After a couple of break-ins on the next part of the estate, I'm thinking about getting round to getting something purchased and installed.
Ideally I wanted something like HikVision Colourvu with full night colour vision. I think I only really need 3 cameras, one of the front, one for the back, and one for the side of the house, but also thinking I could have 2 at the front, with one on the door/house, and one for the driveway. I know the 8mp (4k) ones are probably the best on the market, and I saw a couple of bundles
https://www.ebay.co.uk/itm/358337182010 - 8mps, 4 cams, DVR and a 2tb HDD (with all the cables) for £419.75
or
https://www.ebay.co.uk/itm/126667211400 - 5mps, 4 cams, DVR and a 1tb HDD (with all the cables) for £299.00
I'm leaning more towards the 8mps, but do I need to have more HDD space than 2tb with 4 cams? Also, can I blur out certain areas with these, so I'm not recording neighbours houses etc?
