What are network video recorders?

A Network Video Recorder (NVR) is a device used to record and store video footage from IP cameras. Unlike DVRs, which work with analog cameras, NVRs receive digital video from IP cameras through a network (Ethernet or Wi-Fi). It records the footage to internal storage, allowing you to manage, view, and retrieve footage from a centralized system.

NVRs work by receiving video streams from IP cameras through your local network, which is connected via Ethernet or Wi-Fi. The NVR stores the footage on hard drives or other storage devices, and manages the video feeds from multiple cameras at once. Through the NVR, you can watch live streams, review recorded footage, and adjust settings remotely using a computer, mobile app, or connected monitor.

What is the difference between an NVR and DVR?

The main difference between a Network Video Recorder (NVR) and a Digital Video Recorder (DVR) is the type of camera systems they work with. NVRs are used for IP cameras, which send digital video over a network, allowing for better image quality, flexibility, and remote viewing. DVRs work with analog cameras that transmit video via coaxial cables. Since NVRs don’t require the same type of cabling as DVRs, they’re typically more scalable and easier to install.

Do I need an NVR for my IP camera?

Yes, an NVR is generally required if you want to store and record video from IP cameras. While you can view live video from an IP camera directly, an NVR is essential for managing and storing video over time. It centralizes the footage from multiple cameras, allows for playback, and provides features like motion detection and remote access. If you don’t plan to store recordings locally and only need to monitor live video, you could use a cloud service or other video management software.

How many cameras can I connect to an NVR?

The number of cameras you can connect to an NVR depends on its channel capacity. We carry NVRs that can support 4, 8, 16, 32, 64, or even 128 cameras. When selecting an NVR, make sure to choose one that offers enough channels to accommodate the number of cameras you plan to install. If you need to scale up in the future, look for an NVR with expansion options.

What storage options are available?

NVRs typically use hard drives (HDDs) to store footage locally. You can install one or more drives depending on the NVR’s capacity and your storage needs. Some NVRs also support external storage devices, such as USB drives or network-attached storage (NAS), for additional space. Additionally, many NVRs offer cloud storage options, allowing you to back up footage offsite for extra security and remote access.

How much footage can an NVR store, and what happens if it runs out of space?

The amount of footage an NVR can store depends on several factors, including the storage capacity, video resolution, frame rate, and the number of cameras. Higher resolution videos (like 4K) will require more storage space. If the NVR runs out of storage, it will generally start overwriting the oldest footage to make room for new recordings, unless you have set specific storage limits or retention policies. To extend storage, you can add more hard drives or use cloud storage.

What is Power over Ethernet (PoE)?

Power over Ethernet (PoE) is a technology that allows both power and data to be transmitted over a single Ethernet cable. Some NVRs have built-in PoE ports, which allows the NVR to supply power to PoE-supported IP cameras directly through the same Ethernet cable used to transmit data. This simplifies installation by reducing the need for separate power cables and outlets for each camera, making it ideal for large installations or outdoor setups where power sources are hard to reach.

How do I choose the right NVR for my facility?

When choosing the right NVR for your facility, consider the following factors:Camera compatibility: Make sure the NVR works with the type of network camera you plan to install.Storage capacity: Determine how much storage space you need based on the video resolution, frame rate, and retention period.Number of channels: Choose an NVR that can accommodate the number of cameras you need, with room for expansion if necessary.Power over Ethernet (PoE): If you need a simpler installation process, choose an NVR with built-in PoE ports to power your cameras via Ethernet cables. If you’re unsure, get in touch with one of our security experts for guidance on selecting the best NVR for your IP video surveillance system.
