The difference between network cameras and analog cameras

1, the image

Network Camera : let people see more clearly , the goal is always the people , network cameras can reach 100w, 200w, more even 300w500wa800w pixel image output. Analog cameras : only do d1, cif output.

2 , management, monitoring

Network Camera : Built-in WEB, using a standard WEB browser on your PC , you can manage and view images. The ability to remotely manage and view images. Presence on the network camera can be remote image data hard drive, easy to find , easy to store, will not be destroyed.

Analog cameras : closed , only watch inside , not remote monitoring . Video data can only be stored locally , not remotely view , easily destroyed criminals .

3 , integration

IP Camera : Built-in operating system. Use either a standard WEB browser on a PC , you can manage and view images, and can be shared multi-screen management software , multi-channel monitoring, unrestricted ones . No additional hardware costs.

Analog cameras : analog cameras to the DVR (DigitalVideoRecorder meaning of digital video recorders, if only from the literal to understand, it does not specify the recording medium is a magnetic tape or hard disk. ) Is connected , DVR large ones have certain limitations , the DVR full access , an increase in radio as the first but also increase the cost of hardware .

4, the installation

Network Camera : Simply connect easily to the nearest network camera network and assign an IP address can be. It can use existing network as a delivery platform , not the go cabling.

Analog cameras : the coaxial cable to each camera , and connect to the control platform , video equipment, display device. Each additional way to be re-wiring , and no existing network can be utilized.

5 , remote

Network camera : can be managed remotely , such as: video settings, PTZ control, alarm setting , two-way intercom, upgrade management.

Analog cameras : only local viewing image management.

6 , the extension

ip camera : You can easily add more cameras to the system in which the network .

Analog cameras : Extended work very hard for each analog camera needs to have a dedicated cable when using long cables will affect the image quality.

7 , the cost of

Network Camera : The cost and quality of the network cable to the coaxial cable is usually higher than the standard 30% to 40 % less . One with a network cable to simultaneously support hundreds of network cameras and other devices. IP-based network infrastructure, often in the proper position , which means the cost for building the system can be reduced to only include the cost of the network camera .

Analog cameras : very expensive coaxial cable , commonly RG59750hms quality standard coaxial cable expensive than the 30% to 40 %. Each analog camera requires one with cable , if you have a lot of cameras , you have to buy a lot of morning cables and these cables are designed for installation and deployment of money. Higher labor and maintenance costs , in addition to the cost of the system will also include the construction of analog cameras , VCRs and tape costs.

In short, one-way analog cameras only transmit video signals , and its performance is subject to the level of DVR and operator , however, network camera can transmit full-duplex digital information , and the ability to effectively integrate with other devices within the system , to enable them to achieve a higher level of performance in a distributed , scalable environment . Network cameras can communicate in parallel with multiple applications to perform various functions , such as detecting the movement of the screen , or sending video streams in different formats and the like.
