Application and precautions of outdoor advertising machines

Outdoor advertising displays are digital multimedia devices that integrate a display screen (such as an LCD or LED), a computer system, a network 

communication module, and a specialized housing. They have gradually replaced traditional static billboards and become a vital vehicle for urban

commercial promotion and information dissemination.

I. Core Application Scenarios of Outdoor Advertising Displays

The dynamic, high-definition, and remotely manageable features of outdoor advertising displays make them extremely useful in the following scenarios:

1. Commercial and Retail:

· Malls/Shopping Centers: Used for displaying promotional information, brand advertisements, shopping guides, and event announcements.

· Commercial Streets: Set up on street corners or in plazas, these displays broadcast commercials and enhance brand image.

· Chain Stores: Used as window displays or in-store displays to showcase product details and latest offers.

2. Public Transportation and Hubs:

· Subway/Bus Stations: Provide passengers with waiting information, commercial advertisements, news updates, and public service announcements.

· Airports/Train Stations: Used for flight/train schedules, commercial advertisements, and hotel and travel services. Taxi roofs/bus bodies: Serving as

mobile advertising platforms, covering major urban arteries.

3. Office Buildings and Communities:

· Office building lobbies/elevator halls: Targeting the professional community, displaying building information, commercial advertisements, financial

products, etc.

· High-end residential communities: Used for property management notices, community announcements, and promotion of surrounding businesses.

4. Culture, Tourism, and Public Services:

· Tourist attractions/parks: Displaying scenic area maps, cultural history, visitor information, and safety warnings.

· Museums/exhibition halls: Supplementing exhibits with promotional videos and guides.

· Government agencies/hospitals: Used for policy promotion, process guidance, expert introductions, and health education.

5. Dining and Entertainment:

· Restaurant/café entrances: Dynamically displaying menus and discounted packages to attract customers.

· Cinemas/theaters: Rotating movie trailers, show information, and ticket QR codes.

II. Core Advantages of Using Outdoor Advertising Screens

· Dynamic Attraction and Strong Visual Impact: Multi-format content, such as videos, animations, and photo carousels, attracts pedestrians' attention

more effectively than static posters.

· Flexible Content and Real-Time Updates: Through a backend management system, content can be updated consistently across all devices at any time,

meeting time-sensitive requirements for promotions and events.

· Remote Management and Efficiency: No dedicated personnel are required to change posters on-site, significantly saving manpower and time, making

it particularly suitable for distributed locations.

· Enhanced Brand Technology Image: Digital display methods help project a modern, high-tech image.

· Interactivity and Data Collection (Advanced Features): Some advertising screens support touch interaction, facial recognition, and camera data

collection, enabling audience analysis and more targeted advertising.

III. Critical Considerations

Outdoor advertising screens are exposed to complex environments for extended periods, requiring careful consideration in their selection, installation,

and maintenance.

1. Hardware Selection and Protection

· High Brightness and Anti-Glare: Due to strong outdoor lighting, a high-brightness screen (typically ≥2000 nits) and anti-glare glass are essential to

ensure clear viewing even in direct sunlight.

· Wide-Temperature Operation: The device must withstand both extreme cold and extreme heat, typically operating within a temperature range

of -20°C to 55°C (-20°C) or even higher to ensure stable operation in all seasons.

· High Protection Rating:

· IP65 is the baseline rating: "6" represents complete dustproofness, and "5" represents protection against low-pressure water jets. This effectively

resists rain and dust.

· In areas prone to heavy rain and typhoons, even higher ratings may be required.

· Heat Dissipation and Heating:

· Heat Dissipation: An efficient internal heat dissipation system (such as air conditioning/fans) is required to prevent high temperatures from causing

device downtime or screen damage.

· Heating: In cold regions, a built-in constant-temperature heater may be required to prevent the LCD from malfunctioning at low temperatures. 

· Durability and Anti-theft: The housing should be made of sturdy metal (such as galvanized steel) and designed with a pry-resistant structure. 

It must be securely fastened during installation, and if necessary, equipped with an anti-theft lock and alarm.

2. Installation and Power Supply

· Location and Viewing Angle: Choose a location with high foot traffic and a wide field of view. Consider the audience's viewing angle and distance to

determine the appropriate installation height and tilt angle.

· Foundation and Load-bearing Capacity: Ensure that the mounting wall or column has sufficient load-bearing capacity. For vertical installation, a

solid concrete foundation is required.

· Power Supply: A stable and secure mains power connection is required. A voltage stabilizer and lightning protection device are recommended to

mitigate voltage fluctuations and thunderstorms.

· Network Connection: A wired network is preferred for stability and speed. If wiring is not possible, a 4G/5G router can be used, but data costs

and signal stability should be considered.

3. Content Management and Operations

· Content Strategy: Content should be concise and clear, with a clear focus. The duration of a single page of information should be minimal (typically

5-10 seconds). Use dynamic visual elements. Avoid text that is too small or too dense.

· Scheduling: Plan the playback of different content based on time periods and traffic patterns. For example, during breakfast hours, play advertisements

for nearby breakfast shops.

· Regular Maintenance:

· Software Maintenance: Regularly check for system updates to prevent virus intrusion.

· Hardware Maintenance: Regularly clean the screen and housing vents, and inspect wiring and structural stability.

· Compliance and Security:

· Content Review: Ensure that published content complies with the Advertising Law and related regulations and does not contain false or illegal information.

· Approval Procedures: Installing large-scale outdoor advertising equipment in public areas generally requires approval from government departments such

as the Urban Management Bureau and the Municipal Administration Bureau.

Summary: 

Outdoor advertising displays are a key component of digital city development. Their successful implementation relies on a comprehensive

approach: from initial hardware selection (high brightness, waterproofing, and a wide operating temperature range), to mid-term professional installation

(stable, secure, and compliant), to final, refined content operations and regular maintenance. Only by comprehensively considering these factors can

outdoor advertising displays operate stably and sustainably in harsh environments, ultimately achieving the desired commercial value and promotional impact.
