How to Fix Pixelated or Blurry Video on Your Zosi Camera
A security camera is only as good as the image it produces. If the video feed from your Zosi camera is pixelated, blocky, or blurry, it can make it impossible to identify important details like faces or number plates. This issue can occur during live viewing, on recorded playback, or both, and it significantly reduces the effectiveness of your security system.
Fortunately, poor video quality is often a fixable problem related to network conditions or device settings rather than a faulty camera. This guide will help you troubleshoot the common causes of pixelation and restore a clear, sharp image.
## What Does Pixelated Video Look Like?
You're dealing with a video quality issue if you notice:
- Blocky Images: The video looks like it's made of large, chunky squares, especially during movement.
- Blurriness: Fine details are lost, and the entire image appears soft or out of focus.
- Lagging or Freezing: The video stream stutters, freezes, and then jumps forward.
- Low Resolution: The image looks like a low-quality video from the early days of the internet, even though you bought an HD camera.
- Poor Night Vision: The image at night is excessively grainy or unclear.
- Difference in Quality: The video looks clear on one device (e.g., your NVR monitor) but is pixelated on your phone.
## Solutions for Fixing Zosi's Pixelated Video
Let's work through the most likely causes, from the simplest to the more complex.
### 1. Check Your Camera's Stream Settings
Your Zosi camera produces multiple video streams, typically a high-quality 'Mainstream' for recording and a lower-quality 'Substream' for remote viewing on mobile apps. If you're viewing the Substream, the quality will be inherently lower.
- In the Zosi Smart App: When viewing a single camera, you should see an 'HD' or 'SD' button. 'HD' (High Definition) selects the Mainstream, while 'SD' (Standard Definition) selects the Substream. Make sure you have 'HD' selected for the best quality.
- In the NVR/DVR Interface: Navigate to the camera setup or recording settings. Ensure that the 'Encode' or 'Video Quality' settings for the Mainstream are set to the camera's highest resolution (e.g., 1080p, 5MP) and a reasonable bitrate.
### 2. Improve the Network Connection
This is the most common cause of pixelation, especially for Wi-Fi cameras. A weak or unstable network connection forces the camera to compress the video file heavily, sacrificing quality to transmit the signal.

For Wi-Fi Cameras:
- Check Signal Strength: How far is the camera from your Wi-Fi router? Walls and floors can significantly weaken the signal. Try temporarily moving the camera closer to the router to see if the image quality improves.
- Use a Wi-Fi Extender: If the camera must be located far from the router, install a Wi-Fi range extender to boost the signal in that area.
- Reduce Network Congestion: If many other devices are using your Wi-Fi (e.g., streaming movies, online gaming), it can reduce the bandwidth available for your camera.
-
For Wired (PoE) Cameras:
- Inspect the Ethernet Cable: Check the cable for any physical damage, kinks, or loose connectors. A damaged cable can lead to data loss and a poor-quality video stream. Try a different Ethernet cable to rule out a fault.
### 3. Clean the Camera Lens
It might sound simple, but a dirty or smudged lens is a frequent cause of blurry or hazy video.
- Wipe it Clean: Use a soft, clean microfibre cloth to gently wipe the camera's lens dome. Avoid using abrasive paper towels or harsh chemical cleaners, as they can scratch the surface.
- Check for Condensation: In some weather conditions, moisture can get trapped inside the camera housing, causing a foggy image. If this happens, you may need to bring the camera indoors to dry out.
### 4. Update Camera Firmware
Ensure your camera and NVR/DVR are running the latest firmware. Manufacturers often release updates that include improvements to video encoding and performance, which can help resolve quality issues. Check for firmware updates within the Zosi app or on the Zosi support website.
