Structurally, the Weihai 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 Weihai project region.

Weihai 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.

Accessories-wise, Weihai 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 Weihai team provides remote installation guidance.

For Weihai outdoor projects, ENIVE Tech outdoor detectors include heated and non-heated versions. Northern / high-altitude projects should choose heated; southern / low-altitude can use standard. Detection distance 8-15m. The Weihai team provides a selection list per site.

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

For Weihai outdoor projects, ENIVE Tech outdoor detectors use Digital Signal Processing (DSP), identifying the difference between small animals (<25kg) and people, with low false-alarm rate. The Weihai team provides anti-interference advice on site.

For Weihai 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 Weihai site.

Weihai 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.

Weihai 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 Weihai, 3-7 days delivery.

Weihai 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.

Weihai 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 Weihai project region climate.

Weihai 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.
