Speco Technologies N64NR24TB vs Speco Technologies N64NR112TB: Specification Comparison
Both the Speco Technologies N64NR24TB and N64NR112TB are 64-channel 4K H.265 network video recorders aimed at enterprise and multi-site physical security deployments. They share the same chassis dimensions, compression standard, channel capacity, and ONVIF compatibility, making them direct cross-shop candidates. The primary differentiator is internal storage capacity — 24TB versus 112TB — which drives retention duration, scalability planning, and total cost of ownership decisions for installers and IT procurement teams.

How much internal storage does each NVR provide, and what does that mean for retention planning?
The N64NR24TB ships with 24TB of internal storage, while the N64NR112TB ships with 112TB — a 4.67× difference in raw capacity. Both units record 64 IP cameras at 4K resolution using H.265 compression, which the N64NR112TB spec sheet quantifies as delivering 50%+ file size reduction versus H.264; the N64NR24TB spec sheet similarly states up to 50% savings.
At identical camera counts, resolution, and compression settings, retention duration scales nearly linearly with storage. A deployment that achieves 7–10 days of retention on the N64NR24TB would approach 32–47 days on the N64NR112TB under equivalent load — though actual figures depend on scene complexity, frame rate, and stream configuration not fully detailed in either spec sheet.
The N64NR112TB spec sheet specifically states the 112TB capacity 'eliminates external arrays for extended retention schedules,' positioning it for regulated environments (healthcare, finance, gaming, critical infrastructure) where 30-day or longer retention is mandated. The N64NR24TB is sized for shorter-cycle deployments or sites where external NAS/SAN expansion is planned.
Are there differences in recording resolution, frame rate, or compression capability between the two units?
Both NVRs support 64 IP camera channels and record at 4K Ultra HD resolution using H.265 as the primary codec, with H.264 also listed as supported on both. The N64NR24TB spec sheet cites 8MP as its resolution figure; the N64NR112TB spec sheet lists 16MP — a meaningful discrepancy worth clarifying with Speco, as 4K UHD corresponds to approximately 8MP (3840×2160), and 16MP suggests a higher-resolution ceiling that may reflect maximum supported camera resolution rather than NVR output resolution.
The N64NR112TB spec sheet explicitly states a 30fps frame rate. The N64NR24TB spec sheet does not list a frame rate value — buyers requiring a confirmed frame rate specification for the 24TB model should consult the datasheet at /content/product-datasheets/N64NR24TB.pdf.
Both units list multi-stream playback capability (explicitly noted on the N64NR112TB), EZ-Record, EZ-Copy, and EZ-Search features, PoE (802.3af) support, audio input, and People Counting analytics. No throughput (Mbps) or simultaneous playback channel count is specified for either model in the provided data.
How do the two NVRs compare on camera compatibility, analytics depth, and physical installation requirements?
Both the N64NR24TB and N64NR112TB are ONVIF-compliant, supporting third-party IP cameras alongside Speco's native line. Both include People Counting as a listed analytics feature. The N64NR24TB spec sheet additionally itemizes object detection, motion analysis, and event alerts as analytics capabilities; the N64NR112TB spec sheet describes 'integrated event detection and object recognition' — functionally similar language, though the N64NR24TB provides more explicit analytics taxonomy in the provided data.
Physical build is identical across both models: dimensions are 21.7 × 6.1 × 21.0 inches, weight is 17.86 lbs, housing color is white, and both are rack-mount form factor. Neither unit lists operating temperature range, humidity tolerance, or power consumption (watts/BTU) in the provided specifications — integrators should verify environmental and power requirements from the respective datasheets before rack planning.
Warranty coverage differs: the N64NR24TB carries a 3-year warranty versus a 2-year warranty on the N64NR112TB. The N64NR112TB spec sheet also lists a 'Fisheye' type designation, which appears inconsistent with an NVR product and may be a data entry artifact — buyers should confirm with Speco before specifying. Both units share the same accessory bundle IDs (21279, 21287, 7004, 21286), indicating compatible peripheral ecosystems.
Which should you choose: the N64NR24TB or the N64NR112TB?
Our take: The N64NR112TB is the stronger choice when long-term on-site retention is the primary requirement — its 112TB internal capacity delivers approximately 4.67× more storage than the N64NR24TB's 24TB, enabling extended retention without external storage arrays on the same 64-channel, 4K H.265 recording platform. Additionally, the N64NR112TB specifies a confirmed 30fps frame rate and a 16MP maximum resolution ceiling, neither of which is documented for the N64NR24TB in available spec data. Conversely, the N64NR24TB holds a 3-year warranty versus the N64NR112TB's 2-year coverage — a meaningful difference for lifecycle cost planning. Choose the N64NR24TB for deployments with shorter retention mandates, tighter upfront budgets, or where a longer warranty term is contractually required; choose the N64NR112TB for high-channel-density sites with 30-day-plus retention requirements or regulated industries where eliminating external storage arrays reduces audit complexity.

Frequently Asked Questions
Which should you choose: the N64NR24TB or the N64NR112TB?
The N64NR112TB is the stronger choice when long-term on-site retention is the primary requirement — its 112TB internal capacity delivers approximately 4.67× more storage than the N64NR24TB's 24TB, enabling extended retention without external storage arrays on the same 64-channel, 4K H.265 recording platform. Additionally, the N64NR112TB specifies a confirmed 30fps frame rate and a 16MP maximum resolution ceiling, neither of which is documented for the N64NR24TB in available spec data. Conversely, the N64NR24TB holds a 3-year warranty versus the N64NR112TB's 2-year coverage — a meaningful difference for lifecycle cost planning. Choose the N64NR24TB for deployments with shorter retention mandates, tighter upfront budgets, or where a longer warranty term is contractually required; choose the N64NR112TB for high-channel-density sites with 30-day-plus retention requirements or regulated industries where eliminating external storage arrays reduces audit complexity.
Is the N64NR24TB or N64NR112TB better for larger deployments with long retention requirements?
The N64NR112TB is the purpose-built choice for long retention. Its 112TB internal storage — versus 24TB on the N64NR24TB — provides roughly 4.67× more capacity on the same 64-channel, 4K H.265 platform, making it suitable for regulated environments requiring 30 days or more of footage without external storage arrays. Both units record the same number of channels at the same resolution, so the decision hinges on how many days of footage must be retained on-box.
Do both NVRs support third-party IP cameras, or are they locked to Speco cameras?
Both the N64NR24TB and N64NR112TB are ONVIF-compliant, meaning they are compatible with third-party ONVIF IP cameras in addition to Speco's native product line. Both also list People Counting analytics and share the same EZ-Record, EZ-Copy, and EZ-Search feature set, so camera ecosystem flexibility is equivalent across the two models.
Which model has the better warranty, and does it matter for a commercial installation?
The N64NR24TB carries a 3-year warranty compared to the N64NR112TB's 2-year warranty. For commercial installations — particularly those with multi-year service contracts, maintenance agreements, or facilities where NVR downtime has operational or compliance consequences — the extra year of coverage on the N64NR24TB may reduce lifecycle support costs. Buyers specifying the N64NR112TB for its storage capacity should factor in the shorter warranty when budgeting for extended support.
