CCTV Camera Buying Guide for Offices in India

# CCTV Camera Buying Guide for Offices in India Setting up office surveillance for the first time — or replacing an aging system — comes with more decisions than most buyers expect: camera type, resolution, storage architecture, and whether you need a DVR or NVR system at all. This guide walks through each decision in order. ## Step 1: Choose Your Camera Type - **Dome cameras** — discreet, tamper-resistant housing; the standard choice for indoor office ceilings and reception areas. - **Bullet cameras** — visible, deterrent-focused; common for building entrances and outdoor perimeters. - **PTZ (pan-tilt-zoom)** — active monitoring of large open areas like warehouses or parking; higher cost, needs an operator or preset patrol routes to add real value. Most offices use a mix: dome cameras indoors, bullet cameras at entrances and perimeters. ## Step 2: Decide on Resolution Higher resolution means clearer footage — critical for identifying faces or reading number plates — but also larger storage requirements. Our [IP camera resolution guide](/blog/ip-camera-resolution-guide-what-buyers-should-know) covers this trade-off in detail; as a starting point, don't go below what's needed to clearly identify a person at your camera's typical distance from the subject. ## Step 3: Choose Analog (DVR) or IP (NVR) Architecture This is the biggest structural decision in the whole purchase. Analog cameras record through a **DVR**; IP cameras record through an **NVR** over your network, typically with PoE power. See our full [DVR vs NVR comparison](/blog/dvr-vs-nvr-which-surveillance-system-fits-your-business) if you're unsure which fits your building's existing wiring and your resolution needs — IP/NVR systems generally support significantly higher resolution and easier remote access. ## Step 4: Plan Storage - **Local storage** (DVR/NVR hard drive or endurance-rated microSD in camera) — the most common setup for office systems, sized against camera count, resolution, and how many days of footage you need to retain. - **Cloud/hybrid storage** — increasingly available, useful for off-site backup of critical footage, usually alongside local storage rather than replacing it. Retention requirements (how many days of footage you need on hand) directly drive storage capacity — decide this before sizing hardware, not after. ## Step 5: Confirm Network and Power Requirements (IP Systems) IP camera systems typically run over a **PoE switch**, which both powers the cameras and carries the video feed over one cable — simplifying installation versus running separate power to each camera location. Confirm your network switch has enough PoE ports and power budget for the camera count you're planning. ## A Simple Office CCTV Buying Checklist 1. Map camera locations — entrances, reception, stock areas, perimeter. 2. Choose camera type per location (dome indoors, bullet outdoors). 3. Decide DVR (analog) vs NVR (IP) based on wiring and resolution needs. 4. Confirm resolution against identification distance requirements. 5. Size storage against camera count, resolution, and retention days. 6. Confirm PoE switch capacity for IP deployments. 7. Plan installation — see our [CCTV installation guide](/blog/cctv-installation-for-small-businesses-what-to-expect) for what to expect. ## Frequently Asked Questions **How many CCTV cameras does a typical small office need?** It depends on entry points and floor layout — most small offices start with cameras covering the main entrance, reception, and any stock or server room, expanding from there based on floor plan. **Is IP (NVR) better than analog (DVR) for a new office installation?** For new installations, IP/NVR systems generally offer higher resolution and easier remote viewing, though analog/DVR can be more cost-effective when reusing existing coaxial wiring. See our [DVR vs NVR guide](/blog/dvr-vs-nvr-which-surveillance-system-fits-your-business) for the full comparison. **How long should CCTV footage be retained?** This depends on your business's compliance and operational needs — many offices retain 15–30 days as a baseline, adjusting storage capacity accordingly. **Do office CCTV systems need a dedicated network switch?** IP camera systems benefit from a dedicated or well-provisioned PoE switch to avoid contending with regular office network traffic and to simplify camera power delivery. --- **Planning an office CCTV installation?** [Request a Quote](/request-quote) with your floor plan and camera count, or read our [CCTV installation guide](/blog/cctv-installation-for-small-businesses-what-to-expect) to know what to expect during setup.
