Connecting to Power, Audio, and External Devices

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 brown and blue auxiliary power wires. The connection can be made with either polarity.

WARNING — This product is intended to be supplied by a UL Listed Power Unit marked “Class 2” or “LPS” or “Limited Power Source” with output rated:

  • With IR LEDs: 24 V AC ± 10%, 74 VA minimum, or 24 V DC ± 10%, 52 W minimum.
  • Without IR LEDs: 24 V AC ± 10%, 37 VA minimum, or 24 V DC ± 10%, 26 W minimum.

For more information on using PoE to power the camera, see Connecting Cables.

Pigtail Connector and Wires

Power supplies, audio devices, and external devices are connected to the camera through the power, audio, and I/O pigtail. The following diagram and table shows the I/O, audio, and power pigtail connector and wires:

Wire Color Description
1 Blue AUX1 Power, accepts either polarity
2 Brown AUX2 Power, accepts either polarity
3 White Audio IN
4 Yellow Audio GND
5 Green Audio OUT
6 Purple Relay OUT
7 Gray Relay GND
8 Red Relay IN

Wiring Audio, I/O, and AUX Power

The connections for the I/O, audio, and power wires is shown in the following diagram:

  1. Brown — AUX1 Auxiliary Power wire, accepts either polarity
  2. Blue — AUX2 Auxiliary Power wire, accepts either polarity
  3. White — Audio Input (line level)

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

  4. Yellow — Audio Ground return
  5. Green — Audio Output (line level)
  6. Purple — Relay Output: When active, Output is internally connected with the Ground. Circuit is open when inactive. Maximum load is 25 V DC, 100 mA.
  7. Gray — Relay Ground return
  8. Red — Relay Input: To activate, connect the Input to the Ground wire. To deactivate, leave it disconnected or apply between 3-15 V.
  • * — Relay
  • ** — Switch
  • M — Microphone
  • S — Speaker
  • AUX1 — Brown Auxiliary Power wire
  • AUX2 — Blue Auxiliary Power wire

Non-Seamless Failover

  • If the camera has power available from both an external Aux power supply and a PoE PSE (Power Sourcing Equipment) device, the camera will draw power from Aux.

  • When the camera is using Aux power, PoE power negotiation is inhibited.

  • If the camera loses Aux power, the camera will power-off while waiting to transition to PoE power.

  • If the external Aux power re-energizes, the camera might reboot while transitioning back to using Aux power. The camera might not reboot if the external Aux power supply reacts quickly enough to the increase in load.

  • Ensure that sufficient power is manually reserved on the PSE, as the camera will not request PoE power until the camera loses Aux power.
