Light bulb cameras have five main disadvantages: physical vulnerability to theft, dependence on an active light socket, limited mounting angle control, outdoor exposure risk, and WiFi reliability constraints that wired PoE systems don't share.
The format's biggest weakness is that anyone who can reach the socket can simply unscrew the camera — a real concern for low-mounted fixtures. Placement is also dictated by where your sockets already are, not where coverage is ideal. Outdoor light bulb cameras handle standard rain but aren't built for prolonged direct exposure to heavy weather. And because light bulb cameras run on WiFi, a congested or weak signal degrades live video and motion alert speed in ways a hardwired PoE camera never experiences.
- Light bulb cameras require a powered E26/E27 socket — the camera goes offline if the socket is switched off.
- WESECUU bulb cameras offer 355° pan and 90° tilt via app, but physical placement still determines the coverage cone.
- Local microSD storage maxes out at 128GB on WESECUU bulb cameras — no footage is retained beyond that loop capacity without cloud storage.
- AI human detection accuracy on bulb cameras decreases in pure IR infrared mode — adequate lighting improves classification reliability.
- WESECUU bulb cameras are rated for outdoor use but manufacturer guidance recommends installation under eaves, not in fully exposed positions.
