It has been argued that problems of selection bias and endogeneity can be addressed by stronger research designs such as randomized controlled trials and natural experiments. A 2017 review published in Journal of Scandinavian Studies in Criminology and Crime Prevention compiles seven studies that use such research designs. The studies included in the review found that CCTV reduced crime by 24 28% in public streets and urban subway stations. It also found that CCTV could decrease unruly behaviour in football stadiums and theft in supermarkets/mass merchant stores. However, there was no evidence of CCTV having desirable effects in parking facilities or suburban subway stations. Furthermore, the review indicates that CCTV is more effective in preventing property crimes than in violent crimes.

Like stand alone motion detectors, these can activate when you’re away from home or whenever you choose. For example, you may keep the window sensors always activated but deactivate the door sensors when you’re at home. These sensors can function as part of your security system or on their own, and they vary in size and design from tiny, sleek sensors to bulky and obvious. Sensors also vary in sensitivity. Some may trigger when the door or window vibrates versus actually opening. A carbon monoxide detector triggers when the level of carbon monoxide in your home reaches a dangerous level.
