    Long range RFID product

    what application are you doing? it seems RFID may not be the tech of your distance required.
  3. long range probably at 13.56MHz up to 900 MHz calling UHF, LF 125KHz unable to reach long 1 metre probably the longest I seen for this range. what do you want to achieve, see if you can help. Dennis ASIS Member

  11. Yes, I think I use a wrong wording, PoE is PoE with its standard. My primary purpose is to make use of one Cat.5 cable for both signal and power so as to save cabling cost or even make use the existing network cabling.
  12. I am wondering if anyone of you tried to make of Cat5 cable with proper wiring to power up an IP camera (using 12V DC)? Because only 2 pairs of wires enough for data comm, is it possible to use another pair for 12V DC power. And at both ends. Is it really possible? any limitation or risk? or in the market there is such a small device for this special wiring? Thanks. Rgds, Dove
