The purposes of IR repeater systems are simple: to effectively relay the Infrared signals from one place to a remote location to execute commands. In simpler terms, it is simply a very handy way where one can use a remote control for changing audio/video instruction in devices which are located in an entirely different room or locations. This is done via relaying the signals from the infrared signaling devices (for example. a remote control) and relay the signals via various IR repeaters located at precise positions and finally executing the intended commands at the devices located in a different location. IR Repeater systems may be used for both commercial and residential purposes, while especially popular with home designs intended to conceal the clunky audio video equipment for interior designs. IR repeater systems are also widely used in studios or the movie industry where equipment and control locations are usually separate.
Infra-Red repeater systems come across various pricing and options, and can easily range from $100 up to $250. Since these IR Repeater systems are usually a permanent fixture of a house, and any repairs or replacement would normally result in changing multiple wiring and repeaters in multiple locations, experts often recommend getting a unit which is renowned for sustainable performance over longer stretches of time. IR Repeater systems used for the automation of a house, for example – remotely controlled operation of window drapes, lighting, gates etc. from a central command usually require the implementation of a custom made IR Repeater system, and can range up to $5000 depending on the vendor. However, the science behind IR Repeater systems is not very complex, and often the owners can install the system themselves.
The IR repeater systems generally come in a package containing a low capacitance cable of up to 20 meters, up to 4 or more repeaters or emitters, an infrared connecting block and a IR 250 or IR 350 infrared receiver unit and a power adapter unit. Before installing the system, it is imperative that the owners test the units and make sure that there are no unwanted interferences in the surrounding environment which might cause a disruption in the proper functioning of the system.
Since IR Repeater systems need a substantial amount of re-structuring and positioning of cables, repeaters, adapter switches – discovering a disruptive interference after the unit has been installed can prove to be expensive and frustrating. The simple test can be carried out where the users place an emitter in front of the audio/video or any other remotely operable IR receiver unit, and simply drag down the cable and place the repeaters on the floor or over the furniture without permanently installing them, and test it from the desired location.
For installing the unit, a set of wire strippers or diagonal cutters, a few star headed screw drivers and a pocket knife to scour the insulation of the cable is required. Installing the unit is very straightforward. First, one end of the cable should be scoured off the PVC insulation with the help of the pocket knife, and the internal conducting cables should be stripped off with the copper wires exposed. They are then inserted into the IR Receiver unit, according to the specifications provided in the user’s manual, which follows a strict pattern according to colour codes. Now the other end of the cable should be stripped off as mentioned before and inserted to the IR connecting block. There is a signal LED which should illuminate only when a remote IR device is directed to it, and if it blinks continuously – it is usually the signs of interference. The IR emitters are then strategically placed; with the final one glued next the receiver equipment.
