Detector for predators or petty egg thieves, or a small motion sensor to detect such activities.
I actually second this idea+Akinsola you can create sort of an alarm system with a camera to keep out wild animals and poachers
+Harrison Owens (Community Mentor) CCTV can be incorporated provided that the system will be further enhanced. :)
What kind of sensor +Akinsola
@Amos Fiesta A PIR sensor could achieve but not sure it would be sufficient, it can trigger an alarm system if need be.
