Elevator Digital Signage Installation Step-by-Step: A Manufacturer's Complete Guide

After years in the elevator advertising screen industry, we've identified a common issue: many projects only reveal installation problems during the acceptance phase—improper wiring, insufficient load-bearing capacity, unstable network signals, and even the need for rework or complete reinstallations. The core reason behind this lies in the lack of systematic construction processes and standards among installation teams.

In this article, we systematically organize the installation experience accumulated over years by our factory in serving hundreds of elevator media projects. From preliminary surveys to final acceptance, the process is broken down into seven modules step by step. Whether you are a property manager, installation engineer, or system integrator, this guide will help you solidify the installation process.

If you are selecting models for your project, you can first browse our certified elevator advertising display solutions to learn about the full range of models, then make matching decisions based on the installation key points in this article.

 1. Pre-installation Preparation

The installation quality of elevator advertising screens is 80% dependent on whether the preliminary preparations are thorough. According to our project statistics, over 60% of installation rework issues can be traced back to oversights during the survey phase. A comprehensive pre-installation checklist can help you avoid the vast majority of on-site problems

 On site survey: key parameters of elevator car

Before installation, a comprehensive survey of the elevator car must be conducted, with core parameters including：

• The dimensions of the inner wall of the elevator car (width, height, depth), confirm the available space in the screen installation area
• The material of the car wall (stainless steel, aluminum plate, wooden decorative surface, glass, etc.) determines the fixing method
• The top space of the elevator car and the location of the inspection port affect the routing path
• Layout of existing equipment in the elevator car (control box, handrails, ventilation openings) to avoid conflicts
• Evaluate the impact of elevator operating speed and vibration amplitude on the installation structure

 Power supply and network environment inspection

Power supply and network are the two basic conditions for the operation of elevator screens, which must be confirmed before installation：

• Confirm that there is an available power interface in the elevator machine room or roof, with stable voltage (AC 220V ± 10% or DC 24V)
• Assess the capacity of the power supply line to ensure that the newly added screens will not be overloaded
• Confirm whether an independent circuit power supply is required (according to fire safety regulations)
• Test the wireless signal strength inside the elevator car and determine the network access plan
• Check the number of available cores in the elevator's accompanying cables and evaluate whether they can be reused for routing

We provide a standardized 'Installation Environment Checklist' before the start of each project to help customers confirm site conditions item by item and avoid rework due to omissions.

 Size confirmation and product selection

Select the appropriate screen size and model based on survey data：

• Single screen solution: suitable for standard elevator cars with walls of 1-2 square meters
• Dual screen solution: suitable for advertising coverage needs on opposite or adjacent walls
• Confirm the matching relationship between the screen appearance size and installation area, and reserve heat dissipation space
• Confirm the compatibility between the installation method (wall mounted/embedded/bracket) and the material of the car wall

 2、 Choose the appropriate installation method

The installation method of elevator advertising screens directly affects the difficulty of construction, visual effects, and ease of maintenance in the later stage. Different car structures and project requirements require different installation plans. We have accumulated experience in three mainstream installation methods in actual projects. Below are the applicable scenarios and precautions for each method.

 wall-mounted installation

Wall mounted is the most common installation method, suitable for the vast majority of standard elevator cars：

• Secure the screen to the car wall using expansion bolts or specialized hangers
• Suitable for stainless steel walls and aluminum plate walls, requiring the use of specialized drill bits
• The installation height is generally 1.4-1.6 meters from the center of the screen to the ground, which is in line with the passenger's head up perspective
• Advantages: easy construction, convenient maintenance, and minimal modifications to the elevator car
• Attention: It is necessary to confirm the load-bearing capacity of the wall surface. It is recommended to add a back plate to disperse the stress on the stainless steel wall surface

 Embedded installation

Embedded installation aligns the screen with the car wall for the neatest visual effect：

