    SD card. Streaming Network Connection and Device Search This section details how to connect the NVS-33 to a network with or without a DHCP server, and describes how to acquire the NVS-33’s IP address. Connecting to a DHCP Network (DHCP Mode) Follow the following procedure to scan your DHCP network for connected NVS-33 devices.

  • Page 18: Connecting To A Non-Dhcp Network (Static Ip)

    Connecting to a NON-DHCP Network (Static IP) Upon connection to a non-DHCP network, the NVS-33 will not be assigned of any IP addresses. As such it is recommended that you manually assign a fixed IP address to the device or use the default IP address (192.168.1.60).

  • Page 19: Troubleshooting The Network Connection

    The IP address should be the default IP which is 192.168.1.60. Troubleshooting the Network Connection Connect the NVS-33 to the network and open the IP Finder utility program. Scan for the device. If not found, it is possible that your network is not assigning IP addresses.
  • Page 20 Make sure no other devices are connected to the LAN (wired or wireless) because this may result in IP conflicts. After trying all methods and if the problem is still not solved, the NVS-33 video streaming server offers the fixed IP feature that allows you to establish direct connection to the NVS-33.
  • Page 21  The NVS-33 should now be connected with an IP address of 192.168.1.60. If the NVS-33 still cannot connect, simply restore the NVS-33 to the factory defaults. Turn off the NVS-33.
  • Page 22 NVS-33 to 10.10.1.X, which can range from 10.10.1.2 to 10.10.1.255. Pick an unused IP address.  DHCP：Disable  Static IP：X.X.X.Y；the first three decimal numbers must be the same as your router or switch. The number Y must be a number not used by any devices connected to the network.
  • Page 23 MAC address starts with 00:07:36:03:xx:xx.  On the command prompt (terminal on MAC OS), enter "arp -a" then press enter key to display an ARP list. See if the NVS-33 is successfully connected to the network.  Execute services.msc，and on the right column of the “Services” window, locate “DHCP Client”...
