The Weisscam Company was founded by Director of Photography (DoP) Stefan Weiss.
History
In 2005, WEISSCAM began developing the first prototype of the HS-1 camera for international commercials. After high-speed shoots with the prototype, WEISSCAM collaborated with
P+S Technik to launch a redesigned camera in 2006–2007. Subsequently, from 2007 to 2008, WEISSCAM expanded their product line by developing the HS-2 Camera, DM-2 Digimag, DBB Debayerbox, and HU-2 Handunit, aiming to create a standalone camera capable of working in both HD SDI and RAW formats.

up to 1000 frame/s are possible. Maximum resolution of the HS-1 model is 1280 x 1024 pixel.
; Hand Unit
With the Hand Unit most important recording features of the camera can be remote controlled: START/STOP, frame rate adjustment, frame rate ramp settings, frame rate jumps. The ergonomic design allows comfortable one hand use to start and stop recording. With the well fitted hand wheel the frame rate can be changed smoothly while recording.

WEISSCAM HS-2
The equipment of the digital high-speed camera WEISSCAM HS-2 manufactured by
P+S Technik includes the camera HS-2, the WEISSCAM Digimag DM-2, the WEISSCAM Debayberbox DBB and the WEISSCAM Hand Unit HU-2.
;Camera
The WEISSCAM HS-2 is developed as a stand-alone camera targeted toward the needs of cinematographers.
The HS-2 has a full format Super35 CMOS sensor with a global shutter. By using the Interchangeable Mount System (IMS) you can attach nearly every lens on the camera (PL Mount,

The output of the WEISSCAM HS-2 offers two streams at the same time and uses the HD SDI interface for both signals. With the WEISSCAM "RAW IN HD SDI" mapping, you are able to transport the RAW files via the worldwide standard and fast HD SDI single and
dual link interface.

With the WEISSCAM HS-2 there are 2000 frame/s in full HD possible. To record more speed one needs to reduce the recorded resolution on the sensor. For example, in 720p one can record up to 4000 frame/s with the WEISSCAM HS-2.

; Digimag DM-2
The WEISSCAM DIGIMAG DM-2 is an uncompressed and extremely compact HD-SDI single and dual link recorder, which has the uniqueness of recording either YCbCr/ RGB streams or RAW data.
The RAW data are stored by using the WEISSCAM "RAW in HD SDI" mapping, which allows you to map up to two RAW images in one HD SDI frame and therefore download for example 100 RAW file in 1080p 50 mode.
There is the possibility to record other cameras signals like ARRIFLEX D20/21, Sony F35, GrassValley Viper, Phantom HD and Standart HDTV (like Sony F900).
For downloading the files you can either use the HD SDI single and dual link output but also the IT interfaces like
Fire wire.
In conjunction with the external WEISSCAM DEBAYERBOX DBB, you are able to do a realtime debayering of the stored RAW data on the DIGIMAG DM-2. You can offer the post house immediately a standard HD YCbC.
; Debayerbox DBB
The WEISSCAM DEBAYERBOX is a realtime hardware debayerer with newest FPGA technology and sophisticated color algorithm. All WEISSCAM RAW formats can be converted into HD SDI YCbCr 4:2:2 single or dual link by just connecting the RAW Input with the HD SDI Output. For the debayering you can choose between 16 different curves from lin to log.
