A traditional home security camera system uses wired analog and HD cameras that receive power and connectivity from the house through CAT cables. Wired cameras record and store data to an interior DVR or to a physical chip which can be used to show police the identity of intruders. Newer IP cameras use a static IP address for a network connection point for continually monitoring the premises and reporting the closed feed to a network video recorder service, with no need for physical storage inside the house. These webcams usually offer the best picture quality from the farthest distance, and they take clear shots with pan, tilt, and zoom (PTZ) functions available from multiple angles. Many of these HD cameras also feature sturdy, waterproof glass which resists fog and emits infrared night vision into the surroundings.
