For Xi'an 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.

Xi'an 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.

Structurally, Xi'an 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 Xi'an project false-alarm requirements.

For Xi'an 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; Xi'an high-sunshine regions can exceed 30 days.

Xi'an 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 Xi'an indoor space.

From usage, Xi'an 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 Xi'an project site.

For Xi'an park perimeter projects, ENIVE Tech recommends detection distance based on perimeter length and pole spacing. Generally: 3-5m pole spacing choose 8m; 5-8m choose 12m; 8-12m choose 15m. The Xi'an team provides layout advice.

Xi'an 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.
