Photo verification outdoors, where unverified activations are most common and most expensive. Two PIR sensors, anti-masking, and a camera that photographs whatever triggered the alarm.
Built for the installer
Outdoor detection generates the most false activations on any system, and every one is potentially a call-out. Being able to look at the image and see a fox rather than a person ends the question immediately, without anyone driving to site.
The camera covers 105 degrees horizontally by 50 degrees vertically, shooting up to 640 x 352 with an IR backlight, and can deliver a series of up to five images. Photo delivery is about 9 seconds at 320 x 176 and up to 20 seconds at full resolution, so the resolution setting is a real trade-off against how fast the operator sees the frame.
Detection runs 10 to 49 feet across 90 degrees with LISA and SmartDetect filtering, rated -13F to 140F, with anti-masking reporting attempts to block the view.
Key features
- Photo verification outdoors, where unverified activations are most frequent and most expensive
- Anti-masking reports attempts to block the detector rather than failing silently
- LISA and SmartDetect filtering separates a person from foliage, rain and animals
- Series of up to 5 images rather than a single frame
- Rated -13F to 140F with temperature compensation across the range
- Pet immunity by height to 2.6 ft, weight not a factor
System requirements
Requires an Ajax hub that supports photo verification. Suitable for outdoor and indoor use. Photo delivery time depends on the resolution selected.
