The Hikvision iDS-9664NXI-M8/X is a 64-channel DeepinMind M Series network video recorder built for mid-to-large sites that need built-in deep-learning video analytics without relying entirely on edge-based camera intelligence. It supports up to 64 IP camera inputs, decoding resolutions from 32MP down to 1080p depending on channel load, and runs a dual-engine analytics package covering facial recognition, perimeter protection and video structuralization directly on the recorder itself. This makes it a strong fit for installers who want centralised AI processing that isn't limited to whichever individual cameras happen to support on-board analytics.
Hikvision iDS-9664NXI-M8/X 64-Channel DeepinMind NVR
Unlike simpler NVRs that depend on each connected camera to run its own analytics, the iDS-9664NXI-M8/X performs deep-learning video analysis centrally, on the recorder. It ships with two independent AI engines, each of which can be configured to run a different intelligent algorithm, giving installers flexibility to combine, for example, facial recognition on one engine with perimeter protection on the other, rather than being locked into a single analytics mode across the whole system. This is particularly useful on larger sites where different camera groups have different monitoring priorities — a car park entrance might need ANPR-style vehicle attention while a warehouse floor benefits more from perimeter and structuralization analytics.
Decoding capacity is tiered by resolution and channel count (up to 2 channels at 32MP, 2 at 24MP, 4 at 12MP, 8 at 8MP, 16 at 4MP, or 32 at 1080p), which lets the recorder handle a genuinely mixed camera estate rather than assuming every connected camera is the same resolution. Video is encoded in H.265+/H.265/H.264+/H.264, and up to 8 channels of IP speakers can be connected for site-wide audio alerts or warnings triggered by detected events.
Dual-Engine Deep-Learning Analytics
Two independent AI engines allow different intelligent algorithms to run simultaneously and independently across the camera estate. Supported analytics include facial recognition (face picture comparison, human face capture and face picture search across up to 32 face picture libraries, with capacity for up to 100,000 pictures in a list library, 10,000 in a stranger library and up to 10,000,000 in face capture), perimeter protection across up to 24 channels, and video structuralization (attribute extraction from faces, bodies and vehicles) across up to 12 channels.
Facial Recognition & AcuSearch
Face picture comparison from live camera streams runs at up to 48 channels combined (24 channels per engine), with a comparison speed of up to 48 pictures per second, supporting both list-based alarms (recognising known faces) and stranger alarms (flagging unrecognised faces against a watchlist). AcuSearch-style attribute search allows operators to retrieve footage by clothing colour, vehicle type and other structured attributes rather than scrubbing through raw video.
Network & Remote Access
Two self-adaptive 10M/100M/1000M Ethernet interfaces provide network connectivity, with Hik-Connect and DDNS support simplifying remote access setup. Smooth streaming technology helps maintain usable live view even over constrained network links, and the web interface is accessible without needing a browser plug-in.

Frequently Asked Questions
How many cameras can the iDS-9664NXI-M8/X support?
It supports up to 64 IP camera channels, with decoding capacity tiered by resolution — for example 2 channels at 32MP, 16 channels at 4MP, or 32 channels at 1080p — so the exact channel usage depends on the resolution mix across your camera estate.
What does "DeepinMind" mean for this NVR?
DeepinMind refers to Hikvision's deep-learning analytics platform running centrally on the recorder itself, rather than depending entirely on each connected camera's own on-board intelligence. This means facial recognition, perimeter protection and video structuralization can be applied consistently across the whole camera estate, including cameras that don't have advanced analytics built in.
Can it run two different types of analytics at once?
Yes, it has two independent AI engines that can each be configured to run a different intelligent algorithm, so for example one engine could handle facial recognition while the other runs perimeter protection, across different channel groups simultaneously.
How does the facial recognition feature work?
The recorder can compare faces captured from live camera streams against configured face libraries, supporting both "list" alarms (matching a known, enrolled face) and "stranger" alarms (flagging a face that isn't recognised). It supports up to 32 face libraries and very large storage capacity for captured face pictures.
What is video structuralization?
It's a feature that extracts descriptive attributes — such as clothing colour or vehicle type — from live video streams, making it possible to search recorded footage by those attributes rather than manually scrubbing through hours of video.
Does it support IP speakers for audio alerts?
Yes, up to 8 channels of IP speakers can be connected, which can be used to trigger audible warnings when the recorder's analytics detect a relevant event.
What resolutions can be recorded?
Camera resolutions from 1080p up to 32MP are supported, with the recorder's total decoding budget shared across channels depending on how many high-resolution cameras are connected at once.
How is remote access configured?
Through Hik-Connect and DDNS support, which simplify setting up remote viewing without needing extensive manual network configuration.
