CCTV Camera Pros stand alone DVRs and PC based surveillance systems include either a 500GB or One Terabyte (1000GB) SATA II hard drives* HDD (*SATA III on 2TB HDD). To accommodate varying video surveillance needs, CCTV Camera Pros supplies additional and or upgraded hard drives for our stand alone DVRs and PC based surveillance systems.
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.
