So Fun facts about digital cameras like these: Strong infrared leds at night blind them completely. They sometimes even switch into daymode and become useless at night. Also, lasers are usually not enough to destroy the ccd sensor but only cause small dots to appear[0]. But a Spraycan on a stick can be very effective and of course a silenced airgun for those hard to reach places can be very effective.
