A Comprehensive Guide to Fixing Mobotix Poor Video Quality
Mobotix cameras are high-performance, decentralised surveillance systems. However, even these premium devices can sometimes produce video that is blurry, pixelated, or choppy. If you're not getting the crisp image quality you expect, this guide will walk you through the key areas to check, from network configuration to the camera's unique image settings.
Let's dive into the professional steps to diagnose and solve video quality issues on your Mobotix camera.
Step 1: Assess Network Performance
The decentralised architecture of Mobotix cameras means each camera acts as its own server. This makes a stable network connection absolutely critical for good video performance.
Bandwidth is Key
- Sufficient Upload Speed: Each camera needs a stable slice of your network's upload bandwidth. High-resolution streams can be demanding. Use a network performance tool to ensure there are no significant packet loss or latency issues between the camera and the viewing station.
- Avoid Network Bottlenecks: Heavy traffic from other devices can degrade your camera's stream. For critical installations, consider placing cameras on a separate VLAN (Virtual LAN) to isolate their traffic from general network data, ensuring they always have the bandwidth they need.
Connection Stability
- Wired Connection: For a system like Mobotix, a wired Ethernet connection is strongly recommended over Wi-Fi. It provides the stability and consistent throughput required for high-quality video.
- Cabling Quality: Ensure you are using high-quality network cables (Cat5e or better). A faulty cable or connector can be a hidden cause of poor video performance.
Step 2: Optimise Mobotix Image and Video Settings
Mobotix cameras offer deep customisation of the video stream. Let's explore the most important settings.
Image Sensor Control
Access the Setup Menu and go to Image Sensor Control.
- Exposure Control: The camera needs to be correctly configured for the lighting conditions. You can choose from various exposure programs. If your image is too dark or washed out, experimenting with different exposure settings is the first step.
- Sharpness: This setting can enhance the definition of edges in the image. Be careful not to set it too high, as it can create an artificial look and introduce digital noise. A small, incremental increase is best.
- Resolution: In the General Image Settings, confirm that you are using an appropriate resolution for your needs. Using the highest resolution isn't always necessary and will consume the most bandwidth.
MxPEG Video Settings
Mobotix uses its own efficient codec, MxPEG.
- Quality/Bitrate Control: In the MxPEG Video Settings, you will find a Quality slider. Increasing this will improve image detail at the cost of higher bandwidth. Find the sweet spot where the quality is acceptable and the stream is stable on your network.
- Frame Rate: The frame rate is set within the Recording settings. A higher frame rate creates smoother video but, again, requires more network and storage resources. Adjust this based on the level of motion in the scene.
Step 3: Check the Lens and Physical Setup
The physical state of the camera is just as important as its software configuration.
- Lens Focus: Many Mobotix models have a manually adjustable lens. If the image is uniformly blurry, the lens may have been vibrated out of focus over time. You will need to physically access the camera, loosen the lens lock, and carefully adjust the focus while watching the live feed until it is perfectly sharp.
- Clean the Dome/Lens Cover: The transparent cover over the lens can accumulate dust and grime, especially outdoors. This will cause the image to look hazy or unfocused. Regularly clean it with a lint-free cloth to maintain optimal clarity.
- Lighting Conditions: Is there enough light in the scene? While Mobotix cameras have excellent low-light performance, no camera can produce a clear image in complete darkness without adequate infrared (IR) illumination. Ensure external illuminators are working and positioned correctly.
By methodically reviewing your network, optimising the powerful internal settings, and ensuring the camera's physical condition is optimal, you can resolve most video quality issues and restore the high-end performance expected from a Mobotix system.
