Detailed Answer
Import substitution: same-level functionality at 1/5~1/10 the price. Logic: core components (RF chips/relays) sourced globally, R&D + manufacturing localized to cut costs, features benchmarked against imports. Risk control: trial before use, case endorsement, after-sales guarantee. Domestic import substitution is the current mainstream trend in industrial procurement.
| Cost cut | Local manufacturing |
| Benchmark | Same-level features |
| Verification | Trial before replace |
Note:Do thorough verification before substituting to reduce risk.
