Not sure how many cameras to install at home? Our CCTV experts walk you through every room, entry point, and blind-spot calculation so you get full coverage without overspending.

When apartment residents ask about CCTV, they're usually asking about one of two very different things:
The requirements, costs, technology choices, and legal considerations differ significantly between these two. This guide covers both, drawing on CCTVPROS's installation experience across apartment complexes in Kottayam, Changanacherry, and Pala.
Every apartment complex in Kerala should have CCTV coverage at these minimum points:
Kerala Police's Safe City initiative includes apartment complexes in high-density areas of Kottayam, and buildings registered under the Kerala Apartment Ownership Act are advised to maintain functional CCTV with 30-day retention.
| Building Size | Cameras Needed | Storage (30-day) | Approx. Cost (Installed) |
|---|---|---|---|
| 4–6 flats (small building) | 6–8 | 1–2 TB | ₹25,000–40,000 |
| 12–24 flats (medium complex) | 12–16 | 2–4 TB | ₹55,000–85,000 |
| 50+ flats (large complex) | 24–40 | 6–8 TB | ₹1,20,000–2,50,000 |
Society CCTV is typically funded from the maintenance corpus and maintained under an AMC (Annual Maintenance Contract). CCTVPROS offers building society AMC plans starting from ₹4,000/year for small buildings.
ANPR (Automatic Number Plate Recognition) cameras automatically read and log vehicle number plates as they enter and exit. For larger apartment complexes, this is highly recommended because it: prevents unauthorised vehicle entry, creates a permanent entry log, and enables fast police cooperation in the event of a crime. Hikvision's DeepinView ANPR cameras compatible with iVMS-4200 software are our standard recommendation. The premium over a standard camera is approximately ₹2,000–3,000 per unit.
Within your own flat, you can install CCTV cameras wherever you choose — inside rooms, facing your front door from inside, covering your balcony. There are three legal boundaries:
For most flat owners in Kerala, we recommend a 2-camera wireless IP solution:
These cameras connect to your home Wi-Fi and record to a microSD card (up to 256 GB) or to cloud storage — no DVR or NVR required. Live view and alerts are managed through Hik-Connect (Hikvision) or DMSS (Dahua).
Total cost for 2 wireless cameras with installation in Kottayam: approximately ₹8,000–14,000 depending on camera models.
Renters have limited options since landlords often prohibit wall modifications. However, these approaches work without permanent fixtures:
These options mean even renters can have effective flat security. When you move, the cameras move with you.
In many older Kottayam apartment buildings, the housing society may not have installed CCTV at all, or existing cameras may be years old and non-functional. Here's a practical approach:
CCTVPROS has successfully installed society CCTV systems for multiple apartment complexes in Kottayam and Changanacherry. We provide a complete turnkey solution including hardware, cabling, software configuration, and staff training for the security guard or watchman.

Yes, you can install cameras anywhere inside your own flat. Cameras facing your front door from inside or covering your balcony are also allowed. Cameras in common corridors require housing society permission. Cameras in areas where domestic workers are present require the workers to be informed.
Yes, using wireless cameras that don't require wall drilling. Video doorbells, desk-mount indoor cameras, and magnetic-mount cameras are all renter-friendly options. For cameras requiring wall mounting, discuss with your landlord — most agree when cameras are clearly inside the rented unit.
A small building of 4–6 flats needs 6–8 cameras covering gate, lobby, lift, and parking. A medium complex of 12–24 flats needs 12–16 cameras. Minimum mandatory coverage is gate, building lobby, lift interior, and parking area.
ANPR (Automatic Number Plate Recognition) cameras automatically read vehicle number plates at the gate and log them. For complexes with 20+ flats and active vehicle movement, ANPR significantly improves security and incident resolution. The premium over a standard gate camera is ₹2,000–3,000.
Kerala Police recommends a minimum of 30 days retention for commercial and residential complex CCTV. For a 12-camera system at 4MP recording 24/7, this requires approximately 2–3 TB of storage. Use surveillance-grade hard drives (WD Purple or Seagate SkyHawk).
A complete system for a small 4–6 flat building (6–8 cameras, DVR, hard disk, installation) costs approximately ₹25,000–40,000. Medium complexes (12–16 cameras) range from ₹55,000–85,000. CCTVPROS offers free society-level site surveys and detailed quotes.
The Hikvision 2MP Wi-Fi dome with 355° rotation is ideal for indoor flat use (₹2,999). For outside the flat door in the corridor, the Hikvision 2MP Wi-Fi outdoor bullet (₹3,499) provides weatherproof operation. Both connect to Wi-Fi with no DVR needed.
