GunRunner1 0 Posted August 20, 2007 (edited) 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, Edited August 20, 2007 by Guest Share this post Link to post Share on other sites
VST_Man 1 Posted August 20, 2007 - 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.

GunRunner1 0 Posted August 20, 2007 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 Share this post Link to post Share on other sites
survtech 0 Posted August 20, 2007 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). Share this post Link to post Share on other sites
