- A basic question in practice is whether perceived image quality decreases when using a CCTV system (mediated) compared to direct observation (non-mediated). Three main characteristics were investigated: (1) test systems, (2) light conditions, and (3) image scaling. At (1) interpretable differences were found. At (2) normal light conditions (500 lux), no differences were found between mediated and non-mediated vision, while at 50 lux, mediated vision is significantly better. At (3) upscaling has a negative effect on quality of mediated observation. The results lead to clear indications for the setup of future research in laboratory as well as in practice.
