Internet Protocol cameras, also called IP cameras or network cameras, provide digital video surveillance by sending and receiving footage over the internet or local area network (LAN). Like their name suggests, IP cameras connect to a network through WiFi or a Power over Ethernet (PoE) cable. They’re often used with network video recorders (NVRs) and sometimes digital video recorders (DVRs), making them a common solution for enterprise video surveillance.

A NVR (network video recorder) is considered a complete Internet Protocol camera recording system and is mostly used in Internet Protocol video surveillance systems.A network video recorder does not use any dedicated hardware to capture video but uses specialized software on a dedicated device. It can record as well as access the recorder image and live view. Seen as the successor to the digital video recorder, the network video recorder can be operated remotely via the Internet or LAN, providing great flexibility for users.

DVR(Digital Video Recorder) is a device that records video from a dozen or more surveillance cameras onto a hard disk. Frame rate can be changed from real time to time lapse to save storage space. Digital recorders are more flexible than earlier analog VHS tape systems, and video can be easily transmitted over a computer network.

PTZ Camera (Pan-Tilt-Zoom Camera) is a camera that supports remote control of direction (panning and tilting) and zooming (increasing and decreasing). PTZ cameras are designed for their specific application. Many camera lines offer unique features including the ability to pan, tilt and zoom to a preset position, providing an easy workflow. Camera presets are usually stored in the camera and can be recalled to robotically move the camera to a specific location.

WiFi security cameras have brought a new level of freedom and flexibility to the world of safety and surveillance. Because they can operate apart from a wired network, you have the ability to install them farther and wider than ever before. This means that you can have all the power of high-end video security — including 4K resolution, high-performance sensors, advanced zoom, motion detection, and more — even for applications like construction sites, events, parking lots, or temporary facilities that are out of reach from ethernet cables. With a wireless WiFi security camera system, you get everything you need plus the versatility of an untethered experience.
