Many installations use a mix.<\/p>\n<\/span>IP Camera vs Analogue Camera \u2014 The Resolution Revolution<\/span><\/h3>\nThis is the single most important technical decision in any CCTV camera installation<\/strong>.<\/p>\nAnalogue cameras<\/strong> (also called AHD, HDCVI, or HDTVI cameras) work with a DVR<\/strong> (Digital Video Recorder). They transmit video over coaxial cable. Modern HD analogue cameras deliver up to 8MP (4K) resolution and are significantly cheaper than IP systems.<\/p>\nIP cameras<\/strong> (Internet Protocol cameras) work with an NVR<\/strong> (Network Video Recorder). They transmit compressed digital video over CAT6 network cable or Wi-Fi. IP cameras offer higher image quality at equivalent resolutions, built-in analytics like face detection, better scalability, and easier long-distance runs using PoE switches.<\/p>\n\n\n\n| Factor<\/th>\n | Analogue (HD\/DVR)<\/th>\n | IP Camera (NVR)<\/th>\n<\/tr>\n<\/thead>\n | \n\n| Cabling<\/td>\n | Coaxial cable (RG59)<\/td>\n | CAT6 network cable<\/td>\n<\/tr>\n | \n| Resolution<\/td>\n | Up to 8MP \/ 4K<\/td>\n | Up to 12MP and beyond<\/td>\n<\/tr>\n | \n| Cost (per camera)<\/td>\n | Lower \u2014 \u20b91,500\u2013\u20b96,000<\/td>\n | Higher \u2014 \u20b93,000\u2013\u20b915,000+<\/td>\n<\/tr>\n | \n| Installation<\/td>\n | Simpler, familiar to most technicians<\/td>\n | Requires network knowledge<\/td>\n<\/tr>\n | \n| Scalability<\/td>\n | Limited by DVR channel count<\/td>\n | Highly scalable via network switches<\/td>\n<\/tr>\n | \n| Analytics<\/td>\n | Basic motion detection<\/td>\n | Face detection, people counting, line crossing<\/td>\n<\/tr>\n | \n| Best for<\/td>\n | Small offices (4\u201316 cameras), budget-conscious<\/td>\n | Large premises, multi-floor, future-proofing<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Practical advice:<\/strong> For a 4\u201316 camera system in a typical Delhi SME office, a quality HD analogue system with a Hikvision or CP Plus DVR delivers excellent results at significantly lower cost. For larger deployments (24+ cameras, multi-building, or where analytics matter), go IP with NVR.<\/p>\n<\/span>Wi-Fi Cameras \u2014 When They Work and When They Don’t<\/span><\/h3>\nWi-Fi CCTV cameras<\/strong> are popular because they seem to eliminate cabling headaches. In practice, they work well in limited, specific scenarios and fail in others.<\/p>\nWhere Wi-Fi cameras work:<\/strong><\/p>\n\n- Small home installations (2\u20134 cameras, strong Wi-Fi throughout)<\/li>\n
- Temporary monitoring needs<\/li>\n
- Locations where cable routing is genuinely impossible<\/li>\n
- Cloud-recording setups where local storage isn’t critical<\/li>\n<\/ul>\n
