Due to every IP camera will provide different image to NVR and also request different bandwidth. So, when the IP cameras connected, you can check the IP camera connection status in NVR web page to adjust the IP camera configuration. The maximum aggregated bandwidth for NVR-420 is 40Mbps (including incoming/outgoing bandwidth). When the bandwidth is over 40Mbps, recording frame rate will be reduced. When this situation happened, you may configure the connected IP camera settings on NVR to reduce the system loading.
Step1. Please remove all the data on the USB flash. Then put the firmware (*.bin) in the root index of the disk. Rename the firmware as "firmware.bin"
Step2. Remove all the wires connect to the NVR-420. Plug the USB flash. Press the reset button and connect the DC power.
Step3. Hold the reset button till all the LED on front panel light in green. Release the reset button and wait for few seconds. You will see all the LED on front panel are blinking green. It means the upgrade is in process. When the blinking stop, the NVR-420 will be reset to default. Please use the utility to connect and login by admin/admin and check the firmware version again to confirm the upgrade procedure.
Step1. Unplug the DC power. Press the reset button on the back panel.
Step2. Hole the reset button and connect the DC power
Step3. Keep pressing the reset button till all the LED on the front panel start to spark.
Step4. Release the reset button; wait while the LED starts sparking. Then the process is done and the device will be reset to factory default.
Maybe the NAT router does not support the UPnP function. Please check user’s manual of router and turn on the UPnP function.
Check the IP address of device by using the PLANET IP Wizard II program or by UPnP discovery or set the device to default by the Reset button.
The device uses Category 5 UTP cable allowing 10/100BASE-TX networking within 100 meters.
The maximum number of users is limited to 20. However, it also depends on the total bandwidth accessed to this device from clients. Therefore, the actual number of connected clients varies depending on streaming mode, settings of resolution, codec type, frame rate and bandwidth. Obviously, the performance of the each connected client will slow down when many users are logged on.
