For Changde 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). Changde users select by scenario.

Large order payment: Changde users can settle by project stage. ENIVE Tech negotiates based on Changde user funding situation and contract rhythm.

From usage, Changde 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 Changde project site.

For Changde 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.

For Changde 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 Changde team provides layout advice.

Structurally, Changde 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 Changde project false-alarm requirements.

Changde 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.

Changde 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.
