Hi, all!
Good day to you!
Many users do not know whether to choose an analog camera or a network camera when installing a surveillance system.
If you consider the price alone, the price of an analog camera is a big advantage. But what about development needs and applications? Indeed, network monitoring has been a controversial topic in the surveillance market. So most users can't decide which camera to use.
This article will take you through the differences between analog cameras and webcams.
What is Analog/Network Monitoring?
Analog monitoring: Traditional analog monitoring uses BNC connectors and transmits data over coaxial cables. Generally, the transmission distance is less than 300 m. During use, the failure rate is high. Analog monitoring is used only in a small area (within 300 meters) and costs less than network monitoring.
Network monitoring: Data is transmitted over the network. Generally, network cables (within 100 meters), optical fibers, and wireless bridges are used. The performance is stable, and faults are not likely to occur in the future. PoE can be used to install the network monitoring system. Only one network cable is used to route the network monitoring system, which is easy to manage.
Differences between analog monitoring and network monitoring
Sharpness
Currently, network cameras can output images of millions or even tens of millions of pixels, while analog cameras can only output images of CIF and D1.
Management Differences
The IPC has a built-in web interface, which allows you to remotely manage and view images. The network camera also allows you to store image data on a remote hard drive. Analog cameras are a locked-down system compared to network cameras and cannot be monitored remotely. Videos can only be stored locally and cannot be viewed remotely.
Integration
The IPC has a built-in operating system, which can be integrated with the continuous presence management software to implement multi-channel surveillance. The number of channels is not limited and the hardware cost is not increased. The analog camera needs to be connected to the DVR, and the number of DVR channels is limited. If the number of cameras exceeds the channel number of DVRs, DVRs need to be added, increasing hardware costs.
Remote monitoring
IPCs can be remotely managed, such as recording settings, PTZ control, alarm settings, and two-way intercom. Analog cameras can only be managed by viewing images locally.
Costing
Cables used for network cameras typically cost 30 to 40 percent less than coaxial cables of the same quality. One network cable can support hundreds of network cameras and other devices at the same time. Each analog camera requires a cable to connect. If you have multiple cameras, you have to purchase cables that match the cameras, therefore, the hardware maintenance costs are high.
Camera installation
The webcam simply connects it to the nearest network and assigns an IP address. It can use the existing network as a transmission platform without cabling. Analog cameras need to connect coaxial cables to each camera, control platforms, video recording devices, and display devices.
Each additional route has to be rewired, and there is no ready-made network to take advantage of.
