Network Impact from HD Security Cameras


Security manufacturers are developing ultra-high-resolution cameras that produce detailed images to protect facilities and monitor operations. As analog and legacy IP systems are being replaced, IT departments are being called to assist with planning, installing, and managing the HD systems.

Data and bandwidth implications

New high-resolution cameras create approximately 5 megabits of data per second (Mbps). Ultra-high megapixel panoramic cameras can create as much as 30 megabits or more of data per second. This amount of data must be managed from the moment it leaves the camera, across the network, to the viewing station at the security desk, to the storage appliance pool receiving terabytes to petabytes of streaming video 24 hours a day. Video streams must be viewed and recorded without loss of resolution.

Network infrastructure

Network switches are deployed with respect current and future demands, but often overlooking video surveillance bandwidth demands. Network administrators will need to consider the deployment of physically separated networks for security and business production. They will also consider multicast protocol to reduce network flooding in certain situations. Power over Ethernet (PoE) is the most common way to provide power to security cameras and must be considered when determining the total draw from network switch hardware.

Computer hardware

Multiple departments will need viewer access to security cameras. IT will need to determine if new cameras can be viewed reliably on the existing video graphic cards. Servers must be deployed that can handle the data being created by dozens, hundreds, or even thousands of cameras. If the organization runs in a virtualized environment, licensing and available processor assets must be assessed.

Storage appliances

The amount of storage required is computed with a formula that uses data estimations created by the cameras. Storage devices are then deployed in a centralized data center or in decentralized locations across a campus.


Reputable manufacturers engineer cameras and other devices that are penetration attack tested. They also provide regular firmware updates to ensure that new attack methods can’t exploit previously unknown vulnerabilities. Likewise, your security integration partner will perform camera firmware updates as part of the ongoing security maintenance agreement. You must also consider the increased risk of insider hacking. By placing more cameras in plain view, the risk of internal challenges to security can increase. Employees or students can attempt to access security cameras and other devices through their internal network connection. Strict password protection and, in many cases, virtual private network (VPN) policies should be used to prevent unauthorized access to security devices.
