Speco Technologies N64NR40TB vs Speco Technologies N64NR112TB: Specification Comparison
Both the N64NR40TB and N64NR112TB are Speco Technologies 64-channel, 4K H.265 NVRs in identical rack-mount white enclosures, targeting enterprise and large-venue IP camera deployments. The comparison centers on three decision axes: raw storage capacity and retention, warranty coverage, and analytics/resolution specifications. Buyers choosing between these two units are trading off upfront cost against long-term storage headroom and warranty protection, within an otherwise near-identical hardware platform.
In This Guide
How much storage and retention does each NVR provide?
The N64NR40TB ships with 40TB of integrated storage. Per the spec sheet, this supports 100+ days of recording at 4K resolution, depending on frame rate and scene complexity. H.265 compression is cited as reducing bandwidth and storage consumption by up to 50% versus H.264.
The N64NR112TB ships with 112TB of built-in storage — 2.8× the capacity of the N64NR40TB. The spec sheet states this eliminates the need for external storage arrays for extended retention schedules. H.265 is specified at 50%+ file-size reduction versus H.264. No explicit retention-day figure is published for the N64NR112TB in the provided specs.
For deployments requiring multi-month archives, high-density camera fields, or high frame-rate recording across all 64 channels, the 112TB unit provides substantially greater headroom without adding external NAS or DAS. The 40TB unit is sufficient where the 100+ day retention benchmark meets the site's compliance or review window requirements.
What warranty coverage and maximum resolution does each unit carry?
The N64NR40TB carries a 3-year warranty. Its maximum resolution is listed as 8MP (4K). The product name and spec fields consistently reference 4K / 8MP as the ceiling resolution across both channel count and recording.
The N64NR112TB carries a 2-year warranty — one year shorter than the N64NR40TB. Its resolution spec is listed as 16MP, which exceeds the 8MP figure on the N64NR40TB and suggests compatibility with higher-resolution camera sensors beyond standard 4K. The product title references 4K, but the resolution spec field states 16MP; buyers should confirm with Speco whether 16MP recording is supported or whether 16MP reflects camera input compatibility.
From a total-cost-of-ownership standpoint, the 3-year warranty on the N64NR40TB provides an additional year of covered parts and labor versus the N64NR112TB. Installers pricing multi-year service contracts should factor this difference into their bids.
How do the two NVRs compare on analytics, compatibility, and platform features?
Both units share identical feature parity across most integration and management dimensions per the provided specs: ONVIF-certified/compliant IP camera compatibility, H.265 and H.264 dual-compression support, audio input, PoE (802.3af) support, rack-mount form factor, People Counting analytics, and the EZ-Record, EZ-Copy, and EZ-Search feature set.
The N64NR112TB spec sheet adds the phrase 'Integrated event detection and object recognition' under analytics, and 'IP-based with multi-stream playback' under network architecture — neither of which appears explicitly in the N64NR40TB spec. The N64NR112TB also lists a frame rate of 30fps; no equivalent frame-rate figure is published for the N64NR40TB in the provided specs.
Both units share identical physical dimensions (21.7 × 6.1 × 21.0 in) and weight (17.86 lbs), and both are white rack-mount units. No port counts, bandwidth throughput figures, maximum IP camera megapixel ingestion rates, or software licensing terms are provided in the specs for either model.
Which should you choose: the N64NR40TB or the N64NR112TB?
Our take: The N64NR40TB is the stronger choice when warranty coverage and proven 4K retention benchmarks are the primary criteria, while the N64NR112TB is the stronger choice when raw storage capacity and potentially higher camera resolution are the deciding factors. Three concrete spec deltas: (1) Storage — 112TB vs 40TB, a 2.8× advantage for the N64NR112TB; (2) Warranty — 3 years vs 2 years, a one-year advantage for the N64NR40TB; (3) Resolution spec — 16MP vs 8MP on the N64NR112TB, though buyers should verify whether this reflects recording capability or camera input range. For 64-channel deployments with compliance-driven retention windows exceeding 100 days, or sites planning to deploy cameras above 4K, the N64NR112TB's storage advantage is material. For cost-sensitive or warranty-sensitive deployments where 40TB meets the retention requirement, the N64NR40TB's three-year coverage reduces service risk. Both units run the same Speco platform with identical ONVIF and EZ-feature support.

For cost-sensitive or warranty-sensitive deployments where 40TB meets the retention requirement, the N64NR40TB's three-year coverage reduces service risk. Both units run the same Speco platform with identical ONVIF and EZ-feature support.
Is the N64NR40TB or N64NR112TB better for longer video retention?
The N64NR112TB is better for longer retention. Its 112TB of built-in storage is 2.8× the 40TB on the N64NR40TB. The N64NR40TB spec sheet cites 100+ days at 4K; no equivalent day-count figure is published for the N64NR112TB, but its larger capacity directly translates to extended archives at equivalent frame rates and scene complexity.
Which NVR has the better warranty — the N64NR40TB or N64NR112TB?
The N64NR40TB has the longer warranty at 3 years versus 2 years for the N64NR112TB. That one-year difference is relevant when pricing multi-year service agreements or evaluating total cost of ownership over the product lifecycle.
Do the N64NR40TB and N64NR112TB support the same cameras and integrations?
Based on the provided specs, both units support ONVIF-compliant IP cameras, H.265 and H.264 compression, audio input, PoE (802.3af), and the Speco EZ-Record, EZ-Copy, and EZ-Search feature set. The N64NR112TB additionally references event detection and object recognition analytics and multi-stream playback in its spec sheet; these items are not explicitly listed for the N64NR40TB. Buyers should confirm full analytics feature parity with Speco directly.
