The installation of one-way see-through glass should follow the following five steps:
1. One-way see-through glass is divided into positive and negative sides. The front side is a glass mirror (mercury surface), which is used to reflect light. The front side should be oriented toward the monitored room (ie, the space to be observed, such as the space where the suspect is located); the reverse side is facing the position of the judge (ie: Monitoring room, such as the police space).
2. The intensity of the light in the monitored room should be sufficient to ensure sufficient brightness. The brighter and stronger the light in the monitored room, the more obvious the one-way perspective effect of the glass.
3. In order to achieve a better one-way perspective performance of the glass, the ceiling of the ceiling is not installed in the monitoring room, and no other light source is allowed. If there is a window next to the monitoring room, it must be installed with opaque curtains, such as sealed curtains used in hotels. When using, it is recommended to turn off all lights in the monitoring room.
4. If the monitoring room must use the light, it is recommended to use point lights, such as writing table lamps (the lamp cover is opaque), to narrow the scope of the light, and to control the light ratio of the monitoring room to the monitored room at 1:10. In the state, or a lower ratio, to ensure that the one-way perspective performance of the glass is intact. (Note: The light cannot be mounted directly behind the glass to prevent the image of the monitoring room from being reflected on the glass surface.)
5. In order to enhance the overall reflectivity of the unidirectional glass, it is recommended to install a spotlight above or below the glass mirror to enhance the overall reflectivity of the glass mirror and enhance the one-way visual effect of the glass.
6. The actual distance between the monitored personnel and the one-way see-through glass should be kept above ≥0.8--1 meters.
7. One-way glass is special glass. When installing, pay attention to protect the glass mirror. Once the mirror is damaged, it cannot be repaired. Suggestions:
In order to enhance the overall specular reflectivity of the unidirectional see-through glass, it is recommended to uniformly mount three to four 150W-200W spotlights (white, ie, colorless) above the glass mirror, and angle the 45-degree angle to the middle of the glass mirror to reinforce the glass mirror. The overall reflectivity enhances the one-way perspective of the glass. (If the light in the monitored room is bright enough, this advice can be ignored.
