Technical Specifications

LTS LTD8504M-ST Platinum Turbo Smart DVR

The LTS LTD8504M-ST is a Platinum Turbo Smart DVR designed for users who want to keep existing analog cameras in service while adding smart analytics, flexible camera support, and modern remote access. With deep learning-based motion detection 2.0, perimeter protection, support for multiple analog video formats, and the ability to add up to 8 IP cameras, it gives smaller surveillance systems more room to grow without forcing a full replacement. This model fits well in homes, retail stores, offices, small commercial sites, and mixed analog-plus-IP upgrades where efficient playback, audio over coax, and flexible connectivity matter. If you need a DVR that helps bridge older coax systems with newer smart security features, this model is built for that job.

Ideal Applications

  • Upgrading older analog surveillance systems without replacing every camera
  • Small businesses and retail stores needing smart event filtering and efficient playback
  • Homes and offices using coax-based cameras with room to add IP channels later
  • Mixed analog and IP camera installations that need broad video input compatibility
  • Sites that benefit from audio over coax, smart search, and remote viewing through LTS Connect

These applications are based on the DVR’s 4 analog inputs, support for HDTVI, AHD, HDCVI, and CVBS sources, enhanced IP mode up to 8 channels, deep learning analytics, audio via coaxial cable, and network management features listed in the datasheet.

Common Uses

  • Recording up to 4 analog cameras while expanding with IP channels as needed
  • Reducing false alarms with human and vehicle classification on analog channels
  • Using line crossing and intrusion detection for perimeter monitoring
  • Reviewing footage faster with smart search and quick search by object or event type
  • Connecting to a Wi-Fi network through a USB Wi-Fi dongle
  • Managing remote viewing and network access through LTS Connect and DDNS
  • Using audio over coax to simplify audio support on compatible analog channels

These common uses come directly from the key features and specification sections across pages 1 to 3 of the PDF.
