The same headline spec — 4MP, PoE, ONVIF, IP66, metal housing — can be quoted at USD 12 in China, and it can be quoted at USD 48. Very little of that spread is factory profit. Almost all of it sits in four places you cannot see on the quotation sheet: the actual size of the image sensor, the lens and IR board, what codecs the SoC can actually run, and whose name the FCC ID or CE report is registered under.
This article is not a product primer. It is a set of buying actions: how to tell the three supplier types apart, the six checks to run during screening, what the cost structure of a 1,000-unit order looks like, which parameters must be written into the quotation, how to verify US and EU certification on the spot, and the five pitfalls buyers fall into most often.
Separate the Three Supplier Types Before You Talk Price
Putting all three into one comparison table is the most common first mistake — their capacity, certification capability and markup models are completely different.
| Supplier type | Typical signs | Strengths | Risks | Best for |
|---|---|---|---|---|
| Original manufacturer / solution provider (own SMT line and firmware team) | Can quote sensor model, SoC model, firmware version; has burn-in room and test stations | Traceable parameters, can do ODM, certification filed under their own entity | Higher MOQ, firm payment terms | 500+ units, own brand or long-term projects |
| Private-label house (bought-in module + own housing or silk print) | Fast quotes, wide model range, small batches accepted | Flexible, works from a few dozen units | Sensor and SoC often substituted, certification may be borrowed | First trial order, small e-commerce volumes |
| Trading company re-selling | Quotes anything, lowest price | Easy communication | Cannot trace problems back to a line; inspection and liability chain breaks | Very low volume, non-project use |
The test is simple: a supplier willing to show you the bare board — not the finished unit — usually solders its own boards. A “factory” that only offers product photos and a narrated video is most likely a private-label house or a trading company. That does not make them unusable, but you negotiate price on private-label terms, not manufacturer terms.
Six Screening Checks
Run these in order. The first two take 10 minutes and eliminate half the candidates.
| # | What to check | How to check it (concrete action) | Reject signals |
|---|---|---|---|
| 1 | Legal entity | Look up the Unified Social Credit Code on the National Enterprise Credit Information Publicity System: operating anomalies, administrative penalties, equity changes, registered capital | Incorporated within 1 year, registered capital of RMB 100,000, business scope with no security-related item |
| 2 | Factory or trader | Ask for time-stamped line video: SMT line, assembly line, burn-in room; then 3 months of incoming material records | Only showroom and packing area footage; refuses to film the SMT line |
| 3 | Sensor and SoC traceability | Ask for sensor part number + SoC model + incoming inspection records; open one unit and read the markings | Answers like “branded chip” or “4MP HD” that cannot be verified |
| 4 | Protocol conformance | Ask for the ONVIF Profile (S / G / T) declaration, and have a sample unit sent to test against your NVR / VMS | Private protocol only, requires a specific client to view |
| 5 | Certification authenticity | Check the FCC ID against the FCC grantee database for grantee and model match; for CE, check the DoC and whether the notified laboratory is within EU recognition | Report model does not match the model being sold; borrowed FCC ID |
| 6 | Capacity and lead time | Ask monthly capacity, current scheduling, sensor and SoC stock, and the fallback plan if a key component runs short | Lead time answered as “we can ship anytime” with no scheduling cycle |
Checks 3 and 5 are the two steps buyers most often skip and most often regret. For what to look at when you open a unit and how burn-in testing is run, see our eight on-site tests during a CCTV factory audit and BOQ-based quality control for ICT equipment.
