The following IP Camera settings are recommended for optimal connection with the NS Series
Setup Items Default
Network Type DHCP
Encoding Type CBR
Resolution 1280x720
Frame Rate 25fps
Bit Rate 2Mbps
Sub Stream CIF
512Kbps

The NSP Series features a "Plug and Play" function with a PoE Switch.
 The "Plug and Play" functionality requires the IP Camera to be in DHCP mode.

The NS automatically assigns an IP Address to the IP Camera. (10.20.30.11 ~ 10.20.30.254)

The NSP models will automatically map the camera on the PoE Port to the corresponding NVR
channel number.
With the NSP Models, it is prohibited to connect a router to the POE Ports to connect the IP
Camera, the NSP will not be able to find and connect to the camera. The LAN Port can be
connected to a router, but not the PoE Ports.
The IP Camera must act as a DHCP client for the "Plug and Play".
The "CBR" is recommended because of the internal buffer design of the NS Series
The maximum performance of the N16NS/NSP is 1080p@192fps or 720p@400fps.
To get higher frame rates per channel, 1280x720 is the recommended resolution.
The maximum performance of the N16NS/NSP is 720p@400fps.
Therefore 25fps per channel is recommended. (25fps x 16 = 400fps)
The maximum throughput of the N16NS/NSP is 40Mbps.
Therefore 2Mbps per channel is recommended. (2Mbps x 16 = 32Mbps)
For "Dual Streaming", the sub stream should be turned on.
And for the proper streaming through the WAN connection,
CIF@512Kbps or lower bitrates per channel is recommended.
