Detailed Answer
Yes, unless you choose FHSS + independent pairing products. Fixed-frequency remotes on the same site inevitably interfere (same-frequency collision). The LIDEER LD series uses FHSS hopping + one-key pairing, so dozens of units on one site do not interfere; XINGJIA uses adaptive hopping. When selecting for multi-device factories, ask the supplier about 'units on the same site' as a key parameter.
| Fixed frequency | Inevitable interference |
| FHSS | Dozens on one site |
| Pairing | Independent per unit |
Note:If a workshop has more than 5 units, rule out fixed-frequency products outright.
