Cameras
You can add your cameras to U-alarm and watch their live play here.

Before starting
Please make sure that everything described in the First Steps is done and you have all these information for each camera:
The location / desired name of the camera
Camera RTSP address (including username and password if the camera is protected)
The current resolution and FPS setting.
Number of supported cameras
U-alarm handles multiple cameras. In the bottom-left corner the CPU / GPU / Memory load is indicated. Please consider limiting the number of registered cameras if any of these values are too high.
Example
Use case | Hardware | Number of cameras | Resolution | FPS |
---|---|---|---|---|
Intrusion detection | NX | 10 | 1280 x 720 | 2 |
Intrusion detection | NX | 5 | 1280 x 720 | 4 |
Intrusion detection | NX | 2 | 1920 x 1080 | 8 |
Intrusion detection (PTZ) | NX | 4 | 640 x 480 | 2 |
Crowd detection | NX | 10 | 1920 x 1080 | 4 |
Intrusion detection | TX2 | 4 | 1280 x 720 | 2 |
Intrusion detection | TX2 | 2 | 1280 x 720 | 4 |
Intrusion detection | TX2 | 1 | 1920 x 1080 | 8 |
Intrusion detection (PTZ) | TX2 | 1 | 640 x 480 | 2 |
Crowd detection | TX2 | 4 | 1920 x 1080 | 4 |
