Unlike old analog cameras, a network camera acts as a smart, standalone device. It has its own IP address, a built-in computer chip, and a web server. It turns video into digital data and sends it over Wi-Fi or an Ethernet cable. [1, 2, 3, 4, 5]

[All cameras] How to troubleshoot when the camera’s web UI is not functioning properly?

Question

How to troubleshoot when the camera’s web UI is abnormal?

Below are two snapshots of the abnormal web UI.

Answer

This problem commonly arises after a camera firmware update or if the camera’s IP address was previously assigned to a different camera. The browser’s cache persists with outdated webpage data from the camera’s pre-update state or from the prior camera, which leads to the camera’s webpage failing to display properly.

[All Cameras] How can I check if the camera IP is used by another device?

Question

How can I check if the camera IP is used by another device?

Answer

IP conflicts occur when two devices on the same network are assigned the same IP address. This can lead to connectivity issues, and it’s essential to resolve such conflicts to ensure smooth network operation. If you suspect your camera’s IP address might be used by another device, here’s how you can check and resolve it.

1. Disconnect the camera from the network.

2. Connect a PC to the same network as the camera. Then, open the Windows Command Prompt (cmd.exe).

3. Execute the ping command followed by the camera’s IP address:

ping <Camera IP>

If you are unable to locate the device or computer using the originally designated IP, consider setting a new IP address for the camera to avoid IP conflicts.

[All cameras] How to use PowerShell to test if the camera IP and ports can be accessed?

Question

How to use PowerShell to test if the camera IP and ports can be accessed?

Answer

There are several ways to test if your camera IP can be reached, one of the most used is the “ping” command:

Unfortunately, the ping command has its limitations and wont be able to verify if the ports of the pinged IP are open (ping commands are sent using random ports). In order to check the port connectivity you can use the “Test-NetConnection” command in power shell which can test connectivity to a specific IP and port. To do so please follow the next steps:

Step 1. Open the Windows PowerShell, you can do it by typing “PoweSheel” in the start menu search:

Step 2. Type the following command:

Test-NetConnection -ComputerName [IP address] -Port [port number]

Where the [IP address] is the camera IP and the [port number] is the port that you are trying to verify.

Step 3. Press enter to run the command and the following will appear:

The process will take a couple of seconds and once finished it will display the connection status as follows:

If the connection cannot be stablished, the following error will appear:

Note: the same process can be used to check ND/VAST2/VSS connectivity (all of those devices/software uses different ports to communicate).

If there is a connection error you can do the following to ensure that the camera port can be accessed:

If after checking the points mentioned above you are still unable to access the camera using its IP and port please contact Technical Support for assistance.

Before sending following URL to the camera, please ensure that the CSRF feature is disabled.

If you need guidance on how to disable the CSRF feature, please refer to the following link: [All cameras] What to do when you cannot send CGI command to the camera after upgrade the camera firmware to the latest? – VIVOTEK Support Center
The URL command as below:

http://{Camera_IP_address}/cgi-bin/viewer/video.jpg

For Mutiple sensor camera, please use the below URL command to check camera streaming.

http://{Camera_IP_address}//cgi-bin/viewer/video.jpg?channel=0&streamId=0&qulity=quality

Channel 0=first lens.

If there is no image displayed, this will mean that the video sensor might be compromised.

4. Use and RTSP Player to verify if the camera can send data through RTSP
