Which Nextbase cameras use the Series 2 Hardwire Kit?
Is the Nextbase Piqo compatible?
No. Manufacturer explicitly says the Series 2 kit will not work with Piqo and directs buyers to the Piqo Install Cable.
What connector does the Series 2 kit use?
The currently confirmed models use a 5V Mini USB camera connection. A matching plug shape on its own does not make another camera compatible.
Permanent live vs switched live
A vehicle-side installation may use a permanent supply for parking functions and a switched supply for ignition state. The kit instructions and vehicle documentation—not the connector shape—should guide the installation.
What still needs checking on the vehicle
Fuse number, fuse-tap type and cable routing depend on the vehicle. If those details are not clear from reliable vehicle information, use a competent installer.
