Zamel Wireless Doorbells

Zamel Wireless Doorbells (often branded under Sundi) provide a range of battery-operated and plug-in chime systems designed for wire-free installation and flexible home coverage. At DoorbellWorld, we classify Zamel’s wireless range as particularly strong in operating distance and alert customisation, with most models supporting 100–300 metre open-field range on 433 MHz, and selected models extending significantly further.

The ST-420 (Dance II) series offers up to 300 m range, 60 melodies, and multi-step volume control, while the BULIK II PRO (DRS-995) uses LoRa radio technology to achieve up to ~1400 m range, supports MP3 uploads, and can pair with large numbers of transmitters.

Other ranges such as SATTINO (ST-230), JAZZ (ST-260), and SAMBA II (ST-955) focus on compact design, touch-sensitive controls, or battery-free push buttons. Across the range, Zamel models typically offer IP44/IP55-rated weatherproof buttons, LED visual alerts, multi-button pairing, and volume output up to ~85–90 dB, making them suitable for larger properties, thicker walls, and multi-entrance setups.
