Possible causes:

1. Player is not installed correctly.

2. The file system error of the backup U disk or removable hard disk.

3. Graphics speed up software whose version is above DX8.1 is not installed.

 

Ø How to do NVR firmware Update

For access to some functions and requirements, NVR needs to update firmware.

Before update, users need to prepare as below:

1Ј© To check Serial No.: SettingЎъDeviceЎъDevice info;

2Ј© To check Master Version: SettingЎъDeviceЎъSystem info;

3Ј© Unplug network cable;

4Ј© Restart NVR;

5Ј© By providing Serial NO., Master Version, PCB and Rear Panel Pictures, users can get the accurate update files;

Update Operation: SettingЎъSystemЎъUpdate, click Ў°BrowseЎ±, choose U diskЎЇs .update suffix update file in root catalog, click Ў°updateЎ±, during updating, please do not cut off electricity or carry out other operation in case that update failure leads to repairing.

 

Ø Image preview or playback abnormal,

4 kinds of ordinary situations as below,

1) IP Camera IP address can be searched, multi-images sub stream and single image main stream all cannot have image;

2) Single image main stream has image, multi-images sub stream is on black screen;

3) Multi-images sub stream has image, single image main stream is on black screen or still image as well as black-screen playback;

4) Image or screen crashes

To choose mode is very important when NVR can be access to different brand and different resolution IPC.

 

Above 4 kinds of malfunctions are very common in real utilization and this is all following the steps: SettingЎъDeviceЎъDevice infoЎъStream type.

The first 3 numerical values must be matched with IPCЎЇs stream setting. IPCЎЇs main stream, sub stream and reference frame must be equal to or less than the numerical values of NVRЎЇs stream type. Stream type adjustment need to be saved and restart to make it effect.

The first numerical value of stream type Ў°mainЎ± represents the IPC accessible channel numbers and main stream resolution ratio; The second one Ў°subЎ± is subs streamЎЇs resolution ratio; The third one Ў°refЎ± is the reference frame IPC can get access to; The fourth one Ў°playЎ± is the playback channel numbers under this kind of stream type.

Solution of 1st situation which IP address can be searched but without any images:

1Ј© Adjustment of stream type, choose stream type with ref value for 4ref. To get access to Ambarella solution IPC needs 4ref;

2Ј© IPCЎЇs username and password should be correctly filled in;

3Ј© This IPC has not been butt joint or version outdated, which needs supplierЎЇs confirmation for butt joint and then update NVR firmware.

 

Solution of 2nd situation which single image main stream has image and multi-images sub stream is on black screen:

1Ј© Adjustment of stream type, choose stream type with sub stream of 720ЎБ576, please be aware if main stream resolution ratio and IPCЎЇs are matched;

2Ј© By IPCЎЇs IE(IPC IP address access) or PC Client, users need to adjust IPCЎЇs sub stream for resolution ratio of VGA or CIF;

3Ј© To update NVR firmware.

 

Solution of 3rd situation which multi-images sub stream has image and single image main stream is on black screen or still image as well as black-screen playback:

1Ј© Adjustment of stream type to 1080P mode;

2Ј© By IPCЎЇs IE(IPC IP address access) or PC Client, users need to adjust IPCЎЇs main stream with resolution ratio for 960P or 720P;

 

Solution of 4th situation which image is crashed is same as 3rd situation; If the whole screen is crashed, it may be connected with NVR hardware malfunction or lunk. Please check if monitor resolution ratio is matched or exchange of another monitor and lunk.

 

Ø Images cannot be all connected in full channel, image off or image sporadic

1Ј© Stream data access exceeds NVRЎЇs total network resource, 3M for main stream and 512K for sub stream recommended;

2Ј© NVR firmware outdated and needs to be updated with optimized network master version

3Ј© Ethernet switch backplane bandwidth is deficient. NVR of more than 16 channels in number needs to get access to a Gigabit Ethernet switch higher than 48G in Gbps.

4Ј© Carefully check out IP address is conflicted or not. If there is device sharing the same IP address with NVR local IP address in network, it happens to have image flickering every second. Properly it may have such a phenomenon that image occurs in 1st channel and next second in 3rd channel, then next second has no idea in which channel.

Ø Audio fails to monitor

1) IP camera audio enable or not: check out and open up audio to see whether IP camera has BYO pick-up via IE or IP camera BYO client app on PC;

2) Audio format: adjust audio format to G.711 via IE or IP camera BYO client app on PC;

3) NVR: Setting---Channel---Video Parameter, choose the corresponding channel and change stream type to Video & Audio;

4) Whether Aout port on NVR rear panel gets access to speaker working properly.

 

Ø New HDD added but video still recorded in previous HDDs

1) Formatting all HDDs;

2) Shut down and unplug former HDDs, then only insert new HDD and after half an hour recording, shut down and insert the former ones.

 

Ø IE access: fail to install plug-in without image out

NVR: Setting---Network---Network Setting, check out IP address, Remote Port, HTTP Port.

