Three places footage can live
Every CCTV camera has to store its video somewhere. Most business and home systems in India record to a network video recorder (NVR) with hard disks on site. Many Wi-Fi cameras record to a memory card inside the camera. And a growing number of systems upload some or all footage to cloud storage on the internet. Each has strengths, and the right answer for most sites in 2026 is a mix.
Side-by-side comparison
| Factor | NVR (local) | SD card in camera | Cloud |
|---|---|---|---|
| Retention | 30–90 days typical, set by disk size | Days to a couple of weeks | Set by subscription plan |
| Running cost | Disk replacement every few years | Card replacement | Monthly fee per camera |
| Internet needed | Only for remote viewing | Only for remote viewing | Constant upload bandwidth |
| If thieves steal the recorder | Footage lost unless backed up | Footage lost with the camera | Footage safe |
| Picture quality | Full resolution, continuous | Full resolution, limited time | Often reduced or event-only to save bandwidth |
| Best for | Most businesses and homes | Single cameras and Wi-Fi models | Remote sites, high-risk evidence, multi-branch |
The bandwidth problem
Continuous cloud recording needs steady upload speed. A single 4MP camera using H.265 typically needs around 1 to 2 Mbps of upload to stream continuously at good quality, so 16 cameras can need 20 Mbps or more of upload all day — more than many business broadband plans reliably deliver, and a burden on a shared office connection. That is why most cloud CCTV plans record only on events, at lower resolution, or for a few selected cameras.
H.265 vs H.264 compression →When local recording is right
- You need 30 days or more of continuous, full-resolution footage — as the Karnataka Public Safety Act requires for covered premises.
- You have many cameras and limited upload speed.
- You want no monthly fees.
- Privacy policy prefers footage to stay on premises.
When cloud is worth paying for
- Remote or unmanned sites where the recorder itself could be stolen or damaged.
- Cash counters, jewellery displays and main entrances where losing evidence is not acceptable.
- Multi-branch businesses that want central access without opening ports or VPNs.
- Homes where a single Wi-Fi camera has no NVR at all.
The hybrid approach we recommend
For most sites, record every camera continuously on an NVR in a locked, ventilated place on a UPS, and add cloud backup only for the few cameras that matter most — entrance, cash counter, server room — or upload event clips. If burglars take the NVR, the critical moments are already off-site. Some NVRs can also copy footage to a network storage device in a different room, which protects against theft at lower cost.
Privacy and security of cloud footage
Footage in the cloud is personal data under the DPDP Act, so know where it is stored, who can access it, and how long it is kept. Use strong unique passwords and two-factor login on the cloud account, limit who has access, and choose providers that encrypt data in transit and at rest. Cheap cloud cameras with unknown back-ends are a real risk.

Our CCTV installation service →Quick answers
Is cloud CCTV recording better than an NVR?+
Not for most sites. An NVR stores more footage at full quality with no monthly fee. Cloud is best as a backup for key cameras or for remote sites.
How much internet does cloud CCTV need?+
Roughly 1 to 2 Mbps of upload per 4MP camera for continuous recording, less for event-only uploads.
What if thieves steal my NVR?+
The footage goes with it unless it is backed up to the cloud or another device. Lock the NVR away and back up key cameras.
Is cloud CCTV footage private?+
Only as private as the provider and your account security. Use strong passwords, two-factor login and a reputable provider.
