The short answer
HD analog cameras with a DVR are the budget choice and work well for homes and small shops with up to around 8 cameras. IP cameras with an NVR give better images, more features and scale far better — they are the right choice for offices, apartments, factories and warehouses.
SightShield installs IP camera systems only. Every camera we supply records to an NVR over PoE, and every model we quote is certified for sale in India under the government’s CCTV security testing rules.
Side-by-side comparison
| HD analog (DVR) | IP (NVR) | |
|---|---|---|
| Cable | Coaxial cable + separate power | Network cable carrying power (PoE) and video |
| Typical resolution | 2MP–5MP | 2MP–8MP (4K) and above |
| Image detail | Good | Sharper, especially for faces and distant areas |
| Cost | Lower upfront | Higher upfront, lower cost per camera at scale |
| Cable distance | Long runs on coax | 100 m per run; fibre or switches for longer |
| Smart features | Basic motion detection | Line-crossing, intrusion alerts, better search |
| Expansion | Limited by DVR channels | Add cameras on the network as you grow |
| Best for | Homes, small shops | Offices, apartments, factories, warehouses |
When HD analog makes sense
If you have a home or a small shop, need 4–8 cameras and want to keep the cost low, HD analog is a sensible choice. It is also a good way to upgrade an old analog system, because existing coaxial cables can often be reused.
We no longer supply analog systems. If budget is the concern, an entry-level IP kit — 2MP or 4MP cameras with a 4- or 8-channel PoE NVR — narrows the price gap considerably, and it can grow with you instead of hitting the DVR’s channel limit.
When to choose IP
Choose IP when you need sharper images, more than 8–16 cameras, cameras spread across several buildings, or smart alerts like intrusion and line-crossing. Apartments, offices and factories almost always end up on IP, with cameras on their own network so they never slow down office systems.
What IP means for each type of property
| Property | Why IP fits |
|---|---|
| Homes and villas | Sharper gate images, person alerts on the phone, easy to add cameras later |
| Shops and showrooms | Counter detail, POS overlay, people counting on some models |
| Apartments | Scales to many cameras across blocks over network switches and fibre |
| Offices | Shares structured cabling with IT; separate VLAN for security |
| Factories and warehouses | Long runs via switches and fibre, perimeter analytics, number plates |
Upgrading from an old analog system
If you already have an analog system, moving to IP is usually done by replacing cameras and the recorder and pulling network cable through existing conduits. Large systems can be upgraded in stages, starting with the gate and entrances.
Upgrading a DVR system to IP →Brands
CP Plus, PRAMA, Honeywell and Hikvision all make both HD analog and IP ranges; we supply their IP ranges only. The right model depends on the spot — wide angle for a compound, higher resolution for a gate, colour-night for poorly lit areas.
CCTV installation services →Quick answers
Is IP CCTV better than HD analog?+
IP gives sharper images, smart alerts and easier expansion. HD analog is cheaper and fine for homes and small shops with a few cameras.
Can I reuse my old CCTV cables?+
Existing coaxial cables can often be reused with HD analog cameras. Moving to IP usually needs new network cabling. When we upgrade an old analog system to IP, we survey the existing routes and reuse conduits wherever possible.
Does IP CCTV need internet?+
No. IP cameras record locally to the NVR. Internet is only needed to view cameras remotely on your phone.
Does SightShield install HD analog CCTV?+
No. We install IP camera systems with NVRs only, using models certified for sale in India. We can replace an existing analog DVR system with IP, reusing conduits where possible.
Are IP cameras harder to install?+
Not for a professional installer. One cable per camera carries power and video, which often makes installation neater.
Do IP cameras need to be certified in India?+
Yes. Since April 2026, IP camera models sold in India must be certified under the government’s Essential Requirements testing.
