Currently on the market, there are many kinds of camera fields. Xiao Bian has a car camera and summarizes the seven features of the camera. The summary is as follows:
Includes seven features are: water proof IR remote network 1. Infrared <br> <br> digital infrared camera is mainly achieved by ICR infrared filter, i.e. the filter is opened during the day to block the infrared rays entering the CCD The CCD can only sense visible light. Under night or poor lighting conditions, the filter stops working. It 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 low power supply. There are two types of infrared rays: near-infrared rays or short-wavelength infrared rays, wavelengths of 0.76 to 1.5 microns, penetrating deep into human tissues, about 5 to 10 millimeters; far-infrared rays or long-wave infrared rays, wavelengths of 1.5 to 400 microns, mostly absorbed by the surface skin The penetration depth is 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.
2. The 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. Night Vision will be able to collect this information, and then converted into a visual image, originally put at night see objects clearly presented in front of added security 3. Waterproof <br> <br> waterproof camera driving at night, The general installation in the open position, such as the installation of the vehicle tail section, forming the rear view system, with a long time some vague conditions will be mistaken for the impact of the performance of the water, the general camera is blurred in several situations, a plastic lens height Under 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.
The degree of protection is based on the IP×× standard recommended by the International Electrotechnical Commission (IEC). Different installation locations have different levels. Specific selection can be made with reference to the following description. In the grading standard, “×׆is a two-digit number, with the first representing the level of protection against solids and the second representing the level of protection against liquids. There are 7 levels of solid protection grades, which are represented by 0-6, and liquid protection grades are 9 grades, which are represented by 0-8. Attach a waterproof and dustproof rating table below.
Dust protection level 0: No protection 1 : Prevent large solids intrusion 2 : Prevent medium solids from invading 3 : Prevent small solids from invading 4 : Prevent objects from entering solids > 1 mm 5 : Prevent harmful dust from accumulating 6 : Prevent dust completely enter
waterproof level
0: No protection 1: Water droplets drip into the housing No effect 2: When the housing is tilted to 15 degrees, water droplets drip into the housing No effect 3: Water or rain does not affect from the 60 degree corner to the housing 4: Liquid from any direction Spilled to the outer shell No harm effect 5: Flush with water without any damage 6: Can be used in cabin environment 7: Can withstand flooding for a short time (1m)
8: at long immersion under pressure <br> <br> 4. Explosion-proof cameras belonging to the explosion-proof monitoring products, is the product of cross-industry with explosion-proof surveillance industry, since in high-risk flammable, explosive site can not use a conventional camera Products that require explosion-proof functions and related certificates issued by national authoritative agencies can be regarded as explosion-proof cameras. 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 are anti-violence, anti-sabotage, or resistance to strike, etc., these products have a relatively hard shell, rather than have certified explosion-proof electrical properties and this is two very different nature of the product 5. Network <br> <br> The webcam is a new generation of products combining traditional video cameras and network video technology. In addition to the latest webcam capabilities for image capture in general traditional video cameras, it also includes a built-in digital compression controller and WEB-based operating system. The video data is compressed and encrypted and sent to the end user via 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 for network cameras also monitor, but the webcam in the traditional monitor above increased in conjunction with the Internet function 6. Remote <br> <br> in fact it is the use of a remote network, the use of 2G3G Or GPS signal, the previous paragraph through the video acquisition, conversion signal, and the remote user can use a standard web browser or professional development software on the PC, according to the IP address of the network camera, access to the network camera, real-time monitoring of the target site Conditions, and can edit and store image data in real time. At the same time, it can also control the camera's pan tilt and lens, and perform comprehensive monitoring.
7. Digital <br> <br> digital camera refers to a stable and efficient energy carrier used in the field of video image capture device, the image can be directly stored on the hard disk, like the current online selling more fire integrated camera, is the direct 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.
Combining these seven characteristics, I believe that the reader understands that these related characteristics of the camera have a general understanding. As long as the relevant areas of surveillance are covered, basically these contents are covered. Readers who are interested in monitoring classes can remember to purchase or customize them later. In order not to be misled by the hype of some salespeople.

Window Screen
A window screen (also known as insect screen, bug screen, fly screen, flywire, Wire Mesh, or window net) is designed to cover the opening of a window. It is usually a mesh made of metal, fiberglass, plastic wire, or other pieces of plastic and stretched in a frame of wood or metal. It serves to keep leaves, debris, bugs, birds, and other animals from entering a building or a screened structure such as a porch, without blocking fresh airflow.
