Stealth Laboratories STV-04B 4 power outputs. Total power 4A at 24V AC or 2.5A at 12V DC. 4 passive baluns. Power: The STV-B series allows on-site selection of 12V DC or 24V AC operation by simply moving a switch. A failsafe option allows disabling of the 24V AC option if 12V DC cameras are connected. Power supply outputs are protected by self-resetting SmartFuses. Outputs are fused at 1.85 Amps. Video: Each balun has a range of 1000 ft over UTP or 2000 ft over CAT5e cable. Use with TW-1000A baluns at the cameras. Frequency response: : DC to 12 MHz Insertion losses: max 0.5 dB at 5 MHz. Common mode rejection ratio: =60 dB from 15 KHz to 5 MHz. Impedance coaxial side: 75 Ohms. Impedance balanced side:: 100 Ohms ± 20 percent. Maximun signal voltage: 1 VPP
