We supply AV grade hard drives. Although a SATA fitting, the same as a normal computer hard drive our AV grade hard drives are specifically designed for use in DVR recorders which run 24 hours a day and fill up 100%. Remember that when you order your hard drive at the same time as a DVR the price includes fitting the drive into the DVR, formatting the drive and configuring the DVR so it is plug and play on arrival.
250GB is our entry level hard drive. Suitable for systems where only a single camera is being used or storing footage isn't important. We suggest 250GB per camera when choosing which drive to have fitted in your DVR. This gives approximately 3 weeks rolling footage at D1 resolution with typical settings
