Why Are My Arlo Camera Activity Zones Overlapping?
- Weak WiFi signal at camera location
- Power supply interrupted or adapter failing
- Motion sensitivity set too low or too high
Problem Description
Your Arlo Camera is experiencing issues related to activity zones overlapping. This affects your ability to control the Camera through the Arlo app, scheduled automations, and voice assistants. Specifically, the issue involves activity zones overlapping. The steps below walk you through diagnosing the root cause and applying proven fixes so your Camera works reliably again.
Why This Happens in Real Homes
Activity zones let you tell the Arlo camera which parts of the frame to watch for motion so you stop getting alerts every time a car drives past on the street. The feature requires an Arlo Secure subscription — without it, the camera records everything in its field of view with no filtering. Even with the subscription, people set up zones wrong. They draw tiny zones around their front porch and miss people approaching from the side. The zone processing happens in the cloud on older Pro 2 cameras but on-device on the Pro 4 and Ultra 2, which means the newer cameras react faster but use more battery per detection event because the onboard AI chip stays active longer.
Symptoms
- Camera shows offline in the app
- Live view fails to load or times out
- Motion detection not triggering alerts
- Night vision appears too dark or washed out
- Recorded clips are missing or corrupted
- Two-way audio not working
- Camera keeps disconnecting from WiFi
Recognize these? Here's what usually causes it.
Common Causes
- Weak WiFi signal at camera location
- Power supply interrupted or adapter failing
- Motion sensitivity set too low or too high
- 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- Camera firmware outdated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
Access activity zones in the Arlo app
Open the Arlo app, select the camera, and go to Device Settings then Activity Zones. You will see the camera live view with an overlay where you can draw rectangular or polygonal zones. Only motion inside these zones triggers recording and notifications. Motion outside the zones is ignored. This is essential for reducing false alerts from cars, pedestrians, or swaying trees.
Draw zones that cover only areas you care about
Start by identifying what you actually want to detect — a front door, a driveway entry point, a package delivery area. Draw a zone tightly around each area. Avoid including the street, sidewalk, or areas with constant movement. You can create multiple zones for the same camera. Name each zone descriptively (Front Door, Driveway, Side Gate) so notifications tell you which zone triggered.
Understand activity zone limitations
Activity zones work by analyzing pixel changes within the zone boundary. They do not use object recognition to filter — anything that moves inside the zone triggers detection. A flag waving inside your zone will trigger just like a person. Zones also do not work on the very edge of the frame due to how the motion detection algorithm processes the image. Keep zones at least 10% away from frame edges.
Test your zones with a walk test
After setting zones, have someone walk through each zone while you watch the Arlo app in live view. Verify that walking through the zone triggers an alert and walking outside the zone does not. Adjust zone boundaries based on the results. Test at different times of day — motion detection sensitivity changes with lighting conditions, especially at dawn and dusk.
Adjust zones seasonally
Trees and bushes change with seasons. A zone that avoided tree branches in winter may include them in summer when leaves grow in. If you start getting false alerts in spring or summer, check whether vegetation has grown into your zones. Adjust the zone boundaries to exclude the new growth. Similarly, seasonal sun angles can create moving shadows that trigger zones.
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.
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.
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.
