The surveillance camera is a kind of semiconductor imaging device, which has the advantages of high sensitivity, strong light resistance, small distortion, small size, long life, and anti-vibration. In the surveillance camera security system, image generation is currently mainly from a CCD camera, and the stored charge can also be taken out to change the voltage, which is widely used due to its anti-vibration and impact characteristics. Here we come to understand the types of surveillance cameras on the market today:
1. Night vision night vision <br> <br> actually use this technique is used in the infrared sensor, for example, automotive night vision system is mainly used is a thermal imaging technology, also known as infrared imaging. 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, clearly presenting objects that could not be seen at night, increasing the safety of night driving.
2. Waterproof position <br> <br> waterproof camera, it generally installed in the open air, for example, to install the car tail section, forming a rear view system, with a long somewhat vague situation will be mistaken for the water it affects the performance of the general camera There are several situations where there is a blur, a plastic lens 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 <br> <br> Network Camera is a traditional camera and network video technology combined with a new generation of products, in addition to a traditional camera image capture function outside all the latest webcam energy, the machine also has a built-in digital compression control The device and the WEB-based operating system make the video data compressed and encrypted and sent to the end user via a 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 <br> <br> digital camera refers to a stable and efficient energy carrier used in the field of video image capture device, it can be directly on the hard disk, such as integrated cameras currently online selling more fire image storage is directly The image is stored on the SD card. Compared with an ordinary camera, the digital camera has high comparability in resolution, frame rate, requirement for light, and exposure mode, among which the main component is a CCD sensor core.
The infrared camera infrared <br> <br> mainly achieved by ICR infrared filter, i.e. the filter is opened during the day to block infrared rays into the CCD, CCD so that only sensitive to visible light; night vision or light conditions In a bad state, the filter stops working and no longer blocks infrared rays from entering the CCD. Infrared rays enter the lens after being reflected by the object for imaging. The infrared camera has a low power supply and uses two types of infrared rays: near-infrared rays or short-wavelength infrared rays. From 0.76 to 1.5 microns, penetrating deep into human tissues, about 5 to 10 mm; far infrared or long-wave infrared, wavelengths from 1.5 to 400 microns, mostly absorbed by the superficial skin, penetrate tissue less than 2 mm deep. 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. <br> <br> explosion-proof camera monitoring products belonging to explosion-proof, explosion-proof product is a cross-industry with surveillance industry, since in high-risk flammable, explosive site can not use a conventional camera products, and there is need to have a national explosion-proof function The relevant certificate issued by an authoritative organization can be regarded as 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.
