LTS LTD8504M-ST 4-Channel Smart DVR with 8MP Support and H.265 Pro+

The LTD8504M-ST has 4 analog video input channels through BNC connections. The datasheet also says it supports IP camera expansion, starting with 2 IP channels and going up to 6, or up to 8 channels total when Enhanced IP mode is enabled. It supports IP cameras up to 8 MP resolution, with each enhanced IP channel supporting up to 4 Mbps. That gives buyers a flexible upgrade path if they want to keep analog cameras now and add IP cameras later.

Yes, the datasheet says deep learning-based motion detection 2.0 is enabled by default for all analog channels. It can classify humans and vehicles, which helps reduce false alarms caused by things like leaves, animals, and lights. The same section also says quick search by object or event type is supported, which can make playback review much faster. For buyers tired of constant nuisance alerts, this is one of the strongest features of this recorder. 

Yes, the key features section specifically lists deep learning-based perimeter protection. It also says the smart functions include line crossing and intrusion detection. In the detailed specifications, perimeter protection with human and vehicle analysis is supported on up to 4 channels. That makes the unit useful for users who want more than simple recording and need smarter event-based monitoring. 

This model supports multiple analog video formats, which is one of its main advantages for upgrade projects. The datasheet lists HDTVI, AHD, HDCVI, and CVBS input support, along with IP camera support using H.265+, H.265, H.264+, and H.264. That means it can work in mixed-camera environments where not every camera is the same type. For buyers replacing an older recorder, that flexibility can make the transition much easier.

Yes, the datasheet lists audio via coaxial cable as a key feature. In the specifications, audio input is shown as 1 RCA channel plus 4 channels via coaxial cable. It also includes 1 RCA audio output and 1-channel two-way audio using the audio input. That gives users more flexibility when audio is part of the surveillance setup.

The DVR supports video compression formats from H.264 up to H.265 Pro+, according to both the key features and the recording specifications. The datasheet also says H.265 Pro+ improves encoding efficiency and reduces data storage costs. For recording resolution, it supports up to 8 MP, with 8 MP at 8 fps available on channel 1 and 8 MP Lite at 15 fps on channels 2 through 4. That gives users a mix of higher resolution support and more efficient storage use.

The LTD8504M-ST includes 1 SATA interface for hard drive installation. The datasheet states it supports up to 10 TB storage capacity for each disk. Since this is a single-drive unit, buyers should plan their retention needs around one installed HDD. For many small systems, that still provides substantial recording capacity when paired with efficient H.265 Pro+ compression. 

Yes, the datasheet lists LTS Connect and DDNS for easy network management, which supports remote access use. It also says the unit can connect to a Wi-Fi network by using a Wi-Fi dongle through the USB interface. On the network side, it supports protocols including TCP/IP, PPPoE, DHCP, DNS, DDNS, NTP, SADP, NFS, iSCSI, UPnP, HTTPS, and ONVIF. That gives buyers several options for network integration and remote connectivity.

The recorder provides both HDMI and VGA outputs, and the datasheet says they can operate simultaneously. HDMI output supports up to 2K at 2560 × 1440 at 60 Hz, while VGA supports up to 1920 × 1080 at 60 Hz. The unit also supports 4-channel synchronous playback and smart search for efficient playback. That combination helps users review footage locally with better flexibility and less wasted time.

Yes, the datasheet includes two important notes. First, motion detection 2.0 and perimeter protection cannot be enabled at the same time, so enabling one makes the other unavailable. Second, Enhanced IP mode may conflict with smart events such as face picture comparison, motion detection 2.0, and perimeter protection, and the datasheet says to refer to the user manual for details. Those notes are important because they affect how you plan features in mixed analog and IP setups.
