Small-Sized Video Surveillance Network

In a Point of Sale (POS) and security camera installation with a limited number of cameras, a single or small group of Allied Telesis WebSmart Power over Ethernet (PoE) switches is an ideal solution because of its simplified network configuration and maintenance requirements.

Example Scenario

The retail store is a single unit within a strip mall. To prevent shoplifting and employee theft/fraud, the owner installs a surveillance system. This improves employee and customer safety, and deters shoplifting. This type of project requires multiple cameras due to the layout of the store. Most of the cameras are installed inside the store, with a few cameras installed outside to monitor the front and rear entrance. The physical layout of this site is small, so all of the cameras are connected to a single switch.

The security network uses existing Internet connectivity, but must be kept separate from the POS system installed in the store — a requirement of the POS vendor that provides support for that system.


The Allied Telesis GS950 PS Series of high performance, eco-friendly Gigabit WebSmart switches provides simple yet secure management features at an affordable level, improving the delivery of converged data. The AT-GS950/16PS provides standards-based IEEE 802.3af PoE to all 12 10/100/1000T ports at 15.4W. It also supports IEEE 802.3at PoE+ for up to six ports at 30W. For high-definition cameras, automatic doors and VoIP phones, the GS950 Series supports double the amount of MAC addresses supported by competitive products — double the number of devices may be connected to the network, ensuring that infrastructure installed today will support future needs. Security protocols such as 802.1x, RADIUS and port MAC address security administration facilitate the protection of the network for both local and remote connections.
