# FAQ

#### Does Cyclops have MIPI CSI-2 support? — Camera interface

Cyclops doesn't have built in MIPI support; however, we have docs on how to create your own custom camera publisher. Check out [Custom camera publisher](/cyclops/developers/custom-camera-publisher.md) for details.

There a corresponding repo here: <https://github.com/Theseus-Dev/cyclops-camera-publisher>

#### **Are there any rolling shutter limitations?**

We have primarily tested on global shutter so far. We should be able to use rolling shutter, as long as the framerate is high. If the image has too much "Jell-O" distortion that will be a problem; but if the framerate is high and image quality is good some jitter is okay. We can support low quality images.

#### **What camera FOV / lenses work with Cyclops?**

This depends on mission altitude. We are using anything from 60deg to 100+deg. Any standard FPV camera & lens should work; we like to use whatever is cheapest and most available.

#### **Does Cyclops support thermal cameras for night operations?**

We see the same performance between thermal & EO cameras. We have used a CADDX Eclipse o3 through an analog to digital converter (ADC) which is also 256 pixels with nominal performance at 120m AGL.

#### **What is the operational envelope?**

EO Cameras: Any 1280x720p EO camera will be good for 60-1000m AGL out of the box. We have seen good performance above this range, but our testing is somewhat limited by US airspace regulations.

Thermals: We need to test 256 maximum altitude. We are able to fly it at 60-120m AGL with our airspace here, but Cyclops should be able to go higher. We have flown 640 cameras up to 2500m, with performance degrading around 1500m AGL

#### **Module operation without M.2 HAT**

M.2 drives offer much faster read/write speeds, more storage, and more reliability, but at a cost comparable to the Cyclops BOM. For that reason, micro SD cards have quickly become our preferred method for setting up Cyclops.

**Micro SD cards are supported for use with cyclops**, however, they come with an important caveat:

* Smaller SD cards will quickly fill with log data and must be manually cleared to ensure normal operation. [Recording control](/vozilla-gcs-software/vozilla-app/settings/recording-control.md#clearing-log-data)
