Choose the LTD8424K-EA for 24 analog video inputs or the LTD8432K-EA for 32. Instead of trying to piece together several small recorders as your camera count grows, you can centralize a much larger surveillance system in one DVR.

The DVR supports HDTVI, AHD, HDCVI, CVBS, and IP video inputs. If you're upgrading an existing coax system, that flexibility can help you transition camera technologies without automatically requiring a complete replacement of every camera at once.

The LTD8424K-EA supports IP expansion up to 40 channels, while the LTD8432K-EA supports up to 48 channels. Compatible IP cameras can be used at resolutions up to 6 MP, giving you another path for expanding beyond the DVR's physical analog inputs.

H.265 Pro+ is designed to improve encoding efficiency and reduce data storage cost. When you're recording dozens of cameras, better compression can make a meaningful difference in how efficiently available hard-drive space is used.

Four SATA interfaces support hard drives up to 10 TB each, providing substantial internal recording capacity. The DVR also supports eSATA, giving installations that require additional storage another expansion option.

Recording video is only useful if you can efficiently locate the footage you need. Smart search helps streamline playback, while the recorder supports synchronous playback of up to 16 channels for reviewing activity across multiple cameras.

The DVR supports multiple VCA events for analog and compatible smart IP cameras, including up to 4-channel line crossing detection, 4-channel intrusion detection, and 1-channel sudden scene change detection.

That gives you more than continuous recording alone by allowing supported cameras and channels to respond to specific types of activity.

HDTVI signals can travel up to 800 meters at 1080p or up to 1200 meters at 720p. That makes the platform particularly useful when cameras need to be positioned far from the recorder.

The HDMI2 output supports up to 3840 × 2160 resolution at 30 Hz, while additional HDMI1/VGA connectivity gives you flexible options for connecting surveillance monitors.

The DVR supports LTS-Connect, DDNS, and up to 128 remote connections, along with a Gigabit Ethernet interface. This gives supported installations network-based management capabilities without requiring someone to remain physically in front of the recorder for every interaction.

For retail and point-of-sale environments, the DVR supports POS-triggered recording and POS information overlay. This can make recorded surveillance more useful when reviewing activity associated with transactions.

The recorder supports third-party cloud storage through Dropbox, Google Drive, and Microsoft OneDrive, giving compatible deployments another option for handling selected stored data.

With 16 alarm inputs, 4 alarm outputs, four RCA audio inputs, one audio output, and an independent two-way audio connection, the recorder can form part of a more comprehensive surveillance installation instead of functioning as video storage alone.
