No need to use something so targeted at the cop camera, just install
rear-facing infrared floods and keep them on all the time. (Cadillac
drivers with the new night-driving, IR, heads-up displays will be
particularly upset..) The IR cut-off filters of most cameras are too broad
to block invisible near IR, so the floods will cause the AGC to greatly
darken the image as described above.
