Video surveillance is crucial to protecting people and property. However, daytime security cameras do not operate well in darkness when they are needed most. The additional lighting that would allow traditional cameras to work at night is expensive, generates light pollution and creates substantial maintenance constraints. Low-light cameras do exist, but they still require some ambient light to function. They often do not operate well during the day. Therefore, infrared imaging detection is a very attractive alternative. Since infrared imaging technology is a passive technology, it does not require an external light source. It can be used to observe and detect intrusions and other incidents in all-weather and lighting conditions. Security camera manufacturers can integrate infrared sensors into their products to provide new levels of performance and reliability:
