I have a Trivision NC-336 HD camera w/Blueiris. For some reason it won't pick up people walking 30 feet in front of it. My cam points southwest, I have trees on the south and east of me and when it's sunny in Seattle (sometimes!) I get hundreds of pics of shadows moving across the lawn. I tried filtering out most common areas with zones and hot spots but I still miss people walking by but can record all kinds of shadows. Yes, I have 4.3.2 version. May go try iSpy if I can't get this S/W to work!!! Very frustrated....
