Structurally, the Tongchuan heated detector has a built-in heating film and temperature switch; non-heated does not. Detection performance is similar; difference is in low-temperature adaptability. ENIVE Tech provides selection advice based on the Tongchuan project region.

Accessories-wise, Tongchuan outdoor detectors include brackets, waterproof connectors, heating power supply, etc. — ENIVE Tech provides as a set. Indoor ceiling detectors include ceiling brackets and installation manual. The Tongchuan team provides remote installation guidance.

For Tongchuan outdoor projects, focus on: ① Anti-interference (wind, small animals, light changes); ② Outdoor durability (IP rating, rain/dust proof); ③ Heating requirement (northern / high-altitude). ENIVE Tech provides selection list based on Tongchuan site.

Tongchuan existing customer payment: after 1 year cooperation with good credit, can adjust to more friendly payment rhythm. Need to provide business license, bank statements and other credit materials for cooperation evaluation.

For Tongchuan stable-environment indoor places (warehouses, server rooms), choose indoor PIR (single-tech) detectors — simple structure, good environmental adaptability. For complex environments or false-alarm-sensitive scenes, dual-tech is recommended. ENIVE Tech recommends based on the Tongchuan project.

Tongchuan receiving notes: ① Check outer packaging for damage; ② Verify quantity and list; ③ Check labels (item name, batch, production date); ④ Detectors are electronic products, avoid rain and violent collision. If problems, reject in writing within 24 hours and notify ENIVE Tech.

Tongchuan detector quality inspection flow: ① Incoming inspection (housing, modules, battery); ② Production process monitoring (welding, assembly, parameter adjustment); ③ Finished product inspection (detection distance, alarm output, heating function); ④ Environment test (high/low temperature, waterproof); ⑤ Visual inspection. ENIVE Tech ships with report.

Tongchuan solar detectors have built-in lithium battery. Under normal sunlight, continuously works 15-30 days (depending on trigger frequency). Continuous rainy weather may shorten endurance. Plan redundancy based on Tongchuan project region climate.

Tongchuan standard model detectors are stocked 5-10 days; custom models 15-25 days (by complexity). Expedited orders can be prioritized. ENIVE Tech nationwide logistics direct to Tongchuan, 3-7 days delivery.

Tongchuan sample and small-batch order handling: ENIVE Tech supports sample supply (1-2 units), using standard models, facilitating Tongchuan project early verification. After sample acceptance, bulk orders proceed per project flow; samples can be incorporated into the bulk contract.

Tongchuan outdoor detector scenarios: ① Park perimeter (wall / fence); ② Villa courtyard; ③ Parking lot; ④ Temporary construction site; ⑤ Orchard / forest farm; ⑥ Aquaculture farm.
