The Triplett 8050 CamView W35 portable video monitor has a high-contrast, high-brightness 3.5" LCD screen that supports both Composite Video Baseband Signal (CVBS) NTSC and PAL video formats, a BNC video input jack, a built-in 1W speaker, audio input and output connections, an adjustable wrist band, a built-in stand, and a mounting thread. An active matrix thin-film transistor (TFT) provides high-contrast viewing of both CVBS National Television System Committee (NTSC) and CVBS Phase Alternating Line (PAL) video formats on the large, high-brightness, daylight-viewable LCD screen. . All video settings, such as brightness, contrast, saturation, sharpness, volume, and language, are adjusted through an on-screen menu. The menus display text in either English or Chinese. A Bayonet Neill-Concelman (BNC) cable connection (cable included) provides video input. The monitor has a built-in 1W speaker and comes with RCA audio/video input (3.5mm, 4-circuit) and output (2.5mm, 3-circuit) cables. The adjustable wrist strap allows single-handed operation of the monitor. The built-in stand provides for desktop operation or can be used as a belt clip. A female mounting thread (1/4 by 20) supports monitor connection to a tripod or bracket. Four NiMH rechargeable batteries (included) provide up to six hours of use. A standby mode automatically initiates when no video signal is present, and allows the monitor to operate on battery power for up to 12 hours. The monitor also comes with a carrying case and a storage box.
