Check firmware version. Upgrade or revert as necessary, install a micro SD card inside like tangent said. Highly doubt they are defective, there is just a steep learning curve. I really don't think a motion detector is necessary given the video you sent us. The IVS is more then capable of handling that scene if you adjust the settings. If you get it up and running again I am happy to log in remotely and you can watch and I will tweak the settings to what I think they should be and let me know if that fixes false triggers.
