i need to put together a home surveillance system for my grandmothers house. she is having dopers use her yard as a highway at night. i'm considering a costco system but everyone dumps on them, what other options do i have for around $1000 to 1400. i was hoping for a 3 to 4 camera system. is QSEE w/ sony cameras w/420 lines better than LOREX w/450 lines.
