LTS Platinum LTD8504D-ST-AU 4-Channel HD-TVI Hybrid DVR

The LTS Platinum LTD8504D-ST-AU is a 1U hybrid digital video recorder built for small to mid-sized surveillance installations that need clear 4K-capable footage without the cost of a full IP system. It combines 4 analog channels supporting five signal types (HD-TVI, AHD, HD-CVI, CVBS and IP) with 4 additional IP inputs, expandable to 8 IP channels, giving installers flexibility to mix existing analog cameras with newer network cameras on the same recorder. Deep-learning based analytics, H.265 Pro+ compression and a fast Direct Search function make this barebone DVR a practical, budget-friendly core for retail, office, warehouse and residential CCTV upgrades.

• High-Resolution Recording: Encodes at 4K/8MP at 8fps or 3K/5MP at 12fps using efficient H.265 Pro+ compression to save storage space.
