I need a little education on cat 5 and baluns

[GunRunner1 0]

I no very little to nothing about baluns or cat 5 use.

I'm running the cables 150 ft. to my gaurage I will get power there?

 

I have a pan tilt unit that needs 9 wires.

 

Zoom lens: (zoom in zoom out, focus in focus out, power on of.)

This should be 6 wires?

 

I'll be using 6 24vac camera's

This should be 12 wires.

 

6 camera should need 12 baluns?

 

If I figure right I will need 27 wires?

 

If cat 5 has 4 wires ea. I will need 7 runs.

 

Is this right????

 

Thanks,

- CAT5 has 4 PAIR of wires, 8 wires total.

- 2 Baluns per camera/signal. you can get a combined balun at the DVR end of 4, 8, & 16

- 1 pair frm the CAT5 is require per camera signal

- PTZ? Usually 1 pair is required for the DATA for a PTZ camera. need to know the model and manufacture of the PTZ setup. older PTZ's have more wires, especially the PTZ bases

- 150? missed your point.

- power at garage is ok, but, as long as your cable runs are less then 200ft. you won't have any issue with power in the house.

- why CAT5 on all? I like to use CAT% only when it is required based on install & distance. RG59 Siamese is better in most installs.

 

Baluns are like Women. Most are ok and the really goods ones are expensive.

the 150 was supposed to be 150 foot from house to guarge.

 

Reasons for using cat 5.

1. Allready have 3/4 of a spool.

2. the underground pipe I allready have is no large enough for rg-59 simese and my control cables. But should be large enough if I go with cat 5 cable.

 

O.k. Thanks alot

150ft. is a bit too far for direct PTZ motor and lens control with Cat-5. Typical limits are 50 feet for those functions with 20 gauge wire. Cat-5 is 24 gauge.

 

You could build or buy a relay box and put it in the garage to control the PTZ functions and then use Cat-5 to control the relays. Or you could use RS422/485 on one pair of the Cat-5 to a controller located in the garage. Then you could also use Cat-5 pairs for the video from each camera. You would need one pair per camera (up to 4 cameras per Cat-5 run).
