A modern video door phone does far more than a doorbell — it verifies visitors with live video, connects two-way audio, releases doors remotely and logs every entry, all over your IP network. As an authorized distributor, Cohesive Technologies offers a complete door-entry and SIP-intercom portfolio in India, bringing Grandstream, Akuvox and CyberData together so you can specify, source and support the whole system from one partner.
Grandstream GDS video and audio door systems — GDS3710, GDS3712, the GDS3720 Series, GDS3705 and GDS3702 — combine SIP video intercom, card reader and door control in a single rugged unit. Akuvox adds a broad line of SIP video door phones and AI facial-recognition stations, plus a 2-wire range that delivers full IP video intercom over existing two-wire cabling for effortless retrofits. CyberData completes the range with weather-resistant outdoor, H.264 video and hands-free emergency SIP intercoms for gates, help points and public-safety locations.
Whether you are securing an office lobby, an apartment complex, a factory gate, a hospital, a campus or a car-park help point, there is a matching door station in this range. Every unit is a standard SIP endpoint, so it rings to Grandstream, Snom and Yeastar IP phones, registers to common IP-PBX platforms and ties into building access control through built-in relays and door-strike modules. Cohesive Technologies backs each brand with expert consultation, genuine stock, design help, competitive pricing and nationwide delivery across India, Sri Lanka, Nepal and the Maldives.
