Maxim cabling distances

[Lilern 0]

Hi everyone! Im new here and is great what you have!.

I want to discuss the maxim distances that u can reach with the different cables.

 

1.Signal in coaxial RG59

2.Voltage in siamese 18x2 24VAC 1A

3.Voltage in siamese 18x2 12VDC 1A

4. Voltage in UTP Cat5E 12VDC 1A

 

Please help me with this.

 

Regards

RG59/U - 750-1000 feet, depending on who you listen to.

18/2 @ 1A (24VAC) - 150-180 feet

18/2 @ 1A (12VDC) - 70 feet

 

I don't understand Question #4. Here is a link to a good calculator: http://www.nvt.com/content.php?func=distcalc

^Not to confuse the issue, but those numbers may vary a bit as well, depending on the camera... ie. a dual-voltage camera that will work at 12VDC/24VAC, will usually work over a range of voltages, and some I've seen will actually work at anything from 10-28V, AC or DC... so especially with a 24VAC supply, those would be forgiving of a significant drop over a longer distance.

 

BTW, 1A is a LOT of juice for a single camera... most run well under half an amp, even with IR. Also, a dual-voltage camera that draws 1A at 12VDC would only draw about 500mA at 24VAC, which would increase the usable distance as well.
