Things to consider when rolling out a video-based network
surveillance setup
It’s great to be able to add surveillance to your existing Ethernet-based data network but to ensure you continue to get
the best performance from your network, below you will find some useful tips.
1. Your normal data trac overwhelming your surveillance trac
• If a large amount of data is being transferred in your network, your surveillance traffic can experience congestion
which can lead to poor video quality or even lost footage.
• This can be addressed by segregating data traffic from surveillance traffic.
• Auto- Surveillance VLAN - D-Link provides a feature called Auto-Surveillance VLAN which automatically prioritises
Surveillance traffic to ensure uninterrupted and secure connection between your network cameras and storage or
monitoring devices. It enables you to safely and securely transmit the captured images/video by:
• Automatically creating a VLAN that separates surveillance traffic and sets Quality of Service (QoS) to high priority.
• Handling both data and surveillance traffic, saving you the costs of deploying and maintaining a separate network
for surveillance traffic only
• Securing surveillance traffic and ensuring smooth video streaming even during periods of heavy data traffic
