Controlled Condensation in a Fixed Dome Camera Using Active Cooling
(2024) EITL05 20241Department of Electrical and Information Technology
- Abstract
- This thesis investigates the possibilities of preventing condensation from forming in the optical field of view in surveillance cameras with a dome through active cooling. The forming of condensation has been a challenge in these cameras, which can affect the quality of the image. By implementing different Peltier modules and varying their placement and power, this thesis has aimed to evaluate the ability of active cooling to prevent condensation from occurring in the optical field of view.
The methods include a combination of experimental tests, in both start-up cases and falling ambient temperature cases, and theoretical analysis to evaluate the effectiveness of different implementations. By comparing different sizes of Peltier modules...

The forming of condensation has been a challenge in these cameras, which can affect the quality of the image. By implementing different Peltier modules and varying their placement and power, this thesis has aimed to evaluate the ability of active cooling to prevent condensation from occurring in the optical field of view.
The methods include a combination of experimental tests, in both start-up cases and falling ambient temperature cases, and theoretical analysis to evaluate the effectiveness of different implementations. By comparing different sizes of Peltier modules and experimenting with different placements of them, the authors could assess their ability to decrease the amount of condensation formed and maintain optical clarity.
The results show that the use of active cooling is very effective in the falling ambient temperature case, and might be effective in the start-up case in domed surveillance cameras. Also, it shows that the active cooling should be placed far away from the optics for better results.
This study offers practical recommendations to improve the performance of surveillance cameras and also provides an understanding of the thermal and optical characteristics of such systems. Through the effective integration of active cooling, surveillance cameras with domes can, in some cases, perform high-quality surveillance in challenging environments. (Less)
