1. The night vision function is actually used This is the use of infrared sensing technology, such as car night vision system is mainly used thermal imaging technology, also known as infrared imaging technology. The principle is that any object will dissipate heat, and different temperature objects emit different heat. Humans, animals, and moving vehicles emit more heat than the surrounding environment. The night vision system can collect this information and then turn it into a visible image that clearly reveals objects that couldn't be seen at night in front of the eye, increasing the safety of night driving. 2. Waterproof and waterproof camera, generally installed in the open air The location, for example, the installation of a vehicle tail section, forms a rear view system, and when used for a long time, some vague conditions will be mistaken for affecting the performance of the water intake. Generally, there are several cases in which the camera is blurred, and a plastic lens is under high and low temperature aging conditions. The aging of the plastic lens became blurred. Second, there was water vapor in the camera and the glue was not good. Third, there was dust on the surface of the camera.
3. Network network camera is a new generation of traditional camera and network video technology combined, in addition to the traditional network camera with all the latest image capture capabilities of the network camera, the machine also has a built-in digital compression controller and WEB-based operation The system makes the video data compressed and encrypted and sent to the end user through LAN, internet or wireless network. People outside the general market are not easy to distinguish what is a monitor, what is a webcam. In fact, it can be said that the webcam is also a kind of monitor, but the webcam adds the function of combining with the Internet to the traditional monitor.
4.Digital digital camera refers to a video image acquisition device that can be stably and efficiently applied to the site of the carrier. It can directly store the image on the hard disk. The integrated camera that is currently sold on the Internet is to store the image directly on the SD card. Above, compared with ordinary cameras, digital cameras have high comparability in resolution, frame rate, requirements for light, and exposure modes, among which the main component is a CCD sensor core.
5. Infrared infrared camera mainly through the infrared filter to achieve day and night conversion, that is, open the filter during the day to block the infrared into the CCD, so that the CCD can only sense the visible light; night vision or poor lighting conditions, The filter stops working and no longer blocks infrared rays from entering the CCD. Infrared is reflected by the object and enters the lens for imaging. The infrared camera has low power supply and uses two kinds of infrared rays: near-infrared rays or short-wavelength infrared rays, with a wavelength of 0.76 to 1.5 microns. Into the human body is deep, about 5 to 10 mm; far infrared or long-wave infrared, wavelength 1.5 to 400 microns, mostly absorbed by the surface skin, penetrate tissue depth of less than 2 mm. Enhanced night image capture capabilities. The point to add here is that infrared light is invisible to the naked eye. You generally see the red light that appears above the camera. It is a photoresistor.
6. Explosion-proof and explosion-proof cameras belong to explosion-proof monitoring products, which is a cross product of the explosion-proof industry and the monitoring industry, because in the high-risk flammability, explosive site can not use the conventional camera products, need to have explosion-proof function and related certificates issued by the national authorities The product can be called an explosion-proof camera. A lot of readers can't distinguish between explosion protection and riot protection. Even more, riot protection products are used in high-risk areas where flammability is high. This practice has a very high risk factor, and even causes explosions that cause serious damage to people and property. Riot protection is anti-violence, vandalism, or impact resistance. This type of product has a relatively rigid outer shell and does not have the performance and certification of explosion-proof electrical appliances. These are two completely different products.
