Moreover, proximity to ports such as Shekou and Xiamen reduces shipping lead times and logistics costs—critical factors for global distribution.

Key Criteria for Choosing the Right Intercom System Supplier

Selecting a manufacturer isn't just about price or volume—it's about aligning with a partner who can support your brand’s reputation, product roadmap, and customer satisfaction goals. Consider the following criteria when evaluating potential suppliers:

1. Technical Expertise and Product Innovation

Top-tier suppliers invest heavily in research and development. Look for companies with in-house engineering teams capable of designing both hardware and software components.
