How Many CCTV Cameras Do You Really Need? A Room-by-Room Guide for Chennai Homes & Businesses

One of the most common questions we get at SBM Technologies is: "How many cameras do I actually need?" The answer depends on your property type, size, and the blind spots you want to cover. This guide helps you figure it out — room by room.

Why Camera Count Matters

Installing too few cameras leaves dangerous blind spots. Installing too many without a plan wastes your budget. The sweet spot is a strategic layout tailored to your home or business in Chennai.

Room-by-Room Guide for Homes

Front Door & Main Gate: 1 camera minimum. Use a wide-angle HD camera or a 360 degree Wi-Fi camera like the Qubo Smart Cam 2K to cover the full entry zone.

Living Room / Hall: 1 camera covering the main area. Position it in a corner for maximum field of view.

Back Door / Garage: 1 camera per entry point. Night vision is essential for these spots.

Parking / Driveway: 1-2 bullet cameras depending on driveway length. Consider a Solar Camera for outdoor areas with no power point nearby.

Minimum for a 2BHK home: 4 cameras. Recommended for a 3BHK villa: 6-8 cameras.

For Businesses & Offices in Chennai

Reception / Entry: 1-2 cameras. Cash Counter / Billing Area: 1 camera (high-resolution, minimum 4MP). Warehouse / Storage Room: 1-2 cameras per large bay. Server Room: 1 dedicated IP camera. Parking / External Perimeter: 2-4 cameras.

Minimum for a small shop: 4 cameras. Recommended for a medium office: 8-16 cameras.

Which CCTV Type Is Right for Each Zone?

HD Bullet Camera (CP Plus, Hikvision): Best for long corridors, parking, and outdoor perimeters. We stock 30m and 60m IR range models starting at Rs 3,910.

IP Dome Camera: Best for indoor areas like reception, server rooms, and shops. Discreet and wide-angle coverage.

Wi-Fi / SIM Cameras: Perfect for remote sites, farmhouses, and locations without DVR/NVR infrastructure.

Solar Cameras: Ideal for gate areas and outdoor locations with no electricity access.

What About DVR or NVR?

The number of cameras determines your recorder: 4 cameras needs a 4-channel DVR, 8 cameras needs an 8-channel DVR, and 16+ cameras needs a 16-channel DVR or NVR for IP systems. SBM Technologies stocks CP Plus, Hikvision, and IMOU DVRs/NVRs with free 1TB hard disk options.
