Swann Vehicle Detection Failed? Tuning Your Settings

Is Your Swann Camera Missing Vehicle Detections?

Swann's smart security systems with vehicle detection technology are designed to provide you with more relevant alerts, filtering out general motion to specifically notify you when a car arrives or leaves your property. However, if this feature isn't working as expected—either missing vehicles entirely or sending false alerts—it can diminish the effectiveness of your security setup.

Getting vehicle detection to work perfectly often requires more than just enabling the feature. It involves a combination of correct camera placement, careful configuration of detection zones, and sensitivity adjustments. This guide will help you troubleshoot common issues and fine-tune your Swann system for accurate and reliable vehicle detection.

Common Reasons for Vehicle Detection Failure

If you're not getting the alerts you expect, it's likely due to one of these factors:

• Improper Camera Placement: The camera's angle, height, and field of view are critical for the algorithm to recognise a vehicle's shape.
• Poorly Defined Detection Zones: The area you've marked for detection might not cover the path where vehicles travel.
• Incorrect Sensitivity Levels: The sensitivity might be set too low to pick up vehicles or so high that it's triggered by irrelevant motion.
• Outdated Firmware: Swann frequently releases firmware updates that improve the accuracy of their detection algorithms.
• Environmental Factors: Poor lighting, heavy rain, or obstructions like tree branches can interfere with detection.

Step-by-Step Guide to Fix Vehicle Detection

Follow these steps to diagnose and correct the problem with your Swann system.

1. Check Camera Placement and Angle

The way your camera sees the world directly impacts its ability to identify objects.

• Optimal Height: Mount your camera at a height of 2-3 metres (7-10 feet). Mounting it too high can make vehicles appear too small for the system to analyse.
• Downward Angle: The camera should be angled downwards to capture the side profile of a car. Avoid a top-down "bird's-eye view," as this doesn't present a recognisable vehicle shape.
• Clear Line of Sight: Ensure there are no obstructions, such as tree branches, bushes, or garden ornaments, blocking the view of your driveway or the area you want to monitor.

2. Adjust Motion Detection Zones

You need to tell the system exactly where to look for vehicles.

1. Access your DVR/NVR's main menu and navigate to the settings for the specific camera channel.
2. Find the "Motion" or "Smart Detection" settings.
3. Select the option to edit the detection area or grid.
4. Ensure that the zone you draw accurately covers the entire area where a vehicle would pass through or park. Make the zone slightly larger than the vehicle's path to ensure it's triggered as the car enters the frame.

3. Fine-Tune Sensitivity Settings

Sensitivity controls how much change in the image is needed to trigger an event. For vehicle detection, you are often adjusting the sensitivity of the AI, not just general motion.

• Start in the Middle: Set the sensitivity to a medium level first.
• Test and Adjust: Have someone drive a car through the detection zone. If it's not detected, increase the sensitivity one level at a time. If you get false alerts from shadows or other objects, decrease the sensitivity. This may require some trial and error to find the perfect balance.

4. Ensure Firmware is Up-to-Date

This is a crucial but often overlooked step. Improved detection logic is one of the most common reasons for a firmware update.

1. Connect your Swann DVR/NVR to your internet router.
2. Go to the System > Maintenance > Upgrade menu.
3. Use the "Check for Update" feature to see if a new version is available.
4. If an update is found, follow the on-screen instructions to install it.

5. Optimise Lighting Conditions

Vehicle detection can be less effective in challenging lighting.

• Night Vision: Ensure the camera's infrared (IR) LEDs are working correctly at night and are not being blocked or reflected by nearby surfaces, which can create glare.
• External Lighting: Consider adding motion-activated security lights. A well-lit area provides the camera with a much clearer image to analyse, significantly improving detection accuracy for both vehicles and people.

By carefully considering your camera's position and methodically working through the software settings, you can dramatically improve the reliability of your Swann system's vehicle detection and receive only the alerts that truly matter.
