There’s a tremendous amount of confusion over choosing the right switch for video surveillance – Commercial Grade, Industrial Grade, Hardened Switches.  Below is an excerpt taken from a new report that Wave Representatives will be releasing after ISC West to help security professionals recommend purpose built, physical security switches on their video surveillance applications.

  • Hardened & Industrial.  Utility switches provide robust operating conditions.  Industrial switches can range from -14° ~ +131°F and hardened ruggedized units operating temperatures can withstand -40° ~ +167°F.  Heat is a major factor in hardware failure, industrial switches provide a level of functionality that Information Technology focused switch manufacturers do not.Let’s take an analogy of a Ferrari versus an Jeep, both get you from point A to point B but do what they do better than the other.  Cisco switches are the Ferrari, fast, feature rich, but requires a fixed environment to perform as expected.  Utility switches are like the Jeep, they can endure abuse, focus on utility and durability and provide confidence in its ability to perform within elevated, rough terrain.
  • Dedicated Security Network.  The ideal camera network does not interact with the customer’s network (including VLANS).  This provides an added layer of security, but also provides the bandwidth and IP addressing needed by Systems Integrators and ensures serviceability of the system.
  • Power – Power over Ethernet: a system that allows electrical power and the data to be transmitted along the same Ethernet cable. In our product descriptions, we refer to PoE and PoE+, PoE refers to the IEEE802.3af standard and PoE+ refers to the higher power, IEEE802.3at standard.  Our transmission solutions are built to provide maximum power options, most switches require security installers to power budget, meaning they only provide PoE to some of the ports not all.  The Industrial 24-port switch we carry provides 30W (PoE+) at every port, 24×30 = 720W power budget.  This is ideal for camera installations where the installation team doesn’t need to worry about running out of usable ports.
  • Non-blocking, is key in delivering uninterrupted camera traffic. For example, the same 24 port gigabit switch referenced above, with each port running at 2Gbps (full duplex), means that those 24 ports have a presumed maximum speed of 48Gbps. When data (camera traffic) is passed uninterrupted, the switch performance is considered non-blocking.

When considering switches – purchasing a purpose-built utility switch avoids troubleshooting; dropped cameras, video jitter from lag, dropped frame issues, overheating failures and involving end users with debugging their network issues.  It provides a clear demarcation line between your solution and their network.  While utility switches may cost more – they pay for themselves many times over with faster installations and higher performance.
