As part of regional “Smart City” initiatives, multiple cities in Guangdong Province began building integrated smart poles combining lighting, surveillance, environment sensing, and public information display. LED screens serve as the visual core, used for broadcasting public notices, weather alerts, and civic guidance.
Technical Implementation:
● P4 outdoor waterproof LED modules installed as horizontal strip screens on the poles
● NovaStar TB2‑4G controllers selected as the unified control unit, embedded with single-mode 4G modules
● Power supplied via municipal pole electricity, regulated to 12V DC for both screen and controller
● Content managed and scheduled centrally via the VNNOX cloud platform
● Installed in high-footfall zones such as main roads, commercial streets, and park entrances
Deployment Highlights:
● Zero ground cabling; leverages existing infrastructure to shorten deployment time
● Screens automatically adjust brightness and power schedules based on ambient light and system clock
● Independent 4G networking avoids unified broadcasting across all screens—supports local customization
Performance Outcome:
Post-deployment, average manual inspection costs dropped by over 60% per area. Device uptime exceeded 98%, making the system a reliable platform for emergency broadcasting and public service messaging—now serving as a scalable model for other smart pole projects across China.
2. National Retail Chain Window Display System
Project Background:
A leading beverage chain aimed to standardize its visual communication system nationwide to improve brand visibility and foot traffic. Storefront LED displays were selected as the visual focal point, requiring centralized management, remote scheduling, and flexible deployment to adapt to different store layouts.
Technical Implementation:
● Vertical P2.5 full-color LED cabinets installed either flush-mounted or embedded within storefront windows
● TB2‑4G controllers used to standardize layout templates and playback zones
● Devices connected via in-store Wi-Fi with optional 4G as backup
● Content centrally produced by HQ marketing, edited via ViPlex Express, and pushed remotely via VNNOX
● Regional agents granted tiered access to manage local scheduling
Deployment Highlights:
● “Deploy once, zero onsite maintenance” model suits leased properties with fast tenant turnover
● Automatic day/night content switching improves visual appeal and energy efficiency
● Holiday promos, store openings, and co-branded campaigns can be mass-updated in under 10 minutes
Performance Outcome:
Post-launch, brand consistency and conversion rates improved significantly. Average foot traffic per location increased by 15% month-over-month. With local caching and offline playback, screens maintained uninterrupted operation even during network outages—enhancing brand perception and customer reach.
3. Urban Public Bus LED Advertising System
Project Background:
To boost advertising revenue, bus operators in several cities began replacing static lightboxes with dynamic LED advertising systems. LED screens were mounted on bus roofs and rear ends for displaying commercial ads, PSAs, and travel alerts.
Technical Implementation:
● Horizontal LED strip screens on bus rooftops and high-brightness full-color displays on rear panels
● TB2‑4G controllers integrated with 12V onboard power systems, ensuring stability under fluctuating voltage
● Connectivity via 4G SIM modules; GPS modules added for location-based content delivery
● Content managed through the VNNOX platform and scheduled based on location, route, and time
● All hardware ruggedized with anti-shock, weather-resistant enclosures for continuous operation
Deployment Highlights:
● Fanless controller design prevents dust buildup, extending service life
● Remote control from driver cockpit allows screen shutdown during night hours for energy savings
● Geo-triggered content playback (e.g., play shopping mall ads when entering commercial zones) enables precision advertising
Performance Outcome:
The mobile ad network enabled precise audience targeting, with each bus achieving over 20 ad cycles per day. Combined with GPS-based smart scheduling, ad ROI increased significantly—average CPM rates rose by 50%. The TB2‑4G’s stable performance has laid the foundation for large-scale deployment of mobile media platforms in the transit industry.
