Speco D4VN4TB 4 Channel 4K Tvi Dvr 4TB Taa

Product Description

The SPECO D4VN4TB is a 4-channel digital video recorder engineered for 4K TVI (Turbo High Definition Video Interface) surveillance systems. It ships with 4TB of onboard storage, giving installers immediate recording capacity without a separate drive purchase. Designed for security professionals, this DVR handles high-resolution analog camera feeds and serves as the central recording and management hub in TVI-based CCTV installations. TAA compliance makes it eligible for government and federal procurement contracts where Trade Agreements Act conformance is required.

This unit is suited for small to mid-size commercial and institutional installations where 4K TVI cameras are already deployed or planned. Typical applications include retail, light commercial, and government facility surveillance. Security integrators and low-voltage technicians are the primary installers. The 4TB internal storage supports extended continuous or motion-triggered recording retention at high resolution, reducing the need for frequent drive swaps in active monitoring environments.

Installation Notes

Installation should be performed by a licensed low-voltage or security systems technician in accordance with local codes and NEC Article 725 guidelines for low-voltage wiring. Power down all connected cameras and disconnect the recorder from mains power before servicing internal components or drives. Ensure adequate ventilation around the unit to prevent thermal buildup during continuous operation. Verify camera signal format compatibility before connecting TVI camera feeds to avoid signal mismatch.