Cost Structure at 1,000 Units: Where the Money Goes
The same spec can differ 2-3x, and the difference concentrates in the table below. Take a 4MP metal-housing PoE bullet at 1,000-unit volume:
| Stage | Cost share | What to watch when buying |
|---|---|---|
| Image sensor + SoC | 35-45% | 1/2.8” and 1/3” are both sold as 4MP, but night performance makes them two different products; the SoC decides H.265 and on-camera AI capability |
| Lens + IR-CUT + IR board | 10-15% | Lens aperture (F1.4 vs F2.0), IR LED count and wavelength (850nm / 940nm differ in covertness) |
| Housing (die-cast aluminium / plastic) + seals | 10-15% | Plastic housing is 20-30% cheaper but weaker on IK impact and heat dissipation; not worth saving on for outdoor projects |
| PCBA, power and connectors | 8-12% | Whether surge and lightning protection components are actually populated (the most failure-prone point on outdoor poles) |
| Firmware and protocol work | 5-10% | ONVIF compatibility, whether AI runs on the camera or the recorder, whether it is locked to a vendor cloud |
| Packaging and accessories | 3-5% | Whether waterproof connectors, brackets and screws are included in the unit price |
| Certification and test amortisation | 2-5% | Whose entity files the FCC ID decides whether you can sell under your own brand |
| Factory margin | 10-20% | A margin below 10% usually means something was substituted |
As price anchors, common FOB ranges at 1-10 unit quantities on public sourcing platforms are roughly:
| Camera type | Common FOB range (1-10 unit quantity basis) |
|---|---|
| 2-4MP plastic dome / bullet | About US$8-20 |
| 4MP metal-housing PoE (1/2.8” sensor) | About US$20-45 |
| 5-8MP with human / vehicle detection | About US$35-90 |
| Outdoor PTZ (20-25x optical zoom) | About US$60-280 |
| Licence-plate recognition (LPR) units | About US$200-350 |
Use this table only to judge whether a quote is an outlier, not as a basis for pricing: small-order public prices run 10-25% above volume prices, and a quote clearly below the bottom of the range almost always has the sensor, the housing or the certification swapped out.
Ten Items That Must Be Written Into the Quotation
Every argument you cannot win at acceptance traces back to the quotation. A CCTV RFQ should specify at least:
- Image sensor: size (1/2.8” / 1/3”) + resolution + minimum illumination;
- SoC model + supported codecs (H.265 main / sub / third stream);
- Lens: focal length, aperture, fixed or motorised varifocal;
- IR: LED count, wavelength, effective distance;
- Power: PoE class (802.3af 15.4 W / 802.3at 30 W) and maximum power draw;
- Ingress protection: IP66 / IP67 and IK rating (IK10 = 20 joules, not 10 joules);
- Protocol: ONVIF Profile S / G / T, RTSP URL format, GB28181 support;
- Housing material and colour;
- Certification: FCC ID, CE report number and laboratory, and whether the certificate holder is the factory or you;
- Packaging: units per carton, carton size and gross weight, whether waterproof connectors are included.
The most common failure on item 5: the quote says 802.3af, but with full IR plus PTZ movement the unit exceeds 12.95 W and the PoE switch port reboots. For PoE budgeting and how vendors understate power, see the 24-port PoE switch sourcing guide. How to verify IP / IK ratings on site is a standing item on our factory audit checklist.
Exporting to the US and EU: How to Verify Certification On the Spot
| Market | Documents needed | Where fakes concentrate | How to verify |
|---|---|---|---|
| US | FCC ID (Part 15C for radio models, Part 15B for wired-only models) | Borrowed FCC ID, report model not matching the model sold | Search the FCC grantee database by grantee + model and confirm the applicant matches the factory |
| US government procurement | NDAA compliance statement | Verbal supplier promise | Check the final manufacturer including subsidiaries and associated brands against the prohibited list; private label does not change manufacturer attribution |
| EU | Wireless models: RED 2014/53/EU; wired models: EMC 2014/30/EU; plus LVD and ErP if an adapter is supplied | DoC with no test report, laboratory outside EU recognition | Ask for the DoC plus a test report from a notified laboratory, and match report number to model |
| General | RoHS / REACH declarations of conformity | Self-declaration of “environmentally friendly material” | Ask for third-party test reports, testing the plastics and cable most likely to exceed limits |
| System compatibility | ONVIF conformance | Claims ONVIF but private extensions lock functions | Check the model on the ONVIF conformance product list and run a live test against your VMS |
One point on NDAA must be clear: private label does not change manufacturer attribution. If the imaging solution and firmware come from a vendor on the US prohibited list, renaming the brand and changing the housing does not make it compliant. For US projects — especially government, schools, airports and utilities — ask who owns the SoC and firmware at the RFQ stage, not at inspection.

