For Haixi northern, high-altitude, large day-night temperature difference projects, choose the heated outdoor MW + dual PIR hybrid intrusion detector. Heating prevents frost/condensation on the housing, keeping MW and PIR windows clear, reducing winter false alarms.

Haixi outdoor solar PIR voice alert detectors require no mains power, no wiring. Integrated solar panel and battery design, stable endurance, suitable for off-grid or hard-to-wire outdoor scenarios: park perimeter, orchards, fish ponds, temporary construction sites, parking lots.

Haixi third-party testing: large projects (e.g., park perimeter) need third-party testing. ENIVE Tech cooperates with SGS, CTI, etc. Test items determined by user requirements and plan, cycle 5-10 days.

For Haixi projects, ENIVE Tech solar detectors use monocrystalline silicon panel + lithium iron phosphate battery combination with stable conversion efficiency. Standard configuration cloudy/rainy endurance 7-15 days; Haixi high-sunshine regions can exceed 30 days.

Haixi indoor project selection focus: ① Mounting (ceiling / wall); ② Coverage diameter (by room area); ③ Single-tech / dual-tech (by environment stability). ENIVE Tech recommends models and quantities based on Haixi indoor space.

Haixi outdoor detector common mounting methods: ① Wall mount (building side, 2.5-3.5m height); ② Pole mount (independent pole or fence pole); ③ Corner mount (building corner). Different mounting affects coverage and blind spots.

ENIVE Tech nationwide logistics direct to Haixi. Detectors are transported as ordinary cargo. Standard carton packaging, 1-20 units per standard carton, large batches use wooden frame or wooden box. Shaanxi ENIVE Tech Haixi Station focuses on Qinghai Haixi and surrounding markets, covering the following administrative districts/counties: Geermu City, Delingha City, Mangya City, Wulan County, Doulan County, Tianjun County, Dachaidanxingzhengweiyuanhui. users can pick up nearby.

Haixi custom detector stages: ① Requirement confirmation 1-2 days; ② Plan evaluation and scheduling 1-3 days; ③ Assembly 5-10 days; ④ Function and environment test 3-5 days; ⑤ Package and ship 1-2 days. ENIVE Tech dedicated follow-up.

Structurally, Haixi dual-tech detectors have built-in MW and PIR modules; single-tech has only PIR. The two look similar; dual-tech has better anti-interference. ENIVE Tech provides selection advice based on Haixi project false-alarm requirements.

For Haixi indoor projects, ENIVE Tech provides indoor ceiling-mounted PIR detectors and indoor ceiling-mounted dual-tech detectors. Single-tech PIR suits stable environments; dual-tech suits environments with small disturbances (fans, curtains). Haixi users select by scenario.

Haixi on-site guidance flow: ① User booking (3-7 days in advance); ② Technician visit (free within Shaanxi ENIVE Tech Haixi Station focuses on Qinghai Haixi and surrounding markets, covering the following administrative districts/counties: Geermu City, Delingha City, Mangya City, Wulan County, Doulan County, Tianjun County, Dachaidanxingzhengweiyuanhui., actual cost outside); ③ Site survey and layout (0.5-1 day); ④ Plan delivery (3 working days); ⑤ Installation and commissioning (by project scale).

Common Haixi selection pitfalls: ignoring heating needs (winter frost false alarms), ignoring small-animal resistance (high false alarm rate), ignoring mounting angle (detection blind spots). ENIVE Tech provides parameter advice and layout plan based on Haixi site conditions.

ENIVE Tech has a contact team in Haixi. Detector warranty usually 12-24 months, calculated from receipt. Within warranty, defects are replaced free; human or installation errors excluded. After warranty, paid service still provided.

From usage, Haixi outdoor detector false-alarm rate is greatly affected by mounting position. Avoid facing trees, AC outdoor units, vehicle lanes. ENIVE Tech provides layout advice and angle adjustment based on Haixi project site.
