Cameras
The camera decides what you see. Pick the right body style for each spot so you never regret placement.
PTZ cameras rotate, tilt, and zoom on command. Powerful, but only pay off when you have wide areas and an active operator or preset patrol.

Cabling & Power
CAT6 carries video + power for IP cameras (PoE) up to 100 m on a single cable. Coax still wins for long analog runs.
Baluns let you run analog HD cameras over cheap CAT6 instead of coax — perfect for retrofits and long runs.
A central 12V SMPS powers all cameras from one box — easier to protect, easier to service. Individual adapters are only fine for 1–2 cameras.
