LED display screens are different from general electronic consumer products. It involves the whole process from pre-sale consultation, scheme design to after-sale construction, installation and maintenance. In order to smoothly implement the LED display screen project, you need to pay special attention to the pre-sale on-site survey.

Many customers may not know whether the installation environment meets the requirements when purchasing LED display screens. LED Display screen experts need to obtain first-hand data through on-site surveys in order to formulate reasonable installation plans, including:

• Confirming power supply and communication plans
• Avoiding potential construction obstacles
• Evaluating the feasibility of the overall project.

So, what needs to be done during the pre-sale on-site survey of LED screens? SightLED will introduce the precautions for pre-sale on-site survey.

Understand the specific needs of users

Before conducting on-site surveys, you first need to communicate with users to fully understand their needs. This step is very critical and directly affects the subsequent scheme design and equipment selection. You need to mainly understand the following aspects:

Types and sizes of LED display screens

• Do users want to install indoor or outdoor screens?
• Do you need a full-color LED display or a monochrome/dual-color screen?
• What is the specific display size?

Installation environment

• Is the LED display installed on the wall, on the ground, or suspended?
• What is the surrounding environment of the installation site?
• Are there any obstructions or other influencing factors?

Display content and method

• What is the main display content? Is it video playback, picture display, data report, or text information?
• Is remote control required? Is real-time data update required?

Communication method

• What signal transmission method is used? LAN, WiFi, 4G/5G wireless communication, or optical fiber?
• What is the required communication line length?

The collection of these basic information will help engineers conduct more targeted inspections and data recording during on-site surveys.

Specific content of on-site surveys

Display installation location and installation method

LED displays have a variety of installation methods, including inlay, floor-standing, hanging, wall-mounted, supported, pillar-type, etc. Therefore, when you conduct on-site surveys, you must focus on the following points:

Wall conditions:

If it is a wall installation, you need to confirm the load-bearing capacity of the wall and whether it is suitable for installing brackets or directly fixing the screen. If there are decorative panels or other coverings on the wall, you must communicate with the user to confirm the removal or adjustment plan.

Geological conditions:

If it is a column installation, you need to understand the foundation conditions. Especially for outdoor LED displays, if the foundation is unstable (such as there is a mud layer underground), it may cause the columns and screens to sink or even collapse.

Obstacle inspection:

Confirm whether there are obstacles at the installation site that affect the visibility or construction operation of the LED display. If it is a mosaic installation, check whether the size of the reserved installation slot is appropriate.

 Power supply conditions

• LED display screens are high-energy-consuming equipment, and you also need to pay attention to power supply issues. The following needs to be confirmed on site:
• Power supply equipment: Is the capacity of the machine room or transformer sufficient to support the operation of the display? Is it necessary to increase the capacity?
• Line layout: Do existing lines need to be re-laid? Does it meet national electrical standards?

Voltage specification:

• Is three-phase electricity (380V) or single-phase electricity (220V) used?
• Is there an independent ground wire? Is the three-phase five-wire system complete?
• If rewiring is required, the specific length of the power line needs to be measured so that planning can be done in subsequent construction.

 Control location and communication line

• The remote control and data transmission of the LED display require a stable communication line. The following should be confirmed during the on-site survey:
• The control end location of the display: Is it convenient for maintenance and operation?
• The smoothness of the communication line: Is it necessary to lay additional network cables or optical fibers?

Signal transmission distance:

• The transmission distance of ordinary network cables (category 5e network cables) should be less than 120 meters, otherwise a signal amplifier needs to be added or optical fibers need to be used instead.
• Multimode optical fiber is recommended within 500 meters, and single-mode optical fiber must be used for more than 500 meters.

External environment inspection

For outdoor LED displays, you need to pay extra attention to the following environmental factors:

• Waterproof and moisture-proof: Does the display need to be waterproofed? Is the protection level sufficient?
• Lightning protection measures: Is it necessary to install a lightning rod? Are there any high-rise buildings or lightning protection devices nearby?
• Temperature influence: What are the highest and lowest temperatures in the local area? Is it necessary to install air conditioners or fans for heat dissipation?
• Air quality: Is it close to the sea or chemical plant? If the air contains a high amount of salt and alkali, special anti-corrosion materials need to be selected.

Preparation of construction equipment and tools

During the site survey, You can prepare the following tools:

• Measuring tools: tape measure, laser rangefinder, etc.
• Camera equipment: take pictures to record site details for subsequent solution design
• Construction equipment: Is scaffolding or other auxiliary equipment required? Does the customer need to provide a computer for system testing?

Additional special considerations for outdoor LED display screens

In addition to basic site surveys, the outdoor LED display screens installation needs to pay attention to the following points:

Influence of bad weather

• LED display screens are exposed to the outdoors for a long time and are easily eroded by rain, so waterproof and dustproof measures need to be taken.
• If installed at high altitude, wind resistance needs to be considered to ensure that the installation structure is firm.

Lightning protection

• We recommend installing lightning protection devices near the LED display and control system to prevent lightning damage to the equipment.
• All lines (signal lines, power lines) should be grounded for lightning protection.

Heat dissipation

LED display screens generate a lot of heat when running, especially in high temperature environments. Therefore, you need to add cooling fans or air conditioning equipment to prevent malfunctions caused by excessive temperature.

Summary

LED display screens Pre-sales site survey is a complex and important task. You need to consider multiple aspects such as installation environment, power supply, communication, construction conditions, and special environmental factors. Only through comprehensive and detailed surveys can you ensure the smooth installation process and ensure the stability and safety of subsequent use.

If you cannot conduct on-site surveys, you can also obtain necessary data through video calls, photos, or user-cooperated measurements to develop a reasonable installation plan. In short, doing a good job of pre-sales site surveys can not only improve the installation quality of LED display screens, but also enhance customer satisfaction.
