Every channel checked for recording integrity. Playback tested, storage calculations confirmed against your retention target, and app access verified on your device.
What an NVR does and why it matters
An NVR - Network Video Recorder - receives digital video streams from IP cameras over your local network and writes them to a hard drive. Unlike older DVR units that converted analogue signals to digital, an NVR handles natively digital footage. This means higher resolutions (4MP, 5MP, 8MP), better compression (H.265+), and smart detection features that run on the recorder or on the camera itself. Every system we install in Leicester is built around an NVR, not a DVR.
The NVR also handles remote access. Once configured, you can view live feeds and play back recorded footage on your phone from anywhere. The recorder connects to your router, and you access it through a manufacturer app - no cloud subscription required, no monthly fees. The footage stays on your hard drive, on your property. We configure this during installation and test it before we leave.
Choosing the right NVR is not just about channel count. It determines your maximum resolution per channel, total recording bandwidth, smart detection capability, and how many hard drives you can install. Getting it wrong means either paying for capacity you do not need or, worse, running out of channels or storage within a year. We size every NVR to the job with room for reasonable expansion. For a full breakdown of CCTV system components, see our equipment overview.
Channel count and hard drive sizing
NVRs come in 4-channel, 8-channel, and 16-channel configurations. A 4-channel unit suits a typical Leicester home - front, rear, side, and driveway. An 8-channel unit covers larger homes, semi-detached properties with multiple access points, or small commercial premises. 16-channel NVRs are for commercial sites - shops, warehouses, offices, and multi-unit buildings - where eight or more cameras are needed. We always recommend at least one or two spare channels so you can add a camera later without replacing the entire recorder.
Hard drive sizing is driven by three factors: camera count, resolution, and how long you want to retain footage. A four-camera system at 4MP recording continuously to an H.265+ codec needs roughly 1TB per seven to ten days. A 2TB drive gives you around two to three weeks of retention. A 4TB drive pushes that to five to six weeks. For a 16-camera commercial system at 8MP, you are looking at 6TB to 10TB depending on whether you record continuously or use event-triggered recording. We calculate this precisely for your setup and include the recommendation in your quote.
Surveillance-grade drives - WD Purple and Seagate SkyHawk - are designed for the constant write cycles that CCTV recording demands. Desktop drives are not rated for this workload and fail significantly sooner. Every NVR we supply includes a surveillance-grade drive from day one. For more detail on how storage and specs interact, our hardware specification guide covers the numbers.
PoE NVR vs standalone NVR with switch
A PoE NVR has built-in PoE ports - each camera plugs directly into the back of the recorder with a single Ethernet cable that carries both power and data. This is the simplest setup and works well for systems up to eight cameras where the NVR is located centrally. No separate switch needed, fewer components, and fewer potential points of failure. For most Leicester homes, a PoE NVR is the right choice.
A standalone NVR paired with a separate PoE switch makes more sense for larger or more distributed installations. If cameras are spread across a large property or commercial site, running every cable back to the NVR is impractical. Instead, cameras connect to one or more PoE switches positioned closer to the camera clusters, and the switches connect to the NVR over the local network. This also allows the switch and NVR to be in different physical locations - the switch in a comms cabinet near the cameras, the NVR in a secure server room or office.
The standalone approach also gives you more flexibility on PoE budget. A built-in PoE NVR has a fixed power budget across its ports. A dedicated managed switch lets you allocate PoE power per port, monitor power draw, and support cameras with higher power requirements like PTZ units or cameras with heaters. For systems above eight cameras, or where network infrastructure already exists, we typically recommend the standalone configuration. Our blog on PoE vs Wi-Fi covers why PoE is the foundation of every system we build.
Recording modes and retention
Continuous recording writes footage 24/7, regardless of activity. This is the simplest and most reliable approach - nothing is missed, and there are no gaps. The trade-off is storage consumption. Event-triggered recording only writes when motion or smart detection is triggered, dramatically reducing storage use. Most systems we install use a hybrid approach: continuous recording at a lower quality with high-quality snapshots and clips triggered by person or vehicle detection events.
Smart detection on modern NVRs lets you filter playback by event type. Instead of scrubbing through 24 hours of an empty driveway, you can jump straight to "person detected" or "vehicle detected" events. This is powered by AcuSense or similar AI classification, either on the camera or on the NVR. We configure detection zones and sensitivity during commissioning so you get useful alerts without false triggers from cats, headlights, or tree branches.
Retention period depends on what you need the system for. Residential customers in Leicester typically want two to four weeks of footage. Commercial clients - especially those with insurance or compliance requirements - often need 30 days or more. We calculate the exact drive size needed for your target retention and build it into the quote. If your needs change later, adding a larger drive or a second drive bay is a straightforward upgrade.
Local recording vs cloud storage
Every NVR we install records to a local hard drive on your premises. The footage is yours - stored on your property, under your control, with no third party involved. There are no monthly fees, no subscriptions, and no dependence on your broadband connection for recording to work. If your internet goes down, the system keeps recording without interruption.
Cloud storage - used by consumer systems like Ring and some commercial platforms - sends footage to remote servers over your broadband. This introduces a dependency on your internet connection, a recurring monthly cost, and a privacy consideration around who has access to your video data. For a detailed comparison of consumer cloud systems versus professional local recording, see our Ring vs professional CCTV guide. We build systems that work independently of your broadband because that is what reliable CCTV requires.
Pricing
NVR costs vary by channel count, drive size, and whether the unit includes built-in PoE ports. A 4-channel PoE NVR with a 2TB drive for a home system costs significantly less than a 16-channel standalone NVR with dual 6TB drives for a commercial site. We include the recorder, drives, and full configuration in every system quote. No separate line items or surprises.

Frequently asked questions
- What is the difference between a DVR and an NVR?
- A DVR converts analogue camera signals to digital for storage. An NVR receives natively digital footage from IP cameras. NVRs support higher resolutions, better compression, smart detection, and remote access as standard. Every system we install uses an NVR.
- How much hard drive space do I need?
- It depends on camera count, resolution, and how long you want to keep footage. A four-camera 4MP system needs roughly 2TB for two to three weeks of continuous recording, or 4TB for five to six weeks. We calculate the exact requirement during the survey and include it in your quote.
- Should I get a PoE NVR or a standalone NVR with a separate switch?
- For most homes with up to eight cameras, a PoE NVR is simpler and more cost-effective. For larger or distributed installations where cameras are spread across a site, a standalone NVR with a dedicated PoE switch offers more flexibility and easier cable management.
- Can I access my NVR remotely on my phone?
- Yes. We configure remote access during installation using the manufacturer app. You can view live feeds and play back recorded footage from anywhere. This runs through a secure P2P connection - no cloud subscription needed and no monthly fee.
- What happens if the hard drive fails?
- Modern NVRs monitor drive health via SMART data and alert you to problems before total failure. Surveillance-grade drives are rated for constant recording, but they do not last forever. If a drive fails, it can be replaced without swapping the entire NVR. We use hot-swappable bays where the hardware supports it.
- Do I need a RAID setup?
- For most residential systems, a single surveillance-grade drive is sufficient. RAID (mirrored drives for redundancy) is worth considering on commercial systems where footage loss would be a serious problem - warehouses, retail, and sites with compliance requirements. We advise based on your risk tolerance and budget.
