| IP Camera FAQ
|
| Problem
|
Solution
|
| My IP Camera is off line from time to time
|
| Check if the network environment is good and the network cable hole plug of IPC end is loose.
|
| Check if there is IP conflict.
|
| Check if the device is under normal power supply.
|
| Check if the device upgraded to a wrong program.
|
| My IP Camera is off line from time to time
|
| Log in again to check if upgrade is successful, because sometimes the progress bar doesn’t show feedback in time due to the network environment.
|
| Check if the network environment is normal, and there is disconnection or power failure during upgrade.
|
| Check if the program and the device are matched.
|
| I can use “Ping” to test that the IPC is on line after upgrade, but fail to log in.
|
| Check if the WEB port was modified.
|
| Reset the device and log in again.
|
| There is no code stream when I log in and the network program restarts constantly after upgrade.
|
| Check if there is IP conflict or network disconnection.
|
| Check if the device is under normal power supply.
|
| Check if each connection line is loose inside the device after disassembling the camera.
|
| Check if the application program of IPC is corresponding to the model, and check if N/P format program is correct.
|
| Check if the control and WEB are correct, there is control running permission under WIN7, you can delete the control under C:\Program Files\webrec and eliminate IE buffer memory to reload control and WEB. Please run IE as administrator for WIN 7, you need to install QuickTime plug-in if it is non-IE browser.
|
| It displays “Resources are limited, failed to open video” after I log in the IPC.
|
| Network bandwidth is not enough; change a switcher with bigger bandwidth.
|
| Too many users logging in, and it is beyond the device code stream output capacity.
|
| Disconnect the network or restart the device repeatedly, see 1.1 for more details.
|
| IR effect is bad.
|
| Users didn’t use specified power supply, and failed to enable all the IR lights.
|
| The object is so far that it is out of the range of IR light.
|
| IR-CUT is set as color mode, which caused the front-end sensor to fail to sense IR light.
|
| When you use the device on the table (especially rough surface), the IR light will shoot back to the lens, which will cause bad IR effect and white picture. At this moment, you should adjust the elevation angle of the lens or place the device on the edge
|
| The device failed to record video and snapshot.
|
| “Snapshot time period” is set wrongly; storage path is not correct; “video mode” is set as off.
|
| Set “video time period”, “snapshot time period” in the WEB interface; please refer to the <IPC WEB Operation Manual> for more details.
|
| Check if the “memory point” enable in the WEB interface is checked.
|
| Check if the connection of SD and FTP of video and snapshot storage is normal, try to connect FTP to the computer.
|
| Set “video mode” as manual or auto in the WEB interface.
|
| Black edge appears in the image after upgrade.
|
| Eliminate IPC configuration or restore factory default after upgrading program.
|

|
| Gray screen appears in the IPC.
|
| Gray screen appears in the IPC, it can recover after restart under the state of power off, gray screen appears repeatedly.
|
| Caused by insufficient power supply.
|
| Check if the IPC power supply mode and power adapter are too far away from the IPC.
|
| Gray screen appears in the IPC.
|
| Use the IR-blocking ring of the lens, or reinstall the light-blocking ring to a proper position
|
| I forgot the Device IP.
|
| Find the device IP by quick configuration tool.
|
| If you know the device MAC address, you can set device IP address by modifying ARP/Ping command. Please refer to <WEB Operation Manual> for more details.
|
| If you are Apple user, you can search the Bonjour server name of IPC and log in IPC by the browser with Bonjour service.
|
| I failed to log in WEB.
|
| User name and password are not correct, network and power adapter problems.
|
| Please enter correct user name and password.
|
| Check if the network cable is normal and usable, and check if the network configuration is correct or pull out the network cable plug in again.
|
| Please connect default power adapter
|
| I failed to play the downloaded audio and video files.
|
| Player problem.
|
| Please download the company default player from the disc.
|
| Install graphics acceleration software whose version is higher than DX8.1
|
| Use MEDIA PLAYER to play the file which is converted to AVI format, install Div X503Bundle.exe plug-in.
|
| Winxp operating system needs to install plug-in DivX503Bundle.exe and ffdsho-20041012.exe.
|
| Day/night config switch is invalid.

| Check if the SD card in the computer is recognizable and there is no abnormality.
|
| Config info is mismatched with real situation after IPC working for a while.
|
| Refresh the interface.
|
| It is caused due to the modification of IPC config; it doesn’t belong to the IPC problem. Users can check what platform manages IPC or which device that the rear end is connected to. They can use check the exact reason by adopting separated checking method. Currently the PSS client and soft decoder can modify the Baud rate of some IPC, which leads to a situation where the IPC is out of control.
|
| Power adapter is unsteady.
|
| The high and low temperature environment is from 0℃ to 40℃ for general power adapters, the power supply will become unsteady if the adapter is beyond this range. Therefore, it is necessary to change to industrial power adapter

|
| Check if the SD card status is set as read only status, if so; you need to change it to read/write status.
|
| Check if the SD card can be detected.
|
| Check if the SD card has been damaged.
|
| Check if the SD card is full, if it shows that the residual space is 0, you can format the SD card by WEB interface or check “Cover” in the “Storage management > Video control > hard disk full” of the WEB interface.
