The DVR will take 1 x SATA 3.5" drive of any brand.

It's worth checking with Y3K if it will be ok with a 1.5TB drive as sometimes the firmware of the DVR can have limitations on drive size.

I never buy the hard drives from Y3K, as they can be found cheaper from Ebuyer. CCL etc.

Cam, DVR & wiring kit is everything you need to get you up and running.

You will also need to connect the DVR to your broadband router with a cat 5 cable. As it's a 4 channel DVR you can always add up to 3 more cameras at a later date.
