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.

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 1
st
channel and next
second in 3
rd
channel, then next second has no idea in which channel.
4. 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.
5. 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.
6. 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 “Start” to choose current login user as “Administrator”, tick Control
Panel---User Accounts and Family Safety---Change User Account Control Setting, then lower
down to “Never notify”. Open IE browser and press “Tools” to see “Internet
Options”---“Security”---“Custom Level”, adjust ActiveX controls and plugins to “Enable” or
“Prompt” and “Disable” “Binary and script behaviors” alone. Follow the same setting step in
“Local Intranet” and tick “OK”, restart IE browser. Finally press “Alt” to see “Tools” and tick
“Compability View Setting” to check “Display all websites in Compability View” . Click “OK”
and reopen IE browser.
3) Check whether PC had installed ActiveX in previous time. Close IE browser and go to
“Program Files[WinXP]” folder in C Disk, then delete “dvr_activex” whole folder, while deleting
“dvr_activex” folder in “Program Files(x86)[Win7&8]”, 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 “login” and click right mouse to see “Open All” or tick the × to √ in
every screen right corner.
