Why Is UniFi Protect Showing Duplicate Camera Entries?
- Camera re-adopted without removing the old entry
- IP/MAC change created a new entry
- Ghost entry from a previous adoption
Problem Description
UniFi Protect shows two entries for the same camera — one connected and one disconnected or offline. Duplicates appear when a camera is factory reset and re-adopted without first removing the old device entry from Protect. The old entry retains historical recordings while the new entry is the active camera.
Why This Happens in Real Homes
Duplicate camera entries in UniFi Protect are usually a leftover ghost record — the camera was re-adopted, changed IP, or was moved without the old entry being removed, so the controller shows both the stale (offline) and the active (online) one. It's a bookkeeping issue, not two cameras.
Identify which entry is live (online, streaming) and forget/remove the stale offline duplicate from the device list, then re-adopt cleanly if needed. Reserving a DHCP IP for the camera prevents new entries appearing when its address changes. Restart the controller to refresh the list and update its firmware. Make sure only one controller is managing the camera; two controllers fighting over it can also spawn duplicates.
Symptoms
- Duplicate camera entries
- Two entries for one camera
- Camera listed twice
- Ghost/old entry
- Duplicate in the device list
- Old entry won't clear
- Two of the same camera
- Redundant entry
Recognize these? Here's what usually causes it.
Common Causes
- Camera re-adopted without removing the old entry
- IP/MAC change created a new entry
- Ghost entry from a previous adoption
- Camera moved networks/controllers
- Stale device record
- Adoption glitch
- Firmware/controller quirk
- Manual re-add
Most fixes happen in the first 3 steps.
Do not delete active camera record by mistake during cleanup.
Tools & Requirements
Step-by-Step Solution
Identify which entry is the active camera
In Protect: go to Devices. If two entries exist for the same camera: one should show 'Connected' (the active camera) and the other shows 'Disconnected' or 'Offline.' The duplicate usually appeared because the camera was factory reset and re-adopted without removing the old entry first. The old entry retains historical recordings. The new entry has no history but is actively streaming. Note which is which before removing anything.
Remove the stale duplicate entry
In Protect: Devices > select the disconnected/offline duplicate > Remove. This removes the device entry from Protect. Removing a device deletes its associated recordings from the timeline. If you want to keep old recordings from the stale entry: export them first (Protect > Timeline > select clips > Download). After removing: only the active camera entry remains. The camera continues working normally.
Prevent duplicates by removing before re-adopting
Duplicates happen when you factory reset a camera and re-adopt it without removing the old entry. Correct procedure: (1) In Protect, go to Devices > select the camera > Remove. This deregisters the camera from Protect. (2) Factory reset the camera if needed. (3) Re-adopt it in Protect — it appears as a new device with a clean entry. Following this order prevents duplicate entries.
Check for cameras with changed MAC addresses
In rare cases: a firmware update or hardware replacement changes the camera's MAC address. Protect identifies cameras by MAC — a different MAC means Protect treats it as a new camera, creating a duplicate. This should not happen during normal firmware updates but can occur if the camera's network module is replaced during a warranty repair. If you received a refurbished camera: it has a different MAC and will always appear as a new device.
Restart Protect to refresh the device list
If removing the duplicate does not stick (it reappears after a refresh): Protect's device database may have a sync issue. Restart the Protect application: in UniFi OS, go to Applications > Protect > Restart. This is different from restarting the entire UniFi OS — it only restarts the Protect application. After restart (1-2 minutes): check the device list. If the duplicate is still present: restart the entire UniFi OS (Settings > System > Restart) for a full database reinitialize.
Quick Solutions
Still having issues? This is usually the deeper cause below.
Camera issues that start suddenly almost always trace back to an upload bandwidth drop — run a speed test before assuming hardware failure.
Always verify recording continuity before deleting duplicate entries.
Live view problems that start suddenly usually trace back to an upload speed drop — the camera itself is fine, the bandwidth path to the cloud isn't.
- Camera re-adopted without removing the old entry
- IP/MAC change created a new entry
- Ghost entry from a previous adoption
- Camera moved networks/controllers
- Stale device record
