Small Lens, Big Scene: JSD3840 in Compact Video Conferencing Terminal Design

Release time:2026/1/29 9:57:29 Article source: SHENZHEN JSD OPTOELECTRONICS CO.,LTD

Huddle rooms are getting smaller. Hardware is getting sleeker. The era of bulky, intimidating cameras is over.

Design engineers face a nightmare. You need to shrink the device. You need to expand the view. You need professional quality.

Meet the paradox breaker: the JSD3840.

This is the secret weapon for next-generation video bars and portable conference units. It packs massive optical performance into a footprint that barely exists.

The "Big Scene" Capability

"Can everyone squeeze in?" Stop asking that.

The JSD3840 throws open a wide 100° Field of View. The whole table fits. The whiteboard fits. The struggle for frame space ends here.

Wide lenses usually come with a penalty: the "fish-eye" look. That looks cheap. It ruins professional presentations.

This lens defies the norm. Distortion is less than 0.4%. Optical correction is built-in. Straight lines stay straight. The room geometry remains true. Your software saves processing power by skipping the de-warping step.

 

The "Small Lens" Form Factor

Space inside a modern chassis is expensive. Every millimeter counts.

The JSD3840 respects your PCB layout.

Thread: Standard M12. It integrates easily.

Total Track Length (TTL): A tiny 15.8mm.

It tucks neatly into slim soundbars and compact AI terminals.

Don't let the size fool you. It covers a massive 1/1.8" Image Circle. You get the light-gathering capability of a large sensor without the heavy glass.

 

Pixel-Perfect Performance

Blurry feeds kill collaboration.

This lens resolves a stunning 20MP. Digital zoom becomes a viable tool. Crop into the speaker. Zoom in on a document. The details stay crisp.

The optics are tuned for depth. With an EFL of 3.76mm and F/No 4.0, the focus is deep. The person next to the camera is sharp. The person at the back of the room is sharp. Everyone is equal in the eyes of the lens.
