Numerous manufacturers, such as Nitek, NVT, and Veracity (probably the most popular) provide units which allow Ethernet and power to travel over a single RG-59 coax cable. The third, and probably least thought-of option, is Ethernet over coax. PoE extenders can be found online for about $150-200. So, we would expect that allowances may be made in the future for units such as these, as long as each of the individual cable segments are terminated and tested.
#POE IP CAMERA MOD#
Some leeway has been given for direct connection of cameras, recently that is, terminating the camera end of the cable with a mod plug instead of a jack and patch cord. Inserting PoE extenders between 2000' of cable obviously does not meet these standards. The BICSI TDMM calls for all ethernet cables to be terminated to a patch panel at one end, and a jack at the other. One potential drawback, which may be of concern to some users, is whether cabling topology for these units is standards-compliant.
#POE IP CAMERA INSTALL#
PoE extenders are intended to be simple to install and plug-and-play, requiring no configuration, but simply plugging in cables in either side. Both interior and exterior versions of some of these devices are available, to fit different installation environments. These units are installed in-line in a run of UTP cable, and boost the distance at which PoE can be supplied, up to a maximum of 1,500-2,000 feet with some units. PoE extenders such as Veracity's OUTREACH or Nitek's EE328 are the second option.
It also is the only option which adheres to all cabling standards, making it attractive for some users with those concerns.
Though it is expensive, OneReach does support PoE at distances far greater than other options, with a maximum distance of 3,850', meaning it may be an option where PoE extenders or ethernet over coax is not. The cost for the runner cable will vary widely, depending on length, termination types, copper wire gauge, and fiber type. PoE injectors and remote units can be found for $689 online, with one required on either end. The OneReach system does add some cost compared to standard fiber cable or the other options examined herein. It also eliminates the need for specialized skills to terminate the fiber cable, since the runners ship pre-terminated. This setup eliminates the need for high-voltage power at the far end of the run, potentially providing savings when compared to having AC power installed in these locations. The powered endpoint supplies one or more PoE ports, drawing power from the copper in the runner cable, and data via the fiber. OneReach consists of a power injector, a hybrid fiber/copper runner cable, and a breakout box with PoE port at the far end. One recently released product, Berk-Tek's OneReach system, is aiming to eliminate the need to install high voltage at the device location. If local power was not already existing, electricians were needed to install it, making the addition of a device in this location more costly. Typically, this required the far end device to have local power installed. One common option for connecting a camera or other device in a remote location on site was to run fiber directly to the camera from the head end. For those occassions, this note helps you choose between Fiber, PoE extenders and Ethernet over Coax (EoC) However, there are times when an IP camera is simply hundreds or thousands of meters away with nothing in between. This is a controversial criticism for sure as IP has the powerful advantage of networking across large IP networks that can easily overcome even great distances. A common question in IP surveillance is: What are the best ways to extend power and Ethernet past the typical 100 Meter limitation of UTP cable? Indeed, this is often cited as a weakness of IP relative to analog cameras.
