Recognize these? Here's what usually causes it.
Common Causes

- Cloud storage subscription expired
- Camera firmware outdated
- Infrared sensors blocked or dirty
- Bandwidth insufficient for multiple cameras
Most fixes happen in the first 3 steps.
Security cameras should be installed at least 8 feet high to prevent tampering. Check local laws regarding recording audio and video. Never aim cameras at neighboring private property. Outdoor cameras should be rated IP65 or higher for weather resistance.

Step-by-Step Solution
Check Power Supply
Verify the camera is receiving power. For wired cameras check the outlet and power adapter. Try a different outlet. For battery cameras check the charge level in the app. For PoE cameras verify the ethernet cable is fully seated at both ends. A camera without proper power will show offline even with good WiFi.
Test WiFi Signal Strength
WiFi cameras need strong signal for reliable streaming. Check signal strength in the camera settings within the app. If signal is weak, consider moving your router closer or adding a WiFi extender near the camera. Thick walls and metal siding severely reduce signal. Aim for at least 2 bars of signal strength.
Power Cycle the Camera
Unplug the camera from power or remove the battery. Wait 30 seconds then reconnect power. For PoE cameras disconnect the ethernet cable briefly. Allow 60 to 90 seconds for the camera to fully restart and reconnect to your network. Check the app to confirm it shows online before testing live view.
Adjust Motion Detection Settings
Open camera settings and find motion detection or alerts. Set sensitivity to medium as a starting point. Define detection zones to focus on important areas and exclude high-traffic zones like streets. Test by walking through the detection area. You should receive an alert within a few seconds.
Clean Camera Lens and Sensors
Dust and debris on the lens cause blurry video. Spider webs trigger false motion alerts. Use a soft microfiber cloth to gently clean the lens. For night vision issues clean the infrared LED ring around the lens. Avoid using harsh chemicals. A clean lens dramatically improves image quality.

$18.99Update Camera Firmware
Open the camera settings in your app and check for firmware updates. Install any available updates which fix bugs and security issues. The camera may restart during the update. Do not unplug power during firmware updates. After updating test all features including live view, recording, and alerts.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Set up activity zones to monitor only the areas that matter like your front porch and driveway and exclude the street. This dramatically reduces false alerts while ensuring you never miss an actual event at your property.
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.
