Can you add additional cameras to your dashcam setup?

A dashcam’s main unit (the “front camera” or “base recorder”) can often accept extra cameras through dedicated input ports or extension cables.
Each add-on becomes an extra recording channel (for example, turning a 1CH dashcam into a 2CH or 3CH system).

➤ Think of it like this:

The main dashcam still handles power, recording, storage, and sync, while the added cameras are “slaves” that send their video feed back via cable.
