A hard drive in this DVR is almost a must to enjoy the full potential of the system. If you can operate a screw driver you can install the hard drive. I would recommend getting the hard drive from Security Camera King as it is good to go right out of the package and you can be assured it will be compatible with their DVRs. Trying to determine what size hard drive to install is a bit over whelming working the formulas but if it will help, I am operating 6 cameras on motion record at a commercial property, recording for a week now and it is not even close to full. The support staff at Security Camera King is why I chose this system and they have fixed my problems and suggested other features and then set up those features on the same call.
This is a good hard drive and adds a lot of storage capacity for me. If you are a do it your selfer like me, remember that if you see hard drives of the same capacity that our cheaper, make sure you check their speed because these drives have to be fast.
This is an INTERNAL hard disk drive. It works great. It's dependable, has a relatively fast data transfer rate, and fits all of Security Camera King's DVRs. If you decide to add it on after your original DVR purchase it is rather easy to install too.
