Monitoring at night is one of the most common uses for outdoor surveillance cameras, and in order to get a high-quality image, you’ll want to purchase a camera with infrared (IR) technology. Many models have a built-in IR cut-switch that automatically enables and disables the infrared technology depending on the lighting conditions. The number of infrared LEDs used in a camera will help determine how far of a night vision range a camera has.

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.

Home security cameras are DIY devices, meaning you set up and monitor them yourself, rather than hiring a security company to do the work and the watching. While they can save you from installation and monitoring fees, you forgo a 24/7 response team when you do it yourself. You’ll have to decide whether you’ll feel safer with professional monitoring or self-monitoring through alerts that pop up on your phone.

On 23 January 2011 the CCTV news program Xinwen Lianbo showcased the Chengdu J-10 in the air by firing a missile at an airplane, the target plane then exploded. This footage lasted half a second and the destroyed airplane shown was later identified as that of an F-5E, US fighter jet. It turns out the clip was taken from the 1986 US movie Top Gun.
