Connecting to Power and External Devices

CAUTION — Be careful to only connect power to the Auxiliary Power Wires or the camera will be damaged.

If PoE is not available, the camera may be powered through the auxiliary power cable using either 24 V DC or 24 V AC. The power consumption information is listed in the product specifications.

To power the camera, connect the two power wires to the red and black auxiliary power wires. The connection can be made with either polarity.

WARNING — This product is intended to be powered by a UL Listed Power Unit marked “Class 2” or “LPS” or “Limited Power Source” with output rated 24 V AC +/- 10%, 105 VA min. or 24 V DC +/- 10%, 75 W min.

Power supplies and external devices are connected to the camera through the power and I/O wires. The pinout for the I/O and power wires is shown in the following diagram:

Figure 7: Example application.

  1. Pink (AUDIO_IN) — Audio Input (line level)

    An external power amplifier should be used when connecting speakers and microphones, as shown in the diagram.

    1. Black — Audio Ground
  2. Light Green (AUDIO_OUT)— Audio Output (line level)
    1. Black — Audio Ground
  3. Light Blue (GND) — Ground for digital inputs and outputs.
  4. Yellow (RI_1)— Digital Input, Relay 1. The input voltage must be below 0.7 V to register as a low input. The input voltage should not exceed 5 V when high.
  5. Orange (RI_2)— Digital Input, Relay 2
  6. Light Green (RI_3)— Digital Input, Relay 3
  7. Brown (RI_4) — Digital Input, Relay 4
  8. Purple (RO+)— +5V power output from camera. For the maximum allowable current, see Specifications.
  9. Blue (RO_1) — Digital Output,
  10. Green (RO_2) — Digital Output
  11. Pink (Reserved) — Reserved Wire, do not connect.
  12. Red (DC) — Auxiliary Power Wire, accepts DC and AC power.
  13. Black (DC) — Auxiliary Power Wire, accepts DC and AC power.
  • 1 — External relay power supply
  • 2 — Optional 24 V AC (RMS) or 24 V DC Aux. power supply
