speaker question

Ciku — Mon, 14 Feb 2011 12:26:30 +0800

hai all..i want to ask a few question about speaker. I want to design PA system for announcement and background music.
First step is i choose suitable speaker for the correct area. And after i choose correct speaker, there is a few different wattage of the same type speaker like column speaker that have wattage 20w, 30w ,and 40w. I just know the double of the wattage will gain 2dB for the speaker.

So i got problem how to choose the correct wattage of the speaker to use depend on the how far i can hear the sound and avoid the echo effect. There is any calculation how can i determine the sound coverage/distance from the source speaker?
I need to prove that the speaker with that wattage can cover the area and not to be loud. It's not just like sesuke hati letak je without any calculation or something that can be prove

network and cctv design (cable distance)

Ciku — Mon, 10 Jan 2011 10:44:23 +0800

hi all, i got few question here for my integrated network&poe cctv design

1- Limitation or standard max distance for cable network (RJ45 cat6) how much? I know in theory is 100m, but want to know for practically indoor building design.

2- If i don't want to use fiber when max distance is 100m, is there any solution to extend that cable? i mean like put switch before reach 100m and continues back with standard cable, or is there any repeater that i can use?

3- For indoor with wall and block of room, practically max signal range for wireless router how much? 100m radius also?

4- For outdoor, is there any powerful wireless router (maybe like parabola) that can cover wide area over than 100m with only one point? The system that i design now just use standard a/b/g router with limitation 100m in theory, and need to put few point to cover all of the area

5- For poe cctv camera, if range up to 100m i need to use poe repeater right? no need for fiber cable?
