Troubleshooting Guide for 2N Motion Detection Zone Settings
2N intercoms and IP devices offer powerful motion detection capabilities, allowing you to define specific zones for monitoring. However, when these zone settings don't work as expected, it can lead to a flood of false alerts or, worse, missed events. This guide will help you diagnose and fix common issues with 2N zone settings.
Whether you're getting alerts from outside your defined areas or no alerts at all, we'll walk you through the configuration steps to ensure your motion detection is both accurate and reliable.
### Common Symptoms of Zone Setting Problems
- Alerts from Excluded Areas: You receive motion notifications caused by movement (e.g., cars on a street) in areas you have specifically excluded.
- No Alerts from Included Areas: A person walks directly through a defined motion zone, but no alert or action is triggered.
- Settings Not Saving: You configure the zones, but the settings seem to revert to default or disappear after a while.
- Sensitivity Issues: Even minor changes, like moving tree branches or shadows, are triggering alerts despite your zone settings.
- Actions Not Triggering: The system detects motion correctly within a zone, but the corresponding action (like sending an email or making a call) does not happen.
How to Fix Your 2N Zone Settings Configuration
Most issues with 2N motion detection are rooted in the web configuration interface. Let's explore the key areas to check.
1. Accessing and Configuring Motion Detection
First, ensure you are in the right place.
- Log in to your 2N device's web administration interface.
- Navigate to the Hardware -> Camera -> Motion Detection section.
- Make sure the Motion Detection Enabled box is ticked.
2. Correctly Defining Detection Zones
This is where most errors occur. The 2N interface uses a grid system.
- Understanding the Grid: The view is divided into a grid. You can select which squares are 'active' for motion detection.
- Clearing and Setting: It's often best to click the Clear All button first to ensure no old zones are selected. Then, carefully click and drag your cursor only over the specific grid squares where you want to detect motion (e.g., your walkway, your porch). Leave all other areas (e.g., the public pavement, your neighbour's garden) unselected.
- Saving Your Changes: Crucially, you must click the Save button at the bottom of the page after defining your zones. If you navigate away without saving, your changes will be lost.
3. Fine-Tuning Sensitivity and Other Parameters
Zones alone aren't enough; they work in tandem with sensitivity settings.
- Sensitivity: This slider determines how much change in the image is required to trigger an event. A high setting (e.g., 90-100) is very sensitive and can be triggered by shadows or rain. A low setting (e.g., 20-30) requires a significant object to move. If you get false alerts, try lowering the sensitivity in increments of 10.
- Object Size: This setting helps the system ignore small movements. If you want to detect people but not cats, for example, you can try increasing the minimum object size. Experiment with this setting to find the right balance.
- Noise Level: This helps the camera distinguish between genuine motion and digital noise from the camera sensor, especially in low light. The default value is usually fine, but you can adjust it if you have persistent issues.
4. Linking Zones to Actions
Detecting motion is only useful if it triggers the correct action.
- Check Automation Settings: Navigate to the Automation section. This is where you define what happens when motion is detected.
- Create the Rule: You need a rule that looks something like this:
- Event:
MotionDetectedInWindow - Action:
SendHttpRequestorMakeCallorSendEmail
- Event:
- Ensure It's Active: Make sure the automation rule is enabled. If the rule is disabled, motion will be detected, but nothing will happen.
By systematically checking that motion detection is enabled, your zones are correctly drawn and saved, your sensitivity is properly tuned, and your automation rules are active, you can resolve nearly all issues with 2N zone settings not working.
