The role of surveillance cameras in security is primarily to monitor and record activities, serving two crucial functions: documentation and deterrence. When placed in various locations, these cameras capture real-time footage of events, which can be vital for investigations and providing evidence in case of incidents such as theft, vandalism, or other unlawful activities. This recorded data is essential for law enforcement and can help in identifying perpetrators and understanding the sequence of events that took place.

Moreover, the presence of surveillance cameras often acts as a deterrent to potential criminal behavior. Knowing they are being monitored can discourage individuals from committing offenses for fear of being caught on camera. This dual purpose reinforces the effectiveness of surveillance systems in enhancing overall security in both public and private spaces.

The other options do not accurately reflect the primary purpose of surveillance cameras. Although they can complement security personnel's work, they do not eliminate the need for human oversight entirely, as human judgment and response are critical in many situations. Surveillance systems do not serve as entertainment, nor can they replace physical security measures—rather, they are tools that enhance existing security protocols.
