supercam 0 Posted November 3, 2012 Hi guys, Have you used Video Transmission System for lift before? I am going to install CCTV for 4 lifts (30 floors each). All inputs are welcome. Share this post Link to post Share on other sites
survtech 0 Posted November 3, 2012 Your best bet is to utilize a spare pair in the elevators' traveler cable, if there are any. You can use baluns for analog or Ethernet-over-UTP adapters with IP cameras. If there aren't any spare pairs in the traveler cable, you can look at wireless but in my experience, that tends to get complex and unreliable. Wireless doesn't work very well for elevator shafts because the car's motion tends to create dropouts in the signal due to reflections in the shaft. Share this post Link to post Share on other sites
vector18 1 Posted November 3, 2012 Do you mean a building or highrise? Do you want analog or IP? Share this post Link to post Share on other sites
