The Viking Electronics TDF-HRT is the companion software for the Viking Electronics TDR-1 handset recording system, sold together as a matched set. If you are deploying the TDR-1 in a commercial or institutional environment — lobbies, elevator cabs, stairwells, or security stations — the TDF-HRT software is the required configuration and management interface for that hardware. It is not sold or licensed separately from the TDR-1 unit.
The TDF-HRT software enables setup, configuration, and management of the TDR-1 emergency phone and intercom hardware. Viking bundles this software with the TDR-1 specifically so the hardware arrives deployment-ready: installers do not need to source a separate license or download a standalone installer from a third party. This keeps commissioning straightforward on projects where the TDR-1 is integrated into a broader intercom or access control system.
Viking Electronics designs and manufactures communication and security systems for commercial installations. The TDR-1 platform — and by extension the TDF-HRT software — is intended for facilities requiring reliable, managed handset recording: think healthcare corridors, institutional stairwells, or elevator cab emergency phones where call-recording compliance matters. Confirm with your project specifications that the TDR-1 hardware itself meets your environmental and mounting requirements before specifying this SKU, since TDF-HRT is only meaningful in that paired context.
For projects that need a broader look at Viking Electronics communication products, the full Viking line covers everything from standard analog phone panels to vandal-resistant marine-grade enclosures suitable for exterior and elevator installations.
Q: Is the TDF-HRT sold separately from the TDR-1?
A: No. The TDF-HRT software is sold with the TDR-1 handset recording system as a bundled package. It is not available as a standalone software license.
Q: What does the TDF-HRT software do?
A: The TDF-HRT is the configuration and management software for Viking's TDR-1 handset recording system, enabling setup and operation of the hardware in commercial and institutional installations.
Q: What type of installations is the TDR-1 / TDF-HRT suited for?
A: The TDR-1 with TDF-HRT software is suited for commercial environments requiring managed handset recording — including healthcare facilities, institutional buildings, elevator cabs, and security stations where call-recording compliance is a project requirement.
Q: Who manufactures the TDF-HRT?
A: Viking Electronics, a US-based manufacturer of security and communication systems located in Hudson, Wisconsin, designs and manufactures the TDF-HRT and TDR-1.

The TDF-HRT is one of those SKUs that trips up procurement when it appears as a line item without context. It is not a standalone product — it is the software component of Viking's TDR-1 handset recording system, always sold as a bundle. If you are seeing TDF-HRT on a quote or specification sheet, you are looking at a TDR-1 deployment with the configuration software included, which is exactly how Viking intends it to be used.
Technical Highlights:
Deployment Considerations:
Best suited for healthcare corridors, institutional elevator cabs, or security station deployments where Viking's TDR-1 handset recorder has already been specified and the software component needs a distinct line-item SKU for procurement tracking.
