NVR Camera System

NVRs are used in CCTV systems to provide reliable, long-term video recording across multiple cameras. Unlike relying on individual camera storage, an NVR keeps recordings in one place, making it easier to retrieve footage after an incident, manage storage capacity, and maintain continuous surveillance across a property.

Camera Resolution: Choose 4K 8MP, 12MP, or 16MP cameras based on the level of detail needed. Check the NVR's maximum supported resolution, as not all models support 16MP cameras.

Channel Count: An 8-channel NVR suits systems with up to eight compatible cameras, while 16-channel models allow greater coverage. Check both the channel limit and PoE port count, as they are not necessarily the same.

Storage Capacity: A 2TB HDD may be sufficient for a small system, while 4TB or larger capacities are worth considering for more cameras or longer recording periods. Compare retention times using camera count, bitrate, and recording mode.

Remote Access: Look for live viewing, multi-camera playback, and recording downloads through a mobile app or PC. Check whether remote playback and event search are supported by your chosen NVR.

Smart Detection: Choose cameras with person and vehicle detection for entrances and driveways. Check whether the NVR supports filtering recordings by detection type, rather than requiring manual review of the timeline.

Local Storage and Subscription: Confirm whether an HDD is included, the maximum supported storage expansion, and whether continuous recording works without Internet. Check that local recording and playback do not require a subscription.

For most modern security setups, yes. An NVR works with digital IP cameras, supports higher resolutions, and allows easier remote viewing than traditional DVR systems.

A DVR uses analog cameras and coaxial cables, while an NVR is better suited for PoE cameras, smart detection, and flexible installation.

No. An NVR security system can record video locally without internet as long as the cameras are connected to the recorder.

Internet is only needed for remote viewing, push notifications, firmware updates, or accessing footage from your phone when you are away.

To connect CCTV cameras to a Reolink NVR, connect the cameras to the recorder, complete the initial setup, and add the cameras through the NVR's interface. The connection method depends on whether you use PoE or Wi-Fi cameras.

Step 1: Connect the Cameras to the NVR

For PoE cameras, connect each camera directly to a PoE port on the NVR using an Ethernet cable. The cable carries both power and video data. For compatible Wi-Fi cameras, connect the cameras and NVR to the same local network and provide separate power where required.

Step 2: Connect the NVR to a Monitor and Router

Connect the NVR to a monitor using HDMI or VGA, and attach a USB mouse. Connect the NVR's LAN port to your router with an Ethernet cable, then power on the recorder and complete the initial setup. Follow the Reolink PoE NVR initial setup guide for detailed instructions.

Step 3: Add Cameras to the NVR

On the NVR's connected monitor, go to Settings > Channel and click the + icon in an available channel. Select the camera from the detected devices and enter its password if prompted. Cameras included in a compatible Reolink NVR kit may connect automatically.

For detailed instructions, see How to Add Reolink Cameras to Reolink NVR. If you use a Wi-Fi NVR, refer to the Reolink Wi-Fi NVR camera setup guide.

Step 4: Check Live View and Recording

Once the cameras appear on the NVR's live view, check their video feeds and configure the recording schedule. You can also add the NVR to the Reolink App to access live video and recordings remotely.

An IP camera is a standalone network camera that captures and transmits video, while an NVR CCTV system connects multiple IP cameras to a recorder for centralised recording and management. An IP camera can monitor a single area and store footage locally if supported, whereas an NVR system is better suited to monitoring multiple locations with continuous recording and larger storage capacity.

For example, a single IP camera may be sufficient for a front door or garage, while an NVR CCTV system is more practical for covering entrances, driveways, gardens, and other areas of a property.

NVR camera systems are suitable for homes and businesses that need continuous recording across multiple locations. Common applications include:

Detached and Semi-Detached Houses: Use 4–8 cameras to monitor front entrances, driveways, garages, gardens, and side access points. An 8-channel NVR also leaves room for future expansion.

Retail Shops and Supermarkets: Position cameras at entrances, checkout counters, aisles, and stockrooms to monitor customer activity, investigate incidents, and review footage from different areas.

Offices and Commercial Buildings: Cover reception areas, corridors, stairwells, and building entrances. A 16-channel NVR can accommodate cameras across multiple floors or departments.

Warehouses and Industrial Sites: Monitor loading bays, storage areas, delivery entrances, and perimeter access points. Continuous recording helps review deliveries, vehicle movements, and incidents outside working hours.

Car Parks and Large Driveways: Combine wide-angle cameras for general coverage with higher-resolution or optical zoom cameras at vehicle entrances to capture more detail at key locations.
