UHL-F4000
4K/HD Multi-Purpose Camera
The UHL-F4000 is a 4K/HD 3CMOS Multi-Purpose separate optics 2-piece camera, featuring a compact, lightweight, and low power consuming camera head (optical block), which makes the camera especially well suited for helicopter camera applications. As the succeeding model of the HDL-F3000, the F4000 is newly equipped with Global Shutter CMOS sensors, which capture natural images completely clear of geometric distortion during still frame analysis and flash band effects. The F4000 is also newly capable of outputting 4K and Cutout HD images, but its significant low light capability has been passed down from its former model. Additional improvements in its image processing functions such as Variable Contrast Control, Image Sharpening Function, and Digital Zoom Function (from 1.1x to 10.0x) will broaden the F4000’s usage.
Newly Developed Global Shutter CMOS Sensor
A newly developed 2/3-inch CMOS sensor provides a sensitivity of F13 (2160 / 50p) / F12 (2160 / 59.94p) in 4K. The imager incorporates a global shutter pixel architecture, enabling the camera to capture natural images without geometric distortion even under challenging situations.
Compact Size
A compact and power saving camera head has been achieved in order to suit its application as a helicopter camera system. The 1.1kg camera head fits in small sized gimbals for example.
HD CUTOUT Function
By cutting out an HD image from a 4K image, two videos with different angle of 0.1, allowing a very smooth and natural zoom. Combined with the optical zoom, the overall zooming of the image looks more natural.
Digital Zoom Function
The UHL-F4000 has a digital zoom function from 1.1x to 10.0x in increments of 0.1, allowing a very smooth and natural zoom.
Combined with the optical zoom, the overall zooming of the image looks more natural. 
Quality Picture Under Any Condition
High Sensitivity
There is virtually no loss of quality caused by the difference in illumination, it can produce high quality pictures under any conditions, day or night.
Clear Image Functions
The realtime image enhancement functions clarify the images, making them ideal for surveillance and law enforcement applications.
- Contour Enhancement
- Haze Removal
- Backlight Compensation
Variable NR Control
The remote control panel includes a variable control so the operator can adapt the camera in real time for optimum noise reduction when shooting at night with high gain.
Other Features
Optical Fiber Connection
An Optical Fiber connection is employed between the camera head and CCU, allowing them to be separated by a distance up to 10km. This allows different configuration for a range of applications. * The camera head needs a connection for power (in addition to the fiber connection).
Focus Assist Function
To assist in critically focusing 4K images using an HD monitor, the contour extracted from the 4K image can be overlaid on the HD MON video.
Image Reversal Function
The UHL-F4000 can output an up-down reversed image, which is applicable if the camera is set upside down.
OVC (Optical Vignetting Correction)
When shooting under the low light situation, it is crucial to deal with a roll-off around the edges of the image and a ramping, or F-drop, a decline of overall sensitivity at the tele end of a zoom lens. The UHL-F4000 communicates with compatible lenses of the correction data and automatically compensates for the visible changes in the picture.
*with supported lenses.
