Ecrã Dahua VTH5422HB — ecrã monitor interior, 12V DC, 6 W típico, Ethernet 10/100 Mbit/s, preto

The Dahua VTH5422HB is a 7" indoor monitor designed for access control and intercom systems. It features a capacitive touch TFT display with 2.5D glass and a bezel-less full-screen design. The unit supports wired network connection via 10/100 Mbps Ethernet and standard Power over Ethernet (PoE), as well as power and communication over a two-wire bus. It provides multiple alarm inputs and a compact black housing for wall-mounted installations in residential and commercial buildings.

Advantages

The display offers responsive capacitive touch control and clear video decoding with support for H.265 and H.264 formats. With PoE support and two-wire power/communication options, installation is flexible for new or retrofit projects. Six alarm inputs and one alarm output allow integration with external sensors and systems, while daisy-chain topology and one-tap call to the management center simplify multi-unit deployments.

Suitable for

• Apartment entry systems and multi-dwelling intercoms
• Villas and single-family home access panels
• Small commercial premises and office reception areas
• Wall-mounted internal monitoring and visitor communication points

When it may not be suitable

This indoor monitor is intended for wall-mounted access control and intercom use; it may not be appropriate where a larger display, outdoor-rated enclosure, or wireless-only connectivity is required. Environments demanding specialized industrial protection or extreme temperature resistance should consider purpose-built devices.

How to use

Mount the unit on a standard interior wall at a comfortable viewing height and connect either 12 V DC power or a PoE-enabled Ethernet cable. For systems using two-wire communication, connect the two-wire bus and, if needed, the two-wire power switch. Integrate alarm sensors to the alarm input terminals and configure the device via the system management interface to enable call-to-center, video decoding preferences, and network settings. Use the capacitive touchscreen for local control and communication with visitors.

What to consider before purchase

• Whether your installation supports PoE or requires 12 V DC power
• Compatibility with your existing intercom/access control system and two-wire topology
• Number and type of external sensors needing alarm inputs
• Mounting location and indoor environmental conditions

Recommendations

For reliable operation, use a stable PoE switch or a regulated 12 V DC power supply, configure network and codec settings to match your recording/monitoring system, and test alarm inputs during installation to confirm correct wiring and response.
