I've recently had a number of false alarms from an outdoor security beam. I'm interested to know what's causing it, having seen a number of small nocturnal visitors - rats, a genet, the neighbour's cat and a bush baby - in the near vicinity of this beam. We also have a small neighborhood troop of vervet monkeys, while the neighbour's camera caught a baboon in their driveway a while back. I have one camera up at the moment - an EzViz H3C, which is remarkably good at detecting people and notifying me, but is pointing at another part of the property. I am still planning on installing a couple more cameras, but would like to know if there's a trick (or a better camera) for catching small animals in action.
