Choosing the right IP video intercom supplier is one of the most important decisions a distributor can make. The quality of your supplier directly impacts your product reliability, your margins, and your reputation. But with thousands of manufacturers and trading companies claiming to be “the best,” how do you separate the genuine from the pretenders? This guide gives you 10 essential questions to ask before you place an order—so you can source with confidence.

The global video intercom market is booming. Valued at USD 28.4 billion in 2025, it is projected to reach USD 125.7 billion by 2035, growing at a compound annual growth rate of 16.6%. The shift from analog to IP-based systems is accelerating, driven by demand for remote access, cloud management, and smart building integration.

For distributors, this growth represents a massive opportunity. But it also means more suppliers are entering the market—some with excellent products and processes, others with little more than a website and a promise. Asking the right questions is the best way to protect your business.

Here are 10 questions every distributor should ask before buying IP video intercoms from a supplier.

---

1. Are You a Manufacturer or a Trading Company?

This is the most fundamental question. Many suppliers claim to be factories, but in reality, they are trading companies, agents, or resellers. Working with a trading company adds cost, reduces transparency, and often limits customization.

Why it matters: A true manufacturer controls production, quality, and lead times. A trading company controls none of these—they are at the mercy of their supplier.

What to look for:

• A physical factory address and a willingness to host visits (in person or virtual).
• Evidence of production equipment: SMT lines, injection molding, aging rooms, test labs.
• In-house R&D team for hardware, software, and firmware.
• Certifications in the factory’s own name, not a third party’s.

Red flags: Vague answers about production, refusal to show the factory, certificates that don’t match the company name.

Why FARHD: FARHD is a source factory founded in 1998, with our own production lines, aging test lab, and R&D team in Shenzhen, China. We welcome factory visits and virtual tours.

2. What Certifications Do Your Products Hold?

Certifications are not just marketing badges. They prove that a product has been tested and meets international standards for safety, electromagnetic compatibility, and environmental responsibility.

Why it matters: Without the right certifications, your products may be rejected at customs, banned from sale, or fail in the field.

Essential certifications for IP video intercoms:

Certification	Region	What It Covers
CE	European Union	Safety, EMC, radio equipment (for wireless)
FCC	United States	Radio frequency compliance
RoHS	EU / Global	Restriction of hazardous substances
IP65 / IP66	Global	Dust and water resistance for outdoor stations
EMC	Global	Electromagnetic compatibility
ISO 9001	Global	Quality management system

What to look for: Certificate numbers, issuing laboratories, and model-specific documentation.

Red flags: Generic certificates, certificates in another company’s name, refusal to provide documentation.

Why FARHD: All FARHD products carry CE, FCC, RoHS, IP65, and EMC certifications. Documentation is available upon request.

3. What Is Your Quality Control Process?

Quality is not something you can inspect into a product at the last minute. It must be built into the process. A supplier without a rigorous QC system is a supplier you cannot trust.

Why it matters: Poor quality leads to warranty claims, service calls, and damaged reputation—all of which cost you money and time.

Key QC checkpoints to ask about:

• Incoming material inspection – Are components tested before production?
• In-process inspection – Are units checked at multiple stages?
• Functional testing – Is every unit powered on and tested for display, touch, camera, audio, calling, and unlocking?
• Aging test – Do units run continuously for 12+ hours under elevated temperature and humidity?
• Waterproof testing – Is IP65 rating verified on every outdoor station?
• Temperature cycling – Are products tested from -40°C to +70°C (or -20°C to +70°C for battery models)?
• Salt spray testing – For coastal environments, is corrosion resistance verified?

What to look for: A documented QC process, test reports, and a willingness to share details.

Red flags: Vague answers, no testing equipment, “we test every batch” without specifics.

Why FARHD: Every FARHD unit undergoes functional testing, 12+ hour aging, waterproof testing, and temperature cycling. We have high-low temperature chambers, salt spray test machines, and aging test devices in-house.

4. Can You Provide Samples for Testing?

Never commit to a large order without testing a sample first. A sample allows you to evaluate build quality, performance, and compatibility with your market requirements.

Why it matters: A product that looks good on a spec sheet may disappoint in real-world use. Testing a sample protects you from costly mistakes.

What to look for:

• Willingness to provide samples at a reasonable cost (or free for qualified buyers).
• Sample lead time and shipping options.
• Support for testing: technical documentation, app setup, and troubleshooting.

Red flags: Refusal to provide samples, excessively high sample costs, long sample lead times.

Why FARHD: We offer samples for testing and provide full technical support. We are confident that once you test a FARHD product, you will understand the quality difference.

5. What Is Your OEM/ODM Capability?

If you want to build your own brand, you need a supplier with strong OEM/ODM capabilities. Not every manufacturer can customize hardware, software, and packaging to your requirements.

Why it matters: Customization differentiates your brand, improves margins, and builds customer loyalty.

