WiFi Light Bulb Security Cameras: How They Work and What to Buy

A light bulb security camera is one of the simplest ways to add monitoring to your home. It screws into a standard E27 light socket, draws power from the socket, and connects to your WiFi, so there are no batteries to recharge and no wires to run. Here is how they work and what to look for before you buy.

How light bulb cameras work

The camera sits where a bulb would, powered straight from the socket. Once it is on your WiFi, you view the live feed and recordings in a companion app from anywhere. Most models pan and tilt for a full 360-degree view, detect motion, and send alerts to your phone. Footage usually records to a microSD card, cloud storage, or both.

What to look for

• Resolution ranges from 1080p to 2K and higher. 1080p is fine for general monitoring; 2K gives you clearer detail and more room to zoom.
• Pan and tilt (PTZ) lets the camera sweep a whole room rather than covering one fixed angle.
• Night vision comes in two flavors: infrared for discreet black-and-white footage, and full-color night vision that uses a built-in light.
• Two-way audio lets you hear and speak through the camera, useful for visitors, pets, or kids.
• Motion detection and alerts notify you the moment something moves, so you are not scrubbing through hours of footage.
• Storage options matter for cost. Local microSD has no subscription; cloud adds a fee but keeps footage safe if the camera is taken.

Where they work best

Light bulb cameras shine in covered porches, garages, hallways, stairwells, and any spot with an existing socket. For fully exposed outdoor areas, choose a model rated for weather, or pair a bulb camera under cover with a dedicated outdoor camera.
