Lorex Camera: Fixing a Purple Stripe on the Video Feed

Troubleshoot a purple stripe on your Lorex security camera video. Diagnostic steps, solutions, and prevention tips for Canadian homes. Ensure reliable security.

Frequently Asked Questions

•How do I perform a factory reset on my Lorex camera?

The process varies by model. Consult the Lorex support website for your specific camera, but generally involves holding down a reset button for 10-15 seconds while the camera is powered on. Then, re-pair with the app.

•What is the warranty period for Lorex cameras in Canada?

Warranty periods vary, but are often 1-2 years. Refer to your purchase documentation or the Lorex website for details on your specific model. Keep your proof of purchase!

•How can I improve my Wi-Fi signal strength to my Lorex camera?

Consider moving your Wi-Fi router closer to the camera, using a Wi-Fi extender, or switching to a less congested Wi-Fi channel. Ensure the antenna on the camera is properly oriented. Bell Giga Hub users should ensure band steering is optimized.

Safety Warning:

Do not attempt to disassemble the camera. This will void the warranty and may expose you to electrical hazards. Lithium-ion batteries can pose a fire risk if punctured or mishandled. Dispose of damaged or end-of-life batteries properly at designated recycling centers.

Why This Happens:

CMOS image sensor failure or degradation.
Faulty ribbon cable connecting the image sensor.
Firmware corruption affecting image processing algorithms.
Overheating of the camera's internal components due to prolonged exposure to direct sunlight (summer months).
Electromagnetic interference (EMI) from nearby devices (e.g., microwave ovens, cordless phones operating on 2.4GHz).
Water ingress causing corrosion on the image sensor or related components.

Symptoms:

Display exhibits a consistent purple vertical stripe on the right side of the video feed. This is observed both in live view and recorded footage via the Lorex Home app (Android/iOS) using a Bell Giga Hub internet connection. No error messages are displayed in the app. The camera's LED indicator displays solid blue indicating a stable network connection. Rebooting the camera does not resolve the issue.

Technical Recommendation:

If the purple stripe appears only during nighttime recording, it may be related to the IR illumination. Try disabling and re-enabling the IR LEDs in the camera settings within the Lorex Home app.

Solution:

1

Power cycle the camera: Disconnect the camera from its power source (AC adapter) for at least 60 seconds and then reconnect. This performs a hard reset.
2

Check the camera's firmware version: Using the Lorex Home app, navigate to the camera settings and verify that the device is running the latest firmware. If not, initiate a firmware update (OTA).
3

Rule out Wi-Fi interference: Use a Wi-Fi analyzer app (available on Android and iOS) to assess the 2.4GHz channel congestion in the vicinity of the camera. Switch the camera's Wi-Fi channel to a less congested one via the Lorex Home app, if possible. Rogers Ignite users may need to access their modem settings to optimize channel selection.
4

Inspect the camera lens: Carefully examine the lens for any dirt, smudges, or obstructions. Clean the lens with a soft, lint-free cloth.
5

Factory Reset: If issues persist, perform a factory reset. Note that a factory reset will erase all customized settings, requiring re-pairing with your Lorex account.
6

Contact Lorex Support: If the problem persists after these steps, contact Lorex customer support for warranty service or repair options. Provide them with the camera's model number, serial number, and a detailed description of the issue, including screenshots or video recordings.
7

Environmental assessment: Rule out condensation. Bring the camera indoors for 24 hrs to see if it resolves, particularly if cold weather is suspected.

Technical Overview:

The camera captures video using a CMOS image sensor. The purple stripe likely originates from a defect or malfunction within the sensor's pixel array or its associated processing circuitry. Alternatively, a damaged ribbon cable connecting the sensor to the mainboard could introduce artifacts. Video data is encoded (likely H.264 or H.265) and transmitted wirelessly via 2.4GHz Wi-Fi. Signal strength (RSSI) is typically -65dBm at the camera location.

Preventative Care:

Regularly check for firmware updates through the Lorex Home app and install them promptly. Ensure a stable internet connection during the update process (Rogers or Bell).
Clean the camera lens periodically with a soft, lint-free cloth.
Monitor the camera's operating temperature and avoid exposing it to extreme heat or cold.
Consider using a surge protector to protect the camera from power surges, especially during thunderstorms.
Implement a scheduled reboot of your router/modem every month.
