Blurry footage is useless.

Grainy faces solve no crimes.

Modern security demands more. You are upgrading to 4K sensors. You are looking at 8K systems.

Don't put cheap glass on expensive sensors.

The bottleneck is the lens. The solution is the JSD3840.

 

Feed the Beast: 1/1.8" Large Format

Old M12 lenses are tiny. They choke modern sensors.

The JSD3840 is different. It covers a 1/1.8" image circle.

It captures more light. It feeds more data to the sensor. Night vision gets clearer. Shadows reveal secrets.

 

20MP: Beyond 4K

High-definition is the new standard.

Most lenses stop at 5MP or 8MP. We went further.

20 Megapixels.

Zoom in. The license plate is readable. The facial features are distinct.

Your 4K stream looks sharp. Your 8K setup finally has a lens that can keep up.

 

Wide Angle, Zero Confusion

Monitor a whole parking lot. Watch an entire warehouse floor.

FOV: 100°.

See it all.

Usually, wide angles warp reality. Door frames bend. People look stretched.

Distortion: <0.4%.

This is optical precision. The image is flat. The geometry is true. AI recognition software works better. False alarms go down.

 

Discreet and Powerful

Big performance usually means big barrels. Not here.

Thread: Standard M12.

TTL: Just 15.8mm.

EFL: 3.76mm.

Fit it into compact dome cameras. Hide it in discreet units. The lens stays small. The image stays huge.

The Professional Standard

 

Clarity creates safety.

See the truth. Install the JSD3840.
