How much A power does a general surveillance DVR need for 4CH 4T HDD?

The power of the video recorder is about 50 watts, the hard disk is about 10 watts, and if there are only 4 hard disks, the total is 90 watts, and the power supply of 150W can be.

1.The life of the hard drive.

Ordinary computer hard drives.

When the power is turned on, it will start at full speed, and the instantaneous current may reach 2 amps, or even higher. (Therefore, some customers use ordinary computer hard disks and can't read the hard disk when they turn it on, so they change to a high-A power adapter.)

After normal, customers can refer to this solution in actual use).

When the monitoring hard disk is booted, it will accelerate slowly, and the starting current will be controlled below 2 amps.

Because multiple hard disks are usually installed in the monitoring system, a large starting current will be generated at the moment of startup, and if it is an ordinary computer hard disk, the power supply will be difficult to bear, or even burned. In addition, the monitoring system generally does not have high requirements for the transmission speed of the hard disk, but it will frequently read and write small amounts of data. Therefore, it is necessary to optimize the structure of the head reading and writing mechanism according to the reading and writing characteristics of the monitoring system to prolong the life of the head.

The theoretical average trouble-free operation time of the monitoring hard disk is much longer than that of the ordinary computer hard disk, and the stability and reliability are higher.

2.Difference in continuous working hours.

The design of ordinary computer hard drives is based on 8 5. 8 5 refers to the hard disk of an ordinary computer working 8 hours a day, 5 days a week (hard disk work refers to the hard disk in a read-write state. It is important to note that there are two states after the hard disk is powered up:

The working state and the waiting state, where the working state is that the hard disk is doing read and write work, and the waiting state is that the hard disk is not reading and writing work but is in the standby state. )

Surveillance HDDs are designed and developed to meet the requirements of a 24/7 enterprise-class environment. 24 7 means working 24 hours a day, 7 days a week (i.e., continuous work).

In this case, it is best to be between 50,000 and 80,000, all without any problems at all, to achieve a very good effect, and there will be no problems.

As far as the description is concerned, the power supply is universal, the video recorder itself has a power supply, and the cable is plugged in. There aren't many sayings about a.

The hard drive itself doesn't consume much power, 15W at most.

I don't know how to continue asking, satisfied.

As long as the power supply you choose is between 50,000 and 12 amps, this situation will be perfectly fine.

In this case, the power consumption is not too large, and about five amperes of power are required.
