    • Dear anil,
      There are several things you need to confirm:
      1. Confirm whether the device is connected with network.
      2. Go to network setting , in TCP/IP enable dhcp option , the ip address will be changed to the router segment.(Just confirm the router can assign the IP to the device,and the IP segment of the device and router lan port are same).If you enable DHCP ,but your device ip cannot be assigned as the ip, whose segment should be same as the router lan ip segment. Please check the wiring of the network cable.
      3. Confirm the main DNS is;Sub DNS is
      4. Confirm the SN is not showing in zeros i.e (0000000000).
      5. Confirm the system date and time is correct on the recorder.
      6. Go to router configuration ,check whether there is some limitations in DHCP list.
      7. Upgrade the recorder firmware.
      8. If your recorder has dual network card,please confirm the ip segment of default network card is same as your router lan ip.
      We have to login on router to confirm whether ip address is found in dhcp list of router, then check the security settings.Here are steps:
      1. Fill the user name and password of router.
      2. Go to security settings > firewall
      3. Select the low or off option and confirm the status of p2p.
      If still having questions, you can contact the local technical support. Hope it helps!
