Product Overview
The NVS4E-NHD is a Reolink 4-channel PoE network video recorder that supports cameras with resolutions of up to 16MP, with hard drive capacity of up to 8TB (sold separately).
The specifications on this page are based on the **official product summary provided by the distributor**: Heatmap, data encryption, H.265+/H.265/H.264. The product page for this model has been removed from the Reolink official website (and no corresponding page is available from BASCO). The official summary does not list the dimensions, weight, power consumption or complete interface specifications, so we will not make assumptions.
The practical logic when choosing an NVR is not “the more channels, the better”, but whether three things match: whether the total power consumption of the cameras 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 at the entry-level to mid-range segment for 4 channels.

How many cameras can 4 channels support?
4 channels means that up to 4 cameras (or IP cameras) can be connected. In practice, we recommend keeping 1-2 channels in reserve for future expansion and to avoid putting too much strain on the total PoE power 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 the NVR is much simpler than installing a second unit.
- Keep 1-2 channels in reserve
- PoE power may be tight when all ports are occupied
- Choose more channels directly if you have significant expansion needs
What does support for up to 16MP mean?
The maximum supported input resolution determines whether this unit can support your cameras. Support for up to 16MP means that even high-end models can be recorded; if your camera exceeds this limit, it will have to record at a reduced resolution.
Please note: higher resolution means a higher bitrate, which also increases hard drive capacity requirements. For a 4K camera, 24-hour continuous recording uses approximately 70GB per day, while an 8TB hard drive can store approximately 110 days of footage (single camera); the retention period will be shortened proportionally when using multiple cameras.
- Determines whether high-end models are supported
- Higher resolution requires a larger hard drive
- Approximately 70GB per day for 4K
Hard Drive Capacity and Retention Period
Up to 8TB (sold separately). Hard drive capacity directly determines the retention period: capacity ÷ (daily data written × number of cameras).
Practical recommendation: For 2-4 cameras in a residential setting with event recording, 4TB is sufficient for one to two months; for shops with 24-hour continuous recording and 4 4K cameras, 8TB or more is recommended. When purchasing a hard drive separately, choose a surveillance-grade hard drive (supporting 24/7 writing). Standard desktop hard drives have a shorter lifespan under long-term continuous writing.
- Capacity ÷ Daily Data Written = Retention Period
- 4TB is sufficient for one to two months in a residential setting
- Please use a surveillance-grade hard drive
PoE Power Budget
The total power output of a PoE NVR is an absolute limit and is usually listed on the chassis or in the specifications. A standard fixed-lens camera typically uses approximately 8-12W, while PTZ cameras or models with built-in illuminators can use up to 20W. If you plan to connect multiple high-power cameras, you must calculate the total power consumption.
The official summary does not list the total PoE power output of this model, so we will not make assumptions. 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 power requirements.
- Total PoE power output is an absolute limit
- Fixed cameras use approximately 8-12W; PTZ cameras can use up to 20W
- Multiple high-power devices must be totaled
Compatibility with the Reolink App / ecosystem
Reolink NVRs can 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 a timeline 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
- Memory card provides buffering during network interruptions
Installation and Cooling
The NVR should be placed in a well-ventilated location (leave clearance when installed inside a cabinet), and avoid stacking it with heat sources such as routers and amplifiers. Noise from the hard drive during operation is normal; if continuous clicking sounds occur, 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 speculate; 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 immediately if the hard drive makes unusual noises
- Dimensions are subject to the manufacturer's specifications

Frequently Asked Questions
How many cameras can be connected?
4 channels; it is recommended to leave 1-2 channels spare.
Does the hard drive need to be purchased separately?
Up to 8TB (purchased separately); please confirm before purchase.
What resolutions are supported?
Up to 16MP input resolution.
Can a standard desktop hard drive be used?
Yes, but it is not recommended. Surveillance requires continuous 24/7 writing, so a dedicated surveillance hard drive should be used.
Can cameras from other brands be connected?
Models that support standard ONVIF may work, but features such as AI detection are most comprehensive when using cameras from the same manufacturer.
Does it provide PoE power?
Yes, 4-channel PoE.
Can it be viewed remotely?
Yes, via the Reolink App.
How many days of recording can be stored?
Capacity ÷ (daily data written × number of cameras). A single 4K camera uses approximately 70GB per day.
Does it support H.265?
It supports H.265 compression, which helps save hard drive space.
Warranty?
Hong Kong authorized stock, 2-year manufacturer warranty.
