Q124 (CISF/2023) Science & Technology › ICT, AI, Cybersecurity & Emerging Tech

With regard to CCTV monitor, which one of the following statements is not correct ?

Monitor should be placed in a curved configuration

The monitor screen should be tilted upward to avoid reflection of overhead lighting

If possible, stacking of monitors should be avoided

Screens should be placed in a sequence, providing logical continuity with relation to location of cameras

In the design and ergonomics of CCTV control rooms, the following principles are generally applied to ensure operator efficiency and reduce fatigue:

Option B is incorrect: To minimize glare and reflections from overhead ceiling lights, monitor screens should typically be tilted downward or positioned vertically. Tilting a screen upward would cause it to reflect overhead luminaires directly into the operator's eyes, obscuring the image.
Option A: Placing monitors in a curved configuration (an arc) ensures a consistent viewing distance and angle for the operator, reducing eye strain.
Option C: Stacking monitors vertically should be avoided where possible because it causes neck strain and makes it difficult for operators to monitor all screens effectively.
Option D: Screens should follow a logical sequence (e.g., following the physical path of a building) to help the operator maintain spatial awareness when tracking subjects across different cameras.
