Your Mac is already a security camera. You just never used it that way.

MacBook webcams sit there all day doing nothing, while you pay for another gadget, another app, another subscription. SpyCam flips that.

SpyCam (spycam.app) turns your Mac into a hidden, motion-activated camera that keeps watching when you step out.

What SpyCam actually fixes

Most people don’t need 24/7 recording. They need receipts.

A delivery that “never arrived”. A roommate “who didn’t touch it”. An office desk that keeps getting picked clean.

SpyCam records when motion hits. That’s the whole point.

Motion detection that doesn’t waste your storage

SpyCam focuses on motion-triggered recording, so you don’t end up digging through hours of dead video. You can tune sensitivity to catch small movement or only big action.

And yes, you can control the boring but crucial knobs: video length, cooldown periods between clips, and how picky the detector gets.

Stealth mode, not theater

If the goal is to catch what happens when you’re gone, the app can’t quit the moment your screen locks.

SpyCam keeps monitoring and recording with your screen locked. It can even keep running through sleep if you start a session first.

There’s also a “Surveillance Mode” that only runs when the screen is locked. Lock to arm. Unlock to disarm. Clean.

Privacy that doesn’t feel like a trap

A security camera app that phones home feels wrong.

SpyCam says it processes locally and doesn’t collect data from your Mac. That matters when the camera points at your home, your office, your life.

Who this is for

Anyone who wants a cheap home cam without buying hardware
Remote workers who leave gear on a desk
Apartment dwellers who want eyes on the door
Small teams that need lightweight monitoring in a shared space

What you need to run it

SpyCam requires macOS 13.0 (Ventura) or later and installs from the Mac App Store.

If you want a simple “set it and forget it” watcher, spycam.app is a straight shot: motion triggers, custom controls, and a lock-screen-first workflow that fits real life.
