To determine whether the resolution of the LCD splicing screen meets surveillance requirements, the following aspects can be considered:
Detail Requirements of the Surveillance Subject
If clear identification of fine features, such as human faces or license plate numbers, is necessary, a higher resolution is required. For instance, in surveillance scenarios requiring the recognition of small text or complex patterns, a splicing screen with at least 1920×1080 Full HD or higher resolution should be selected.Surveillance Range and Viewing Distance
For larger surveillance areas viewed from a farther distance, the resolution requirements can be relatively lower. Conversely, for smaller surveillance areas viewed from a closer distance, a higher resolution is needed to ensure image clarity.Resolution of the Signal Source
It is important to understand the output resolution of the cameras or other signal sources used in the surveillance system. If the signal source itself has a low resolution, selecting a splicing screen with an excessively high resolution may not fully leverage its advantages.Practical Testing and Comparison
During the selection process, you can request Huabangying Technology to provide samples of splicing screens with different resolutions for practical testing. Compare the display performance under the same surveillance footage to evaluate how different resolutions perform.