• It is necessary to make holes on the wall of the elevator car to embed the screen for installation
• Suitable for new elevator supporting projects, installation positions can be reserved during the car manufacturing phase
• Significant modifications have been made to the car structure, and the renovation project requires an evaluation of the wall structure strength
• Advantages: High aesthetic appeal, no occupation of car space, good resistance to damage
• Attention: It is necessary to ensure that the opening does not affect the structural strength and fire performance of the elevator car

 Bracket installation

Bracket installation fixes the screen cantilever on the car wall or top through a dedicated bracket:

• Suitable for scenarios where the wall cannot be directly fixed (such as glass walls, decorative panels)
• Support structures can be installed at the top crossbeam or wall corners of the elevator car
• Suitable for special installation positions that require adjusting the screen angle
• Advantages: High flexibility, no direct damage to the wall, strong adaptability
• Attention: The bracket must undergo load-bearing calculation, with a safety factor of ≥ 3 times

 3、 Wiring scheme (power supply + network)

Wiring is the most challenging aspect of elevator screen installation that tests professional expertise. Elevators are sports equipment, and cables must move up and down with the car, while also withstanding long-term bending, vibration, and temperature changes. We have dealt with many signal interruptions, power failures, and even cable breakage accidents caused by improper wiring. Below are some practical experiences of mainstream wiring solutions.

 Accompanying cable solution (power supply + wired network)

The accompanying cable is the standard cable channel connecting the elevator car and the machine room, and is the most reliable wiring path：

• Utilize redundant cores in elevator cables to transmit power and signals
• Suitable for new elevator projects, reserve sufficient redundant cores in advance
• The power supply uses shielded cables, which are routed separately from the signal lines to avoid electromagnetic interference
• Wired network transmission is stable and reliable, suitable for content push scenarios that require high bandwidth
• If there are no redundant cores in the accompanying cables during the renovation project, a new plan needs to be developed

 Top WiFi Relay Solution

Install WiFi hotspot at the top of the elevator shaft or in the machine room, and connect them to the elevator car through WiFi module：

• No additional wiring required, suitable for renovation projects
• AP (wireless access point) needs to be deployed inside the well to ensure signal coverage
• WiFi signals may experience severe attenuation in metal cars, and antenna positions need to be designed reasonably
• Suitable for scenarios with low bandwidth requirements (static image slideshow, short videos)
• Recommend using the 5GHz frequency band to reduce interference with other devices

 4G/5G module solution

Integrate 4G/5G communication module on the screen and achieve remote management through mobile network：

• Completely independent of the elevator wiring system, the installation is the easiest
• Suitable for renovation projects without network cabling
• Stable mobile signal coverage is required, and signal strength must be measured before installation
• The SIM card needs to be selected as an IoT specific card to ensure long-term stable connection
• Suitable for distributed deployment and single point content update operation scenarios

 4、 Structural installation steps (step-by-step practical operation)

This is the core chapter of the entire article. We present the complete standard construction process summarized by our factory's installation team. Following this process can effectively avoid common installation errors and ensure that the first acceptance is passed.

 Step 1：Accurate measurement and marking

• Use a laser level to determine the installation centerline and horizontal reference line of the screen
• Mark the installation hole positions, with a hole spacing deviation not exceeding ± 1mm
• Confirm the distance between the installation location and other equipment inside the elevator car (≥ 50mm)
• Mark the routing path and avoid moving parts of the elevator car

 Step 2：Drilling and fixing

• Select the appropriate drill bit based on the wall material (HSS drill bit for stainless steel, woodworking drill bit for aluminum plate)
• The drilling depth is determined according to the specifications of the expansion bolt, generally 40-60mm
• Remove metal debris from the hole to prevent the risk of short circuit
• Install expansion bolts or chemical anchor bolts to ensure secure fixation
• Install the hanger/bracket and tighten it to the specified torque with a torque wrench