MOQ, Sampling and Payment Terms
| Item | Common terms | Negotiation points |
|---|---|---|
| Standard-model MOQ | 50-100 units | Use a shared tooling plan across colours or silk prints to push the first order quantity down |
| Custom firmware / silk printing | 200-500 units | Firmware customisation is a one-off fee; negotiate amortising it across the first 3 orders |
| ODM new housing | 1,000-3,000 units | Write tooling cost (commonly RMB 15,000-60,000 for structural parts) into the contract as refundable against volume |
| Sampling | 3-7 days for stock models; 15-25 days for custom | Sample fee RMB 500-3,000, refundable against the bulk order |
| Payment | 30% deposit + 70% against B/L copy, or sight L/C | Hold 5-10% retention on the first order, paid after acceptance |
| Warranty | 12-24 months | Specify replacement vs repair, who pays freight, and the spare ratio (commonly 1-3%) |
The single most valuable thing to do at sampling: have the factory send the sample’s firmware version number, sensor marking photos and ONVIF conformance screenshots together, and bind them into the mass-production contract. A sample on a different version from mass production is the most common hidden downgrade in both e-commerce and project orders.
Five Common Pitfalls
- Sensor swap at the same spec: the quote says “4MP”, mass production uses a 1/3” sensor instead of 1/2.8” — invisible in daylight, blurry at night. Write sensor size and model into the contract.
- Borrowed certification: shipping on someone else’s FCC ID or CE report means the whole shipment is held if customs samples it. Require the FCC ID applicant to be your supplier.
- Understated PoE power: rated 802.3af, actually needs PoE+. Accept against peak draw with full IR plus PTZ movement.
- Firmware locked to one cloud: factory firmware bound to a vendor cloud loses AI and alarm features after a VMS change. Write the ONVIF Profile and open RTSP / ONVIF interfaces into the contract.
- Accessories excluded from the quote: waterproof connectors, brackets, screws and manuals added line by line later cost USD 1-3 per unit — USD 1,000-3,000 on 1,000 units. Confirm the packing list at quotation stage.
FAQ
Q1: What is the usual MOQ for a CCTV camera factory in China? Standard models run 50-100 units per model; custom firmware or silk printing runs 200-500 units; a full ODM with new housing runs 1,000-3,000 units. The real constraint is not assembly but housing tooling and SMT line changeover, so sharing one housing across colours is how you push the first order quantity down.
Q2: How do we judge whether a quotation for 1,000 units of a 4MP bullet is reasonable? First check it against the FOB anchor ranges to see if it is an outlier, then ask for an itemised quote: sensor model, SoC model, housing material, PoE class, whether accessories are included, and who holds the certification. At the same spec, a quote more than 30% below the lowest reasonable price almost always has something deleted.
Q3: What certification do we need to export to the US, and does NDAA apply to us? For commercial channels it is mainly FCC ID (Part 15C for radio models) plus RoHS; projects for government, schools, airports and utilities also need an NDAA compliance check. Check the final manufacturer including subsidiaries and associated brands against the prohibited list, not the private-label brand, because private label does not change manufacturer attribution.
Q4: How do we confirm a supplier is a real factory and not a trading company? Ask for time-stamped line video (SMT line, assembly line, burn-in room) plus 3 months of incoming material records, then open one unit and read the sensor and SoC markings. A trading company is not automatically unusable, but price structure, lead-time responsibility and inspection method all have to be negotiated on trading-company terms.
Q5: Can you do only a factory audit or inspection without handling the purchase? Yes. Inspection is RMB 700-2,000 per order depending on city and product complexity, with a report containing photos and measured data; a factory audit is RMB 1,500-3,500 per factory and covers the production line, incoming inspection and certification documents. For the full pre-shipment flow see surveillance camera QC and the pre-shipment inspection guide; sampling follows AQL general inspection level II.
