Churches are always on a budget, but there is a right and a wrong way in purchasing gear. I have seen many installation companies screw this one up. Demo gear before purchasing, yes, they let you do that!
Churches are live IMAG environments and most people forget that little concept. This is huge because IMAG requires no-delay. Most, not all, cheap gear out there has lots of delay and once the signal hits the screens it looks like a bad Chinese movie. Gear to watch for includes: Projectors, switchers, Cameras, Distribution amps, scalars, scan converters, and routers. Just because it says professional on it doesn’t mean it doesn’t have delay.
Demo the gear before buying; ask the question on how much delay a piece of gear has. 2-3 frames or 66-99 milliseconds is the most I would recommend before the delay gets noticeable.
Delay is the number one most important aspect to work through when designing an IMAG system and yet it is the one that is most commonly missed. Either spend the extra money on the right gear, or re-evaluate if you should do IMAG. If you must do IMAG I would definitely look at putting in used gear if you can’t afford new. You will save lots of money and be able to get the gear necessary to have a low cost, low delay system with high quality.
