Hard drives bring protection and reliability.

If you have the urge to record 24/7 live footage, you need more cameras and more storage for your digital security video recorder with a surveillance hard drive.

Surveillance hard drives are designed and manufactured exclusively for 24/7 high definition (HD) video surveillance security systems either in your home or business.

A surveillance hard drive cannot be compared to a regular hard drive on your computer. It is used in the surveillance camera for storing 24/7 surveillance videos. Therefore, it plays the most important role in your security device.

Have you ever imagined a surveillance camera without a hard drive for storage?

Although they usually come pre-installed in the (NVR) or the (DVR) of most home security cameras.

However, an external hard drive can be installed on an NVR or DVR to get more storage space.

Over the years, the improvement of CCTV surveillance has increased by leaps and bounds.

Having a security camera in your home is one of the best forms of ensuring the safety of your family and property, and you need enough storage space to store these video recordings.

Do you need a hard drive for security cameras?

Today, you can monitor your home or office live from your smartphone with clear video quality and other great benefits. But, if you don’t have a CCTV storage system, where can you store all your moving videos for playback?

So it needs to be connected to a hard drive that is designed for surveillance cameras. Otherwise, it will not be able to record the videos.

If you want to have a set of 3 to 4 surveillance cameras for continuous recording, you need to buy a surveillance hard drive. If you have more than 4 surveillance cameras, a surveillance camera DVR or NVR with a hard disc is preferable.

Now that you know that computer hard drive and CCTV hard drive are not the same. We have made choosing the best hard drive for a DVR security system easy and fun for you.

Surveillance Hard Drives Vs. Normal Hard Drives

You can’t use a regular desktop hard drive for your surveillance system. You may feel that all hard drives work the same way, but that is not true. Traditionally, a desktop hard drive is designed to operate normally for 8 hours.

So the total utilization will be 10-20% at most. That’s low performance.

On the other hand, the hard disk of a surveillance system plays an important role. It forms a central component for the digital storage of video surveillance systems.

It works around the clock and can be used in a DVR, NVR, video server, or video management system. To remain always active in your surveillance system, these hard drives must always be active.

We recommend using a separate surveillance hard drive or a professional quality hard drive for your surveillance system.

For example, use a DVR with a built-in surveillance hard drive for the scale of a video surveillance system equipped with a pair of HD cameras.
