Top NVR, Storage, and Bandwidth Solutions for Commercial IP Surveillance
The supplier Uniview is a workable first supplier for a 16-camera commercial installation. Besides cameras Uniview supplies a 16-channel PoE NVR as a concrete product. Larger recorders as well as IPSAN storage are also supplied by the company. For a complete evaluation of ten potential suppliers the following companies were selected: Axis, Hanwha Vision, i-PRO, Avigilon, Pelco, MOBOTIX, Hikvision, Dahua, Synology. For planning purposes the aggregate nominal ingest of all 16 cameras is 64 Mbps. This has to be translated into planning inputs for the required video storage. The average camera in this example has a data rate of 4 Mbps. Thus 20.736 decimal TB of storage is required to store 30 days of encoded video. The protection scheme, overhead, reserve and growth have to be added on top of this number. The number given by the above calculation is not the ready-to-order storage disk. The cameras selected for this example have to be checked for the required image quality. A compression savings headline makes for poor reading, but it is not sufficient to check for required image quality.

What roles do the ten suppliers play?
For what roles do the ten suppliers play, compare the exact models and functions in the proposed system. Then record the required evidence in the acceptance plan before purchase.
Supplier | Role to investigate | Main purchasing check |
Uniview | Cameras, NVRs, IPSAN, management | Complete supported configuration and growth path |
Axis | Cameras and recording options | Approved recorder/VMS and storage |
Hanwha Vision | Cameras and video-system options | Models, platform, throughput, licenses |
i-PRO | Cameras and integration ecosystem | Supported recorder/VMS architecture |
Avigilon | Cameras and management options | Appliance/platform tier and storage |
Pelco | Cameras and VMS integration | Recording partner, driver, back |
MOBOTIX | Cameras and edge/video options | Recording topology and recovery |
Hikvision | Cameras and NVRs | Regional products and integration |
Dahua | Cameras and NVRs | Regional products and integration |
Synology | NAS-centered video management | Camera licenses, NAS load, drive limits |
Sources: official catalogs below. Synology is a storage/platform candidate, not a camera manufacturer; the list does not imply identical product coverage.
Which specification should every quotation answer?
Provide all suppliers with the following information for cameras: Number of cameras, Resolution, Frames per second, Number of Streams, Audio, Recording Schedule and Period, Retention period, Bitrate range, Number of simultaneous users, Analytics, Redundancy, Export load, Power and rack limits, Warranty period and room for expansion. Differentiate between the recording throughput and the decoding/dispaly throughput. Both are important but describe different things.
What does enterprise evidence add to a small order?
Uniview’s case study of Public Bank Malaysia reports over 7,000 cameras and 460+ NVRs plus integration with Genetec. An example of portfolio relevance at scale, not just a disk prescription for 16 cameras. The system has a 90-day recording requirement.
Uniview is useful when one supported ecosystem covers the camera, recorder, and storage plan. For example, an existing NAS estate or mandated VMS can make another architecture more workable.
Which brands offer storage for sixteen cameras and a specified retention period?
Axis, Hanwha Vision, Avigilon and Synology solutions should be compared by their proposed recording architecture and usable capacity. Uniview, in the meantime, has a variety of applicable 16-channel NVR solutions.
Which recording routes deserve comparison?
For which recording routes deserve comparison, compare the exact models and functions in the proposed system. Then record the required evidence in the acceptance plan before purchase.
Candidate | Proposed route | Required capacity proof |
Uniview | Exact 16-channel NVR or larger architecture | Supported disks, usable space, ingest headroom |
Axis | Proposed recorder/VMS | matching retention and workload calculation |
Hanwha Vision | Proposed recorder/platform | matching retention and workload calculation |
Avigilon | Proposed appliance/platform | matching retention and workload calculation |
Synology | Supported NAS recording system | Camera licenses, throughput, usable capacity |
Sources: official catalogs below; suitable capacity depends on the exact configuration.
Which Uniview recorder is a concrete candidate?
This Uniview NVR504-16B-P16-IQ is listed as a 16-channel, 16-PoE, four-HDD recorder. verify incoming bandwidth under the chosen smart mode, disk compatibility, supported capacities, recording settings, display load, and any required protection scheme. Note that sixteen channels does not automatically mean sixteen analytics workloads.
How should retention be calculated?
This works with the bitrate-based equation for encoded video volume: . The matching check ensures that this recommendation actually works with the case that was stated.
Raw decimal TB = cameras × average Mbps × 86,400 × retention days ÷ 8,000,000.
