cheap and effective way to do v surveillance, mitigating the possibility of someone deleting the event, what are my best options?
I dont mind buying professional security system, but I would like to use my old laptops as surveillance system, and somehow lock it so the intruder would not just turn the thing on and delete the file. Worst of it we have eraser and soft for trimming for years so permanent deletion is not a problem for the intruder with right knowledge.
