...rolling out a new IP-based CCTV network that must protect both indoor and outdoor areas of our facility. The job begins with a full site survey—virtual walk-throughs and existing floor plans are available—to map optimal camera positions, cabling routes, and NVR locations. Because the entire backbone will run on Ethernet, you will need to size and specify PoE switches, storage capacity, and any wireless bridges needed for hard-to-reach exterior zones. Once the bill of materials is approved, I expect you to handle or oversee physical installation, perform all network configuration (subnetting, VLANs, port-forwarding for secure remote viewing), and fine-tune the VMS so live and archived footage streams smoothly from every camera.
