With the development of safe city construction, places are seeking to built a “social security dynamic networked digital surveillance system” to prevent crimes, and it can effectively protects the personal and property safety of urban residents. Safe city monitoring system will bring more security to people, and help realize the harmonious peace of the whole city and even the whole country.

An excellent tool for detecting potential intruders in total darkness is thermal imaging cameras. They need no light whatsoever to operate. Based on subtle differences in temperature, called heat signatures, thermal imaging cameras create a crisp image. A thermal imaging camera can also see through light fog and smoke.

Thermal imaging cameras are also extremely useful during daylight. Thermal contrast is extremely difficult to mask. Someone trying to hide in shadows or bushes and people that are trying to camouflage themselves, will become clearly visible on a thermal image. Thermal imaging cameras are also not blinded by the glare from the sun. They produce a crisp image in practically all weather conditions.