First to fix LAN access:

1) WinXP: Please install VC++2008 from Microsoft;

2) Win7 & Win8: Click Ў°StartЎ± to choose current login user as Ў°AdministratorЎ±, tick Control Panel---User Accounts and Family Safety---Change User Account Control Setting, then lower down to Ў°Never notifyЎ±. Open IE browser and press Ў°ToolsЎ± to see Ў°Internet OptionsЎ±---Ў°SecurityЎ±---Ў°Custom LevelЎ±, adjust ActiveX controls and plugins to Ў°EnableЎ± or Ў°PromptЎ± and Ў°DisableЎ± Ў°Binary and script behaviorsЎ± alone. Follow the same setting step in Ў°Local IntranetЎ± and tick Ў°OKЎ±, restart IE browser. Finally press Ў°AltЎ± to see Ў°ToolsЎ± and tick Ў°Compability View SettingЎ± to check Ў°Display all websites in Compability ViewЎ± . Click Ў°OKЎ± and reopen IE browser.

3) Check whether PC had installed ActiveX in previous time. Close IE browser and go to Ў°Program Files[WinXP]Ў± folder in C Disk, then delete Ў°dvr_activexЎ± whole folder, while deleting Ў°dvr_activexЎ± folder in Ў°Program Files(x86)[Win7&8]Ў±, then install new activex.

4) After successfully installing activex, input NVR IP address on IE browser address bar and login interface appeared. Port for NVR Remote Port as default is 5050 in port, admin in user name and no password. Tick Ў°loginЎ± and click right mouse to see Ў°Open AllЎ± or tick the ЎБ to ЎМ in every screen right corner.

WAN Access:

Recommend to shut down NVR and close routerЎЇs UPNP, then do the port mapping. If open UPNP without NVR shut down, it may have mapping conflict and NVR UPNP is default to be closed.

If users have static IP, it needs to map two rules in router, first is 5050-5053, related to NVR IP address; second is 80(Strongly advised to alter), related to NVR IP address, then succeed to finish port mapping.

Some Routers can only do the port mapping one by one, which needs to map 4 ports: 5000, 5051, 5052, 5053, plus HTTP port, otherwise it may occurs that user can get access to login interface but fail to get image. For mobile access, user needs to plus 3 based on the remote port.

Open IE browser again and it can be access to input static IP address in bar. If you have changed HTTP port from 80 to 88, you must input http://static IP:88 (colon : is English character)

If users donЎЇt have static IP address, after port mapping, it needs to do dynamic domain name blinding. Like 3322, Peanut Hull, No-IP, after succeed to register domain name on their websites, tick NVR Setting---Network---DDNS Setting, and fill the username, password and domain name.

 

Ø How to apply P2P cloud surveillance

1) To check whether your NVR has P2P, tick Setting---Network---Management Plat_ and check whether there is Icloud protocol on the column. If not, NVR needs to be updated with firmware;

2) NVRЎЇs network cable should be access to public network;

3) Smartphone is necessary to download software and install Ў°goolinkЎ±, which can be found on Android market and App store. For IE end P2P, open IE browser and input http://www.goolink.org on address bar and then register an account. After successful registeration, refresh http://www.goolink.org and after activex is successfully loaded, it will have a black screen in the middle of the page. Now users turn to add device in device management and device ID is from usersЎЇ NVR Series No. while device user is Ў°adminЎ± with no password. Users can manually set up device name by them self. If users had changed password already, pls fill in the right password. Channel number is according to the nvr users at hand, which max supports 32 channels. After all this, tick Ў°addЎ± and go to see live preview.

4) After software installation, tick the left corner Ў°+Ў± button and choose the adding mode. If LAN has WIFI, users can click Ў°LAN ExploreЎ± while Ў°manually inputЎ± is common used. Tick the upward side Ў°UIDЎ± and Ў°record nameЎ±. Ў°record nameЎ± can be randomly filled and Ў°UIDЎ± is from NVRЎЇs Series No.(NVR---Device---Device info). Username is admin and no password if default. If password changed, please type the right password. Channel number is determined by the actual NVR channel number, which is 1 channel in minimum and 32 channels in maxmum. After adding successfully, there is a line in the middle, if it is blue, it means device online, which can normally output image.

 

Ø How to achieve centralized management?

For simple preview, user can use standalone version network video surveillance software, which can be directly installed with compact size and manage NVR. For professional surveillance, user can user system network version CMS centralized surveillance software, which is embedded with several main module like Central Management Server, Platform Client Management Server, Storage Server and Forwarder Server, etc. It can monitor mainstream DVR, NVR and achieve the central monitor management of the different brand machines. For detail, please carefully view it on NVR CD disk.

Ø How to decode for TV wall

Via CMS central monitor software Client, user can configure decoder, which can decode NVR or ONVIF protocolЎЇs IP cameras. For detail, please carefully view it on Decode CD disk.
