Hard Drive for Surveillance and CCTV

 Security is critically important and with celuoid and Video cassette tapes becoming extinct, it was only natural that CCTV and Surveillance recording with become completely digital. More and more cameras are popping up in cities across the globe and all those hours and hours of footage needs to live somewhere.

More so, it has to be stored somewhere that is readily accessible at the touch of a button, or else what good is days worth or recording without the means to efficiently access it in real-time. Hard Drive manufacturers realised this fact a long time again and have been producing Hard Drives specially designed for Heavy Writing (the act of recording data to a disk) and Heavy Reading (the act of accessing and retrieving data from a Disk) symultaneously or more one than the other!

Use our Hard Drive selection tool to help you select the correct Digital Surveillance drive for you. First you will need to Choose Direct Attached Video recording (often referred to as Wired Cameras) or Network Attached Video recording, which is when the data is being recorded via camera but sent to the recording device that houses the hard drives, over the network/internet.

What is the Difference between a normal hard drive and surveillance hard drive?

Why upgrade the Hard Drive in your DVR?

There are several variables which play into requiring larger storage capacity in one’s DVR:

1. The number of cameras you are using will affect the appropriate DVR or NVR hard drive size.

2. The resolution of these cameras (low, medium or megapixel), the higher the camera resolution, the better the video quality, and this will increase the storage requirements.

3. The Frames per Second rate you select for each camera (7.5, 15, 20 or 30 fps), for the higher the frame rate the more storage is needed.

4. The length of time you wish for the DVR to record (one, two, three weeks or more). Once you have assessed the number of cameras, the resolution and frame rate, determined how much time you can record before the oldest day is deleted, you will be able to decide which size hard drive is best for your video surveillance needs.

Key Advantages of CCTV video surveillance hard drives

  • Hardware Compatibility tested
  • 7200-RPM performance.
  • SATA 6Gb/s interface optimizes burst performance
  • High performance drives deliver dependable performance, even with hard drive track widths of only 75 nanometers.
  • New generation drives boosts overall performance by as much as 45% over previous gen.
  • RoHS directive on hazardous materials and voluntarily restrict halogen compounds
  • 70% or more of the materials used to build drives are recyclable
  • Low power consumption


What can I do to improve storage capacity?


Customize each camera’s frame rate down to a rate the your are comfortable with. Reducing the FPS (Frames per Second) to 7.5 to 15 FPS from 30 FPS will substantially increase the recording time, without reducing your quality.

There are several exceptions to this, for example, if you are monitoring cashiers or capturing license plates on moving cars, we recommend that you record at the highest frame rate possible, which is 30 FPS for most DVRs.

  • If the involvement is less than 10-12 cameras, then analog camera installation along with a DVR is recommended.
  • If the installation requires more than 15 cameras, then it is better to go for IP cameras and utilize an NVR. This offers a good scope to upgrade in future.
  • If the installation involves large number of analog and IP cameras, it is better to use a hybrid NVR, which can entertain analog and network camera recording.
  • For all large scale installations taking place in public places like airports, bus transit facilities and such, it is better to go for IP camera installations. But usually, we observe that the IT head carries out the surveillance operations with a mix-up of analog and IP camera involvement.
  • To be specific, almost 4-5 years ago, all large or small scale surveillance installations had analog cameras in place. But due to the development in technology and utmost benefits, a trend for IP cameras is now being observed. Therefore, in order to keep up with the current trend, surveillance managers are either replacing their equipment with IP from analog or trying their best to integrate both technologies with the help of hybrid NVRs and video management systems.
