Gav couldn't see a link to the home security on your post here it is: Swann DVR8-1425 8 Channel D1 Digital Video Recorder | Computers & Tablets, Computer Accessories : JB HI-FI
Good advice on the UPS very important if you want to have your videos streamed to the internet.
you may also want to check my thread: Swann Recording Kit SWDVR-4150WH + 500GB HD and 4x PRO-510WT Cameras cheap home security! it's not quite as good but even with the JB Hi-Fi coupon it's almost $200 cheaper.
It only has 4 cameras and a 500GB HDD but if you stream it to cloud storage or a bigger drive in your computer it won't be a problem.
