6. Check your e-mail account to see if you received the test message. If test e-mail was received successfully, click Apply to save the settings.

it’s the theoretical value

The capacity of storage space should be calculated according to the days, bit rate and type

1.Bit rate: 2Mb (for example)

1.Bit rate: 4Mb (for example)

2.Bit rate: 6Mb (for example)

Note：these tables are only for reference, and the actual values have the redundant.

Full duplex : 

Data communication allows data to be transmitted in both directions simultaneously. Like the switch or telephone, The network card can also receive data while transmitting data, and the two are synchronized.

Half duplex:

Data transmission allows data to be transmitted in both directions, but at a certain time, only data is allowed to be transmitted in one direction。 like Walkie-talkie

YES, it can be done like this.

However, 265 encoded video can only be realized when accessing the H.265 camera, saving space. If the H.264 camera is connected, this function cannot be realized.

1. NVR+HDD: the NVR is connected to the network camera, it is recommended to fix the IP address of the NVR. In the system configuration, network configuration, basic configuration interface, do not enable automatic acquisition of the IPV4 address, manually assign an IP to the NVR. In this case, in the case of an external network interruption, as long as the LAN is connected [the network between the camera and the NVR] without interruption, the recording will continue. The NVRis connected to an analog or coaxial camera, and whether the network is connected does not affect the recording.

2. IP Camera +SD card:  the external network or LAN interrupt will not affect the recording.

1. please make sure the power supply is stable, or you can change a new one

2. if the NVR stop at the booting screen, maybe the main program(firmware) has the problem ,please contact the tech support to check it remotely .

3. If the NVR restart automatically, please update the firmware to the latest version.

1. Camera power supply is unstable, test with new power supply.

2. Network cable Problems, or Check Switch Ports, or Replace new Switches.

3. Restore factory settings or upgrade new programs.

1.One network port connects the camera and the other one connects the router connecting the external network.

2.Or one network port connects the IP address of one segment and another network port connects the camera of another segment.

NVR with two network ports can set different IP addresses for two network ports.

Whether you want to use it or not depends on your own situation.

1. Sample information

2. Network setting

Please enter the valid values:

3. Check the status of Upnp option

If the Networking setting and router setting are correct, the Upnp will get the current ports, too.

Otherwise,if you get “0” for each port,please check your network and router setting.

4. DDNS

Enable this option and then select the proper protocol you want：

1) sunellddns

enter a name, then click [Test]

If it shows “Test successfully ”,

Then you can enter “dvr238.sunllddns.com:1230” in IE broswer

Note: 1230 is the HTTP Port in the option “UPnp”
