This product page covers the company's CCTV monitor, model ZC220. It is a 21.5 inch display with 1920 by 1080 resolution, a black finish, and D-SUB, DVI, VGA, BNC and HDMI interfaces. Its recorded display figures are a viewing area of 477.5 by 268.5 millimetres, horizontal viewing angle of 176 degrees and vertical viewing angle of 170 degrees, a dot pitch of 0.297 millimetres, 16.7 million colours, a brightness of 350 candela per square metre, a 5 millisecond response and a 1000 to 1 contrast ratio. Those are the specifications recorded for this model, and they are not transferred to any other product on this site.
BNC input is the feature that defines this model for surveillance buyers. Cameras and recorders in many existing installations output over BNC, so a monitor with a BNC input can take a direct feed without an adapter or converter. The additional D-SUB, DVI, VGA and HDMI interfaces let the same display also take a computer or recorder output, which suits a monitoring post that must switch between a camera feed and a system screen.
A different model, ZC120, was seen in an index listing for a 12 inch BNC input LCD CCTV display. That model is not this model, and none of its figures are used on this page. A buyer who needs a 12 inch CCTV display should enquire about it separately rather than assuming the ZC220 figures apply.
The product listing for this model names Shenzhen, China as the place of origin and OEM or ZWBA as the brand, and it names CE and RoHS among the product certifications. Certification on this site is described only in the company's own terms, and certificates are available upon request.

This model suits security viewing rooms, reception monitoring posts, small retail back offices and any post where a BNC camera feed must be viewed directly. It is not a gaming display and not a portable display, and its brightness and viewing angle figures belong to this model only.
To enquire, state the model, the input set required and the quantity. The source listing for this model notes a minimum order quantity of 2 pieces and a delivery time of 2 to 8 working days; those figures are listing terms for this model only, not a company-wide policy, and current terms should be confirmed in enquiry. Prices are not published on this site.
Installation and care notes
Install this surveillance display where the operator sits at a comfortable viewing distance for a 21.5 inch screen, with the brightness suited to the room. Connect the BNC feed directly for analogue cameras, and use the HDMI or VGA input for a recorder or computer output, checking that the recorder's output resolution matches what the display accepts.
Keep the screen clean with a soft dry cloth, and keep ventilation around the display clear, because a surveillance display may run for long hours. If a feed looks missing or distorted, check the cable, the camera or recorder output, and the input selection on the display in that order, because most surveillance display faults trace to the feed or the input choice rather than to the panel.
- Confirm in enquiry: feed types and recorder outputs for the post
- Confirm in enquiry: number of feeds and viewing distance
- Confirm in enquiry: current order quantity and lead time for that model
- Ask for: the model's specification sheet before ordering
