kdmcso8 0 Posted February 13, 2009 I currently have about 20 autodomes on campus, and control them both wireless and wired. During the wonderful times in the economy we are not spending much money. I need to transmit bi-phase about 3000 ft to an adjacent empty wharehouse we own. I plan to shoot the video wireless as I have two transmitters from another old job. I have thought about converting to 232 then transmitting wireless to the autodome but the converter is about 700 bucks. Can I get a line from the phone company to transmit biphase? How far can biphase go? Trenching etc is out of the question as city streets have to be crossed. Anyone know a good "Economical" wireless tx/rx for biphase. This install may be temporary, just another reason to not spend the money. Share this post Link to post Share on other sites
