How to Fix Ineffective Blink Camera Activity Zones
Blink's Activity Zones feature is a powerful tool designed to reduce unwanted motion alerts by letting you specify exactly which areas of the camera's view you want to monitor. However, if you're still being bombarded with notifications from ignored zones, or if motion is being missed entirely, it can be very frustrating. This guide will help you troubleshoot and configure your Activity Zones for optimal performance.
Understanding how these zones work is the first step to making them effective.
### Understanding How Activity Zones Function
It's important to know that Activity Zones are a digital filter, not a physical one.
- The camera's passive infrared (PIR) motion sensor first detects motion anywhere in its field of view.
- The camera then wakes up and analyses the image.
- It checks to see if the detected motion falls within the 'active' blue-tinted squares you have selected.
- If the motion is within an active zone, it sends you a notification and records a clip. If the motion is only in an inactive (grey) zone, it is supposed to be ignored.
This process means that things like rapid lighting changes can sometimes trick the system into recording, as the change affects the whole image.
## Troubleshooting Steps for Ineffective Zones
If you're getting alerts from greyed-out areas, work through these steps.
### 1. Check Your Zone Configuration
The most common issue is a simple misconfiguration.
- Active vs. Inactive: In the Blink app, when setting up your zones, you see a grid overlay. You must tap on the squares where you want to detect motion. These selected squares will become active (often appearing clear or with a blue tint), while the deselected squares will be greyed out and inactive. A common mistake is to do this in reverse, grey-ing out the areas you want to watch.
- Save Your Changes: Always make sure you tap 'Done' or 'Save' after making changes to your zones. If you just exit the screen, your new layout may not be saved.
- Update the Zones: After saving, it's good practice to go back into the Activity Zones setting to confirm your new layout is still there.
### 2. Reset and Re-configure
Sometimes, the settings can get stuck. A fresh start can often resolve this.
- Go to the Activity Zones setting for the problematic camera.
- Tap 'Reset Zones'. This will clear all your customisation.
- Carefully re-select the zones you wish to make active.
- Tap 'Done' to save the new configuration.
### 3. Power Cycle the System
A simple reboot can often fix temporary software glitches between the camera, the Sync Module, and the Blink servers.
- Power Cycle the Camera: Remove the batteries from your Blink camera, wait 30 seconds, and then reinsert them.
- Power Cycle the Sync Module: Unplug your Sync Module from power, wait 30 seconds, and plug it back in.
- Allow a few minutes for the system to come back online fully before testing the motion zones again.
### 4. Consider Environmental Factors
- Clipping Edges: A car driving past might have its bumper just clip the very edge of an active zone, triggering an alert even if most of the car is in an inactive zone. Try making your active zones slightly smaller, leaving a buffer from the edges of roads or pavements.
- Shadows and Light: Long shadows moving across your garden as the sun moves, or the headlights of a car sweeping across your property, can be interpreted as motion by the camera. While zones can help, they are not always foolproof against these kinds of triggers. Adjusting the camera's sensitivity setting can sometimes help in these situations.
By methodically checking your configuration and considering environmental factors, you can significantly improve the accuracy of your Blink Activity Zones.
