For Zhangjiajie 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 Zhangjiajie team provides a selection list per site.

Structurally, the Zhangjiajie 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 Zhangjiajie project region.

Zhangjiajie solar detector selection considerations: ① Average daily sunshine (affects charging efficiency); ② Load power (voice / alarm output); ③ Mounting position (no shading, sufficient sunlight). ENIVE Tech provides selection and installation advice based on Zhangjiajie project site.

Zhangjiajie 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.

For Zhangjiajie 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 Zhangjiajie team provides anti-interference advice on site.

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

ENIVE Tech provides remote or on-site technical guidance for Zhangjiajie park perimeter, indoor ceiling, outdoor solar projects. Complex projects can book on-site guidance, on-site service within Shaanxi ENIVE Tech Zhangjiajie Station focuses on Hunan Zhangjiajie and surrounding markets, covering the following administrative districts/counties: Yongding District, Wulingyuan District, Cili County, Sangzhi County..

For Zhangjiajie 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 Zhangjiajie project.

Zhangjiajie 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.

Zhangjiajie 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.

Zhangjiajie outdoor detectors common detection distance is 8m / 12m / 15m three grades; some large-range projects can be customized to 25m. MW + dual PIR hybrid detection angle is about 90°-110°; coverage relates to mounting height.

Zhangjiajie 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.
