Rear view of CV503
The Marshall CV503 Full-HD Miniature Camera offers performance, flexibility, and value in a tiny form factor. Built around a next generation 2.5-Megapixel, 1/2.86-inch sensor, the CV503 delivers ultra-crisp, clear progressive Full-HD video up to 1920x1080p at 60/59/50fps and interlaced 1920x1080i at 59.94/50fps.
The CV503 utilizes a full-sized BNC (3G/HDSDI) output on rear panel and locking I/O connection for power, control, and stereo audio input (embedded on 3G-SDI output). The CV503's threaded M12 lens mount offers a wide range of prime and varifocal lens options.
The CV503 can capture detailed shots while maintaining an ultra-discreet miniature point-of-view perspective without sacrificing versatility or convenience. Remote adjustment and picture settings commands are delivered via common RS485 (Visca) or OSD menu joystick on locking breakout cable. A wide range of picture adjustment settings are available and adjustable from a distance including paint (red/blue), white balance, exposure, gain control, pedestal (blacks), white clip, gamma, and more.
