There are hard disk video recorder also need video server, what is the difference between the two, do a large monitor with which
DVR and video encoder principle is the same, are analog video signals into digital signals, easy to store;
The difference is: 1. DVR generally comes with a hard disk interface for front-end storage architecture;
Design large-scale monitoring, then look at the budget and network layout: relatively speaking, hard disk video recorder front-end storage model, the cost will be lower, the network pressure will be relatively small; video server as a result of centralized storage, the network requirements will be higher The On the current video surveillance network, digital trends, the video server or network camera is the first choice, improve image clarity, more convenient for future expansion.
2. Video encoders generally do not have a hard disk interface for more centralized storage architecture.
