For important historical images such as the changes of the gate of Guangzhou Public Security Bureau from 1921 to 2017 and the information stronghold of Guangdong Province of the Communist Party of China in 1943, a flat cabinet with low-reflection glass and a constant temperature and humidity system is adopted. An adjustable angle display inclined plate is embedded in the display cabinet to facilitate the display of old photos, archives, and early certificates. 4000K neutral white light is selected as the lighting to highlight the details and age texture of paper exhibits.

The independent island cabinet design is adopted, and the cabinet body is equipped with dark gray metal frame and wooden base, with key lighting (Spotlight) and background story board inside. A touch screen can be integrated under the display cabinet to display the event background, character relationship map and historical map, enhancing the interactivity and narrative depth.

It is used to display souvenirs, badges, certificates and group photos in international police training, visits and exchanges. It is recommended to use hanging or wall mounted display cabinets, which are transparent and light, and support multi-layer display. The lighting adopts color adjustable temperature led (3000k-4500k is recommended to be adjustable), with bilingual exhibition logo, reflecting the image of open and professional police.

For the "Chinese People's Police Day in 2023" and historical ceremony related exhibits (such as flags, commemorative medallions, and props for the launching ceremony), a base type through cabinet is designed, and a movable wheel and a horizontal adjusting foot cup are reserved at the bottom of the cabinet to facilitate temporary exhibition arrangement or tour. RGB atmosphere light band can be added in the cabinet for dynamic lighting on festivals or special anniversaries.

All display cabinets adopt laminated explosion-proof glass+electronic lock+vibration alarm system, and are equipped with micro environment monitoring module (temperature and humidity, VOC, illumination). The cabinet structure supports independent power supply and remote monitoring to meet the high-level requirements of the public security system for the safety of cultural relics.