 Step 3：Wiring

• Connect the power cord (pay attention to the positive and negative poles), network cable/communication cable according to the wiring diagram
• All joints are treated with waterproof insulation, and the spacing between cable fixing ties is ≤ 200mm
• The wiring inside the accompanying cable needs to be completed in the car roof junction box using terminal blocks
• After the wiring is completed, conduct a power on test to confirm that the voltage is normal

 Step 4：Hanging and leveling

• Two people cooperate to hang the screen onto the hanger/bracket, paying attention to collision protection
• Use a spirit level to calibrate the screen levelness, with a deviation of ≤ 1mm/m
• Tighten the fixing screws and confirm that the screen is not shaking
• Check the uniformity of the distance between the screen and the wall surface

 Step 5：Debug

• Turn on the power and check if the screen display is normal
• Test touch function (if applicable), calibrate touch coordinates
• Connect to the CMS system and confirm that the remote management function is functioning properly
• Play test content, check audio and visual synchronization and color performance

Before leaving the factory, the elevator screens of Clientop undergo complete machine debugging. After installation on site by the customer, they can be powered on and used immediately, greatly reducing on-site construction time. Our elevator advertising screen system all support a plug and play rapid deployment mode.

 5、 System configuration and networking

After the hardware installation is completed, the system configuration determines whether the device can truly be put into operation. We have found that common issues in the system configuration process during customer service are mostly related to network settings and CMS binding. Standardizing this step will make subsequent operations much easier.

 CMS system binding

• Add a new device in the CMS management backend, enter the device SN code to complete the binding
• Set basic information such as device name, installation location, and project affiliation
• Configure device grouping for batch management
• Confirm the online status of the device and verify that the communication link is normal

 Split screen and playback strategy setting

• Configure split screen areas based on the physical layout of the screen (such as full screen, top and bottom split screen, picture in picture)
• Set up playlists and scheduling strategies (rotating by time slot and scene)
• Configure emergency broadcast function to receive fire/emergency information
• Set automatic on/off time to synchronize with elevator operation time

 Remote management and content push

• Configure content automatic download and caching strategies to reduce dependence on real-time network
• Set up device status monitoring, including parameters such as temperature, brightness, network signal, etc
• Enable AI remote diagnosis function, the system automatically detects abnormalities and pushes alert

 FAQ

Q1: How long does a typical elevator digital signage installation take?

A standard single-screen installation typically takes 2-4 hours, including mounting, wiring, and basic configuration. Dual-screen setups or embedded installations may require 4-8 hours. Complex projects with extensive wiring through the elevator traveling cable can take a full day. Proper pre-installation survey and preparation significantly reduce on-site time.

Q2: What is the most reliable network solution for elevator displays?

For new elevator installations, using the traveling cable for wired Ethernet provides the most stable and reliable connection. For retrofits where cable access is limited, a 4G/5G IoT module offers excellent independence from elevator infrastructure. WiFi relay works well for basic content delivery but may struggle in metal-shielded elevator cabins with weak signal penetration.

Q3: Can elevator screens interfere with the elevator control system?

Properly designed and certified elevator displays should not interfere with elevator controls. This is achieved through EMC compliance, proper isolation between display power and elevator circuits, and shielded cabling. Screens must meet EN 55032/55035 or FCC Part 15 standards. Always choose certified products specifically designed for elevator environments.

Q4: What safety checks are mandatory after elevator screen installation?

Key safety checks include load-bearing verification at 1.5x screen weight, insulation resistance testing above 1MΩ, grounding resistance below 0.1Ω, emergency power-off functionality, and fire alarm interface verification. Additionally, EMC field testing confirms the screen does not affect elevator operations. All checks should be documented for regulatory compliance.

Q5: How do you maintain elevator digital signage in a moving cabin?

Regular maintenance includes monthly visual inspection of mounting hardware tightness, quarterly cleaning of display surfaces and ventilation ports, and semi-annual cable inspection for wear from movement. Remote monitoring via CMS can detect issues proactively. Choose products with vibration-rated components and robust enclosures designed for the elevator environment to minimize maintenance frequency.
