The Small Body Camera That Makes A Big Difference

Studies show that when people can see they are being recorded it can help calm them down and avoid conflict, and that’s just what Calla does by de-escalating situations, reducing disruption and recording an independent account of what happened.

Front Facing Screen

This signature Reveal feature has a proven calming effect on those being recorded while maximising transparency with the public. It protects those on both sides of the lens.

Unbreakable Security

Calla captures the truth, and that footage is AES 256-bit encrypted at the point of capture and remains encrypted through the upload process to DEMS 360.

How can Calla help?

When people see themselves being recorded on Calla’s front-facing screen, they tend to calm down.

But if a situation does escalate, the user has the confidence that there is a complete recording of the incident showing an independent account of events. Therefore, the camera isn’t recording all the time, only when the user deems it necessary - in line with agreed policies.
