Solving Blurry Video Issues on Your Comelit Intercom System
A Comelit video intercom system is a key part of your home or building's security, providing a clear view of your entrance. When that view becomes blurry, fuzzy, or out of focus, it can be both frustrating and concerning. A sharp image is essential for identifying visitors properly.
This guide provides a structured approach to troubleshooting and fixing the most common causes of blurry video on Comelit systems.
Step 1: Start with a Physical Inspection of the Outdoor Unit
More often than not, the cause of a blurry image is something simple on the exterior of the door station.
-
Clean the Camera Lens: The lens is exposed to the environment and can easily get dirty.
- Action: Take a soft, lint-free microfibre cloth and gently wipe the camera lens. This will remove dust, smudges, and water spots that can obscure the view.
- Tip: For stubborn dirt, you can slightly dampen the cloth with water. Avoid spraying any liquids directly on the unit.
-
Check for Moisture: Condensation can form behind the lens cover, especially in humid weather or when the temperature changes quickly.
- Symptom: The image will look foggy or hazy.
- Action: This issue often resolves itself as the humidity level drops. If it happens frequently, it may indicate that the unit's weatherproofing seal has been damaged, which would require professional attention.
-
Look for Scratches: Inspect the lens cover for any scratches or scuffs. A damaged lens cover can permanently distort the image and may need to be replaced.
Step 2: Examine Your Indoor Monitor's Settings
An incorrect setting on your indoor unit can sometimes affect the perceived quality of the image.
- Check Display Settings: Navigate to the settings menu on your Comelit monitor. Look for display options like Brightness, Contrast, and Colour.
- Action: If these settings are improperly configured (e.g., contrast is too low), it can make the image appear soft and unfocused. Try adjusting them or resetting the display settings to their factory defaults to see if it improves the picture clarity.
Step 3: Investigate the System's Wiring
The video signal is transmitted through wires from the outdoor station to your indoor monitor. A problem with this wiring can degrade the signal.
- Secure the Connections: Check that the wiring is securely connected to the terminals on the back of the indoor monitor and at the outdoor panel. A loose wire can cause an intermittent or poor-quality signal.
- Inspect for Damage: If any part of the wiring is accessible, check it for any signs of physical damage, such as cuts, frays, or sharp bends.
- Confirm Correct Cable Type: Comelit systems require specific types of cabling for optimal performance. If the wrong type of wire was used during installation, or if the cable run is longer than the recommended maximum distance, signal loss can occur, leading to a blurry image.
When Further Assistance is Required
If you have performed all the checks above and the video feed from your Comelit intercom is still not clear, there might be an underlying hardware issue. This could be a fault with the camera module in the door station or with the screen on the indoor monitor.
At this stage, it is advisable to contact a professional installer or a certified Comelit technician. They possess the specialised tools and knowledge to diagnose the system's internal components and resolve the issue effectively.
