PoE Devices

– Joe House

As the number of network connected devices continues to increase exponentially, an uninterruptible network continues to get more valuable.  Without power, you have no network – without a network you may as well have no devices!

While there are many methods a system can employ to create redundancy, the base of redundancy often relies on three letters, UPS (Uninterruptible Power Supply).  Regardless of the electrical chaos that may occur in every area around a system, the battery backup UPS maintains power to the parts of the system that need it most.  If you plan to keep a series of PoE devices alive on a UPS, Comtrol’s RocketLinx switches have two key features that can help keep your UPS running like the Energizer Bunny®.

PoE Device

Before we get started: Where are the DC Power inputs on Comtrol’s Power over Ethernet switches?  Most of Comtrol’s PoE switches support redundant DC power inputs (accepting various input voltages depending on model, but shown with +48VDC here) via screw terminal connectors as shown below.  Taking some artistic liberties, you can see how two power supplies could be wired up!


Selecting a PoE Switch: A powerful decision

PoE Switch

You just picked up some new Power over Ethernet devices – a few of the hottest new IP cameras. However, after opening the box you run into a series of unexpected problems.

PoE panel fitting First: Each camera comes equipped with its PoE injector capable of supplying the appropriate level of power.  However, prior to even mocking up your panel it becomes clear – four PoE injectors and a standard Ethernet switch will not fit!

In an effort to maintain a reasonable panel size, you ditch the PoE injectors in favor of a Power over Ethernet switch, a single product that will replace all four injectors and provide Ethernet switching.  So far so good.

Second: After deciding that a PoE switch will best suit your need, you set out on a search for the cheapest PoE switch you can find.  Before long you realize the injectors were provided so that the cameras receive the exact amount of power they are optimized to run at.  With this new concern in mind, the search moves from the “cheapest switch” to the “right switch.” In order to identify the right switch, you will need some information… but where do you look?

Monitoring power consumption of a device that is connected to a managed RocketLinx® Power over Ethernet switch

Power over Ethernet device power consumptionWinter is setting in, the days have gotten shorter, and the nights longer.  After a long cold day you find yourself lying in bed staring at the ceiling.   You start thinking about the day’s events and as you drift off somewhere between consciousness and sleep, you start to think about a project that you did this past summer where you deployed several outdoor 802.3at PoE+ cameras for a good customer of yours.  The thought of a summer project brings warm thoughts of fishing, camping and swimming… and your mind goes back to the project.  You wonder, how are those cameras holding up as each passing day gets colder and colder?

You bold upright in bed in a cold sweat.  Did I ever check to see if the cameras’ heaters came on??


License Plate Recognition System Connectivity

License Plate Recognition

As criminals are using more sophisticated tactics to implement attacks and escape punishment, security is becoming increasingly important for our law enforcement officers. Staying one step ahead of offenders requires consistent technological and intelligence innovation, and our officers continue to look for ways to keep this innovation moving forward to streamline security and law enforcement systems.

A license plate recognition (LPR) software company has introduced one such system innovation which aids officers in vehicle and criminal identification.  This License Plate Recognition software uses advanced optical character recognition to read any plate that passes in front of an integrated video camera, and instantly compares that information to crime databases for active warrants or other alerts.  If the software receives a positive hit, it alerts the officer, adds vehicle information to an internal database and instructs the camera to store the video.  The officer then has identification information for the vehicle and is able to take immediate action.  In the past, License Plate Recognition systems have required more space, cost, time and equipment than a software-only solution.  This specific software operates efficiently with any Windows PC system and IP camera(s), as long as the camera records a quality image. 

License Plate RecognitionA particular customer’s License Plate Recognition system contained specific high-power IP cameras installed in its police cars, posing a problem and potential risk.  The cars provided a significantly low initial voltage input (12VDC), which likely meant extra equipment was necessary.  The License Plate Recognition software company then discovered Comtrol’s RocketLinx® ES7106-VB (voltage boost) PoE (Power over Ethernet) switch, which used the 12VDC input power from the police cars’ cigarette lighter receptacles and converted or “boosted” output power to 48VDC – sufficient voltage to power the cameras.  Installing the switch eliminated risk of potential power inverter overheating problems, and the configuration needed no extra cabling, power supply or conversion/inversion of power between the source and the switch.  The company had previously found these extra components necessary when recommending select hardware to customers. 

Comtrol’s RocketLinx ES7106-VB switch was chosen not only for simplification, but for its durability, rugged housing and reputable name.  It is equipped with four 10/100BASE-TX PoE injector ports, with each port delivering power up to 15.4W, and two 10/100/1000BASE-TX (Gigabit) Ethernet uplink ports for transferring ddata to the network.  The switch also supports QoS, which ensures high-quality video traffic transmission by adjusting the data transfer priority.  The RocketLinx ES7106-VB is an IEEE 802.3af compliant PoE switch designed for connecting a wide range of industrial PoE equipment such as IP surveillance cameras, wireless access points and other devices utilizing 12/24V vehicle power sources or 24V standard industrial power.

This eliminates the need and expense of a separate power supply and allows direct integration with remote and vehicle power systems.

Forced power mode
RocketLinx PoE switches provide advanced forced powering control, bringing power to non-standard and older PoE devices that cannot be detected as valid PDs.

PoE port scheduling
Comtrol’s PoE port scheduling feature provides an hourly/weekly scheduling mechanism for advanced power control.  Each PoE port can be configured to be ON or OFF on an hourly basis to conserve energy and guarantee power only when needed.

Smart power device link connect
Monitor the status of PDs connected to RocketLinx PoE switches through RocketLinx PD management technology.  When a PD fails to respond, the PoE port can cycle power, thereby resetting the PD and restoring functionality.

Power budget limitation with priority control
When conditions demand power exceeding the power budget threshold, the RocketLinx PoE switches provide budget and priority control ensuring that the total power consumption will not exceed the power limit defined by the user. It also allows the user to protect the high-priority PDs by limiting the output power, prioritizing port shut down, and maintaining power to the highest priority devices.

*The RocketLinx ES7506 and ES7528 have numbered port-based priority control, while the ES7510-XT and ES7528 feature two-level port-based priority control
