Hardwire the auxiliary camera to the dashcam

Fleet managers can hardwire up to three auxiliary cameras to a single main AI-12 dashcam. This connection is helpful when the auxiliary camera is placed in an area with possible interference to the WiFi signal, such as the back of the vehicle. The auxiliary camera needs a 12V minimum 2A power source.


This feature is currently in BETA. The feature will be fully released after we have finished all validation and testing.


Make sure the dashcam is connected to ignition power instead of constant power.


This installation should be performed by a qualified or professional person only. Working with your vehicle's power system can be dangerous. Consult a professional for guidance.

Before you start, the following equipment is needed:

  • AI-12 dashcam

  • AI-12 auxiliary cameras with a hardwire option

  • USB Type-C to RJ-45 adapter, purchased separately

  • Router (not a hub), purchased separately

  • RJ-45 CAT-6 network cables, purchased separately

  • A pigtail connector, purchased separately.

  • When using a tamper-proof case, some USB Type-C to RJ-45 connectors fit the case while others require an extension USB Type-C cable with a low profile connector, purchased separately


For devices purchased separately, choose from this list. If you want to use a device not on the list, first test it to ensure to works.

To connect using the wired connection:

  1. Connect the USB Type-C to RJ-45 adapter to the dashcam.



    Contact Surfsight support to enable USB power in the dashcam for the RJ-45 adapter to work.


    For dashcams purchased before July 2020, you need to get a new hardwire kit or OBD2 power connection. Using an older kit or power connection may cause the dashcam to remain in standby.

  2. Connect an RJ-45 network cable to the USB Type-C to RJ-45 adapter.



    Protect the RJ-45 connection with the waterproof connector supplied with your camera.

  3. Connect the other end of the RJ-45 network cable to the LAN port of your router.



    Protect the router in your vehicle. For example, place the router in a plastic enclosure to protect against water damage.

  4. Connect the router to the vehicle ignition power using a pigtail connector.

  5. Connect the auxiliary camera to the vehicle ignition power.

  6. The auxiliary camera is automatically added to your dashcam.


    Connect the dashcam to ignition power instead of constant power.
