ENS SD5432/48I-K 32-Channel 8MP Turbo HD DVR
What happens when your surveillance system grows, but your recorder becomes the part holding everything back?
The SD5432/48I-K is built for larger security installations that need room to expand without forcing you to abandon existing camera infrastructure.
With 32 analog channels, IP expansion up to 48 channels, recording up to 8 MP, and support for multiple video technologies, it gives you flexibility today while leaving room for what you may need tomorrow.
Add high-capacity RAID storage, 4K display output, smart event detection, and efficient H.265 Pro+ compression, and you have a recorder designed to make managing a large surveillance system simpler and more dependable.
Why Buyers Choose the SD5432/48I-K
If you are already managing dozens of cameras, would it make more sense to replace everything when you expand—or use a recorder that can work with what you already have?
The SD5432/48I-K combines high channel capacity, hybrid camera compatibility, flexible storage, and professional monitoring features in one platform.
32 Analog Channels + IP Expansion — Build a Larger System Without Starting Over
Connect up to 32 analog cameras while gaining support for IP camera expansion up to 48 IP channels.
This gives larger properties room to grow and provides a practical path for adding higher-resolution network cameras as surveillance requirements change.
HDTVI, AHD, HDCVI, CVBS & IP Support — Keep More of Your Existing Infrastructure
Instead of being locked into one camera technology, the SD5432/48I-K supports multiple analog formats plus IP cameras.
That flexibility can make upgrading an existing surveillance system easier because compatible cameras and coaxial infrastructure may continue to be used while newer technology is introduced.
Up to 8 MP Recording — Capture More Useful Detail
Full-channel recording is supported at resolutions up to 8 MP.
Higher-resolution recording gives your surveillance system the ability to preserve more image detail when reviewing important events.
4K HDMI Output — See Your System on a High-Resolution Display
The HDMI2 output supports resolutions up to 4K at 3840 × 2160.
For large multi-camera systems, that gives you a higher-resolution monitoring option when viewing cameras and recorded footage on a compatible display.
H.265 Pro+ Compression — Make Better Use of Your Storage
H.265 Pro+ is designed to improve encoding efficiency and reduce video storage requirements.
That means your available hard drive capacity can be used more efficiently instead of unnecessarily filling with oversized video files.
4 SATA Bays with Up to 10 TB Per Drive — Storage Built for Larger Camera Counts
Four SATA interfaces support drives with capacities up to 10 TB each, with an additional eSATA interface available.
For a system recording many cameras around the clock, that gives you significantly more flexibility when planning video retention.
RAID & Hot-Swappable HDD Support — Add Storage Resilience
The recorder supports hot-swappable HDDs along with RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10 configurations.
This gives professional installations more options for balancing usable capacity, performance, and storage redundancy according to the needs of the system.
Long-Distance HDTVI Transmission — Cover Larger Properties
HDTVI signals can reach up to 800 meters at 1080p and up to 1200 meters at 720p.
That makes the recorder especially useful for larger facilities where cameras may need to be installed a considerable distance from the recording equipment.
Line Crossing & Intrusion Detection — Focus on Events That Matter
Video Content Analytics support includes line crossing and intrusion detection across all channels, along with sudden scene change detection on two channels.
Instead of relying only on continuous video, these tools help the system identify defined activity that may deserve closer attention.
Smart Search — Spend Less Time Looking Through Footage
When something happens, finding the relevant recording should not mean endlessly searching through hours of video.
Smart search is designed to make playback review more efficient so important footage can be located faster.
16-Channel Synchronous Playback — Review Multiple Views Together
The DVR supports synchronous playback of up to 16 channels.
When an event moves from one camera to another, reviewing multiple viewpoints together can make it easier to understand the complete sequence of what happened.
Hik-Connect & Network Access — Stay Connected to the Recorder
Hik-Connect, DDNS, and a wide range of network protocols are supported, along with up to 128 remote connections.
Dual Gigabit Ethernet interfaces also provide the network connectivity expected in larger surveillance environments.
POS-Triggered Recording — Connect Transactions With Video
For retail applications, the recorder supports POS-triggered recording and POS information overlay.
This can help businesses connect transaction information with corresponding surveillance footage when reviewing activity around checkout areas.
Alarm I/O Integration — Connect Surveillance With Other Security Events
With 16 alarm inputs and 4 alarm outputs, the recorder can support installations where video surveillance needs to interact with compatible external alarm devices or security events.
Third-Party Cloud Storage Support — Add Another Storage Option
The SD5432/48I-K supports third-party cloud storage through Dropbox, Google Drive, and Microsoft OneDrive, providing additional flexibility for compatible storage workflows.
What This Means for Your Security System
- Manage a large number of cameras from one recorder.
- Combine compatible analog and IP camera technologies in the same system.
- Upgrade gradually instead of automatically replacing your entire existing surveillance infrastructure.
- Record video at resolutions up to 8 MP for greater captured detail.
- Expand local storage using four SATA drives with capacities up to 10 TB each.
- Choose from multiple RAID configurations when storage redundancy is important.
- Monitor on a compatible 4K display through the HDMI2 output.
- Use smart detection and search tools to make reviewing recorded events more efficient.
- Support long HDTVI cable runs for larger buildings and properties.
- Integrate POS information and alarm devices into compatible surveillance applications.
What This Helps You Avoid
Imagine discovering that your current recorder is full just when you need to add another group of cameras.
Or realizing that upgrading means replacing cameras and infrastructure that are still perfectly usable.
For larger systems, limitations like these can turn what should be a straightforward expansion into an expensive and complicated project.
The SD5432/48I-K approaches that problem differently.
Its hybrid video support lets compatible analog and IP technologies work within the same recording platform, while its channel capacity gives you considerably more room to design or expand the system.
Then there is storage.
Multiple high-resolution cameras can create substantial amounts of video, so H.265 Pro+ compression, four SATA interfaces, up to 10 TB per drive, eSATA, and multiple RAID options give you more control over how that footage is stored and protected.
And when an incident actually happens, the value of a surveillance system is not simply that it recorded something—it is how quickly you can get to the footage you need.
Smart search, VCA event detection, and 16-channel synchronous playback help turn a large collection of recordings into a system that is easier to investigate.
The result is a recorder built for buyers who would rather invest in a surveillance platform with room to adapt than discover later that their recorder has become the limitation of their entire security system.
