All these NVR's are similar (white plastic box):
DH-NVR4108 / DH-NVR4104
NVR4108-P / NVR4104-P
DH-NVR1104-P
NVR1108-P
Some are 4 channel (4 camera) and some are 8 (the last number in the model number).
What I don't understand is, some have "DH" in the model name (and some don't). Some have "-p" in the model name (and some don't). And some are "410x" and others are "110x". What is difference between 41xx series and 11xx series? I think -P might be for PoE.
And the following are black box chassis (metal?):
NVR4104H-P (1 sata port, 4 cameras, 4 PoE)
DH-NVR420x (2 sata ports, x = number of cameras 8/16/32)
So the difference in the above 2 are clear (4 camera vs 8+ cameras, 1 sata vs 2 sata). Again one is "DH" and the other is not.
Lowest price "black box" NVR4104H-p (4 camera) is same price as "white-box" NVR4108-P (8 camera).
Do "black box" models have better performance?
Some model have in the name "DH" and some don't. Does that mean anything?
DH-NVR4108 / DH-NVR4104
NVR4108-P / NVR4104-P
DH-NVR1104-P
NVR1108-P
