Directly Save Video Camera Feed from Linux Machine to Synology NAS via SSH

Directly Saving Video Camera Feed to a Synology NAS via SSH on a Linux Machine

In this article, we will discuss the process of directly saving a video camera feed to a Synology Network Attached Storage (NAS) via SSH on a Linux machine. This method is useful for those who want to store and access their camera feeds in a centralized location, while also ensuring the security of their data.

Prerequisites

Before we begin, make sure you have the following:

• A video camera that can output a feed via USB or other means
• A Linux machine with SSH client installed
• A Synology NAS with SSH enabled
• An Ethernet cable to connect the Linux machine and the Synology NAS

Setting up the Synology NAS

First, we need to set up the Synology NAS to accept SSH connections. To do this, follow these steps:

1. Log in to the Synology NAS web interface.
2. Navigate to the Control Panel and select the “Terminal & SNMP” option.
3. Check the “Enable SSH” box and click “Apply”.

Connecting to the Synology NAS via SSH

Next, we need to connect to the Synology NAS via SSH from the Linux machine. To do this, follow these steps:

1. Open a terminal window on the Linux machine.
2. Enter the following command to connect to the Synology NAS: ssh user@synology_nas_ip
3. Enter the password for the user when prompted.

Accessing the Camera Feed

Once connected to the Synology NAS via SSH, we can access the camera feed. The exact method for doing this will depend on the type of camera and the software it uses. However, in general, you can expect to follow these steps:

1. Connect the camera to the Linux machine via USB or other means.
2. Use a command such as lsusb to identify the camera.
3. Use a command such as ffmpeg to capture the camera feed and save it to a file on the Synology NAS. The exact command will depend on the camera and the desired format for the saved file. For example:
   ffmpeg -f video4linux2 -i /dev/video0 -c:v libx264 -preset ultrafast -b:v 500k -f mp4 /mnt/synology_nas_share/camera_feed.mp4

   This command captures video from the first video device (/dev/video0) and saves it as an MP4 file with H.264 video to a shared folder on the Synology NAS.

In this article, we have discussed the process of directly saving a video camera feed to a Synology NAS via SSH on a Linux machine. This method allows for centralized storage and access to camera feeds, while also ensuring the security of the data. By following the steps outlined in this article, you can set up your own system for saving camera feeds to a Synology NAS via SSH on a Linux machine.
