Sunell NVR Guide

Hard disk or unable to record video

1. Make sure the hard disk is well (check by replacing with another new one)

2. When hanging with multiple hard disk, note that the power supply can meet the requirement, monitoring specialized hard disk is more stable with smaller starting current, lower working speed and consume less power than consumer hard disk, if power supply is not enough, the hard disk will not be able to work, which result in disk unrecognized and recording failure.

3. If NVR can read the disk, please format the disk first, as in most cases, repeating read and write will generate disk fragmentation or bad sectors, a formatting process will skip or repair the bad sector.

What is the IP of NVR?

Default IP of NVR is 192.168.0.121

Is it possible to add third party IPC to Sunell NVR?

Yes, it is accessible for those third-party devices which support ONVIF protocol.

NVR can not acquire the IP address automatically?

Please the NVR to Router, and make sure the function of router is enabled,and open the function of automatically getting IP on NVR network setting menu

How to get RTSP stream from NVR?

RTSP format: rtsp://ip:port/snl/live/cameraid/streamid

Example: rtsp://192.168.1.19:554/snl/live/1/1

NVR can not add POE ?

1. please check if the username and password is correct when adding the camera

2. network cable issue, please use CAT5e or CAT6e cable, It is recommended to use 8 cores for the wire, the POE cable sequence for data transmit is 1/2/3/6, for positive power is 4/5, for negative power is 7/8, the distance of cable should be controlled around 70 meters

3. camera is not powered on, please check if camera support POE

NVR can not find the IP of camera?

If camera is sunell camera, and you don’t know the ip, please connect camera and PC at same local network(or directly connect camera to PC), using IPsearch tool to find the correct IP, then add it to NVR; If camera is from third party, please check if they provide tool to search the camera IP, Then add it to NVR by input the IP, user name and password of camera

IPC often shows offline on NVR?

1. Power supply of IPC is not stable, for example, IPC will consume more power at night with IR Led enabled, which may cause electricity insufficient.

2. Network bandwidth issue, the switcher performance is insufficient

3. Camera issue:

If only the specified camera or channel has this issue, we recommend you replace with a normal camera to check

If offline issue happens randomly with all channel, we suggest checking reason 1 and 2

If offline happens to all channel at same time, please check if the camera is powered by centralized supply, please check the power status

Where to add other users account and what authorities can be set?

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.

Can NVR connect to wireless network?

NVR generally does not support wireless connection. Usually It is also possible to link routes or switches through network cables, or to connect directly with cameras using network cables.

What to do if the registered camera on NVR often drops off?

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 or new programs.

What to do if the NVR can’t startup?

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 tech support to check it remotely.

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

Can the device continue to record when the device is disconnected to network?

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.

Can H.265 and H.264 cameras connect to NVR with H.265 at the same time?

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.

How to calculate video storage capacity of HDD?

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)

channel and time Disk space   required
1 channel for 1   hour 2048Kb/8Byte*3600sec*=921600KB=900MB
1 channel for 1   day 900MB*24=21600MB≈21.09GB
1 channel for 30   days 21.09GB*30≈632.81GB
16 channel for   30days 632.81GB*16≈10125GB≈9.89TB

1. Bit rate: 4Mb (for example)

channel and time Disk space   required
1 channel for 1   hour 4096Kb/8Byte*3600sec*=1843200KB=1800MB
1 channel for 1   day 1800MB*24=43200MB≈42.19GB
1 channel for 30   days 42.19GB*30≈1265.7GB
16 channel for   30days 1265.7GB*16≈20251.2GB≈19.78TB

2. Bit rate: 6Mb (for example)

channel and time Disk space   required
1 channel for 1   hour 6144Kb/8Byte*3600sec*=921600KB=2700MB
1 channel for 1   day 2700MB*24=64800MB≈63.28GB
1 channel for 30   days 63.28GB*30≈1898.43GB
16 channel for 30days 1898.43GB*16≈30375GB≈29.66TB