What to ask about:

• Custom logo on device, boot screen, packaging.
• Multi-language UI (Hebrew, Arabic, French, Spanish, Russian, etc.).
• Hardware customization: housing color, material, button layout, screen size, camera module.
• Software customization: UI design, feature toggles, API integration.
• Packaging customization: retail-ready boxes, user manuals.
• SKD solutions for local assembly.

What to look for: In-house engineering team, experience with OEM/ODM projects, flexible MOQ.

Red flags: “We only do standard products,” inability to customize software, high MOQ for customization.

Why FARHD: FARHD offers comprehensive OEM/ODM services with no MOQ for trial orders. We support custom logo, multi-language UI, hardware modifications, and SKD solutions.

6. What Is Your Production Capacity and Lead Time?

You need a supplier who can scale with your business. If they cannot handle your order volume or deliver on time, your business suffers.

Why it matters: Late deliveries mean lost sales, unhappy customers, and damaged relationships.

What to ask:

• Monthly production capacity.
• Standard lead time for standard products and custom orders.
• Ability to handle large orders (e.g., 10,000 units).
• Flexibility for urgent orders.

What to look for: A factory with multiple production lines, a stable workforce, and a proven track record.

Red flags: Vague answers about capacity, inability to provide lead time guarantees, history of late deliveries.

Why FARHD: Our factory in Shenzhen operates with advanced SMT lines, assembly lines, and a dedicated workforce. We have completed over 10,000 large-scale projects and can handle orders of any size.

---

7. What Is Your Warranty and After-Sales Support?

Even the best products can have issues. What matters is how the supplier handles them.

Why it matters: A supplier who disappears after the sale leaves you to deal with problems alone.

What to ask:

• Warranty period (minimum 1 year is standard).
• Process for handling defective units (replacement, repair, credit).
• Technical support: documentation, remote assistance, training.
• Spare parts availability.

What to look for: A clear warranty policy, responsive support team, and a commitment to long-term partnership.

Red flags: No warranty, slow support responses, refusal to provide technical documentation.

Why FARHD: We offer a 1-year factory warranty, technical documentation, remote assistance, and spare parts availability. Our support team is ready to help.

---

8. Do You Have Experience with Projects in My Region?

Different regions have different requirements: climate, regulations, voltage, language, and user expectations. A supplier with experience in your region is better equipped to meet your needs.

Why it matters: A product designed for one market may not perform well in another. For example, a video intercom that works in mild European weather may fail in the extreme heat of the Middle East.

What to ask:

• Experience with projects in your country or region.
• References or case studies from similar projects.
• Adaptations for local climate (e.g., wide-temperature operation).
• Compliance with local regulations.

What to look for: A supplier who understands your market and can provide relevant references.

Red flags: No experience in your region, inability to provide references.

Why FARHD: FARHD products are trusted in over 90 countries, including Russia, Northern Europe, the Middle East, Canada, and Southeast Asia. Our wide-temperature designs are built for harsh climates.

---

9. What Are Your Payment Terms and Shipping Options?

Clear payment and shipping terms are essential for a smooth transaction. Ambiguity here can lead to disputes and delays.

Why it matters: You need to know exactly what you are paying for, when, and how the goods will reach you.

What to ask:

• Payment terms: T/T, L/C, PayPal, etc.
• Deposit percentage and balance payment timing.
• Shipping options: EXW, FOB, CIF, DDP.
• Shipping partners and estimated transit times.
• Packaging for export (palletized, shrink-wrapped, etc.).

What to look for: Transparent terms, flexibility, and a logistics team that can handle international shipping.

Red flags: Requests for full payment upfront, unclear shipping costs, no experience with export documentation.

Why FARHD: We offer flexible payment terms, competitive shipping rates, and full export documentation support. We ship worldwide with trusted logistics partners.

---

10. Can You Provide References or Case Studies?

The best way to evaluate a supplier is to talk to their existing customers. References give you insight into real-world performance, support quality, and reliability.

Why it matters: A supplier with satisfied customers is a supplier you can trust.

What to ask:

• Contact information for 2-3 references in similar markets.
• Case studies of large or complex projects.
• Customer testimonials or reviews.

What to look for: Willingness to share references, positive feedback, long-term customer relationships.

Red flags: Refusal to provide references, vague case studies, negative online reviews.

Why FARHD: We have a long list of satisfied partners worldwide and are happy to share references upon request. Our track record speaks for itself.

---

Bonus Question: Can I Visit Your Factory?

If you are placing a large order, a factory visit is invaluable. It allows you to verify production capabilities, meet the team, and see quality processes firsthand. If a visit is not possible, ask for a live video tour.

What to look for: A genuine factory with organized production lines, testing equipment, and a professional team.

Red flags: Refusal to allow a visit, excuses about “security” or “busy schedule.”

Why FARHD: We welcome factory visits and virtual tours. Come see how your products are made.
