Tools & Requirements
Step-by-Step Solution
Enable Spotlight in Camera Settings
In the Arlo app, go to your Ultra 2 camera > Settings > Spotlight. Toggle Spotlight to On. Set the behavior to Motion Activated so the spotlight turns on when the camera detects motion at night. You can also adjust spotlight brightness (Low, Medium, High) and the duration it stays on after motion stops (10-30 seconds).
Check Mode Rules for Spotlight
The Arlo app uses Modes (Armed, Disarmed, Geofencing, Schedule) that control what the camera does during motion events. Go to Mode > select the active mode > Rules for your Ultra 2. Make sure Turn Spotlight On is checked under the motion trigger actions. If the spotlight option is not selected in the active mode, the spotlight will not activate even if enabled in camera settings.
Charge the Battery Above 30%
The Arlo Ultra 2 spotlight draws significant power — up to 8W at full brightness. When battery level drops below approximately 15-20%, the camera may disable the spotlight to conserve power for recording and WiFi. Charge the camera battery to at least 30% using the magnetic charging cable that connects to the port on the back of the camera.
Test Spotlight in Live View
Open the Arlo app and start a live view of your Ultra 2 camera in a dark environment (at night or in a dark room). Look for the spotlight toggle icon on the live view toolbar — tap it to manually turn the spotlight on. If the spotlight turns on manually but not on motion detection, the issue is in the mode rules. If it does not turn on at all, the LED hardware may need service.
Update Camera Firmware
In the Arlo app, go to Settings > My Devices > select your Ultra 2 > Device Info > Firmware. Install any available updates. Spotlight control bugs have been addressed in several Ultra 2 firmware updates. The update takes 5-10 minutes and the camera must remain powered and connected during the process.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If flickering only happens on dimming, the issue is almost always the dimmer's minimum-load setting, not the bulb — it's drawing less current than the dimmer expects.
Keep the camera within strong WiFi range to avoid delayed spotlight triggers.
Battery-related failures are almost always flagged too late — the device degrades silently for days before the app catches up to what's actually happening.
- Spotlight disabled in camera settings
- Battery too low for spotlight
