CCTV monitors are displays built for continuous surveillance viewing, where the signal often arrives over BNC connections from cameras and recorders. The evidenced product page in this family is the BNC CCTV monitor, model ZC220, a 21.5 inch display with 1920 by 1080 resolution and D-SUB, DVI, VGA, BNC and HDMI interfaces, and a brightness of 350 candela per square metre. That page is the only place where a CCTV model is given a specification table, and the model ZC120 seen in an index listing is a different model and is not mixed into the ZC220 page.
Buyers of CCTV monitors usually check the input set first, because a monitor that lacks BNC input cannot take a direct camera feed without an adapter. They also check size against viewing distance: a single monitoring post suits a smaller display, while a wall of feeds suits larger displays or several displays side by side. The security and surveillance application pages and the BNC input guide explain those choices in more detail.
The company's CCTV line spans a wider size range in its category listing, but only the ZC220 has a recorded detailed specification here. Larger or smaller CCTV displays are described only as family options on this page. A buyer who needs a size other than 21.5 inches, or a particular mounting or power arrangement, should state it in an enquiry so the company can confirm a matching model.
Order quantity and lead time are confirmed per model in enquiry, and prices are not published on this site.
