The DS-7604NXI-K1/4P supports up to 4 IP camera inputs, which makes it a practical fit for smaller systems that need focused coverage without overcomplicating setup. It also includes 4 independent PoE network interfaces, so you can connect compatible cameras directly to the recorder for plug-and-play installation. That matters because it can reduce extra wiring steps and help keep the installation cleaner. The datasheet also lists up to 40 Mbps incoming bandwidth, which is an important limit to consider when choosing camera resolutions and bitrates.

Yes, this model supports HDMI output at up to 4K resolution, specifically 3840 × 2160 at 30 Hz. The datasheet also shows recording resolution support up to 12 MP, which gives you flexibility for higher-resolution compatible IP cameras. For decoding, the recorder can handle different performance levels depending on whether AI is on or off, so your live view and playback capacity will depend on the stream settings you use. In practical terms, that means it is capable of high-resolution monitoring, but the overall system design should still stay within its listed decoding and bandwidth limits.

Yes, it has 4 built-in PoE ports, listed as 4 RJ-45 10/100 Mbps self-adaptive Ethernet interfaces. The PoE standard is IEEE 802.3af/at, and the datasheet lists PoE power at up to 50 W. This is helpful because it allows the recorder to supply power and network connectivity through a single cable to compatible cameras. For many buyers, that means less installation hassle and fewer separate power accessories to manage.

This NVR includes Hikvision AcuSense technology, and the datasheet states that all channels support Motion Detection 2.0. It also supports human and vehicle analysis on 4 channels, which is useful when you want more relevant event filtering instead of reviewing every movement clip manually. In addition, the datasheet lists smart search for a selected area in the video and smart playback to improve playback efficiency. That can save time when you need to find meaningful footage faster.

Yes, the datasheet lists facial recognition functions on this model. It supports 1-channel facial recognition for video stream, or 2-channel facial recognition for face picture comparison alarms. The recorder also supports face picture comparison, human face capture, and face picture search, along with up to 16 face picture libraries and up to 20,000 face pictures in total within the stated limits. One important note from the datasheet is that facial recognition and Motion Detection 2.0 cannot be enabled at the same time.

The DS-7604NXI-K1/4P has 1 SATA interface for HDD connection. According to the datasheet, it supports up to 10 TB capacity for each hard drive. It also uses H.265+ compression, which the datasheet says can reduce storage space by up to 75%, helping you retain footage longer depending on your settings. That is especially useful when you want to balance image quality and storage efficiency in a compact NVR.

Yes, the datasheet specifically lists Hik-Connect for easy network management. It also shows support for common network protocols including TCP/IP, DHCP, IPv4, IPv6, DNS, DDNS, NTP, RTSP, HTTP, and HTTPS, along with one self-adaptive 10/100/1000 Mbps Ethernet interface. The recorder supports up to 128 remote connections, which can be useful in multi-user environments. In everyday use, that means it is designed to integrate into standard networked surveillance setups with remote access capability.

Yes, the datasheet lists 1-channel audio output through RCA and 1-channel two-way audio using the audio input. It also supports multiple audio compression formats, including G.711ulaw, G.711alaw, G.722, G.726, and AAC. This matters if your setup includes cameras or applications where listening back or speaking through the system is important. It gives the recorder more flexibility than a video-only unit when audio support is part of the installation plan.

This model provides simultaneous HDMI and VGA outputs. The HDMI output supports up to 4K resolution, while the VGA output supports up to 1920 × 1080 at 60 Hz. That is useful if you want the flexibility to connect either a modern 4K display or a standard monitor depending on the installation environment. The datasheet also states the video output mode is HDMI1/VGA simultaneous output, which can make local monitoring more convenient.

The datasheet lists the dimensions as 320 mm × 240 mm × 48 mm, which is about 12.6 × 9.4 × 1.9 inches. Power supply is listed as 48 VDC, 1.35 A, and the unit’s consumption is ≤ 10 W without HDD and with PoE off. The listed weight is ≤ 1 kg without HDD, or about 2.2 lb. For buyers planning a shelf, cabinet, or wall-adjacent installation area, those details help confirm space and power needs before purchase.
