Manufacturer details describe the cited version. Confirm the exact unit and intended system.

Recording, display and audio

Device class: Network Video Recorder
IP camera inputs: 64 IP camera input channels. This count is separate from simultaneous decoding and playback limits.
Incoming bandwidth: 400 Mbps incoming-bandwidth reference. Camera stream rates and channel limits still apply.
Outgoing bandwidth: 400 Mbps outgoing-bandwidth reference; not the available internet connection speed.
Display connections: Two HDMI and two VGA interfaces. Their supported resolutions and output pairings are separate from the camera-input count.
HDMI 1 display modes: HDMI 1 lists 7680 × 4320 at 30 Hz, 3840 × 2160 at 60 or 30 Hz, and lower display modes. This is display output, not an all-camera recording or decoding rate.
HDMI 2 display modes: HDMI 2 lists 3840 × 2160 at 60 or 30 Hz and lower modes. Confirm simultaneous output settings before selecting displays.
VGA display modes: Each VGA output lists 1920 × 1080, 1280 × 1024, 1280 × 720 or 1024 × 768 at 60 Hz.
Display output pairing: HDMI 1 and VGA 1 provide simultaneous main output; HDMI 2 and VGA 2 provide simultaneous auxiliary output. Four connectors do not mean four independent source views.
CVBS video output: One BNC CVBS output, 1.0 Vp-p at 75 Ω: PAL 704 × 576 or NTSC 704 × 480. Separate from IP input resolution.
Audio outputs: Two RCA line-level audio-output channels, 1 kΩ. This is not a built-in microphone or speaker claim.
Two-way audio connection: One RCA two-way audio channel, 2.0 Vp-p at 1 kΩ, using the audio input. Confirm the connected microphone, output device and client.
Video codec reference: H.265+, H.265, H.264+ and H.264 are listed. Confirm camera, client and recorder configuration; no fixed storage saving is guaranteed.
Recording-resolution list: 32, 24, 12, 8, 7, 6, 5, 4 and 3 MP, 1080p, UXGA, 720p, VGA, 4CIF, DCIF, 2CIF, CIF and QCIF are listed. This list does not specify simultaneous decoding counts or frame rates.
Synchronous playback: 16-channel synchronous playback is listed independently of IP inputs and decoding capacity.
Audio codec reference: G.711ulaw, G.711alaw, G.722, G.726, AAC, MP2L2 and PCM are listed. Confirm the actual stream and client compatibility.

Network, storage and interfaces

Ethernet interfaces: Two self-adaptive 10/100/1000 Mbps RJ45 Ethernet interfaces. No PoE output, automatic link aggregation or doubled recording bandwidth is inferred.
Network protocol reference: The protocol row includes TCP/IP, DHCP, IPv4/IPv6, DNS, DDNS, NTP, RTSP, SADP, SMTP, SNMP, NFS, iSCSI, ISUP, UPnP, HTTP and HTTPS. This is not an enabled-service or universal interoperability claim.
Remote-access reference: Hik-Connect and DDNS are named in the manufacturer feature list. Account, network, service availability and security configuration require confirmation; no live ISD integration is claimed.
Browser-access reference: Web access without a plug-in is listed. Check the actual browser and installed firmware; this is not a current-browser or security-support guarantee.
Camera analytics reference: The source describes configurable functions with special cameras, including VCA, heat map, ANPR and people counting. This is not proof of recorder-side AI or those functions on every connected camera/channel.
POS function reference: POS information overlay on live view and playback, plus POS-triggered recording and alarm, are listed. Confirm POS interface and configuration; a POS terminal is not assumed included.
SATA connections: Eight SATA interfaces are listed. Drives are not assumed included; interface count is not usable or guaranteed total storage.
eSATA connection: One eSATA interface is listed. Confirm external storage and configuration.
RAID modes: RAID 0, 1, 5, 6 and 10 are listed. Required disks, usable capacity and recovery need confirmation; RAID is not a backup or a no-data-loss guarantee.
Hot-spare feature reference: N+M hot spare is listed as a system feature. Additional recorders, network design and configuration are not assumed included.
Serial connections: One full-duplex RS-485 and one RS-232 interface. Confirm device protocol and wiring.
Alarm connections: 16 alarm inputs and nine alarm outputs are listed. Counts do not establish external contact ratings.
USB connections: Front: two USB 2.0 ports. Rear: two USB 3.0 ports. Confirm supported peripherals and export workflow.
Controlled alarm power output: Ctrl 12V is a controllable 12 V DC, 1 A output for an external alarm device, controlled by alarm output nine. It is not the recorder mains power input.
DC auxiliary power output: A separate 12 V DC, 1 A output is listed. This is an output, not a 12 V recorder-input requirement.
Dual-stream recording reference: Dual-stream recording is listed. Actual camera streams, bandwidth and retention depend on configuration.
Per-drive capacity reference: Up to 14 TB per disk in this cited US datasheet. Confirm the supplied edition, approved drive models and firmware; no total, usable RAID capacity or included HDD is implied.

Power, environment and selection

AC power input: 100–240 V AC, 50–60 Hz. Distinct from the 12 V auxiliary outputs.
Diskless consumption: At most 50 W without HDDs. Do not use this as the loaded recorder or UPS power budget.
Operating temperature: -10 to +55 °C. Confirm enclosure ventilation and actual operating conditions.
Working humidity: 10–90% humidity is listed. No additional condensation or outdoor-protection rating is inferred.
Chassis reference: 2U chassis. Rack accessories, mounting depth, cable clearance and ventilation require confirmation.
Stream transport reference: Stream-over-TLS technology is listed. Confirm firmware and enabled settings; this is not an all-connections encryption or security-certification claim.
Playback verification reference: Double verification for playback and downloading is listed. Confirm the actual configuration; no deployed authentication workflow is claimed.
Specified dimensions: The table states 445 × 465 × 93 mm (width × depth × height). The drawing also labels 475 mm extended depth and 88/93 mm heights; these are not ventilation, rack or cable-clearance requirements.

Selection notes

These references apply only to the complete printed DS-9664NI-M8 model and the cited document. Confirm the supplied region, hardware, firmware, disks, cameras, display modes and configuration; manufacturer references are not ISD supply or performance guarantees.
Confirm decoding modes and weight configuration for the supplied edition before system sizing; no value is assigned here.
Special-camera analytics, hot spare, remote access, playback verification and storage features require compatible equipment and configuration; none establishes an active ISD integration.
Manufacturer documents do not confirm stock,price,ETA,local warranty,authorisation,current security support or Malaysian compliance. ISD supplies products only.
Drives,cameras,cables,rack accessories,licences and power equipment are not assumed included. RAID and hot spare are not substitutes for backup.
