With the development of science & technology and the improvement of people's safety awareness, surveillance cameras have gradually attracted most people's attention and become more and more an indispensable part of people's lives. It applies to various places, such as force booths, shopping malls, school classrooms, community gates, and inside the house. As long as there is a need for security, there is surveillance camera. Surveillance camera this kind of semiconductor imaging device has the advantages of high sensitivity, anti-glare, small distortion, small size, long life, anti-vibration, easy operation, fast connection, etc. Its unique appearance greatly guarantees people's safety and privacy, and plays an important role in our daily lives.
There are many ways to classify surveillance cameras. According to different transmission signals, they can be divided into analog cameras and digital cameras. Classified by different screen resolutions, there are standard-definition cameras and high-definition cameras. Judged from different installation environments, there divides into indoor cameras and outdoor cameras. In terms of the different sensors, there exist CCD camera and COS camera. By different shape of the camera, it can be classified into spherical camera, dome camera and gun camera.
It always requires different functions for different applications, and it is the same to different design. For example, the spherical camera is generally mounted on the ceiling and used for hidden monitoring, the gun camera is mounted outdoors and support night vision. The dome camera can be rotated 360 degrees. Today, let’s talk about gun camera.
The gun camera is suitable for areas where there is insufficient light and the places that have no lighting equipment at night. It is particularly used in outdoor sites. Day and night shift function enables the camera automatically open its infrared radiation to detection objects and switch filter to clarify images at dark environments while there are no enough light being captured by camera. It can effectively reduce image noise and improve image quality in low illumination environment at night.
Also, the gun camera generally has other distinctive features. It is waterproof and dustproof as that it can be adapted to normal outdoor environment. Not only equipped with basic function of the ordinary camera, it is smarter and more user-friendly. It supports motion detection alarm. Once there is any movement, the camera’s PIR sensor will detect that and automatically send an alarm message to the mobile phone. No matter where you are, safety is always with you. According to different lenses, you can choose long-distance or wide-angle monitoring.
Our outdoor 3G surveillance camera JH012 is such a typical gun-type product. The long-range IR LEDs deliver clear night vision for continued protection—day and night. Motion detection alarm makes sure no movement will slip through without your notice. IP65 enables it works correctly even in tough conditions. Along with 720P resolution for great image clarity, it is also equipped with 105° wide angle all glass lens. In fact, it is difficult to suggest which cameras—spherical camera, dome camera or gun camera is better, the wiser way to choose different cameras are according to different requirements.
