Is that 4B2(3)FWD model number actually on the label of your camera? Usually, numbers/letters in brackets on a part code just means that there are multiple versions of that model. (e.g. 2545FWD-I(W)(S) means there is a -I, -IS, and -IWS version of this model)
Do you have a photo of the camera's label and/or how the model number appears in the SADP Tool?
The /P version is simply a newer version of the ANPR bullet that comes with the ANPR software pre-installed, as far as I am aware both /P and non-/P models should support storing ANPR data direct to a MicroSD card.
