Word for a car accessory that is standard trim, or a low-cost option

I’m looking for a word or two that covers in a vehicle all-round cameras, built-in sonar and radar, etc that may be in the base price or in a low-cost package, and all mount unobtrusively into pre-allocated mountings, but excludes exotic items like LIDAR that sits on the roof of the car and would only be a third-party or specialised purchase. "Off-the-shelf" is close, I think, but is there something better?

The sample heading I am trying to fix currently reads:

Using only in-vehicle conventional sensing devices

"in-vehicle conventional" are the words I want to replace. This is for a formal poster.
