Reolink NVS16-NHD 16-Channel PoE Network Video Recorder (NVR) | Up to 12MP

16 channels｜Up to 12MP input｜2×SATA, up to 12TB (6TB each)｜24/7 continuous recording, 16 PoE ports

Product Overview

The NVS16-NHD is Reolink's 16-channel PoE network video recorder, supporting cameras with resolutions of up to 12MP, with 2×SATA hard drive bays and support for up to 12TB (6TB each).

The specifications on this page are based on the **official product summary provided by the distributor**: 24/7 continuous recording and 16 PoE ports. The model page has been removed from the Reolink official website (and BASCO has no corresponding page either). The official summary does not list the dimensions, weight, power consumption, or a complete interface list, so we will not speculate.

The practical logic when choosing an NVR is not “the more channels, the better”, but whether three things match up: whether the total camera power consumption is within the PoE budget, whether the hard drive capacity is sufficient for the number of days of footage you want to retain, and whether the maximum supported resolution is compatible with your cameras. This model is positioned as an entry-level to mid-range option in the 16-channel category.

Six Key Highlights

How many cameras can 16 channels support?

16 channels means that up to 16 cameras (or IP cameras) can be connected. In practice, we recommend leaving 1-2 channels available for future expansion and to avoid putting too much strain on the total PoE power budget when all ports are occupied.

If you currently have 3 cameras and plan to add 1 more, 4 channels is just right. If you expect to expand to 6 or more cameras, choosing an 8-channel or 16-channel model directly will be more convenient — replacing an NVR is much simpler than installing a second one.

• Leave 1-2 channels available
• The PoE power budget may become tight when all ports are occupied
• Choose more channels directly if you expect significant expansion

What does support for up to 12MP mean?

The maximum input resolution determines whether this unit can support your cameras. Support for 12MP input means that even high-end models can be recorded; if your cameras exceed this limit, they will have to record at a reduced resolution.

Please note: higher resolution means a higher bitrate, which also increases hard drive capacity requirements. Taking a 4K camera as an example, 24-hour continuous recording uses approximately 70GB per day, while an 8TB hard drive can store around 110 days of footage (for one camera); with multiple cameras, the retention period is shortened proportionally.

• Determines whether high-end models are supported
• Higher resolution requires a larger hard drive
• 4K uses approximately 70GB per day

Hard Drive and Retention Days

2×SATA, up to 12TB (6TB each). Hard drive capacity directly determines the retention period: Capacity ÷ (daily data written × number of cameras).

Practical recommendation: For homes with 2-4 cameras using event recording, 4TB is sufficient for one to two months. For shops using 24-hour continuous recording with 4 4K cameras, 8TB or more is recommended. When purchasing a hard drive separately, choose a surveillance-grade hard drive that supports 24/7 writing. Standard desktop hard drives have a shorter lifespan under long-term continuous writing.

• Capacity ÷ daily data written = retention days
• 4TB is sufficient for one to two months in a home
• Use a surveillance-grade hard drive

PoE Power Budget

The total power output of a PoE NVR is an absolute upper limit, usually indicated on the unit or in the specifications. Standard fixed-lens cameras typically use around 8-12W, while PTZ or models with built-in illuminators can consume up to 20W. If you plan to connect multiple high-power cameras, you must calculate their total power consumption.

The official summary does not list the total PoE power output of this model, so we will not speculate. If you need the exact figure before placing an order, please contact us, or provide the models you plan to connect and we can help estimate the requirements.

• Total PoE power output is an absolute upper limit
• Fixed cameras use approximately 8-12W; PTZ cameras can use up to 20W
• The total power consumption of multiple high-power devices must be calculated together

Compatibility with the Reolink App / ecosystem

Reolink NVRs work with cameras, doorbells, and Home Hub products from the same brand, all managed through a single app. Recording can be set to continuous, scheduled, or event-triggered; playback supports timeline viewing and event filtering.

If you use both a memory card and an NVR: the card serves as a buffer during network interruptions, while the NVR provides long-term centralized storage. Using both together is the most reliable option.

• Manage the entire product range in one app
• Supports event-filtered playback
• Use a memory card as a buffer during network interruptions

Installation and heat dissipation

The NVR should be placed in a well-ventilated location (leave clearance when installed inside a cabinet), and should not be stacked with heat sources such as routers or amplifiers. Noise from the hard drive during operation is normal; if continuous clicking occurs, back up your data immediately and check the hard drive.

The official summary does not list the dimensions or power consumption, so we will not estimate them; refer to the manufacturer's specifications for the actual device dimensions.

• Place in a well-ventilated location and avoid stacking with heat sources
• Back up data immediately if the hard drive makes unusual noises
• Dimensions are subject to the manufacturer's specifications
