The monitor supports refresh rates up to 100 Hz through HDMI and has a 6 ms overdrive response time for smoother motion.

Key Capabilities
Full HD CCTV Display
The 1920 × 1080 native resolution provides clear viewing of recorder menus, camera grids, playback footage and general desktop content. It is well suited to systems where a compact Full HD display is sufficient.
Continuous 24/7 Operation
The monitor is specified for continuous operation, making it more appropriate for security monitoring and commercial environments than a display intended only for occasional home or office use.
Wide Viewing Angles
The VA panel provides 178° horizontal and vertical viewing angles, helping maintain consistent visibility when the monitor is viewed from the side, above or below its central position.
HDMI and VGA Connectivity
One HDMI 1.4 input and one VGA input allow the monitor to connect to modern and legacy recorders or computers. The selected source must provide a supported resolution and refresh rate.
Up to 100 Hz Refresh Rate
The HDMI input supports Full HD operation up to 100 Hz, helping motion appear smoother when the connected source provides a compatible output. VGA operation supports Full HD up to 60 Hz.
Built-In Stereo Speakers
Two integrated 1.5 W speakers provide basic audio output for compatible CCTV footage, system notifications and computer use without requiring separate desktop speakers.
Best For
- CCTV Monitoring Desks: Suitable for viewing live cameras, playback and recorder menus throughout the day.
- Reception Areas: Provides a compact security display for front-desk staff monitoring entrances and visitor activity.
- Retail Stores: Useful for displaying camera grids behind counters or in compact security areas.
- Small Offices: Works as a combined CCTV and general-purpose Full HD computer monitor.
- Wall-Mounted Displays: Supports a standard 75 × 75 mm VESA bracket for compatible wall installations.
Why Choose the DHI-LM22-H200
The DHI-LM22-H200 is a practical choice when a CCTV system needs a compact Full HD display built for continuous operation. Its 21.45-inch screen is large enough for recorder menus and smaller multi-camera layouts without occupying the desk space of a larger commercial monitor. The VA panel provides strong contrast and wide viewing angles, while HDMI and VGA inputs support both newer and older video sources. Built-in speakers reduce the need for separate audio equipment, and the 75 × 75 mm VESA pattern allows the screen to be moved off the desk when required. Available through Security Wholesalers, this model suits small monitoring stations, offices, shops and reception areas where dependable 24/7 operation is more important than 4K resolution, network decoding or advanced multi-input display functions.
Buyer Decision Tips
Buyer Tip: This monitor has a native resolution of 1920 × 1080. A 4K recorder can still be connected if it supports a compatible Full HD output setting, but the monitor will not display a native 4K image.
Buyer Tip: Confirm the required mounting method before ordering. The desktop base is included, while a compatible 75 × 75 mm VESA wall bracket is optional and must be selected separately.

FAQs
- Is the Dahua DHI-LM22-H200 suitable for continuous CCTV monitoring?
Yes. The DHI-LM22-H200 is specified for continuous 24/7 operation, making it suitable for security control rooms, reception desks and other monitoring points that require extended daily use. Correct ventilation, a stable power supply and operation within the stated temperature and humidity limits are still important for reliable long-term performance.
- What resolution does the DHI-LM22-H200 support?
The DHI-LM22-H200 has a native Full HD resolution of 1920 × 1080. Its HDMI 1.4 input supports up to 1920 × 1080 at 100 Hz, while the VGA input supports up to 1920 × 1080 at 60 Hz. The connected recorder or computer should be configured to a supported output resolution and refresh rate.
- Does the DHI-LM22-H200 have built-in speakers?
Yes. The DHI-LM22-H200 includes two built-in 1.5 W speakers and provides an audio input. This can be useful when the connected recorder or computer supplies audio through the selected connection. Sound output is intended for basic monitoring and interface use rather than high-volume public-address applications.
- Can the DHI-LM22-H200 be wall mounted?
Yes. The DHI-LM22-H200 supports a 75 mm × 75 mm VESA wall-mount pattern. The wall bracket is optional, so confirm that the selected mount supports the monitor’s dimensions and 2.3 kg net weight. Use suitable fixings for the wall type and allow access to the HDMI, VGA, audio and power connections.
- What connections are available on the DHI-LM22-H200?
The DHI-LM22-H200 provides one HDMI 1.4 input, one VGA input and one audio input. This allows connection to many CCTV recorders, computers and other compatible video sources. It does not include DisplayPort, USB-C or network video decoding, so the source device must provide a suitable HDMI or VGA output.
- What should be checked before buying the DHI-LM22-H200?
Confirm the required screen size, Full HD resolution, preferred HDMI or VGA connection, audio requirements, mounting method and available desk or wall space before ordering. The DHI-LM22-H200 is available through Security Wholesalers for compatible CCTV monitoring applications, but it should not be treated as including an optional wall bracket or recorder.
