Connecting to Power and External Devices

Important: Be careful not to connect auxiliary power to the audio input wire or the camera will be damaged. Although both the audio input wire and auxiliary power wire are brown, the auxiliary power wire is distinguished by its thicker wire gauge and AUX PWR label.

If PoE is not available, the camera may be powered through the auxiliary power cable using either 12 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 12 VDC or 24 VAC, 8 W min. or Power over Ethernet (PoE), rated 48 VDC, 8 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 1: Example application.

  1. Brown — Audio Input (line level)

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

  2. Yellow — Audio Ground
  3. Green — Audio Output (line level)
  4. Grey — Ground
  5. Red — Digital Input
  6. Pink — Digital Output
  7. Purple — Reserved Wire, do not connect.
  8. White — Reserved Wire, do not connect.

  • AUX1 — Brown Auxiliary Power Wire, labeled AUX PWR
  • 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.
