Is your Eufy eufyCam 3 not recording at night? This issue typically stems from power-saving settings, infrared configuration problems, or motion detection sensitivity that's calibrated for daytime conditions. Since the eufyCam 3 relies on battery optimization and AI-powered detection, nighttime recording failures can occur when these systems conflict with low-light environments. The steps below will help you restore reliable after-dark surveillance without unnecessary battery drain.
Check Night Vision and Infrared Settings
The eufyCam 3 uses infrared LEDs for night vision, but incorrect settings can prevent recording triggers even when motion occurs. Start with these foundational checks.
1
Open the Eufy Security app and verify Night Vision mode: Tap your camera, select Settings > Night Vision, and confirm it's set to "Auto" rather than "Off." If set to Off, the camera cannot detect motion in complete darkness, directly causing the Eufy eufyCam 3 not recording at night problem.
2
Test infrared LED functionality: In a dark room, cover the camera's light sensor (small dome near the lens) for 30 seconds. You should see a faint red glow from the IR LEDs through your phone's camera. No glow indicates hardware failure requiring replacement under warranty.
3
Adjust infrared intensity for your environment: In Settings > Night Vision, switch from "Auto" to "Far" if monitoring large areas (30+ feet), or "Near" for enclosed porches where IR reflection can wash out motion detection. Incorrect intensity causes the AI to miss human-shaped heat signatures.
Optimize Motion Detection for Low-Light Conditions
The eufyCam 3's AI detection behaves differently at night. Motion sensitivity and detection zones often need separate nighttime calibration.
4
Increase motion sensitivity specifically for night: Navigate to Settings > Motion Detection > Sensitivity. Raise the slider from your daytime setting by 20-30 points. Night vision frames have lower contrast, so the AI requires stronger pixel-change thresholds to register activity. Tap "Test Motion Detection" and walk through your yard after sunset to confirm triggers.
5
Verify detection type includes all relevant motion: Under Settings > Motion Detection > Detection Type, ensure "Human Detection" is enabled but consider adding "All Motion" temporarily for troubleshooting. The eufyCam 3's human-only AI can fail at night if subjects wear dark clothing or move quickly through IR-illuminated zones.
6
Remove or shrink detection zones that cover reflective surfaces: In Settings > Activity Zone, exclude areas with car headlights, street lamps, or wet pavement. These create sudden light changes that trigger false positives early in the night, after which the camera enters cooldown and misses real events. Redraw zones to focus on walkways and entry points only.
Battery Impact Warning: Increasing sensitivity and enabling "All Motion" will reduce battery life by 30-50%. After resolving the not recording at night issue, revert to "Human Detection" and optimal sensitivity, or schedule more frequent solar panel charging.
Review Recording Modes and Scheduling
The eufyCam 3 offers multiple recording modes that may conflict with nighttime operation. Scheduling errors are a hidden cause of missed recordings.
7
Disable any custom recording schedules temporarily: Go to Settings > Recording > Schedule. If you see time blocks with different modes, switch to "Always Record Events" for 48 hours. Users often create daytime-only schedules and forget to extend them, causing the Eufy eufyCam 3 not recording at night symptom.
8
Check HomeBase 3 storage and overwrite settings: Open the HomeBase device in your app, select Storage > Local Storage. If capacity exceeds 90%, the system may skip low-priority night recordings. Enable "Loop Recording" or manually archive older clips to free space. For encrypted users, verify the eMMC isn't corrupted—format only as last resort.
9
Update firmware for both camera and HomeBase 3: In Device Info, check for firmware updates. Eufy released multiple patches in 2023-2024 specifically addressing night vision detection gaps. The camera and HomeBase must run compatible versions; mismatched firmware causes silent recording failures between 10 PM and 6 AM.
Frequently Asked Questions
Why does my eufyCam 3 record during the day but stop at night even with Night Vision on?
This usually indicates the AI detection threshold is too high for infrared footage. Daytime color video has sharper edges and contrast, making human detection easier. At night, the grayscale IR image requires either higher sensitivity or closer subject distance. Adjust sensitivity upward and ensure subjects pass within 25 feet of the camera.
Can cold weather cause my eufyCam 3 to stop recording at night?
Yes. Lithium batteries in the eufyCam 3 experience reduced performance below 32°F (0°C). The camera may preserve remaining charge by disabling non-essential functions including recording. If you experience seasonal Eufy eufyCam 3 not recording at night issues, install the camera in a sheltered location or use Eufy's solar panel with cold-weather optimization enabled.
How do I know if my night recordings are missing versus not being notified?
Check the Events tab filtered to "All" rather than "Person" or "Vehicle." Then review Storage > Recorded Videos directly on the HomeBase. If clips exist without alerts, your notification settings are the problem. If no clips exist despite visible motion, follow the detection troubleshooting above.
