The earliest video surveillance systems involved constant monitoring because there was no way to record and store information. The development of reel-to-reel media enabled the recording of surveillance footage. These systems required magnetic tapes to be changed manually, which was a time-consuming, expensive and unreliable process, with the operator having to manually thread the tape from the tape reel through the recorder onto an empty take-up reel. Due to these shortcomings, video surveillance was not widespread. VCR technology became available in the 1970s, making it easier to record and erase information, and the use of video surveillance became more common.
The studies included in the meta-analysis used quasi-experimental evaluation designs that involve before-and-after measures of crime in experimental and control areas. However, several researchers have pointed to methodological problems associated with this research literature. First, researchers have argued that the British car park studies included in the meta-analysis cannot accurately control for the fact that CCTV was introduced simultaneously with a range of other security-related measures. Second, some have noted that, in many of the studies, there may be issues with selection bias since the introduction of CCTV was potentially endogenous to previous crime trends.In particular, the estimated effects may be biased if CCTV is introduced in response to crime trends.
Many sporting events in the United States use CCTV inside the venue for fans to see the action while they are away from their seats. The cameras send the feed to a central control center where a producer selects feeds to send to the television monitors that fans can view. CCTV monitors for viewing the event by attendees are often placed in lounges, hallways, and restrooms. In a trial with CCTV cameras, football club fans no longer needed to identify themselves manually, but could pass freely after being authorized by the facial recognition system.
Many homeowners choose to install CCTV systems either inside or outside their own homes, sometimes both. CCTV cameras are an effective deterrent to potential intruders as it increases the risk of identification through the camera footage. Most people will scout through affluent suburbs looking for the easiest house to break into. Having an obvious CCTV system, alarm or another security measure, makes the house appear to be a more difficult target so they will likely move on to the next house. Modern CCTV systems can be monitored through mobile phone apps which allows people to view live footage of their house from anywhere they have internet coverage. Some systems provide motion detection so when movement is detected, an alert can be sent to a phone.
