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. In the modern market, many different types of IP cameras are produced for you to choose from such as HD IP Camera, AI IP Camera, PTZ IP Camera, etc. and other cameras like Full Color Camera and Analog Camera.
Another equipment similar to camera is DVR. A DVR (digital video recorder) is a device or service used for recording and storing videos. Learn more about what a DVR is to help determine if you need one for your TV. DVRs became popular in the late 1990s with the introduction of TiVo. Watching stored video allows you to rewind and fast forward at will. If you are watching live TV, you can pause and pick up where you left off. The DVR also has many different specifications like 4CH DVR, 8CH DVR, 16CH DVR, etc.
DVRs can be integrated into the set-top box supplied by your cable or satellite provider, but they are also sold as standalone units. DVR units you buy store videos on a hard drive, but cloud DVR services keep your recordings on a remote server owned by the service provider. You can adjust the number of hours you can store on a DVR by lowering the video quality settings.
DVRs are primarily used to record movies and TV shows so you can watch them later. You can typically set up your DVR to record specific shows or events when they air. If you have a favorite show, you can have it automatically record only new episodes and delete old ones. DVRs with multiple tuners built-in can even record multiple channels simultaneously.
The DVR sets aside buffer space on the hard drive so it can constantly record live TV. This makes it possible to pause and rewind live broadcasts. If you miss the beginning of a show, you can start from the beginning and skip through commercials.
Aside from recording TV, there are also DVRs for recording live camera feeds. These devices are typically used as part of security systems to store surveillance footage.
