NAB 2015: Bradley Engineering unveiled the finished version of a small, remote controlled 4K camera for high end broadcast applications at NAB.
The camera is the result of a collaboration between Bradley, JVC Kenwood and AltaSens, which is a wholly-owned subsidiary of JVC Kenwood.
It features the same 4K AltaSens Super 35 CMOS sensor that is used in the JVC GY-LS300 camera and has a Micro Four Thirds lens interface which offers adaptors for B4 and PL mounts. MFT Zoom servo lenses are available and can be added.
The output is by fibre from the camera.
The Bradley Base Station provides a Genlock input, a TTL level control protocol and a dual ST fibre connection to distances up to 20 kilometres which includes full control and genlock.
Bradley accessories include a dedicated pan/tilt unit, three options for remote camera panels with full CCU control, a fibre base station with SMPTE hybrid options or ST connectors, remote control via fibre, SMPTE Adaptors, zoom servo lenses and lens servos.
Bradley Engineering founder David Bradley said: “The collaboration behind this project has been amazing, with engineers from all three companies, working together as a single team.
“The result is a true remote camera with outstanding picture quality and few compromises.
“There is no need for fibre converters, and with the native option of using MFT lenses the cost of a fully working system can be kept within reasonable 4K budgets.
AltaSens VP of business development and compliance Darren Paulson added: “Bradley Engineering is the ideal company to advise us regarding key design aspects and to subsequently deliver a superb integrated solution for 4K cinema or UHD broadcast, or even for sports broadcast where slow-motion playback is required.
“In addition, the sensor’s extensive programmability enables extremely fast frame rates in many optical formats, creating additional uses for this technology in scientific, military and consumer markets.”
