Analog cameras and network cameras are now mainstream products. How much do we know about our products while we use them? Do we know the difference between the two? Here's to explain what is the difference between the two cameras:
Analog Camera:
An analog camera (Camera) is a front-end device for acquiring and monitoring a live image. It uses a CCD image sensor as a core component, plus a synchronization signal generation circuit, a video signal processing circuit, and a power supply. In recent years, new low-cost CMOS image sensors have developed rapidly. Cameras based on CMOS image sensors have begun to be applied to videophones or conference television systems that do not require high image quality. Since the resolution and low illumination of the CMOS image sensor are temporarily inferior to those of the CCD image sensor, the use of the camera in the television monitoring system is still a CCD camera. The signal output from the analog camera is a video signal and can only transmit one-way video signals. It needs to be connected to a monitor or hard disk recorder for monitoring and recording.
IP Camera:
IP Camera integrates the video compression and network transmission processing module (DVS) on the basis of the analog camera and combines the technical features of analog cameras and video servers. Network cameras can be operated independently as long as they are located in any location with an IP network interface. In addition to all the image capturing functions of traditional cameras, the network camera also has a built-in digital compression controller and WEB-based operating system (including Web server, FTP server, etc.), making the video data compressed and encrypted, through the network ( Local network, Internet or wireless network) is sent to the end user, and the remote user can use a standard web browser or client software to access the network camera on their PC, real-time monitoring the situation of the target site, and the image data Real-time storage, in addition to the network can be controlled by the camera's head and lens, all-round monitoring. Some network cameras also have other functions such as voice intercom, alarm input, relay output, motion detection, analog video output, and SD card local storage of video data.
to sum up:
The network camera (digital camera) simply means that the camera itself will directly convert the captured image into a digital signal through the CCD and the internal circuit, which can be transmitted directly through the network cable and the switch. An analog camera simply converts the image to an analog signal and transmits it over a coaxial cable. Due to advanced technology, network cameras will gradually replace analog cameras and become the mainstream of surveillance.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
