Acquisition-hungry Cisco Systems today agreed to buy video surveillance vendor SyPixx Networks for $51 million in cash and stock.

SyPixx Networks makes software and hardware that converts footage from traditional analog video surveillance systems into digital form and pipes it over a computer network.

SyPixx products include analog-to-digital video camera encoders, digital-to-analog video monitor decoders, analog video transmission equipment, video recording and management software and servers.

Cisco, whose goals include providing secure voice, video and data over an IP network, will use the Waterbury, Conn. start-up's products to help customers continue using their legacy surveillance systems and integrate them into a broader physical security program.

The point is to make video accessible at any time from any place to ensure real-time response to security threats and incidents, Cisco said in a statement. SyPixx gear will help companies use new security applications and make recorded and live video more helpful.

With its Self Defending Network strategy for weeding out internal and external threats, Cisco already offers several types of security software, including firewall protection and other solutions to protect against denial-of-service attacks, worms and viruses.
