Thread: Live Projection of photos, market rate

  1. #1

    Default Live Projection of photos, market rate

    Thanks to sjackel and Hart, answers found. Market rate is $400-500.

    What i found out is that it is not easy to do anyway and not worth it to do at a low price. Its pretty stressful when you are setting up and run into issues - once I found that the patch VGA cable is not up to par, once I was troubleshooting for 15 mins due to this and unable to take photos.

    My experience is that if you are committed to provide a service, say Express Highlights or Live Projection or whatever, it is not as simple as saying "oh, something went wrong, can we just do away with it and I'll deduct 100% that component? I mean we are talking about LIVE here, or Express.". We'd love it to work this way, but in reality sometimes it doesn't esp if you are in a higher price bracket.

    I've yet to do Raffles City Padang or Suntec, where there would be a huge group of people blocking. (specifically 2.4GHz freq is very nicely blocked by water, ie human bodies. That's how your microwave oven works).

    I have purchased this 10dBi ($22) antenna for my USB adapter to try first, sheesh it is about 2-5dBm down compared to the 7dB Aztech antenna when I am reading the specialised wireless utilily.

    They have some pretty cool products like high powered (1001mW RF, not sure how it passes through IDA) USB adapter with 9dBi omni antenna costing $40 only, high powered AP with directional 15dBi antenna etc. (about 150 bucks)
    Low price is good for us, but hopefully it works more or less as specced - as I only rely on real world performance.

    sound like it is an experimental project.

    I have a working model, worked good over several shoots already. Trying to fund for a 24/1.4. Not many venues got a space to put high up there (I think Raffles City Padang the cocktail area has a bar shelf).
    I can put at the extreme end of Hilton (lift area) and the notebook + USB at the projector screen side, still got some juice left in reserve. But I try not to leave nothing to chance, that is why as long as there is a more robust system (read powerful), I may upgrade.
    Sometimes the clients just tell you that they have a 90 table wedding, and wants this - can do? (happened before). If you say maybe, need to test first - then lose the job....argh.
