Night vision lens

A cost-effective tachograph is essential for providing evidence of vehicle safety and insurance claims. Here are some ways to purchase a tachograph: Good video recording: Choose a dashcam with high resolution, at least 1080p full high definition resolution or better. High resolution dashcams can capture a lot of details, such as traffic signs, traffic lights, pedestrians, license plate numbers, etc. In the event of an accident or dispute, these records can be used as evidence to prove innocence and to support insurance claims. Wide viewing angle: The basic shooting angles are: 90 degrees, 100 degrees, 120 degrees, 140 degrees, 150 degrees, 170 degrees, etc. The more popular single-lens driving recorders are equipped with wide-angle lenses of 120 degrees or 140 degrees. When a single lens is 170 degrees, the picture will be seriously deformed, affecting the clarity of the picture. If you choose a driving recorder with a wide-angle lens, it is recommended that buyers use a viewing angle of at least 130 degrees to ensure a wider field of view is recorded. Night use: It is necessary to pay attention to the performance of the driving recorder at night or in low-light conditions. The driving recorder has a night vision lens that can capture the faint light that the human eye cannot detect and magnify it, allowing you to see objects and scenes in extremely dark environments. Storage capacity and loop recording: Driving recorders typically use a memory card to save recordings. Choose to have enough storage capacity to record as long as you need, while supporting loop recording to automatically overwrite old recordings when the memory card is full. G-sensor: The G-sensor can sense the force of a collision or sudden change, saving the relevant video footage as an emergency to prevent it from being overwritten by loops. Vehicle power and parking monitoring: Some tachographs have the ability to connect to the vehicle's power supply, which can automatically start recording in the event of an incident. In addition, some tachographs also have parking monitoring capabilities, which can record while the vehicle is parked.Car rearview lens can help car owners achieve the desired parking effect Convenience and versatility: Consider choosing a dashcam that is easy to use and set up. Other features include GPS recording, Wi-Fi connectivity, mobile app control, and more. Brand and user reviews: Select well-known brands and review the reviews and opinions of other users to understand the reliability, after-sales services and performance of the dashcam. Legal requirements: Understand the legal requirements and regulations in your area and ensure that the selected driving recorder complies with local regulations. 3C certification: At present, buses, buses and school buses need to install tachographs, logistics and transportation companies have also begun to install tachographs, and require products to be 3C certified. According to the tachographs regulations of the National Compulsory Certification Quality Center, tachographs and car black boxes must be 3C certified before they can be sold. Therefore, buyers should choose carefully when choosing products and buy products produced by regular manufacturers with 3C certification. Budget: Determine the scope of purchasing a tachograph according to your own budget, and make a trade-off between quality and functionality. Try to choose a well-concealed one to reduce the risk of window smashing and theft. Please note that these guidelines are for reference only, and buyers need to adjust them according to their individual needs and priorities, and carefully compare different brands and   models of dashcams before purchasing.

Surveillance camera lenses are classified according to the mode of operation: Fixed fixed focus camera lens:Used to monitor fixed scenes, such as entrances and exits or parking lot driveways. Rotary camera lens:The camera is placed on the rotating table and can be rotated left and right. Spherical camera lens:Can rotate 90 degrees vertically and 360 degrees horizontally. Usually placed in the four corners of the community building, the atrium landscape and the second foyer. Dome camera lens:Usually placed in elevators or more beautiful public facilities. Surveillance camera lens performance classification: General camera . Low-light camera. Infrared camera. Megapixel camera. Surveillance camera lens function classification: Infrared night vision surveillance camera 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. cyber security surveillance cameras 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 surveillance camera 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 camera lens 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.  CCTV camera lens 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.  smart home equipment surveillance camera lens 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: PTZ type (PTZ type integrated camera) 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. Gun type (gun type camera) 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. Ball model (ball camera) 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. Barrel model 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. hemispherical Generally integrated infrared lamp, audio and other functions, suitable for indoor, beautiful and compact appearance, recommended in shops, indoor and other environments.
