Yes he agrees with you, I think they were best he could afford.
In his words
These cameras were chosen for this project not because they are the best possible equipment available for this purpose, but because they were the best possible equipment available that are within my budget. I installed these cameras well-aware of their functional limitations and knowing that they were not designed to be activated at a distance of greater than 100 yards, but all the while essentially hoping for a miracle. I assumed that highly intelligent beings who might cooperate in this effort would either maneuver their craft in very close to the house to trigger the camera, or that they would be capable, somehow, of employing a means to overcome the design limitations of the cameras and trigger the cameras from a distance – perhaps by using a laser, for example. Is this what happened on November 4?
