NVR Recorders - Onvif Protocols, Centralized E-map
Build a reliable, easy-to-manage IP surveillance system with the right network pieces from one place. Start with your cameras (IP cameras) and recording (NVR recorders), then connect everything with network switches (PoE simplifies power and cabling). Extend or adapt runs using network devices like PoE injectors, splitters, and long-distance extenders. No Ethernet nearby? Powerline networking can bridge from a wall outlet. For Wi-Fi add-ons, see network routers. Finally, manage live view, playback, alerts, and user access with video management software—most options offer mobile apps and simple setup for homeowners.

Network Recorder Frequently Asked Questions
What is a Network Video Recorder (NVR)?
A Network Video Recorder (NVR) is a device that records video footage from IP cameras over a network. Unlike traditional DVRs, which are designed for analog cameras, NVRs work with digital video streams, allowing for higher resolution recordings and more flexible camera placement.
How many cameras can I connect to an NVR?
The number of cameras you can connect to an NVR depends on its specifications. Most NVRs have a specified channel limit, such as 4, 8, or 16 channels. Ensure the NVR you choose matches your surveillance needs and can support the number of cameras you intend to install.
What resolution can I expect from an NVR?
NVRs can support various resolutions, typically ranging from 1080p (2MP) to 4K (8MP). The resolution you choose will affect the clarity and detail of the recorded footage, with higher resolutions providing better image quality, especially for identifying faces or license plates.
Do NVRs require a hard drive?
Most NVRs require a hard drive for storage, though some models are sold without one. The hard drive capacity you need will depend on the number of cameras, their resolution, and how long you want to retain recorded footage. Consider a model that allows for easy upgrades if needed.
What is PoE and why is it important for NVRs?
Power over Ethernet (PoE) is a technology that allows network cables to carry electrical power along with data. This is important for NVRs because it simplifies installation by eliminating the need for separate power supplies for each camera, making it easier to set up and maintain your surveillance system.
