Hardware Problems

1.1 Doing Waterproof to Cable Joints
Make sure to do waterproof to all the cable joints with insulating tape and waterproof tape to avoid short circuit and water damage.
The following figures are for reference only, and the actual product shall prevail.
Step 1 Connect cables. Step 2 Do insulation for the connected cables with insulating tape. Step 3 Cover all the exposed parts with insulating tape. Step 4 Select the starting point for taping the waterproof tape. Step 5 Do waterproof to all the exposed parts. 1.2 PoE Power Supply
1.2.1 Power Supply Mode
The cameras with PoE power supply mode comply with 802.3af or 802.3at protocol, and the max. output power is 13W (802.3af) or 25W (802.3at).
1.2.2 PoE Mode
The cameras with PoE power supply support data cable power supply and idle cable power supply.

Model A (data cable 12, 36 power supply, and electrodes can be crossed: 36 (green and white, green) is positive electrode (+); 12 (orange and white, orange) is negative electrode (–) or 36 (green and white, green) is negative electrode (–); 12 (orange and white, orange) is positive electrode (+).
Model B (idle cable 45, 78 power supply, and electrodes cannot be crossed: 45 (blue, blue and white) is positive electrode (+); 78 (brown and white, brown) is negative electrode (–).

Network Problems

2.1 IPC goes offline and online from time to time
Solutions:

Check whether the network connection is stable or whether the network cable is loose.
Check whether there is IP conflict.
Check whether the camera is under proper power supply.
Check whether the camera has been upgraded with a wrong program.

2.2 Online upgrade failed
Solutions:

Log in again to check whether the upgrade is successful, because sometimes the progress bar is not displayed in time due to the network environment.
Check whether the network connection is stable, and whether there is disconnection or power failure during upgrade.
Check whether the program matches to the camera.
Upgrade again through ConfigTool.
OEM camera can upgrade with OEM program only.
You cannot upgrade the program to an earlier version, because the later version provides better service.

2.3 After upgrading, the camera IP can be pinged, but login failed
Solutions:

Wait for several minutes (less than 5 minutes), and then log in again.
Check whether HTTP port is modified, and the default value is 80. If yes, add the modified value after IP address when logging in through browser.
If you still cannot log in to the camera after long time waiting, reset the camera and log in again.

2.4 After upgrading, the camera IP cannot be pinged
Solutions:

Ping other devices in the network to check whether the network connection is working.
Check whether the parameters of IP address, default gateway and subnet mask are configured correctly. If the IP is not obtained through DHCP, check whether the camera IP and router gateway are in the same network segment.
Press the reset button to reset the camera, and the IP is 192.168.1.108 by default.

2.5 No video after upgrading
Solutions:

Check whether there is IP conflict or network disconnection.
Delete the control and install it again (path: C:\Program Files\webrec), and clear the buffer of the browser.
Disable the PC firewall, and add the camera IP as the trusted site on the setting interface of the browser.
If the OS is Windows 7, run IE as administrator.
If the browser is Edge, Chrome (later than 42), or Firefox (later than 52), you are recommended to use IE.

2.6 “Limited Resources, Failed to Enable Video” is Displayed
Solutions:

Network bandwidth is not enough; use a switcher with bigger bandwidth.
Check whether too many users have logged in, and the stream output capacity is not enough.
The network connection is not stable. For solutions, see “2.1 IPC goes offline and online from time to time.”
Delete the control and install it again (path: C:\Program Files\webrec), and clear the buffer of the browser.
Log in to the web, and then restore the camera to default configuration.

2.7 Video window requires control, but “ ” is displayed
Solutions:

Check whether the IE permission setting is correct, and add the camera IP as a trusted site.
In IE browser, select Internet Options > Security > Custom Level > Active X Control and Plug-in, and then select Enable for all the plug-ins.
Delete the control and install it again (path: C:\Program Files\webrec), and clear the buffer of the browser.

2.8 When you setting the port, the system prompts that the port is occupied
Solution:
Check whether the system sets limit to the port to avoid other configuration occupying the used port. For details, see Web Operation Manual.

Image Problems

3.1 IR imaging is not good
Solutions:

Check whether the specified power supply is used. If you do not use the specified power supply, some IR lights might not be on.
The target is too far, and it is out of the range of the IR lights. Adjust the installation position of the camera.
Check whether Day/Night mode is set as color mode, and the sensor is failed to receive IR light. Log in to the web, and then set Day/Night mode to W/B or auto mode.
When the camera is placed near a reflector (such as table and wall), the IR light that goes to the reflector will be reflected back to the lens, which will cause pale image. Adjust the lens to elevation angle or place the camera at the edge of the reflector.
For dome camera, you can clear the lens and protective enclosure, and install the protective enclosure.

3.2 Failed to record video or take snapshot
Solutions:

Configure Record Schedule and Snapshot Schedule on the web interface. For details, see Web Operation Manual.
Check whether the Destination is enabled on the web interface.
Check whether the storage (such as SD card or FTP server) is configured properly, and you can test the FTP server connection with your PC.
Set Record Mode to Manual or Auto on the web interface.

3.3 Black border appears in the image
Solutions:

For box camera, incorrect model selection of lens will cause the black border in the image.
For the camera with FPGA program, upgrade the FPGA program when upgrading the camera.

3.4 Stripes appear in the image
Solutions:

Check whether the connection for the video cable is OK.
Check whether there is strong current interference.
It could be flicker. Log in to the web, and set the shutter parameters. The parameters should be set to be an integer multiple of the half flicker cycle (If the flicker cycle is 50 Hz, set the shutter to be an integer multiple of 10 ms; if the flicker cycle is 50 Hz, set the shutter to be an integer multiple of 8.33 ms).

3.5 Image disappears sometimes
Solutions:

Check whether the connection for the video cable is OK.
The network is not stable. For details, see “2.1 IPC goes offline and online from time to time.”

3.6 For box camera, the image might blur after running for a period
Solutions:

Check whether the focus locking ring is loosening.
Check whether the CS adapter ring is loosening.
Check whether the fixing screw of the rear focus ring CS adapter ring is loosening.

3.7 Fail to switch B/W mode to color mode
Solutions:

Check the scene brightness, and check whether the photoresist is covered. If yes, move the cover, or adjust the camera angle to a proper position.
Select Auto for Day & Night, and adjust sensitivity.
▷ Low sensitivity: The camera is less sensitive to the light changing.
▷ High sensitivity: The camera is more sensitive to the light changing.
