It sounds like the manufacturer of your camera has their own software installed, and exports in some format that wasn't clear in the information you posted.
LabVIEW, in their Vision Acquisition Software, supports the GenICam protocols for USB and TCP/IP cameras. LabVIEW also has "Picture" VIs that can read (and display) various Image formats, such as .PNG, .JPG, and others. They also offer the Vision Development Module that allows additional specialized Image-processing routines, should they be required for your application.
LabVIEW definitely supports TCP/IP and VISA protocols for acquiring data, without needing any additional Modules. Whether or not you will need any of their add-on Vision products is unclear without knowing (a) what the existing ANPR camera provides, and (b) what additional stuff you need to do that the Camera manufacturer doesn't provide. Have you looked at their SDK?
