A:AnswerMost Night Owl DVR/NVRs can accommodate larger hard drives. See your product Specifications for the max size. Our DVR/NVRs are compatible with internal SATA HDD's, 2.5" or 3.5". The HDD should have a minimum of 7200 RPM. We are not able to guarantee compatibility with external hard drives at this time. Thank you for choosing Night Owl!
