Project Title: Integration of IP Video Intercom with MyGate App for Automated Sliding Door Access 1. Project Overview Our society has installed automatic sliding doors with existing biometric access. We need to implement a "Buzz-In" Video Intercom system that allows unscheduled visitors (vendors, delivery, guests) to call residents. Residents must be able to view the visitor and trigger the door to open directly from their MyGate smartphone app. 2. Technical Stack & Components Existing Hardware: Automatic Sliding Door with a Motor Controller (supporting Dry Contact/Wiegand input). Desired Hardware: SIP-enabled IP Video Intercom (e.g., Hikvision DS-KV series, Dahua, or Akuvox). Platform: MyGate (Resident Management App). Integration Method: MyGate Hardware Access APIs (RESTful APIs) and a Hardware Controller (Relay). 3. Scope of Work (Step-by-Step) Phase 1: API & Middleware Development MyGate API Integration: Utilize MyGate’s Hardware Access APIs (specifically the /notify and /sync endpoints) to link the society’s resident database with the Intercom’s dialing directory. Call Routing Logic: Configure a SIP server or cloud bridge so that when a visitor dials a flat number on the Intercom, it triggers a "Push Notification" or "VOIP Call" to the specific resident registered in the MyGate database. Phase 2: Remote Unlock Command (The "Buzz-In") Signal Mapping: Program the "Allow/Unlock" button within the MyGate app interface to send a command to the gate controller. Hardware Trigger: Ensure the command triggers a Dry Contact Relay on the MyGate-integrated controller (e.g., MyGate Access Node) connected to the sliding door's "Push Button" terminals. Phase 3: Hardware Sync & Logs Data Synchronization: Automate the sync between MyGate resident moves (move-in/move-out) and the Intercom directory so the kiosk is always up to date. Audit Trail: Every successful "Buzz-In" must generate a log in the MyGate Admin Dashboard showing: Visitor Image (from Intercom), Flat Number, Time, and Resident Name who granted access. 4. Deliverables Middleware/Script: A hosted service (or local server setup) that bridges the Intercom’s SIP calls to MyGate’s notification engine. Hardware Configuration: Setup and wiring diagram for the Intercom-to-Door-Motor connection. Documentation: API documentation for the custom bridge and a troubleshooting guide. 5. Required Freelancer Skills Experience with MyGate / NoBrokerHood API integrations. Strong knowledge of VoIP / SIP Protocols and IP Intercom hardware (Hikvision/Dahua). Proficiency in Node.js, Python, or Java for middleware development. Understanding of IoT Hardware and dry-contact relay wiring.
