Knight Security Provides Comprehensive Network-based Video Surveillance System for the State of Texas, USA
“ZyXEL provided the comprehensive, scalable network infrastructure required for this project and they backed it with outstanding support and training to insure that we had a successful deployment. They’ve been a great partner.”

The State of Texas Department of Aging and Disability Services (DADS) was created to administer long-term services and support for people who are aging and who have cognitive and physical disabilities. DADS also licenses and regulates providers of these services, and administers the State’s guardianship program. DADS needed a method to insure proper care and safety to its residents and clients, and determined that a video surveillance solution would be the answer.
The system requirements included a turnkey video and surveillance and monitoring solution for 12 state-supported living centers spread across the State of Texas. Each living center campus was different; some had only six buildings and some had 62 buildings, but all required video surveillance. Another consideration was network monitoring & management. With several thousand cameras in the field and multiple network switches providing backhaul, it was important that the entire network is easily monitored and managed from a central location.
Solutions and Benefits
DADS selected Knight Security Systems because of their expertise in video surveillance and system design. The Knight Security solution provided a common platform across all systems while assuring seamless control by way of SNMP network monitoring and management. Knight Security chose ZyXEL because ZyXEL offered the proper mix of switches to meet all requirements of the DADS contract. The need for a small PoE switch with fibre backhaul to a high capacity core switch was of extreme importance. ZyXEL provided a comprehensive networking solution that precluded the need to bring in networking products from other vendors. ZyXEL’s USG series of UTM (Unified Threat Management) security appliances was chosen to act as the gateway to the IP backbone and provide a secure IPSec VPN tunnel from each campus back to Knight Security’s Customer Support Center.
ZyXEL’s XGS series of switches was used to aggregate fibre links between the buildings and provide routing functionality. The high capacity switches met the demands of always-on streaming video. ZyXEL’s GS2200 series of switches provided Ethernet connectivity from the XGS switch to video (and other) servers located on each campus. ZyXEL’s ES series of PoE products was used to provide PoE power to the cameras. The cameras required only three watts of power from each port.
ZyXEL’s “consumption mode” allowed Knight Security to use affordable “half power” switches and still provide sufficient power at each port to power all cameras. The ability to prioritize ports also ensured that, should a high-consumption device be connected, critical devices would still operate without interruption.
ZyXEL’s ProEMS network monitoring & management solution was also used to provide network monitoring for all network devices at each campus. ProEMS provides an easy to use interface for monitoring and managing all switches, UPS systems, servers and cameras deployed in the field.
ZyXEL’s wide range of products allowed Knight Security to source all the switches needed for the deployment from one vendor. All equipment, from small PoE switches to layer 3+ switches with 10G backhaul were all offered by ZyXEL. The total cost of the ZyXEL-based solution is significantly lower than competitors’ solutions.
ZyXEL’s limited lifetime switch warranty and 5-year firewall warranty are also two important factors for Knight Security to choose ZyXEL products. The unique feature set of the ES-2108PWR (8 port full power PoE switch wtih Gigabit fiber backhaul, please refer to ES3500 Series for the replacement) further convinced Knight Security of the end-to-end solution from ZyXEL.
