ENS SD2432/48I-K H.265+ 32-Channel Hybrid Digital Video Recorder
What if expanding your security system didn”t mean replacing every camera you already have? The ENS SD2432/48I-K gives you the flexibility to combine HDTVI, AHD, HDCVI, CVBS, and IP cameras in one powerful recorder, making it easier to build around your existing infrastructure while leaving room for future expansion.
With 32 analog channels and support for up to 48 IP camera inputs at resolutions up to 6MP, this recorder is built for larger surveillance systems where capacity and flexibility matter.
H.265+ compression, 4K monitor output, dual-drive storage support, long-distance HDTVI transmission, VCA events, alarm integration, and POS recording give you more than a place to store video—they give you a centralized platform designed to make managing a large security system easier.
Why Buyers Choose the ENS SD2432/48I-K
When you”re responsible for dozens of cameras, the question isn”t simply whether a recorder can display video. It”s whether the system gives you enough flexibility, storage, connectivity, and expansion capacity to keep working as your security needs change.
32 Analog Channels + Up to 48 IP Cameras — Expand Without Starting Over
Connect up to 32 analog cameras while also taking advantage of IP camera technology. The recorder supports 16 IP channels and can be expanded to as many as 48 IP camera inputs, giving you a practical path to grow your surveillance system without immediately abandoning compatible existing cameras.
Multi-Format Camera Compatibility — More Freedom When Choosing Cameras
Support for HDTVI, AHD, HDCVI, CVBS, and IP video means you”re not limited to a single video format. That flexibility can be especially valuable when upgrading an existing property where different generations or types of cameras may already be installed.
Up to 6MP IP Camera Support — Capture More Useful Detail
The SD2432/48I-K supports IP camera resolutions up to 6MP, allowing compatible higher-resolution cameras to become part of the same centralized surveillance system.
H.265+ Compression — Make Better Use of Your Storage
H.265+ video compression is designed to encode surveillance video more efficiently, helping you make better use of available storage and network resources while maintaining the video your security system depends on.
Dual SATA Storage — More Recording Capacity Where It Matters
Two SATA interfaces support hard drives with capacities of up to 10TB each. That gives larger camera systems significantly more room for recorded footage before older video needs to be overwritten, depending on your camera count, resolution, frame rate, bitrate, and recording settings.
4K HDMI Output — See Your Security System on a High-Resolution Display
HDMI2 supports output up to 3840 × 2160 at 30 Hz, giving you the ability to connect a compatible 4K monitor for a larger, more detailed surveillance viewing experience.
16-Channel Synchronous Playback — Review Multiple Angles Together
When something happens, looking at only one camera may not tell the entire story. With synchronous playback of up to 16 channels, you can review multiple camera views together and build a clearer picture of how an event unfolded.
Long-Distance HDTVI Transmission — Cover Larger Properties
The recorder supports HDTVI signal transmission of up to 800 meters at 1080P and up to 1,200 meters at 720P over supported UTP or coaxial cabling. For large properties, this gives installers considerably more flexibility when cameras need to be positioned far from the recorder.
VCA Event Support — Turn Recorded Video Into More Useful Security Information
Support for multiple Video Content Analytics events with compatible analog and smart IP cameras adds another layer of intelligence to the surveillance system, helping you work with event-based information instead of relying only on continuous video.
POS-Triggered Recording — Connect Transactions With Video
For retail environments, the recorder supports POS-triggered recording and POS information overlay. This can make it easier to review video alongside transaction information when investigating activity around a register or checkout area.
16 Alarm Inputs / 4 Alarm Outputs — Build a More Integrated Security System
The built-in alarm connections allow the recorder to become part of a broader compatible security setup instead of functioning only as a video recorder.
Gigabit Ethernet — Built for a Larger Networked Surveillance System
A self-adaptive 10/100/1000 Mbps RJ-45 network interface provides Gigabit Ethernet connectivity for network cameras, remote access, and other supported network functions.
Up to 128 Remote Connections — Give Authorized Users Greater Access
Support for up to 128 remote connections makes the recorder better suited to environments where surveillance access may need to extend beyond the monitor sitting beside the DVR.
Two-Way Talk Support — Add Voice Communication Where Needed
An independent RCA two-way talk connection provides additional flexibility for surveillance applications that require supported two-way audio communication.
USB 3.0 Connectivity — Faster Access for Supported Local Tasks
The recorder provides two front USB 2.0 ports and one rear USB 3.0 port, giving you convenient connectivity for compatible USB devices and local recorder operations.
What This Helps You Avoid
Imagine your property already has dozens of working coax cameras, but now you want to add newer IP cameras. Do you really want to replace an entire surveillance infrastructure simply because your recorder can”t accommodate both?
That”s the problem a hybrid recorder like the SD2432/48I-K is designed to solve. Instead of forcing you into one video format, it gives you a way to work with HDTVI, AHD, HDCVI, CVBS, and IP video from one recorder.
It also helps prevent another common problem: outgrowing the recorder. With 32 analog inputs and the ability to support up to 48 IP camera inputs, you have substantially more room to expand than with a smaller-channel system.
And when an incident actually happens, having cameras isn”t enough if reviewing the evidence becomes a frustrating process. Features such as 16-channel synchronous playback, VCA event support, POS information overlay, 4K display output, and alarm integration give you more ways to organize and work with the information your system captures.
The result is a surveillance recorder built for the buyer who wants to protect an existing investment today while maintaining the flexibility to expand tomorrow—without making the recorder the bottleneck of the entire security system.
