“Keep 90 days” sounds simple until you do the math: 20 cameras at 2 Mbps, even with motion-triggered recording, come to about 4.4 TB a month and 13 TB a quarter. Let’s see where the numbers come from and how to store it for less.
Who requires what
| Who | Retention | Why |
|---|---|---|
| Wildberries pickup points | 90 days | order disputes, penalties |
| Yandex Market, Ozon pickup points | 100 days | claim reviews |
| Banks, currency exchange offices | 90 to 180 days | regulatory requirements |
| Shopping malls, parking lots | 30–60 days | incidents, insurance claims |
| Manufacturing, warehouses | 30 days, longer for “critical” areas | shortages, workplace safety |
How to calculate the size
The formula: camera bitrate × number of cameras × seconds per day × days ÷ 8. A Full HD camera at 2 Mbps produces about 21 GB per day with continuous recording. With motion-triggered recording in a typical store, it’s 30–50% of that.
| Cameras | 30 days | 90 days | 100 days |
|---|---|---|---|
| 4 | 2.5 TB | 7.5 TB | 8.4 TB |
| 8 | 5 TB | 15 TB | 17 TB |
| 16 | 10 TB | 30 TB | 34 TB |
| 32 | 20 TB | 60 TB | 67 TB |
These figures are for continuous recording; with motion-triggered recording, divide by two or three.
Why not just an NVR with big disks
- A 60 TB recorder means 4–8 disks, RAID, noise and heat in the back room, and the risk of it being stolen along with the recordings.
- Disks fail; lose two in a RAID5 and the entire archive is gone — exactly when you need it for a dispute.
- You can’t expand it, only replace it — and buy everything again.
How it works in the cloud
Cameras record on motion directly to the MyCloud cloud or via Bridge — if the internet drops, recording continues locally and is uploaded once the connection is restored. The archive is stored in the data center in Tashkent with disk redundancy; capacity can be changed at any time. If recordings must be kept for a year or longer (banks, schools, government clients), footage older than the hot period moves automatically to a “cold” archive for 1–3 years at 2 UZS per GB per day.
Price
The price per GB per day depends on archive depth: 7–30 days — 10 UZS, 60 days — 8, 90–100 days — 7, 180 days — 6, 365 days — 5; the cold archive (1–3 years) — on request. A pickup point with 4 Full HD cameras and a 100-day archive with motion-triggered recording takes about 2.9 TB (4 × 21 GB × 0.35 × 100 days) — about 20 600 UZS per day, or roughly 620 000 UZS per month.
