What's the difference between the 3.5 mm and 7 mm lens?
The 3.5 mm gives a wide 48° thermal view for covering open areas at shorter range. The 7 mm narrows to 24° for long-range detection down perimeters and approaches — vehicle detection reaches roughly 894 m. Both share the same 256 × 192 thermal core and 4MP colour camera.
Can it really see in complete darkness?
Yes. Thermal imaging detects heat, not reflected light, so it works in 0-lux darkness with no IR illuminator — and continues to see through glare, shadow, smoke, dust and light fog where standard cameras struggle.
How accurate is the temperature measurement?
It measures −20 °C to 150 °C with ±2 % accuracy and lets you set point, line and area rules with threshold, difference and rate-of-rise alarms — ideal for early fire warning and monitoring electrical panels or machinery.
Does it reduce false alarms?
Yes. Deep-learning VCA classifies detected objects as human or vehicle and ignores animals, foliage and weather, so intrusion, line-crossing and loitering alerts stay meaningful.
How is it powered and what recorder do I need?
Power it over a single PoE (802.3af) cable, or via 12 VDC / 24 VAC. It streams H.265 with ONVIF Profile S/G/T, so it works with VIVOTEK NVRs and most ONVIF-compatible recorders and VMS platforms.
Is it suitable for outdoor Australian sites?
Absolutely. The IP66 die-cast housing is rated −40 °C to +60 °C, backed by a 5-year manufacturer warranty and local Australian support and stock.
