# Camera is not in focus

### Symptoms

- Output of a camera is **blurred** in LATRAS Hub
- I can't get camera into focus
- Even after adjusting the focus ring on the lens camera is **not in focus**

### Before troubleshooting

- **Remove optical filter** from the lens.
- Ensure that the <span style="color: rgb(241, 196, 15);">camera is properly connected </span>to the computer through USB3 port.
- Start the camera in LATRAS Hub and enable <span style="color: rgb(241, 196, 15);">Preview.</span>
- Set <span style="color: rgb(241, 196, 15);">camera gain</span> so that the camera has <span style="color: rgb(241, 196, 15);">visible output.</span>
- Now, you should see camera **output in a large window.**
- Do not focus in darkness. It will be way easier to get camera into focus with indoor light.

### Resolution

1. <span style="color: rgb(241, 196, 15);">Rotate with the focus ring</span> on the lens. This will change the camera's focus. Look at the <span style="color: rgb(241, 196, 15);">main view in LATRAS HUB</span>, the focus **change should be visible there right away**.
2. Check if the lens is **clean**.
3. Check if the lens is <span style="color: rgb(241, 196, 15);">properly threaded into the camera</span>. If not, thread it back in and go to step 1.
4. Take the camera and <span style="color: rgb(241, 196, 15);">try focusing on everyday objects</span>. Focusing against a white wall or a projection screen **can be very tricky**. If you manage to get into focus **try it again with your projection**.
