The ZKDigimax DG03-A4W22 AI wall-mounted digital signage display combines a 21.5-inch Full HD screen, Android 12 and an integrated 5 MP AI camera for measurable, more targeted customer communications.
The ZKDigimax DG03-A4W22 AI wall-mounted digital signage display is a compact 21.5-inch Full HD screen designed for locations where advertising, visitor information and customer engagement need to work together. It combines a professional wall-mounted display with an integrated 5 MP AI camera, allowing a well-planned deployment to deliver multimedia content while also supporting audience measurement and people-counting functions.
This makes the DG03-A4W22 a strong fit for supermarkets, retail stores, airports and other public-facing indoor locations. Rather than relying on static posters alone, organisations can present campaign content, service messages and promotional media on a display that has been designed to support better-informed content decisions. The compact 305 × 531.6 × 30 mm enclosure is practical where a floorstanding display is not appropriate.
The integrated 5 MP AI camera supports face recognition, people counting and demographic analysis functions for gender and age. These capabilities can provide data that helps organisations understand audience patterns and plan content more accurately for the intended customer groups. They are not a substitute for a responsible privacy programme: any deployment using camera, face-recognition or demographic functions must be designed around the organisation’s legal obligations, consent approach and data-governance requirements.
The display runs Android 12 on an RK3588 chipset with a quad-core Cortex-A76 plus quad-core Cortex-A55 processor, 4 GB RAM and 64 GB ROM. That platform gives the DG03-A4W22 the processing capacity required for its digital signage and integrated AI-camera role, while the 1920 × 1080 display delivers Full HD content in a 16:9 format.
The 21.5-inch ELED display is specified with 320 cd/m² typical brightness, 1000:1 contrast, 60 Hz frequency, 8 ms response time and 178° horizontal and vertical viewing angles. It displays 16.7 million colours and supports common video, audio and image formats, including H.264, MPEG2, MPEG4, H.265, MP3, WAV, JPG, BMP and PNG. This gives content teams practical flexibility for advertisements, promotional video, product messages, service updates and wayfinding content.
For installation and content delivery, the unit provides Wi-Fi supporting 802.11 b/g/n protocols and wired LAN through RJ45. Connections include RJ45, USB 3.0, USB 2.0 and HDMI input. The unit is wall-mountable and includes a 5 W-per-channel speaker specification for audio-enabled content where this is appropriate for the site.
The DG03-A4W22 is compatible with ZKDigimax ScreenDirect CMS, allowing content to be organised and managed as part of a centralised signage deployment. NZTeco can help scope ScreenDirect CMS, the network connection, content schedule and the AI-camera functions that suit the specific installation. This matters because an effective deployment needs the technical system, on-screen content and privacy approach to work together.
Designed for continuous 24/7 operation, the product has a stated 50,000-hour MTBF and operates from 0°C to 40°C with 10% to 85% relative humidity. Maximum consumption is below 120 W.

Position the display where visitors can comfortably see the content and where the camera function, if enabled, is appropriately signposted and governed. A clear visual message, sound installation method and suitable connectivity are just as important as the screen itself. NZTeco can help align the wall location, content plan and device configuration with the intended customer journey.
