The below guide will show the step-by-step process of enabling Multicasting on a Wisenet camera, enabling a network switch, testing the multicast stream using VLC & adding the Multicast stream on a SPD-151 Decoder.

Note - This guide assumes your cameras and display devices (SPD-151 for example) are on the same VLAN.

Enabling Multicasting on a Wisenet camera. 

• Choose the video profile you want to enable Multicasting on.

• Scroll down to the Multicast section, in this guide I have given the camera an address of 224.3.2.1 - This can be anything between 224.0.0.0 and 239.255.255.255.
• Enter a port number, here I have used 1024, this can be anywhere from 1024 up to 65534. (port 3702 cannot be used) 
• TTL is how many router hops the Multicast traffic is allowed to pass through, the default value is 5.
• Click Apply once finished.

Enabling Multicast On The Network Switches.

In this example we are using a Layer 2 switch, IGMP Snooping must be enabled for the multicast traffic to travel properly through the network.

Note - IGMP Snooping must be enabled on ALL network switches between the Cameras and the display devices.

Using the Unifi portal from Ubiquiti, we can enable IGMP Snooping under Networks.

• Select the network with your CCTV traffic - Default network used here. 

• Tick Enable for IGMP Snooping and click Apply Changes.

• Note - Using a Netgear managed switch, the process is similar.

Loading A Multicast Stream In VLC.

In this example, the camera used has an IP address of 192.168.20.241, we have enabled Multicasting on Video Profile 2 - this is the RTSP stream we will use.

rtsp://192.168.20.241:554/multicast/profile2/media.smp

• Open VLC and select Open Network Stream.

• Enter the RTSP URL and click Play.

• Enter the camera's Username and Password.

The Multicast video stream should now be shown.

Displaying a Multicast RTSP stream on a SPD-151 decoder.

• Navigate to the decoder webpage and click + to add a camera.
• Click Manual.
• Choose RTSP Protocol
• Enter the camera RTSP URL (Example - rtsp://192.168.20.241:554/multicast/profile2/media.smp)
• Enter the camera username and password.
• Click More Details and select UDP Mode (important step)
• Click OK
• Drag the newly added camera into the video tile of your choice.
