually causes it.
Common Causes
- Existing peephole size/door thickness mismatch
- Inner/outer pieces not clamped correctly
- Weak WiFi at the door
- Phone on 5GHz during setup
- Camera not level when tightened
- Knock sensor not calibrated
- Battery not charged
- Not in setup mode
Most fixes happen in the first 3 steps.
Hardwired installation involves working with electrical wiring. Turn off the breaker before touching any wires. If you are not comfortable with basic wiring hire a licensed electrician. Some older homes may need a transformer upgrade from 10V to the 16-24V required by modern video doorbells.

Step-by-Step Solution
Remove your existing peephole
The Ring Peephole Cam replaces your door existing peephole. From inside the door, unscrew the peephole barrel by turning it counterclockwise. If it is tight, use pliers wrapped in cloth to avoid scratching. Pull the inner part through the door from inside. Note the door thickness — the Ring Peephole Cam fits doors 1.375 to 2.125 inches thick. If your door is outside this range, you need an adapter.
Install the Peephole Cam
Insert the outer unit (camera side) through the peephole hole from outside. From inside, place the mounting plate over the barrel, then attach the inner unit. The inner unit connects to the outer unit through the door with a barrel connector. Tighten the thumb screw to secure. The device should be snug against both sides of the door. If the door is thin, use the included spacer ring.
Charge and power on
The Ring Peephole Cam runs on a rechargeable battery. Charge it fully via the USB-C port on the inner unit before or after installation. A full charge lasts 2-6 months depending on usage. The inner unit has a built-in display that shows a live view of the outside — you can see who is at the door without opening the Ring app.
Set up in the Ring app
Open the Ring app, tap Set Up a Device, and select Peephole Cam. Follow the pairing instructions. Connect to 2.4GHz WiFi. After setup, configure motion detection, notification preferences, and knock detection. The Peephole Cam has a knock sensor that detects physical knocking on the door and sends an alert — useful for visitors who do not press the doorbell button.
Adjust for apartment or rental considerations
The Peephole Cam is designed for apartments and rentals where you cannot modify the door frame. It installs without screws or drilling. When you move, remove it and reinstall the original peephole. Check your lease — some landlords restrict smart device installation. The camera faces the hallway, which may be a shared space — consider privacy implications and local recording laws for shared areas.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Set up motion scheduling or snooze alerts during times when regular activity is expected like when kids come home from school. Use pre-recorded quick replies so the doorbell can respond to visitors automatically when you cannot answer.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
