In security monitoring projects, network cameras are now used in most scenarios. The IP camera is referred to as IPC, which is derived from its English name IP Camera. It is a combination of a traditional camera and a network coding module. At the same time, it compresses the analog signal into a digital signal and transmits it with a network cable, so that it can be directly used as a network device node. To use, it can be directly connected to a network switch or router.
The network cameras can be formed into a local area network, and then the video can be accessed from anywhere in the world with network access through network permissions, which is more convenient to view and manage.
For laymen, as long as they know the shape, structure and basic functions of the network camera, they can be used as an electronic device to have a general understanding. What do the letters and numbers of ?
Here we take the most commonly used Hikvision cameras as an example. Of course, the naming rules of different brands are different, but each official website or manual will have a detailed explanation.
These meanings come from Haikang's official website and are not guesswork. The most commonly used in the project is the network camera and the network ball machine, we will introduce the two named models respectively.
First of all, the first three, which are marked with ①DS-2 above, are the general name of front-end products and have no special meaning;
Mark ②CD: refers to the network camera;
Mark ③3: refers to the 3 series (and 1 is written here, which is the 1 series);
Mark ④1: LED infrared network hemisphere,
Other notes here:
2/A/T: Dot matrix infrared network barrel type
3: Dot matrix infrared network conch
4: Card type network camera
9: Fisheye camera
Q: PTZ IP Camera
Mark ⑤3: Here is 3 million pixels (2: 2 million pixels; 5: 5 million pixels)
Label ⑥5: H.265 encoding (0 or 2: H.264 encoding)
Mark ⑦FD: support SD card, not POE; (WD: support true wide dynamic)
Mark ⑧IWS: support infrared, support WiFi, support audio alarm.
Let's look at another network ball machine:
Mark ①DS-2: Front-end product model, no special meaning
Mark ②D: refers to the network ball machine
Mark ③C: economical ball machine
Mark ④7: 7 inch dome camera (5:5 inch dome camera)
Label ⑤1: 1.3 million (0: 1 million; 3: 3 million)
Mark ⑥20: 20x zoom (06: 6x zoom)
Mark ⑦I: support infrared (B: support white light)
Mark ⑧W: support H.265 encoding (Y: support H.264 encoding)
Label ⑨A: AC24V, outdoor, IP66
Other notes here:
D: DC12V, outdoor, IP66
D3: DC12V, indoor
DE3/W: DC12V/PoE, Indoor, Wi-Fi
We can basically judge the different functions of different product models from the product model, what kind of power supply mode the camera is, and what kind of encoding method is clear at a glance, I hope this article is useful to you!
