I am wanting to get the Swann SWNVK-1685816 16-camera system, but I need it with (6) SWNHD-885MSFB, (5) SWNHD-885MSB, and (5) SWNHD-886MSD cameras. Anyone have any luck getting any cameras other than the standard ones that come with the package? I called their support line but they tell me it's not possible. If it's not possible, can someone point me towards something similar that I can piece together for around the same cost point? Swann's system is currently $1800 and the additional cost of some of the cameras would be 120. There' a coupon code for first-time orders for 10% off, so total price would be somewhere around $1750.