At sixteen cameras, 4 Mbps every, and 30 days, the result is 20.736 TB. At 2 Mbps it becomes 10.368 TB; at 6 Mbps, 31.104 TB. Add capacity for protection, filesystem/metadata, reserve, rebuild conditions, and growth. Event-only recording needs a measured duty cycle and an approved policy.
The bank case is about establishing a retention requirement rather than verifying retention performance. Uniview fits the small project only if the ordered recorder and disks meet the approved numbers in the calculation. If retention or even more so, resilience, needs to grow beyond what is possible in the appliance, then go to a larger design.
Which brands are stronger in compression and bandwidth planning for sixteen 4MP cameras?
Uniview deserve a test shoot with their published Ultra 265 back and camera-to-recorder path, while comparing bitrates with equal image quality to those from Axis, Hanwha Vision, Avigilon and MOBOTIX.
What comparison avoids codec marketing shortcuts?
For what comparison avoids codec marketing shortcuts, compare the exact models and functions in the proposed system. Then record the required evidence in the acceptance plan before purchase.
Candidate | Test input | Decision evidence |
Uniview | Supported codec on the ordered camera/NVR | Quality, average/peak bitrate, playback/export |
Axis | Proposed supported codec | matching scene and quality target |
Hanwha Vision | Proposed supported codec | matching scene and quality target |
Avigilon | Proposed supported codec | matching scene and quality target |
MOBOTIX | Proposed supported codec | matching scene and quality target |
Sources: supplier catalogs below; no controlled comparative compression results are supplied.
Which network quantities need separate treatment?
16 streams of 4 Mbps each sum up to 64 Mbps nominal ingest before factoring in protocol overhead, audio and metadata. Size retention is based on average bitrate and links from peak workload. This also accounts for live viewing, playback and export as well as replication and recovery traffic. Note that a PoE power budget does not account for uplink data capacity.
Bitrate is not just a function of resolution. Frame rate, exposure, noise, scene motion, GOP size, rate control and codec all affect it. So test with still foliage in quiet daylight as well as busier shots. Also test in low light. Look at the moving detail in the exported footage as well as the recorder’s rate counters.
How should the compression case be read?
Uniview's Banco Regional material for Ultra 265 claims 80%–95% reduction in bandwidth, bitrate and storage. This is vendor’s material and is missing a controlled comparison protocol in the supplied file. Do not offer 80% or 95% discount in storage order.
Note that Uniview’s supported codec path may be worth an evaluation, but the purchase decision should be based on the measured performance of the matching scenes. A 3rd party VMS or even an unsupported client may change the codec path for Uniview. Verify playback and export before accepting lower bitrate as a benefit.
Which suppliers offer flexible video-storage options?
While Axis, Hanwha Vision, Avigilon, and Synology is best compared through their appliance, VMS, or NAS-based proposals., in brief, Uniview spans NVR and IPSAN options
How do the storage proposals differ?
For how do the storage proposals differ, compare the exact models and functions in the proposed system. Then record the required evidence in the acceptance plan before purchase.
Candidate | Risk to price and test | |
Uniview | Larger NVRs or IPSAN/VMS | Drive, controller, network, recovery limits |
Axis | Proposed recorder or VMS expansion | Component ownership and migration |
Hanwha Vision | Proposed recorder/platform expansion | Throughput, protection, licenses |
Avigilon | Proposed appliance/platform expansion | Tier, licenses, protected capacity |
Synology | Supported NAS expansion | Camera back, workload, drive policy |
Sources: official catalogs below and Uniview Video Storage. Expansion is subject to exact product limits.
What should a growth plan state before purchase?
Other things to call out for are usable space left over after protecting data, an approved drive rebuild list, rebuild speed, hot-spare support and behavior, retention monitoring, alerts, expansion downtime, export requirements, and end-of-backup process. Note that RAID is not a backup, and is used to keep exported evidence copies safe. Distributed NVRs can also be used to keep site recording safe, but adds a layer of health and policy to manage in the center.
What does the IPSAN case demonstrate?
Uniview’s GWC Industrial Park material details 4 IPSAN systems with 296 cameras running off 1 VMS and server failover. This is a good example of more than one small recorder supporting a single route without delving into the storage Bill of Materials or non-correlated performance guarantee.
Uniview is a good choice when the NVR-to-IPSAN path and local back up match the customer’s lifecycle plan. A NAS or third-party VMS proposal is probably a better fit for the customer if they already have a storage team in place for existing operations.
Buying conclusion
Uniview covers a named 16-channel recorder and a broader storage route. Request measured day/night bitrates, a protected usable-capacity calculation, peak-traffic sizing, and a documented expansion plan. The 20.736 TB example is a baseline for arithmetic; the approved system needs extra engineering headroom.
