Is it possible to export the detection? For example over serial or ethernet to give an object, its size and position within the detection area? It is possible to raise the detection "floor" or is there some intelligence built-in to account for very gradual changes? Thinking if the approach was a green driveway with grass growing between mowing, or with snow build-up. Do these interfere with each other if the fields are too close?
Tim, these are all good questions. As of right now, there is no way to program it with an ethernet connection, but there is a bluetooth app you can download on your cell phone to program these dimensions in. In order to raise the "floor", you will adjust a setting called "Uncovered Zone". This lifts the field x amount of inches off of any surface or floor. The sensors should not interfere with each other, but one Widescan is typically enough to cover one side of a door. The dimensions are the mounting height multiplied by 1.2. So for example, at 10ft high you would get a 12x12ft field Hopefully this helps
@@JacobDiBattistaBEA Thanks for the speedy reply. I'm not just asking about programming, but also telemetry of current detections in use (i.e. what the sensor currently sees) - essentially I'm poking and proding if this product is potentially suitable for a cost reduction for example a SICK 3D lidar. Feels like it's close, but has some weaknesses in very specific cases this sensor may not be intended for. All the setup and installation videos seem to contrust rectangular detection zones - what if two of these were installed back to back on a post, with the alarm zone in a circle around said post? Perhaps rather than just presence and safety zones I'd want to know in which of 5 movements that detected object was moving: Towards, Away, Across Left, Across Right, Stopped. I'm bringing this up due to the other videos about use in security for things like museums. In a case where one was intending to protect another device like a camera with a lower cost device of a different technology, we'd want to be able to deal with variable environmental issues. When we think about security, we don't think what the most upright citizen is going to do - we think lowest point, crackhead thinking, then add bad intentions to it, and for even higher threats: patience. A regular person might have an issue rolling in mud or snow to avoid a sensor, a crackhead not so much - and a patient person who is aware of temporal noise reduction in a sensor might know to make very slow and small changes (think sniper school, multiple hour-long crawls). If the uncovered zone is more than the flat height of a person laying on the ground or barbed-wire/belly crawl it will not detect a person below it. I'm guessing that the Uncovered Zone is also planar (based on a single height mentioned, and other videos discussing issues with planarity errors). What you might consider for robustness, is the ability to scan a surface with is not a perfect plane (wheel ruts, ditches, etc.) and then add a zone which follows the contour of that detected surface for which slow changes are allowed over time (think hours). Beyond that, you could probably do with more facets on the rotating mirror - at a height of 18-20 feet, 7 beam sweeps would create an approximate gap of 3 feet between scan planes. This may not be big enough for a person to hide in parallel to the scan plane, but it would deprive the sensor of context providing resultion of a detected object. A rough estimate is that a person occupies about 2-1/4 cubic feet of volume (roughly 65000 cubic centimeters) - I'd want to be able to resolve down to 1/10th that volume within the detection envelope, so that a threshold for detection could be derrived against the uniform-time-varried ground surface (which would allow one to account for snow shadows due to building eves). So in telemetry, I'd want to see "Object(n), direction(maybee speed ft/s), volume, zone". Might be a bit much to ask of a low cost sensor. Bluetooth and IR remotes brings up another question - do you lock out both with a cover installation, and provide a tamper detection switch on the cover? In security-centric applications configuration changes (and attempts) need to trigger a tamper alarm.
