I live in India, on a rough neighborhood riddled with antisocial behaviours including drug intake and people relieving themselves on the street just outside my house, theft of properties including automobiles and other items from my house. I am planning to install a full CCTV setup: 8 IP cameras with motion detection and night vision connected via LAN cables and an hard disk to record couple of weeks. Is it worth it? What do I need to take care of for this setup? Do I need extra protection from theft and damage from the local residents? Also suggest the insurance policies to go with if the setup is damaged or stolen.

Much thanks
