The Hikvision DS-7732NI-M4 is a 32-channel M Series 8K network video recorder without built-in PoE ports, giving the same true 8K video output and high-resolution decoding as its /16P and /24P siblings, for sites that already have PoE switching infrastructure in place or prefer to power cameras separately from the recorder.
Hikvision DS-7732NI-M4 32-Channel 8K NVR
Up to 32 IP camera channels are supported, with resolution up to 32MP per channel and up to 8 channels at 32MP/24MP when Ultra HD mode is enabled. HDMI 1 supports true 8K output at 30Hz alongside 4K, 2K and 1080p fallback resolutions, and independent HDMI and VGA outputs provide dual 4K HDMI capability when full 8K isn't required.
With 320 Mbps incoming and 400 Mbps outgoing bandwidth, and up to 4 SATA interfaces for on-board storage, this recorder is built for control-room style deployments recording a genuinely large number of feeds. Because it has no built-in PoE, it's a more cost-effective choice for sites where camera power is already handled by existing network infrastructure.
8K Video Output
HDMI 1 supports resolutions up to 8K (7680 × 4320) at 30Hz, with 4K/60Hz, 4K/30Hz, 2K/60Hz and 1080p/60Hz as fallback options, and dual 4K HDMI output when full 8K isn't required.
No Built-In PoE
Unlike the DS-7732NI-M4/16P and DS-7732NI-M4/24P, this model has no built-in PoE ports, making it the right choice for sites that already have PoE switching in place or want to avoid paying for built-in ports they won't use.
Storage & Bandwidth
Up to 4 SATA interfaces support on-board storage, with 320 Mbps incoming and 400 Mbps outgoing bandwidth keeping pace with a genuinely large 32-channel camera estate.

Frequently Asked Questions
What is the difference between this and the /16P or /24P models?
All three share the same core 32-channel, 8K-capable platform. This base model has no built-in PoE ports, while the /16P and /24P variants add 16 or 24 built-in PoE ports respectively for direct camera power delivery.
Can it output true 8K video?
Yes, HDMI 1 supports 7680 × 4320 at 30Hz.
Does it work with third-party PoE switches?
Yes, since it has no built-in PoE of its own, cameras are typically powered via a separate PoE switch or injectors, which this model is well suited to since you're not paying for unused built-in ports.
How much storage can it support?
Up to 4 SATA interfaces for on-board drives.
What does "Ultra HD mode" do?
When enabled, it allows up to 8 channels to run at 32MP or 24MP resolution simultaneously, reducing the decoding budget available to lower-resolution channels.
Can it drive two separate displays?
Yes, independent HDMI and VGA outputs are provided, with dual 4K HDMI output supported as an alternative to full 8K.
Does it handle unreliable network connections well?
Yes, Hikvision's advanced streaming technology is designed to maintain smooth live view even over degraded or congested network links.
Does it support IP speakers?
Yes, up to 8 channels of IP speakers can be connected for audible alerts.
