Every gram counts. Officers carry radios, armor, weapons, and tools. Gear weight equals fatigue. The camera on their chest or in their hand should be a witness, not a burden. Heavy, bulky optics are a thing of the past.

The JSD3840 changes the math.

This is not a lens for vacation selfies. It is a precision tool engineered for high-stakes environments. It brings professional optical performance to the most compact handheld enforcement devices.

1. Shed the Bulk: 15.8mm TTL

Space is luxury. Designers of body cams fight for every millimeter. The JSD3840 wins this fight.

With a Total Track Length (TTL) of just 15.8mm, it sits flush. It allows for slimmer device profiles. It leaves room for larger batteries. The standard M12 Thread ensures compatibility with rugged industrial housings. It is small. It is tough. It disappears into the gear until it is needed.

2. Evidence Needs Truth: <0.4% Distortion

Wide angles usually bend reality. A straight door frame looks curved. A suspect’s height gets warped. In legal situations, visual accuracy is paramount.

The JSD3840 offers a 100° Field of View. It captures the periphery. It captures the context. Crucially, Distortion is <0.4%. The image remains flat and true. No fish-eye effects. No warped edges. What you see on the screen is exactly what happened in the field.

3. Forensic Clarity: 20MP Resolution

Grainy footage creates doubt. Sharp footage solves cases.

This lens resolves 20 Megapixels. It captures license plates, badge numbers, and facial features with absolute precision. It supports a large 1/1.8" Image Circle. Big sensors gather more data. The lens feeds that sensor perfectly.

4. Reliable Focus

Autofocus systems hunt. They break. They fail in low contrast.

The JSD3840 utilizes a fixed F/NO 4.0 aperture. This provides a deep depth of field. The subject stands three feet away or thirty feet away; they are sharp. No motor noise. No delay. Just instant, clear recording.
