but if someone recognizes the unit or knows you have it, they can just take the card with them?The camera has an SD card, just like a digital cam. It loads and unloads on the side of the light and can be taken out and viewed on a PC, or an included cable will attach to the unit and then to the PC (card doesn't have to be taken out of the light). The motion light also has 3 different warnings alerting trespassors, or it can remain silent (like mine). I used my existing front porch light fixture and replaced it with this motion camera. Well worth the investment.
I was hoping that it transmitted the images wirelessly to a unit somewhere else hidden on the inside.
I would rather run wires.
