Do you need a Hard Drive for CCTV?
If you wish to record footage, which many users do, then the answer is yes. Whilst you can run a NVR or DVR without a hard drive, if you're looking to record or perhaps hand footage over to the police then your camera pictures will need to be stored on a hard drive for direct viewing on a screen, after an event. But what else do you need to know? Using a PC Hard Drive could be feasible, but different brands create a range of drives for different applications. A CCTV hard drive runs different demands over long periods of time, whereas a PC hard drive typically does not. Depending on your use case, a server-spec hard drive that is built to last in a server environment may be more suited to your specifications. Motion-detected recording is a standard feature on all modern DVRs/NVRs. Using motion detection can use a large amount of disk space over a longer time period, especially when there is minimal activity. You can adjust on a per camera basis the sensitivity and even draw up a grid over the screen of the camera to block off areas which will reduce false triggers. You can also set up email/mobile app alerts when motion is detected, this pixel analysis can result in false triggered recordings, yet is a quick way to save hard drive space.
