Dahua VTH8A21KMS-CW

The Dahua VTH8A21KMS-CW Android IP & Wi-Fi Indoor Monitor is a professional video-intercom station designed for apartments, villas, offices, hotels and residential developments. It features a 7-inch full-color capacitive touchscreen with 1024 × 600 resolution, runs on Android 8.1, and supports installation of compatible Android applications. The key advantage of the “-CW” version is its built-in 2 MP CMOS camera with a 2 mm lens, enabling house-to-house visible communication in addition to standard door-station video calls. It supports H.264 video, full-duplex two-way audio, G.711a/G.711u/PCM audio codecs, Wi-Fi, SIP, RTSP, TCP/UDP networking, information messages from the management center, configurable Do Not Disturb periods, SOS functionality, 6 alarm inputs and 1 alarm output, and microSD/TF storage up to 64 GB. It can be powered by 12–24 VDC or Standard PoE, uses an aluminum + ABS enclosure, and supports up to 9 extensions in villa applications, 4 in apartment configurations, or 1 main plus 2 extension monitors in Wi-Fi intercom mode. The related VTH8A21KMS-W uses the same 7-inch 1024 × 600 Android 8.1 platform, Wi-Fi connectivity, 6 alarm inputs, 1 alarm output, TF card support up to 64 GB, PoE/12–24 VDC power and the same extension capacities, but does not include the built-in 2 MP camera, so it is intended primarily for standard house-to-house audio communication and door-station video display. The larger VTH8A41KMS-W expands the user interface to a 10-inch 1024 × 600 capacitive touchscreen while retaining Android 8.1, Wi-Fi, SIP/RTSP networking, 6 alarm inputs, 1 alarm output, microSD support up to 64 GB and Standard PoE or 12–24 VDC power. Its larger 190 × 250 mm body makes it especially suitable for reception areas, premium apartments and projects where a larger visual interface is preferred. In practical terms, the VTH8A21KMS-CW is the best option when an integrated indoor camera is required, VTH8A21KMS-W suits standard 7-inch intercom applications, and VTH8A41KMS-W provides the same core architecture with a larger 10-inch display.
