Ideally a wired camera would record up until its destroyed, even warning the owner of motion. In that case even wearing mask still gives away height/build clothes, direction of approach, numbers etc. If its jammed first then you dont have that potential information, and you are relying on a loss of connection to be recognized as an attack.

Running a jammer as you approach the home would prevent it from uploading video to the cloud of your vehicle (perhaps the license plate can be seen), and your appearance/gait/etc. as you walk up to the house. The baseball bat is just insurance against any locally stored footage.
