The TUYA TY75T-HTD2 is a two-wire video intercom kit designed for buildings where pulling new cable is expensive or impossible. The indoor monitor connects to the door station over a two-core pair (RVV2), carrying video, audio, unlock control and power. That makes it a practical upgrade for older apartment blocks and villas with existing doorbell wiring.
The 7-inch IPS touch monitor offers 1024 × 600 resolution, supports a TF card up to 64 GB, and can be powered from AC 100–240 V. The door station uses a 2 MP AHD sensor (1/2.9-inch CMOS, 2.8 mm lens) with a 120° angle and a compact 145 × 90 × 45 mm housing. The kit supports a 150 m cable run over RVV2 and one door station with indoor units.
Use it for apartment buildings, villas, small offices and gatehouses where the existing two-wire cable is in good condition. If the site has network cabling and needs app answering across multiple buildings, choose an IP kit instead. For multi-apartment keypad entry, the TY76A-HM5-1B adds a keypad door station.
