​​How to choose a reliable supplier? Three key points of field investigation​ ​
When choosing an outdoor monitoring screen supplier, it is recommended to give priority to manufacturers with automated production capabilities. Manufacturing bases with monthly production capacity exceeding 10,000 square meters can often ensure supply stability, and focus on checking whether the workshop is equipped with quality inspection equipment such as full spectrum detectors. There is an industry experience: the product defect rate of factories that have passed ISO9001 certification is usually controlled below 0.3%.

​​List of qualification documents that must be verified​​

• International certification: CE certificate (electromagnetic compatibility instruction number must be within the validity period)
• Protection level: IP65 actual test report (focus on salt spray test data)
• Energy Efficiency Document: Energy Efficiency Labels Comply with EU ERP Directives

​​Technical Parameters Pit Avoidance Guide: These values ​​determine service life​​
The brightness adjustment range is the core indicator. It is recommended to choose an adjustable product of 4000-7500cd/m² in outdoor environments. There is a test data:​ ​Brightness intelligent adjustment technology​ ​The monitoring screen can reduce the average annual electricity bill by 42%. The refresh rate must be ≥1920Hz, otherwise the monitoring screen will experience shadow distortion at night.

​​Comparing the three advantages of traditional monitoring solutions​​

​​The golden rule of installation and deployment: Prevent problems before they happen​​

1. ​​Foundation burial depth​ ​: Calculated as 1/10 of the screen height (for example, 6 meters high requires digging 0.6 meters deep)
2. ​​Power distribution redundancy design​ ​: 20% buffer space is reserved for total power
3. ​​Thermal system layout​ ​: ≥2 temperature-controlled fans per square meter

Special reminder: 87% of screen failures are due to improper power configuration. It is recommended to adopt a split-channel power supply design, with an independent 600W power module configured for every 3 square meters, and lightning protection device is installed.

​​Four terms that must be clearly defined for after-sales service​​

• Free replacement of faulty modules during the warranty period (response time required)
• Provide remote diagnostic system access permissions
• Including professional dust removal and maintenance twice a year
• Written commitment to store spare parts library

A smart city project data display, select​ ​24-hour technical response​ ​For the users who serve, the equipment utilization rate has been increased by 35%, and the time for sudden failure handling is shortened to within 4 hours. Priority is recommended for suppliers that provide full-life cycle technical support, which is crucial for monitoring systems that require 7×24 hours of operation.

From an industry observation, suppliers who truly have engineering implementation capabilities will provide the "Ambient Light Analysis Report" and "Electromagnetic Interference Prevention Assessment" at the program design stage. These details often determine the stable performance of the monitoring system in five years, and are more valuable than simply comparing the price.
