Thanks for the advice, I had already ordered the cameras and NVR, after a phone call today I asked them to replace the 4 channel with the model you mentioned. They have done this for me.

Hi, Looking to purchase Hikvision NVR DS-7604 NXI-KI / 4P 2 TB Hard drive, with 3 DS- 2CD2386G2-ISU-SL 4mm, 8 MP and 1 DS-2D2386 G2-ISU/SL 2.8mm 8MP for my 3 bedroom house, is this a good setup? Thanks. Around £800. Apparently Dark fighter cameras.
