Speco Technologies D4WVN8TB vs Speco Technologies D4WVN10TB: Specification Comparison
The Speco Technologies D4WVN8TB and D4WVN10TB are both 4-channel, 4K TVI wall-mount DVRs from the same product line, sharing identical chassis dimensions, compression standards, compliance certifications, and interface features. The sole differentiator is onboard storage capacity: 8TB versus 10TB. Buyers choosing between them are selecting a recording retention tier, not a different feature set or device class. This comparison documents every confirmed spec delta and flags where the specifications are identical, so integrators can make a storage-driven procurement decision with full transparency.

How does storage capacity differ, and what does that mean for recording retention?
The D4WVN8TB ships with 8TB of onboard hard drive storage. The D4WVN10TB ships with 10TB onboard — a 25% increase in raw capacity. Both units record across all 4 channels at 4K TVI resolution using H.265 or H.264 compression. Neither specification sheet states a frames-per-second rate, bitrate ceiling, or manufacturer-calculated retention estimate, so a precise retention delta cannot be derived from the provided data alone. At equal bitrates, the 2TB difference will proportionally extend continuous-record loops before overwrite. For high-retention mandates — retail loss prevention, regulated facilities, or sites with infrequent NVR access — the 10TB model provides that headroom without requiring an external expansion device. Neither model lists external storage expansion ports in the provided specs, so the installed drive represents the effective total capacity for each unit.
Are the physical build, environmental ratings, and power specifications identical across both models?
Yes — every physical and environmental specification provided is identical between the two models. Both measure 17.5 × 15.5 × 4.8 inches and weigh 8.0 lbs. Both carry an IP67 ingress protection rating and an IK10 impact resistance rating, making them suitable for installations in dusty, wet, or vandal-prone environments. Housing color is White on both. PoE+ (802.3at) is listed for both units, supporting powered camera connections directly from the DVR. Compression support — H.265 and H.264 — is identical. Audio capability (two-way with built-in mic) and ONVIF compatibility are listed for both. Neither spec sheet discloses operating temperature range, power consumption in watts, or maximum PoE budget, so those comparisons cannot be made from the available data.
Do both models carry the same compliance certifications and integration capabilities?
Both the D4WVN8TB and D4WVN10TB are listed as NDAA and TAA compliant, qualifying them for U.S. federal, state, and local government procurement under the National Defense Authorization Act and Trade Agreements Act requirements. Both support ONVIF, enabling interoperability with third-party 4K TVI and IP cameras that conform to the ONVIF standard. Both list analytics as a supported feature; however, neither spec sheet details which analytics functions are included (motion detection, line crossing, object classification, etc.), so integrators should consult the respective datasheets — linked as /content/product-datasheets/D4WVN8TB.pdf and /content/product-datasheets/D4WVN10TB.pdf — before committing to analytics-dependent deployments. Mount options listed for both include wall, ceiling, pole, pendant, corner, and rack, despite the wall-mount designation in the product name. Remote access software, VMS compatibility, and network port count are not specified.
Which should you choose: the D4WVN8TB or the D4WVN10TB?
Our take: The D4WVN10TB is the stronger choice when recording retention is the primary constraint and the installation budget can absorb the incremental cost of 2TB additional storage. Concretely: the D4WVN10TB provides 10TB versus the D4WVN8TB's 8TB — a 25% capacity increase — while every other confirmed specification is identical: same 17.5 × 15.5 × 4.8 in chassis, same 8.0 lb weight, same IP67/IK10 environmental ratings, same H.265/H.264 compression, same PoE+ (802.3at) support, same NDAA/TAA compliance, and the same 3-year warranty. The D4WVN8TB remains the appropriate selection for cost-sensitive deployments where 8TB satisfies the site's retention policy, or where storage is managed by scheduled overwrites on a short cycle. Both units serve the same 4-channel 4K TVI wall-mount use case; the decision is purely a storage-budget trade-off with no feature, compliance, or form-factor difference to weigh.

Frequently Asked Questions
Which should you choose: the D4WVN8TB or the D4WVN10TB?
The D4WVN10TB is the stronger choice when recording retention is the primary constraint and the installation budget can absorb the incremental cost of 2TB additional storage. Concretely: the D4WVN10TB provides 10TB versus the D4WVN8TB's 8TB — a 25% capacity increase — while every other confirmed specification is identical: same 17.5 × 15.5 × 4.8 in chassis, same 8.0 lb weight, same IP67/IK10 environmental ratings, same H.265/H.264 compression, same PoE+ (802.3at) support, same NDAA/TAA compliance, and the same 3-year warranty. The D4WVN8TB remains the appropriate selection for cost-sensitive deployments where 8TB satisfies the site's retention policy, or where storage is managed by scheduled overwrites on a short cycle. Both units serve the same 4-channel 4K TVI wall-mount use case; the decision is purely a storage-budget trade-off with no feature, compliance, or form-factor difference to weigh.
Is the D4WVN8TB or D4WVN10TB better for larger deployments?
Neither model expands beyond 4 channels — both are fixed 4-channel DVRs. For larger channel counts, a different product class is required. Within a 4-channel deployment, the D4WVN10TB's 10TB provides more continuous-record time than the D4WVN8TB's 8TB, making it the better fit when longer retention windows are needed at a single 4-camera location.
Can either DVR be used in a government or federal procurement project?
Yes. Both the D4WVN8TB and D4WVN10TB are listed as NDAA and TAA compliant in their specifications, qualifying them for federal, state, and local government purchases under standard procurement rules. No compliance difference exists between the two models.
Do the D4WVN8TB and D4WVN10TB support PoE cameras directly?
Both models list PoE+ (802.3at) in their specifications. However, the total PoE power budget — the maximum combined wattage available across all 4 ports — is not stated in the provided specifications for either model. Integrators powering high-draw cameras should verify the per-port and total PoE budget in the product datasheets before finalizing camera selection.
