Network Camera VS traditional analog camera

A simulated camera and a Network Camera seem to be a pair of friends in monitoring, often because you don't have me, I don't have you. Because of this, many users do not know whether to choose a simulated camera or a Network Camera when installing the monitoring system. In the monitoring market, network monitoring has always been a controversial topic. In terms of development requirements, the advantage of network monitoring is to simulate

A simulated camera and a Network Camera seem to be a pair of friends in monitoring, often because you don't have me, I don't have you. Because of this, many users do not know whether to choose a simulated camera or a Network Camera when installing the monitoring system.

In the monitoring market, network monitoring has always been a controversial topic. In terms of development requirements, the advantages of network monitoring are incomparable to that of analog monitoring. However, the slow release of simulated monitoring has also aroused more reflections. for users, the price of simulated cameras is low, the price of network cameras is expensive, and the two sides are weighed, many users have decided on the price advantage, which is often the breakthrough space of a simulated camera.

What is the difference between a simulated camera and a Network Camera? I believe that everyone can come up with a general definition, that is, the Network Camera can be connected to the Internet, and the analog camera cannot. What is the specific difference?

First, the concept should be clarified:

The front-end of the analog camera uses a line-by-line scanning CMOS/CCD sensor to convert the optical signal into a analog electrical signal and then output it to the DSP, the DSP performs A/D conversion and color adjustment, and then converts D/A to a pal/ntsc TV signal output.

A Network Camera is a new generation of cameras combined with analog cameras and network technology. It has an embedded chip and uses an embedded real-time control system. After video signals sent by cameras are digitalized, they are compressed by efficient compression chips and transmitted to Web Servers through the network bus, authorized users can watch, store, and manage video data locally or remotely through a standard IP-based network infrastructure.

Second, the performance is different:

1. Definition. Clear is the goal pursued by every user and the ultimate mission of the security industry. The clarity of network cameras and analog cameras is incomparable. Currently, network cameras can output images of millions, 2 million, 5 million, or even 10 million pixels, while analog cameras can only output images of CIF and D1.

Second, integration. The built-in Operating System of the Network Camera allows you to manage and view images using a scale WEB browser on any PC. It can also be shared with multi-screen management software to achieve multi-channel monitoring, there is no limit on the number of channels without increasing the hardware cost. The analog camera must be connected to the DVR, and the number of DVRs must be limited. After the DVR is fully connected, the hardware cost will be increased when the camera is added.

Third, management differences. The built-in WEB of the Network Camera allows you to manage and view images using a PC-scale WEB browser. At the same time, the Network Camera can also achieve Remote Management and image viewing, and store the image data on a remote hard disk, which is easy to search, easy to store, and will not be damaged; the simulated camera is a relatively blocked system, which can only be monitored internally. It cannot be monitored remotely. The video data can only be stored locally or remotely, which is easily damaged by criminals.

4. Install the camera. A Network Camera only needs to connect to the nearest network and assign an IP address. It can use the existing network as the transmission platform without wiring. The analog camera needs to connect the coaxial cable to each camera and connect to the control platform, video equipment, and display equipment, re-wiring is required for each added route, and there is no ready-made network available for use.

Fifth, capital consumption. The cost of network cameras for high-quality network cables is usually 30% to 40% less than that of coaxial cables of the same scale. A network cable can support hundreds of network cameras and other devices at the same time; each analog camera needs a cable. If there are multiple cameras, you must purchase many cables and spend money on installation and deployment of these cables, in general, labor and maintenance costs are high.

Sixth, remote monitoring implementation. Network Cameras can be remotely managed, such as video settings, cloud platform control, alarm settings, two-way intercom, and advanced management. analog cameras can only watch images locally for management.

We can see from the comparison of the above several aspects that the Network Camera is superior to the analog camera in many aspects, but this is not absolute, and the Network Camera has a high requirement on the external environment, A very strict network environment is required, and network application environments in many parts of China still have some problems such as latency, disconnection, and congestion. In this case, the advantages of a simulated camera are highlighted. Therefore, in addition to considering your own needs, you must also properly assess your own environment to avoid unnecessary losses.

With the development of economy and technology, the price of HD network cameras is becoming more and more common. It is gradually replacing the traditional analog camera's high-definition Network Camera with its unique advantages, and will surely become the leader in the high-definition security surveillance camera.
