Smarter, Safer, Connected Campuses
Keep students safe and staff connected across every classroom, corridor and open ground. Cohesive Technologies designs, supplies and supports IP paging and mass notification, campus phones, surveillance, secure entry and Wi-Fi for schools, colleges and universities across India, Sri Lanka, Nepal and the Maldives.
Communication and safety, campus-wide
A campus is a small city — classrooms, laboratories, offices, hostels, libraries, canteens and open grounds, all needing to stay connected and, above all, safe. Cohesive brings communication and security together on one IP platform, so a bell schedule, a corridor announcement, an office call and an emergency lockdown alert all run over the same reliable network.
We help institutions automate class bells and public-address, reach every zone instantly during an emergency, secure gates and hostels with access control and video entry, watch over corridors and perimeters with AI surveillance, and blanket the whole campus in fast, managed Wi-Fi — all delivered at education-friendly budgets.
From a single school building to a multi-block university, our engineers plan and roll out deployments around your academic calendar, so upgrades happen during breaks and never disrupt teaching.
An end-to-end campus technology stack
Purpose-built for education — deploy what you need today and expand across buildings and campuses as you grow.
IP Paging & Mass Notification
Automate class bells, make clear announcements to any zone, and trigger instant campus-wide alerts during an emergency or lockdown. SIP speakers, horns and displays work over your existing network — with scheduled bells, live and pre-recorded messages, and one-button emergency broadcast to every classroom and open ground.

Campus Surveillance & Safety
Protect students, staff and property with AI network cameras and NVR/VMS across classrooms blocks, corridors, labs, hostels, car parks and perimeters. Intelligent analytics — intrusion detection, loitering and licence-plate recognition at gates — add both safety and accountability, with 24×7 recording and email alerts.

Campus Telephony & IP-PBX
Connect staff rooms, departments, HOD cabins, labs and administration on one modern IP-PBX. Multi-level auto-attendant routes parent and admissions calls to the right desk, while call paging, pickup and transfer make day-to-day coordination between offices and classrooms effortless.

Secure Entry & Access Control
Control who enters the campus and restricted areas. IP video door stations at gates and receptions route visitor calls to the office, while card, PIN, face and mobile-credential access secures labs, libraries, hostels and admin blocks — with a full audit trail of every entry.

Campus-Wide Wi-Fi & Networking
Deliver reliable, secure connectivity to classrooms, labs, libraries, hostels and staff areas. Cloud-managed Wi-Fi 7/6 access points, PoE switches and routers provide high-density coverage, separate student/staff/guest networks, content filtering and central management across every block and campus.
