Ubiquiti UniFi Protect Camera Offline: How to Fix It

Q: Why does my UniFi Protect camera keep going offline randomly?

Random disconnections are usually caused by unstable PoE power delivery, overheating, or network congestion. Check your PoE power budget, ensure proper camera ventilation, and verify your network switch isn't overloaded with traffic.

Q: Can a full hard drive cause cameras to go offline?

Yes, when UniFi Protect storage reaches capacity (typically 90% full), cameras may go offline to prevent system instability. The system prioritizes stability over recording when storage is critically low.

Q: How do I know if my PoE switch is providing enough power?

In the UniFi Network Controller, check the PoE usage under Insights > PoE. Each camera typically needs 15.4W. If usage exceeds your switch's PoE budget, cameras will randomly lose power and go offline.

Q: What should I do if multiple cameras go offline simultaneously?

Multiple camera failures usually indicate a central issue like NVR problems, network switch failure, or power issues. Check your Dream Machine/Cloud Key status first, then verify your PoE switch is functioning properly.

Q: How long should I wait after restarting before cameras come back online?

After restarting your UniFi equipment, allow 5-10 minutes for full initialization. Cameras typically reconnect within 2-3 minutes, but the adoption process may take longer if firmware updates are applied automatically.

Abstract

The UniFi Protect camera offline error occurs when your security camera loses connection to the UniFi Dream Machine or Cloud Key. This typically happens due to Power over Ethernet (PoE) issues, network connectivity problems, or when the NVR storage becomes full.
