How to Fix UniFi Protect Camera Live View Black Screen
- Insufficient PoE power browning out the sensor
- Night mode/IR issue in the dark
- Stream/encoder glitch
Problem Description
A UniFi Protect camera shows a black screen in live view — the camera is listed as connected but the video feed is completely dark or shows "No Video." The video encoder may be frozen, IR/exposure settings may be wrong, video streaming ports may be blocked by a firewall, the browser may be incompatible, or the camera hardware may be defective.
Why This Happens in Real Homes
A UniFi Protect camera showing a black screen in live view has the stream running but no usable image — most often an underpowered camera (insufficient PoE brownouts the sensor), an encoder glitch, or, in the dark, a night-vision/IR issue. A privacy zone masking the whole frame is an easy-to-miss cause.
Confirm adequate PoE power, then restart the camera to clear an encoder glitch and update its firmware. If it's black only at night, check IR/night mode and provide a little ambient light to test. Replace a suspect cable, and make sure no privacy zone is covering the image. A persistently black picture on a well-powered, restarted camera with a clean lens may indicate a failing sensor needing UI support.
Symptoms
- Black screen in live view
- No image, just black
- Camera online but black
- Black live view
- Video is black
- No picture in the stream
- Black frame
- Stream loads but black
Recognize these? Here's what usually causes it.
Common Causes
- Insufficient PoE power browning out the sensor
- Night mode/IR issue in the dark
- Stream/encoder glitch
- Firmware issue
- Bad cable/packet loss
- Camera needs a restart
- Privacy zone covering the view
- Lens obstruction/failure
Most fixes happen in the first 3 steps.
Do not assume camera hardware failure before profile and path checks.
Tools & Requirements
Step-by-Step Solution
Restart the camera from the Protect interface
A black live view with the camera showing as 'Connected' usually means the video encoder is frozen. In Protect: Devices > select the camera > Settings > Restart. Wait 60-90 seconds for the camera to reboot and reinitialize the video stream. After restart: check live view. If the stream appears: the encoder was stuck. If the screen remains black: the issue is deeper — check network and hardware below.
Check the camera's IR mode and exposure settings
If the live view shows a very dark image that appears black: the camera's IR (infrared) mode or exposure may be misconfigured. In Protect: Devices > select camera > Settings > Display. Check: IR LED Mode (set to 'Auto', not 'Off'), Exposure (set to 'Auto', not manually locked to a very low value), HDR mode (enable for high-contrast scenes). If the camera is pointed at a bright light source (sun, spotlight): auto-exposure may darken the entire frame. Adjust the camera angle to avoid direct bright light in the field of view.
Verify the camera's network connection
A black screen can mean the camera is connected for management but the video stream is blocked. Check the camera's switch port: in the UniFi Network app, verify the port shows active with no errors. If using VLANs: the camera VLAN must allow video streaming traffic to the NVR (TCP ports 7443, 7447, 7550, and RTSP 554). A firewall rule blocking video ports but allowing management ports causes exactly this symptom: camera shows 'Connected' but no video.
Try a different browser or the mobile app
If the black screen only appears in the web UI: the issue may be browser-related. Protect's web player uses WebRTC and RTSP — some browsers or browser extensions block these protocols. Try: a different browser (Chrome is most compatible), disable ad blockers and privacy extensions temporarily, or use the UniFi Protect mobile app. If the app shows video but the browser does not: the browser is blocking the video stream. If both are black: the issue is the camera or network, not the viewer.
Factory reset the camera if all else fails
If the camera is connected, network is good, settings are correct, and no video appears from any viewer: factory reset. Press and hold the reset button on the camera for 10-15 seconds until the LED flashes. The camera resets and enters adoption mode. Remove the old entry in Protect (Devices > Remove), then re-adopt the camera as a new device. After adoption: the camera should stream immediately. If still no video after a clean adoption: the camera's image sensor may be defective — contact Ubiquiti support for warranty replacement.
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.
A black screen with active events often indicates render/profile path issues, not full camera outage.
A black screen after connecting is almost always the IR cut filter stuck mid-position — a power cycle resets the mechanical component in under a minute.

- Night mode/IR issue in the dark
- Stream/encoder glitch
- Firmware issue
- Bad cable/packet loss
