The HKM02BP-4K is a 4K30Hz, highly flexible HDMI® KVM Matrix system that supports a 1G PoE switch, designed to scale with your project. Available in 1080P (HKM02B), 4K30Hz (HKM02BP-4K), or 4K60Hz (HKM02BP-4K6G), it allows you to customize the exact number of Encoders and Decoders based on your site requirements. Featuring dual-medium support for both CAT5e/6 and fiber-optic transmission, it seamlessly adapts to any infrastructure. With integrated Mouse Roaming, operators can control multiple PCs by simply moving the cursor across monitor borders. It is the perfect all-in-one solution for Response/Control Centers, large-scale security, and mission-critical routing. Note: Different resolution versions are not compatible and cannot be mixed within the same system.

Features
Flexible, Customizable Video Wall

Mouse Roaming for Seamless Multi-PC Control
Streamline your workflow with Mouse Roaming. Control multiple PCs using a single keyboard and mouse by simply moving the cursor across monitor borders. This hardware-based switching eliminates hotkeys, providing intuitive, real-time multitasking—perfect for enhancing efficiency in high-pressure Response Centers and mission-critical environments.

Multiple Control Options
Multiple control options to meet different project requirements.

RS232 for Customized Control
Use the RS232 command list provided in the SC&T user manual to build a customized control interface.

Long-Lasting Durability
Built-in circuit protection components to prevent the devices from surge spikes.

Ethernet Switch Requirement
At least using a Gigabit Ethernet switch that supports IGMP, and enabling Jumbo Frame is recommended.
When using more than one Ethernet switches to expand your AV system, please choose cables that can carry the total amount of data (Use a fiber cable when using 8 TX and 8 RX or more).
Optional 1U Rack-Mount Kit

For control rooms and AV racks, the 1U rack panel helps keep multiple SC&T devices aligned and easier to maintain.
- Designed for selected SC&T device sizes for cleaner rack organization
- Easy installation with included screw set and illustrated manual
- Standard 19" rack format, 1U height
SC&T AV over IP Setup Guide
SC&T AVoIP tutorial videos are divided into two parts: The first part is the basic setup video, and the second part will be an advanced video wall tutorial, in which we will cover advanced settings and software operations.
In this video, you will learn how to:
- Set up Jumbo Frame and IGMP Snooping on the switch
- Set the Tx channel via one of the following methods:
1. Use the device buttons/rotary switch
2. Enter the RS232 command using PuTTY/RS232 software
3. Use the remote control with the screen panel/RS232 software
By following the steps, you can easily set up the video matrix and control it using different methods, such as a remote control or software.
Benefits
- Multiple control options for different project requirements
- Budget-friendly 1G network architecture
- Supports both CAT cable and fiber for flexible distance planning
- Supports a wide range of USB 2.0 devices, such as USB flash drives and webcams
