What is PCIe-GIE74P PoE Budget Mode？

The PoE budget mode is to ensure product power supply security, PoE automatically cuts off when PoE power is exceeded.

  • PCIe-GIE74P PoE Power budget

    1、Max 20.0W w/ PCIe slot only.

    2、Max 61.6W w/ PCIe slot and 4-pin Molex connector.

  • How does PCIe-GIE74P reserve PoE Power Budget？

    • PoE Power Consumption Mode for variable power budget

      PCIe-GIE74P will detect the camera’s real power consumption to reserve PoE power budget.

    • PoE Class Mode for fixed power budget

      PCIe-GIE74P will detect the camera’s PoE class to reserve PoE power budget.

  • How to setting Power Budget Mode？

    1、Using API of AVS_PoESetPowConsumCalcModel.

    Customer can configure settings according to user scenarios.

    2、Execute POE Budget Mode Setting Tool.

    This tool can set multi-card to the power consumption mode at one time.
    Step2、 Install AVS SDK
    Step3、 Open Folder “POE_tool”.
    Step4、 Execute “Sample.exe”.

    • Example、User’s Situation.

      If I want to connect 3 GIgE cameras, and I didn’t connect PCIe-GIE74P’s 4-pin Molex connector…

    • By PoE Power Consumption Mode

      If this camera’s real power consumption is 5 watts, PCIe-GIE74P will reserve 6 watts per camera. PCIe-GIE74P has power budget of 20 watts. 3 (cameras) x 5 (watts) = 15 (watts)

      PCIe-GIE74P can power 3 cameras.

    • By PoE Class Mode

      If this camera’s PoE class is “2”, according to the PoE class of the PoE standard, PCIe-GIE74P will reserve 7 watts per camera. PCIe-GIE74P has power budget of 20 watts. 3 (cameras) x 7 (watts) = 21 (watts)

      PCIe-GIE74P can only power 2 cameras, cannot power the third camera.

If you want to provide more than 20 watts of power, you need to connect the 4-pin Molex connector of PCIe-GIE74P.
