Smart home is more and more widely used in families, which can allow homeowners to monitor the security of home or control home equipment 24 hours. Therefore, there are more and more home monitoring systems installed in Shenzhen. Home monitoring systems can generally be divided into two types: 1. Video capture card + computer + camera head, 2. Hard disk video recorder + hard disk + camera + display. Here are the advantages and disadvantages of these two methods.

1. This method is to have a computer at home as the storage host and an acquisition card as the back end. The advantage is that there is no need to configure a hard disk video recorder for storage and save a sum of money. The disadvantage is that if you need 24-hour monitoring, the computer needs to be on for 24 hours. Over time, the hardware loss of the computer is very serious, and the maintenance rate is also very high. One is that the video stored in the computer hard disk will be lost (the acquisition card may be incompatible with the computer due to looseness or computer poisoning, which will invalidate the monitoring). The biggest difference between video capture card and hard disk video recorder is that when video capture card encounters multiple images, its stability and picture quality are not as good as hard disk video recorder; Compared with the acquisition card, the hard disk video recorder has more stable performance, more related functions and convenient operation.

2. When it comes to power consumption, the average household computer consumes about 300W an hour. The power consumption of hard disk video recorder is less than 100W an hour. If it takes a long time, it will save a lot of power than using a computer. The first method is to save money when installing it, which is hard and expensive to use. The hard disk video recorder is more expensive when installed, but it is convenient, convenient and economical to use.

The home monitoring system can also do remote monitoring, but it must be Netcom ADSL, and the community broadband can not do remote monitoring basically, because the port of the community will not open the port for a certain owner alone. So it must be ADSL. Because the upload rate of ADSL we use, whether 2m or 10m or optical fiber, is only 512k / s. therefore, it is best not to have more than 10 cameras in the front section, otherwise it will be very jammed when watching remotely. If you turn down the code stream, the card will be lighter, but the definition will be reduced. Therefore, the installation of household monitoring must understand some basic adaptations in order to achieve the number in mind.
