Surveillance Camera Lens Types and Recommendations
Oct 31, 2024Surveillance camera lenses are classified according to the mode of operation:
Surveillance camera lens performance classification:
Surveillance camera lens function classification:
The night vision function uses infrared sensing technology, the principle is that any object will emit heat, and objects of different temperatures emit different heat. The night vision function collects this information and converts it into a visual image, which can clearly present the surveillance scene at night, suitable for scenes that require monitoring at night.
The webcam is a front-end device that combines traditional cameras and network video technology. In addition to the latest webcam capabilities, it also has a digital compression controller and a web-based operating system built into the machine. After the video data is compressed and encrypted, it is sent to end users through the local area network or wireless network.
Explosion-proof cameras belong to explosion-proof monitoring products, because conventional camera products cannot be used in high-risk flammable and explosive sites. Cameras with explosion-proof functions and relevant certificates issued by national authorities are required to have explosion-proof functions. They are suitable for mines and high-risk scenarios.
ADAS cameras refer to cameras used in advanced driver assistance systems (ADAS). As a key visual sensor, they can capture image information and convert it into digital signals through in-depth processing, thus realizing ADAS functions such as forward collision warning, lane departure warning, and pedestrian detection.
The CCTV monitoring system is a cross-industry comprehensive security system that uses the world's most advanced sensing technology, surveillance camera technology, communication technology and computer technology to form a multi-functional and all-round monitoring highly intelligent processing system. The CCTV monitoring system can give people the most direct visual and auditory experience, as well as the visibility, real-time and objective record of the monitored object.
The application of lens technology in smart devices has greatly improved the functionality, image quality and overall performance of smart devices. Video conferencing cameras, bird feeder cameras, scanner robot cameras, cropper cameras, doorbell facial recognition cameras, parking lot cameras, scanner cameras, etc. all rely on lenses to capture clear, accurate and high-resolution images. As lens technology continues to advance, we can expect even more significant improvements in the performance of these smart devices, ultimately changing the way we perceive and interact with the world around us.
Surveillance camera lenses can be divided into:
Nowadays, only heavy-duty gimbal is available. Ordinary gimbal machines have been replaced by ball machines with built-in guns, telephoto lenses, and infrared or laser lamps. They are mainly used in remote monitoring systems such as forest fire monitoring, sea level, and water conservancy, with a high degree of professionalism.
The gun type is similar to the SLR camera body, which can be matched with the lens according to the needs, so the function is flexible, can be matched with different lenses, can be equipped with infrared lights, fill lights, radar capture and other functions, generally with IO expansion interface, mainly used in road monitoring and other high-demand scenes for cameras, but also the main components used in the PTZ interior, with a high degree of professionalism.
Dome cameras can generally rotate 360 degrees horizontally and 90 degrees vertically, and are suitable for all-round monitoring of a certain point. Generally, larger 6 or 7-inch ball machines are suitable for use in large scenarios, such as factories, agriculture, water conservancy and other engineering environments. 3, 4, 5-inch small ball machines, mini and compact, suitable for shopping and home use.
Integrated infrared light, good integration effect, used in ordinary outdoor monitoring, better waterproof, relatively cost-effective. Recommended for outdoor monitoring in factories, buildings, residences and other environments.
Generally integrated infrared lamp, audio and other functions, suitable for indoor, beautiful and compact appearance, recommended in shops, indoor and other environments.
Suitable for home use, integrated infrared lamp, audio and other functions, beautiful and compact appearance, recommended for home use, many participating companies, a wide range of options.
Surveillance camera lenses are divided according to imaging color:
Surveillance camera lenses are divided according to camera sensitivity:
When selecting a surveillance camera, you should consider the following factors:
