Peephole Installation Cost Calculator

A professionally installed door viewer typically runs $50 to $250, and the viewer type is what sets the range. A simple standard or wide-angle glass peephole is $50 to $130 installed, a digital peephole camera with an interior screen is $150 to $300, and a smart Wi-Fi video viewer is $200 to $400+. The device itself is cheap for a basic peephole ($10–$30) and most of the cost is the $50–$150 labor to drill and fit it; on electronic viewers the device is the bigger share. Your door material (wood is easy to drill, metal/steel is the hardest), install type (reusing an existing hole is cheapest, drilling new is standard, repositioning costs more), and extras like Wi-Fi setup or patching an old hole move the number. A ~$50 job minimum applies. Enter your viewer type and door above for a localized estimate.

There are four common types, in rising order of cost and features. A standard 180° peephole (~$60 installed) is a simple glass lens — cheap, reliable, no power, but a small view you squint through. A wide-angle 200°+ peephole (~$80) is the same idea with a broader field of view and fewer blind spots. A digital peephole camera (~$180) replaces the lens with a small camera and an interior LCD screen — far easier to see, usually with night vision and recording, and a big help for low vision or anyone who can't reach a fixed lens. A smart Wi-Fi video viewer (~$250) adds phone/app viewing, motion alerts, and recording, like a doorbell camera built into the door. Optical peepholes need no power and never go offline; digital and smart viewers trade that simplicity for a screen, recording, and remote monitoring. The calculator lets you compare all four.

For a basic peephole in a wood or fiberglass door, yes — it's one of the easiest door upgrades, about a 15–30 minute job. You mark eye level, drill a hole of the diameter the viewer specifies (basic peepholes often need ~1/2 inch; digital and smart units need a larger bore), then insert the two halves and screw them together hand-tight. Drilling from both sides or using a backer block avoids splintering the exit face. Digital and smart viewers are still DIY-friendly but add a larger hole, batteries, and Wi-Fi/app setup. Where a pro is worth it: metal or steel doors (hard to drill cleanly and need the right bits), repositioning that involves filling and patching an old hole, a nice door where a botched hole would show, or simply if you're not comfortable drilling into your entry door. This calculator prices professional installation so you can see what DIY would save.

Standard height is eye level for an average adult — about 58 to 66 inches from the floor, with 60–62 inches most common. The right height really depends on who uses the door: install lower (around 50–58 inches) for shorter household members or children, and for wheelchair or ADA accessibility use roughly 43–48 inches, seated eye level. Many households add a second, lower viewer so everyone can see out, which is why the calculator offers a lower/ADA-height option and a multiple-heights option (each adds a per-viewer charge). A digital viewer sidesteps the problem to a degree — because you look at an interior screen rather than press your eye to a fixed lens, the screen can be mounted at a convenient height and serve varied users. Keep the bore in the center of the door panel, away from the edge and any hardware or reinforcement.

It's usually worth it if you value easier viewing, a record of who came to the door, or remote monitoring — and less so if you just want a cheap way to check the porch. A digital viewer's interior screen is far easier than squinting through a tiny lens, which matters a lot for low vision, older adults, or children, and it typically adds night vision (traditional peepholes are nearly useless in the dark) plus photo/video recording. A smart Wi-Fi viewer goes further with phone alerts and viewing from anywhere, essentially a doorbell camera inside the door — great for security-conscious or smart-home users, though some cloud recording features carry a subscription. The trade-offs are cost (traditional $50–$130 vs. digital $150–$300 vs. smart $200–$400+) and dependence on batteries, Wi-Fi, and app setup. For a basic need on a budget, a wide-angle optical peephole is perfectly fine.

It's one of the fastest door upgrades. A basic optical peephole takes about 15 to 30 minutes — mark, drill, and screw the two halves together. A digital camera viewer runs 30 to 45 minutes because the hole is larger and you mount the camera, interior screen, and batteries. A smart Wi-Fi viewer is 45 to 60 minutes, with the extra time going to connecting it to Wi-Fi and the app. Door material and install type shift the clock: a metal or steel door drills slower than wood, reusing an existing hole skips the drilling entirely, and repositioning takes longest because you fill and patch the old hole and wait for the patch and paint to dry. Adding multiple viewers or heights adds time per unit. Even so, most single-viewer jobs are finished in under an hour.
