What is a coaxial camera?

Question 1: What's the difference between a coaxial high-definition digital surveillance camera and a network surveillance camera? The coaxial camera in the field of vision is a network of millions of pixels, which is connected by analog wiring, that is, data cable, while the network camera is connected by network cable. The difference between them lies in the different wiring mode, and the coaxial camera is more suitable for engineering transformation.

Question 2: What is a coaxial camera? What do you mean? There are analog and high-definition video recorders. The analog is an ordinary video recorder, and the transmission line is coaxial cable (for example: SYV 75-5); And HD is transmitted through the network cable. I hope this helps.

Question 3: What is the difference between a 65438+300,000 pixel coaxial camera and a network camera?

This coaxial camera is an analog camera, and the 800 lines in the analog camera are also called 130W HD, but you are not sure about this concept at once, but I can tell you that literally, it is nonsense. The definition of analog cameras is still distinguished by lines, that is, analog signals. If the picture quality is not high, the 800-line S camera is very good.

However, the webcam 1.3 million is the real 1.3 million pixel, with high color reproduction and high output resolution, so I won't say much. On the other hand, the price of 1.3 megapixel webcam in the market is obviously higher than that of 1 megapixel, but the picture difference is not very big, so if you buy a webcam, 1 megapixel is the most suitable.

Professional answer, please adopt! ! !

Question 4: What about the coaxial HD camera 1? New technology breaks through the transmission distance limit of network cable 100 meters.

Coaxial high-definition network camera, beyond the transmission distance limit of traditional high-definition network, can use coaxial cable, telephone line, twisted pair, power cord and so on as transmission media, and the transmission distance can reach 2 kilometers. It is a brand-new high-definition network camera with long-distance transmission.

2. Compatible with mainstream NVR in the market.

The newly launched coaxial HD network camera does not need a dedicated back-end storage platform, supports the latest ONVIF protocol, and is compatible with NVR products of mainstream brands in the market, with stronger product compatibility and better flexibility.

3. Flexible network, plug and play.

Coaxial HD network camera supports star, bus and hybrid networking, which is convenient and flexible. Using multi-signal cable transmission technology, high-definition video signals above 16 can be transmitted on a coaxial line, which greatly reduces the line cost and improves the use value of the original line.

4. Simulate and upgrade HD in one step.

The coaxial million HD network cameras all adopt BNC output interface and follow the transmission interface of analog monitoring system. Customers only need to replace the camera and the back-end NVR to achieve a comprehensive upgrade of HD, reduce engineering construction and line costs, and bring customers a new experience of low-cost and convenient HD monitoring!

5. Special application

When it is applied to the elevator monitoring system, it effectively makes up for the situation that the network cable cannot be installed in the elevator. Some elevators can use the accompanying cable of the elevator for video transmission at the same time, with high reliability, no wiring and low cost. The application of the perimeter of the fence, using its serial port function, can complete the video transmission of multiple cameras such as the perimeter of the fence through one line.

Coaxial million HD network monitoring products, covering 6.5438+0 million pixel infrared waterproof gun, 6.5438+0.3 million pixel infrared waterproof gun, 2 million pixel infrared waterproof gun, low illumination million HD products, etc. Can meet the different needs of customers in various application environments. It is believed that the coaxial million HD network camera, as a new transmission mode of million HD network cameras, will further promote the market pace of HD analog upgrade and inject new vitality and power into the HD network monitoring market.

Question 5: What does the coaxial camera mean? There are generally two kinds of cameras, one is twisted pair (network cable) and the other is coaxial cable, like TV/cable TV cable. .

Question 6: What does Hikvision coaxial camera ctl mean? CTL and GND are switching control lines, which are the hardware of coaxial HD output and CVBS output.

Change the switch, the default is coaxial HD output, if the switching control line is short.

Road, the camera switches to CVBS output.

Question 7: What is a coaxial video recorder? What does coaxial mean? What's the difference with ordinary video recorders? There are analog and high definition video recorders. The analog is an ordinary video recorder, and the transmission line is coaxial cable (for example: SYV 75-5); And HD is transmitted through the network cable. I wish I could help you-

Question 8: What's the difference between coaxial surveillance cameras and analog surveillance cameras? 1, coaxial monitoring, you don't need to know the clarity but you need to know the wiring mode. It can be said that it is an upgraded version of ordinary analog monitoring, in order to let users of analog monitoring enjoy the effect of high definition through upgrading. Therefore, for users, it is necessary to understand that the definition of coaxial HD is much higher than that of analog, occupying more hard disk space, requiring higher wires and even higher power supply.

2. Connection mode: coaxial and analog are exactly the same, using video cable +BNC head; Of course, twisted pair transmission can also be used.

3. Line selection: Coaxial HD requires more video lines than ordinary analog monitoring.

4, if you want to access the coaxial camera, hard disk video recorder must use coaxial hard disk video recorder. Coaxial hard disk video recorder can be connected with coaxial camera or ordinary analog camera.

Question 9: What is coaxial monitoring? What's the difference between it and analog and network? 5-point coaxial HD uses the same coaxial cable as the analog camera to transmit high-quality video signals, which can achieve the image quality effect of 1080P. The network camera uses a network cable running on the network based on TCP/IP protocol.

Question 10: How much memory does the image head of the coaxial video recorder need? The resolution of coaxial HD camera is the same as IPC. Generally speaking, 720P and 960P cameras record about 2 1G 24 hours a day, and 1080P needs 42G.

Time depends on the rate setting.
