Best for: Tech-savvy users, smart home enthusiasts, those wanting remote monitoring.
Multi-Unit Apartment Systems
Designed for apartment buildings with multiple indoor stations connected to common outdoor panels. They feature individual unit calling, access control integration, and centralized visitor management. Installation requires professional setup and building-wide coordination.
Best for: Apartment complexes, gated communities, commercial buildings.
Essential Features to Consider
Video Quality: Minimum 720p resolution recommended; 1080p ideal for clear facial recognition. Night vision with IR LEDs ensures visibility in low-light conditions (at least 3-5 meters range).
Two-Way Audio: Clear communication is crucial. Look for noise cancellation and echo reduction features. Test audio quality before final installation.
Unlocking Capability: Electric door lock integration allows remote access for trusted visitors. Ensure compatibility with your existing lock or plan to upgrade.
Recording Options: Local storage (SD card up to 128GB) or cloud storage. Consider recording continuous video or motion-triggered clips only to save storage space.
Weather Resistance: Outdoor units need IP65 rating minimum for Indian weather conditions. IP66 or IP67 better for areas with heavy monsoons.
Power Supply: Choose between AC powered (stable, no battery worries), battery powered (flexible placement but requires charging), or PoE powered (single cable for power and data).
Installation Requirements
Tools Needed
Basic toolkit including screwdriver set (Phillips and flathead), drill machine with masonry bits, wire stripper and cutter, multimeter for testing, cable clips and cable ties, silicone sealant for weatherproofing, and pencil for marking.
Materials Required
Video door phone kit (outdoor and indoor units), cables (if wired system—typically 4-6 core cable), mounting bracket and screws, power adapter or PoE injector, electric door lock (if adding remote unlock), junction box for cable connections, and cable conduit or trunking.
Step-by-Step Installation Guide
Step 1: Choose Installation Location
Select a location for the outdoor unit at chest to eye level (approximately 1.5-1.7 meters) with clear view of visitor’s face. Ensure weather protection (covered porch ideal) and proximity to power source if AC powered. Position away from direct sunlight to prevent glare and near your WiFi router for wireless systems (within 10-15 meters).
For indoor monitor, install in a convenient location like living room or bedroom at comfortable viewing height (1.4-1.5 meters). Ensure the location allows easy cable routing from outdoor unit.
Step 2: Install Outdoor Unit
Mark drilling points using the mounting bracket as template. Drill holes using appropriate masonry bit (typically 6-8mm). Insert wall anchors firmly and attach mounting bracket securely. Connect wires before mounting the outdoor unit if using wired system.
Apply silicone sealant around cable entry points to prevent water ingress during monsoons. Mount the outdoor camera unit onto bracket and secure with provided screws. Ensure the camera angle captures visitor’s face clearly.
Step 3: Run Cables (For Wired Systems)
Plan the cable route from outdoor to indoor unit avoiding electrical wiring to prevent interference. Use wall chasing for concealed installation or cable trunking for surface mounting. For multi-story buildings, run cables through existing conduits or along exterior walls.
Use 4-core cable minimum (power, audio, video, ground) or 6-core for systems with additional features. Leave 15-20cm extra cable at both ends for connections. Secure cables with clips every 30-40cm to prevent sagging.
Step 4: Install Indoor Monitor
Mount the indoor monitor bracket at comfortable viewing height. Connect cables following color coding: red (positive power), black (negative power), yellow (video signal), white (audio). Use terminal blocks for secure connections.
For wireless systems, simply plug in the monitor and pair with outdoor unit following manufacturer’s instructions. Most systems use button-press pairing within first 30 seconds of powering on.
Step 5: Power Connection
For AC-powered systems, connect the power adapter to indoor monitor. Ensure voltage matches specifications (typically 12V DC or 24V AC). For PoE systems, connect to PoE switch or injector. Battery-powered units need full charging before first use (4-6 hours typically).
Test power indicator lights to confirm proper connection. Indoor monitor should light up when powered correctly.
Step 6: System Configuration
Access settings menu on indoor monitor using provided controls. Set brightness and contrast for optimal viewing, adjust volume for doorbell chime and intercom, configure motion detection sensitivity (if available), and set recording preferences (continuous or event-based).
For WiFi systems, connect to your home network through settings menu. Enter WiFi password and wait for confirmation. Download smartphone app and create account for remote access features.
Step 7: Test All Functions
Press doorbell button and verify chime sounds and video displays. Test two-way audio quality—speak clearly and check for delays or distortion. If equipped with unlock feature, test electric lock operation. Verify night vision activates in low light and check motion detection alerts trigger correctly.
Test from different angles to ensure camera coverage is adequate. Adjust camera angle if needed to capture visitor faces properly.
Wireless System Setup
Wireless systems require additional configuration steps beyond basic installation. Connect outdoor unit to WiFi following app instructions—use 2.4 GHz band as outdoor units typically don’t support 5 GHz. Position unit within 10-15 meters of router for stable connection.
Enable push notifications for doorbell press and motion detection events. Configure privacy zones to exclude public areas from recording. Set up user accounts for family members with appropriate access levels. Link to smart home systems like Alexa or Google Home if supported.
