I picked up an 8 channel Eyesurve ION NVR from Nelly's to run as a back up to my Blue Iris machine and have to say that I am really happy and impressed with its performance. I'm recording 7 Hikvision cameras 24/7 (5 2032 bullets, 1 exir and 1 cube). This NVR is compatible with Hikvision, EYEsurv and Dahua IP cameras but currently does not record on motion with Hikvision cameras. I picked up a 3 TB hard drive and a cheap wireless mouse to compliment it and so far this little guy has been perfect! I highly recommend it as a backup NVR. It is small and easy to hide and also has an Android an iPhone app which allows you to view recordings and live cameras. It needs to be plugged into the wall for power and also into your router / switch. Currently the NVR does not record in 3MP but it will in 1080P.

All it requires is power and internet access via hard wire (regular RJ45 connector).
