Every Retired Camera Carries a Main SoC That Most Scrappers Ignore
Hikvision, Dahua and Uniview IPC cameras, legacy DVR/NVR units in communities and industrial parks, and the hundreds of millions of Safe City / smart-city surveillance points — at the heart of all of them sits a security main SoC. China's analog camera installed base numbers in the hundreds of millions, and between the analog-to-IP migration and aging DVR/NVR replacement, retired security main chips flow out by the tens of millions of units per year; a HiSilicon Hi3516CV500 (the mainstream 4MP IPC SoC) recycles at CNY 8-20, and the NVR SoC Hi3536DV100 reaches CNY 20-50. Most recyclers treat camera boards as generic e-scrap and sell the main SoC buried in the board by weight — the spread from CNY 3 to CNY 50 per tier means the savvy recycler makes several times more from the same batch of surveillance scrap.
Why Surveillance SoCs Deserve Their Own Dedicated Grade
The recycling value of security main chips rests on three structural drivers:
- A decade-scale refresh pipeline: the analog-to-IP migration is a ten-year retrofit program, and in 2026 more than half of analog sites are still pending; DVR/NVR units average 5-8 year service lives and first-phase Safe City hardware is entering centralized retirement — steady supply for years
- Repair-spare demand: surveillance runs on "replace the board when it fails," and discontinued models (the Hi3516A/C/D generation) carry standing 30-50% repair-channel premiums, with Hikvision/Dahua service channels as steady buyers
- The domestic-alternative dividend: after HiSilicon security chip supply swings, SigmaStar, Fullhan, Ingenic and Goke moved in to fill the gap — teardown next-gen IPC SoCs have clear demand from design houses and overseas white-label markets
Surveillance SoC value is not in the unit price — it's in tier-level sorting. IPC, NVR and AI main chips sold separately lift a batch by 50-80%.
Security Camera SoC Recycling Price Reference
Current reference prices for mainstream surveillance main chips (Reference Price (CNY) per chip, Q3 2026):
| Tier / application | Representative models | Reference Price (CNY) |
|---|
| Entry IPC SoC | HiSilicon Hi3516EV300, SigmaStar SSC335 | 3-10 |
| Mainstream IPC SoC | HiSilicon Hi3516CV500, SigmaStar SSC338Q | 8-20 |
| AI IPC SoC | HiSilicon Hi3516DV300, SigmaStar SSC339G | 15-40 |
| NVR SoC | HiSilicon Hi3536DV100, Hi3536C | 20-50 |
| Taiwan-scheme IPC SoC | Novatek NT98562, NT98566 | 8-25 |
| Domestic-scheme IPC SoC | Fullhan FH8858V200, Goke GK7205V300 | 5-12 |
| Entry domestic IPC SoC | Ingenic T31ZX, T31 series | 4-10 |
Note: These are Q3 2026 reference ranges. Chips with crisp markings, harvested from identifiable brand cameras (Hikvision/Dahua/Uniview), and shipped bundled with their mating DDR memory command the top of these ranges and often more.
Identification & Grading: Four Moves That Set the Quote
- Read the marking: Hi3516EV300/CV500/DV300 look alike and are pin-compatible while grading several tiers apart — verify with a loupe; same for SigmaStar SSC335/338Q/339G
- Check package & pairing: IPC SoCs are mostly BGA and most need DDR (DDR3/DDR4) to function; SoC+DRAM bundles sell for more, so keep the surrounding circuitry when harvesting at board level
- Verify EOL status: older Hi3516A/C models are discontinued with clear repair-channel spare premiums; main boards from identifiable brands (carrying original serial numbers) close at higher prices
- Data & confidentiality: camera storage and onboard flash hold video and account credentials — offering erasure/destruction is the precondition for enterprise deals; classified surveillance-channel material is handled per compliance rules
Mixing surveillance main chips into generic logic scrap gives the CCTV repair market's spare budget away at scrap prices — tier-level sorting is where the margin lives.
Who Buys Teardown Surveillance SoCs?
- Security repair & refurbishers: DVR/NVR board replacement and used-unit refurbishment for export; discontinued-model main chips face rigid demand at steady volume
- Design houses & white-label makers: overseas white-label IPC schemes need low-cost SoC+DRAM kits, and SigmaStar/Fullhan/Novatek parts turn over fast
- Overseas security markets: Southeast Asia, the Middle East and Latin America have strong demand for used surveillance units and boards — mind export compliance and trademarks
- Disassembly & material recyclers: BGA main chips are reballed into remanufacturing channels, sharing the sorting line with automotive MCUs
Advice for Recyclers
- Grade them separately, never with generic logic: mixing with standard logic chips prices the lot at the lowest tier; sorting lifts a batch by 50-80%
- Segregate by tier: entry/mainstream/AI IPC, NVR and domestic-scheme parts apart; check EOL pricing before quoting
- Keep origin records: which camera brand and which project class (Safe City, campus, retail) — traceable parts carry clear premiums
- Offer data destruction: proactively provide video-data erasure/destruction reports — the core edge for winning enterprise volume
- Keep ESD discipline: BGA main chips are static-sensitive; anti-static bags and moisture-barrier storage are basic practice to protect the whole lot
