The most common CCTV regret we see isn't a bad camera brand — it's a system that was never planned properly. Too few cameras to cover the actual entry points, a DVR with only 7 days of storage when the footage was needed on day 10, or wireless cameras that drop out right when the Wi-Fi gets busy. This guide walks through every decision in plain language, in the order you should actually make them, so your first CCTV system is the right one.
Step 1: Plan Your Coverage Before Choosing Any Camera
Start by walking your property and listing every point someone could enter, or every area you actually need to review later — not just "more cameras is better". A camera pointed at an empty wall is a wasted channel.
- Main gate and entrance — almost always the highest priority.
- Parking area or two-wheeler stand.
- Cash counter or reception (for shops and offices).
- Backyard, terrace access, or any secondary entry.
- Warehouse aisles or stock rooms, if applicable.
| Property type | Typical camera count | Priority zones |
|---|---|---|
| 1–2 BHK apartment | 2–4 cameras | Main door, balcony/entry, living area |
| Independent house | 4–6 cameras | Gate, parking, front door, backyard |
| Small shop or showroom | 4–6 cameras | Entrance, cash counter, aisles, back exit |
| Office (small-medium) | 6–10 cameras | Entrance, reception, floor coverage, server/cash room |
| Warehouse or large business | 10–16+ cameras | Gate, loading bay, aisles, perimeter, office block |
Step 2: Choose the Right Resolution
Resolution decides how much detail you'll actually see when you zoom into footage later — this matters far more for identifying a face or number plate than most people expect.
- 2MP (1080p) — a reasonable minimum today; fine for general area coverage and short distances.
- 4MP — the best value point for most homes and shops in 2026; noticeably clearer faces and plates, modest storage cost increase.
- 8MP (4K) — worth it for wide areas viewed from a single camera, like a large gate, parking lot or warehouse floor, where you need to zoom into a small section after the fact.
Step 3: Pick the Camera Type for Each Location
| Camera type | Best for | Trade-off |
|---|---|---|
| Dome camera | Indoor areas, reception, shop floors | Discreet and vandal-resistant, but a fixed, narrower view |
| Bullet camera | Entrances, gates, long-distance outdoor views | Very visible (a deterrent), better range, needs weatherproofing |
| PTZ (pan-tilt-zoom) | Large open areas — parking lots, warehouses | Covers a wide area with one unit, but higher cost, one spot at a time unless on auto-patrol |
| Wi-Fi / smart camera | Quick indoor setup, rented spaces, single rooms | Easiest to install, but depends on Wi-Fi reliability and usually cloud storage fees |
Step 4: Wired or Wireless?
For anything beyond one or two indoor cameras, wired is the more dependable choice — no battery to recharge, no dropped connection when the router restarts, and no interference from other 2.4GHz devices. Wireless cameras are genuinely useful for renters, a single extra room, or a spot where cabling isn't possible, but they shouldn't be your only coverage for a main entrance or cash area.
Step 5: Night Vision That Actually Works
Almost all cameras claim "night vision", but range and quality vary widely. Look for a stated infrared range of at least 20–30 metres for outdoor gate/parking cameras, and consider color night vision cameras for entrances, where identifying clothing or a vehicle color matters more than for a general area camera.
Step 6: Understand Your Storage Options
This is the step most first-time buyers skip, and the one that causes the most regret later — footage you need is often only discovered missing after the fact.
- DVR (with analog/HD-CVI cameras) vs NVR (with IP cameras) — NVR systems generally give sharper footage and easier remote access; DVR setups are often more budget-friendly for basic coverage.
- Local hard drive storage — a one-time cost, footage stays on-site, but is vulnerable if the recorder itself is stolen or damaged.
- Cloud storage — footage stays safe even if the recorder is tampered with, usually at a recurring subscription cost.
- Retention period — as a rule of thumb, more cameras and higher resolution both reduce how many days a given hard drive size will hold; ask your installer to size the drive to at least 15–30 days of footage, not just what's cheapest today.
Step 7: Power — PoE Makes Installation Cleaner
Power over Ethernet (PoE) cameras carry both power and data over a single cable, which means fewer wires, fewer points of failure, and an easier installation — worth asking for specifically when you're wiring a new location from scratch.
Step 8: Remote Viewing on Your Phone
Nearly every modern DVR/NVR supports a mobile app for live viewing and playback from anywhere, but the setup quality varies — a properly configured system should notify you of motion in real time and let you scrub back through footage smoothly, not just show a frozen preview.
A Note on Brands
CP Plus, Hikvision and Dahua are the three brands we install most often across Bangalore homes and businesses, each with slightly different strengths in budget, image quality and app experience — read our dedicated brand pages for CP Plus CCTV installation, Hikvision CCTV installation and Dahua CCTV installation for a closer look at each, or let us recommend one based on your specific coverage plan.
Budget Tiers at a Glance
| Tier | Setup | Good for |
|---|---|---|
| Essential | 4 x 2MP dome/bullet cameras, DVR, 15-day local storage | Small apartments and homes on a budget |
| Recommended | 6–8 x 4MP cameras (mixed dome/bullet), NVR, 30-day storage, mobile app | Most homes, shops and small offices |
| Business | 8–16+ cameras with PTZ where needed, NVR with RAID or cloud backup | Warehouses, larger offices, multi-floor businesses |
Installation and Maintenance Tips
- Mount outdoor cameras under an eave or sunshade — direct rain exposure shortens their lifespan even on "weatherproof" models.
- Keep cabling inside conduit where possible; exposed cables are the most common cause of camera downtime after 1–2 monsoons.
- Clean camera lenses every few months — dust and cobwebs quietly ruin night footage long before they're visible in daylight.
- Test playback (not just the live view) every few weeks — a system can silently stop recording while the live feed still looks fine.
A quick legal note for India
Keep camera angles focused on your own property — avoid pointing cameras directly into a neighbour's windows or private space, and inform employees where workplace cameras are installed. This avoids privacy disputes and keeps your installation on solid legal footing.
