My sisters house was robbed Christmas evening :(
I talked with her about making a surveillance system for her. The idea is to have a system that detects intruders and then send a SMS to you while streaming it to a private website.
The hard part:
How and where do I storage the data from the camera so it's streamable?
I think I can manage to do the streaming, website and SMS server, but I need the data (fundamentation).
For a do-it-yourself system here is a rudimentary idea:
Equipment
On this NAS, designate a folder to store the videos into.
Write a .Net program that will monitor the folder for new files. If one is found, then send email / SMS to desired addresses.
You should know that motion sensing cameras are easily tripped by fruit flies, spiders, pets, etc.
