# Perception of Risks and Usefulness of Smart Video Surveillance Systems
## 5 Conclusions  
The presented study examined two research questions. The first research question investigated whether there are differences between genders, public areas or time of day with regard to the perceived usefulness of smart video surveillance using digital skeletons. The second one investigated whether there are differences between genders and different privacy levels in terms of perceived privacy risk. Examining the first research question showed the effects of gender, time of day and public areas. Furthermore, the interactions public area \(\times\) time of day and public area \(\times\) gender were also significant. Regarding the second research question, the effects of gender and privacy levels were shown. Previous research has only reported differences for the perceived acceptance or usefulness of video surveillance, regarding gender [45,46], times of day [5] or different areas [41]. The results of the presented study confirmed these effects; furthermore, they showed that the interactions public area \(\times\) time of day and public area \(\times\) gender were also significant in terms of perceived usefulness of smart video surveillance using digital skeletons. One interpretation for the first interaction could be seen in the common visiting hours of the analyzed areas. Perceived usefulness decreased at night in public areas which are not normally visited at night. A possible explanation of the second interaction could be that women perceived the investigated surveillance to be more useful in low-traffic places and men in high-traffic places. As mentioned earlier, this is the first time these interactions have been studied and found to be significant, so there is no previous literature to interpret them. Thus, further research is needed to provide more accurate conclusions about them. Overall, smart video surveillance of the digital skeletons can be seen as a promising solution for increasing security while reducing privacy risk. Based on the presented results, it is possible to provide targeted education on potential applications of surveillance. Furthermore, these results can help to better understand the factors influencing the acceptance of smart video surveillance.
