Thermoplastic Polyolefin Elastomer (TPO (POE)). Thermoplastic polyurethanes (TPU) are a class of polyurethane plastics with many useful properties, including elasticity, transparency, and resistance to oil, grease and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
Power over Ethernet (PoE) is a way to power cameras with an Ethernet cord, which also gives the camera direct network access. Along with providing stable network connections, PoE also makes installation easier by only requiring one cable.P cameras wired for PoE have a special power switch in them which can use the power sent over the Ethernet cord, while cameras without this switch will simply get the network connection and no power.
