Question: I need to access the camera from the outside, I have forwarded port 80. I can go to the web interface of the camera, but the video does not go. When I log in from the local network, there is a video. What other ports need to be forwarded?
Answer: For Internet Explorer — HTTP port (80), RTSP port (554), TCP port (6000).
For Google Chrome, Mozilla Firefox and other browsers — HTTP port (80), RTSP port (554), FLASH port (1935).
The port values are specified by default. All ports, except HTTP, must be forwarded symmetrically.
Only for camera models:

Connecting cameras to the TRASSIR software from a remote network
Adding cameras to the TRASSIR software when the cameras are behind the NAT (remote camera with port forwarding).
The question often arises: how to add one or more cameras to the TRASSIR software from a remote object with port forwarding and which ports need to be forwarded for this?
In this article we will try to analyze this issue.
Which ports should I forward?
Usually, two ports are required for the full operation of a video surveillance camera in the TRASSIR software:
- Control port
- Video port (RTSP)
The control port can be different. For example, some Hikvision cameras work via the SDK - 8000 port, and modern Hikvision\Hiwatch cameras are connected via the ISAPI - 80 port.
If the camera is not integrated into the TRASSIR software, then most likely it can be connected via the ONVIF protocol. The port for connecting via the ONVIF protocol is also not always standard and may differ from 80.
How do I find out which control port is on the camera?
The easiest way is to create a manual connection with this camera in the TRASSIR software and see which port the connection is made on:
If the camera is connected via the ONVIF protocol, then the port can be determined using the Onvif Device Manager program.
To do this, log in with the data from the camera (Login). In the string “identification” in the substring “URI” you will see the port.
For example 192.181.123.3:2000, where 2000 is the port. If there is no colon, then the port is 80.
When you have decided on the port, you can not forward it symmetrically, that is, the external port may differ from the internal real port of the camera.
Example: 81 external ports, and 80 internal. If necessary, you can change the control port on the camera and perform symmetrical port forwarding, thereby simplifying system maintenance.
Video Port (RTSP)
By default, this port is set to 554 for most cameras. It always needs to be routed symmetrically, that is, the internal and external ports must match.
This is due to the fact that the TRASSIR software requests information from the camera about its RTSP port and generates a video request link based on the data received.
If there are two or more cameras on the network, then in this case we recommend changing the RTSP port on the camera's web interface and already passing it symmetrically, for example, replacing the first or last character in ascending order.
Example:
| External port | Internal port |
|---|---|
| 554 | 554 |
| 555 | 555 |
| 556 | 556 |
| 557 | 557 |
When adding a camera to the TRASSIR software via the RTSP protocol, it is not necessary to forward the ports symmetrically, since the link explicitly indicates which port to pick up the video stream from.
