3D Vision System	Elphel MNC393-XCAM	Reviewed competing products
Released	2018	2015-2018
Depth sensing technology		Active IR and projected pattern variations or SLAM variations
Depth range, m	10-5000	0.10-20
Depth accuracy	1% at 100m 5% at 500m 10% at 1000m 20% at 2000m	Some do not have information Passive systems (no IR), best: 1.5% at 10m 17.5% at 100m Active systems, best (ZiVID): 0.1mm @ 0.6m but the range is 0.6-1.1m HTC VIVE: 5% @ 2m (info by StereoLabs) ZED Mini by StereoLabs: 1% at 1m 9% at 10m
Depth Processing	Post-processing	Post-processing or real-time (mostly)
Number of image sensors	4 (square)	1-2
Stereo baseline, mm	250 (diagonal)	from single lens to 63-250
IR projectors	no	some have, some don't
Output interfaces	1 GigE USB2 eSATA (external storage) internal storage (m.2 SSD) Possible to precisely sync multiple systems	some have GigE most - USB3
Position and orientation	GPS Compatible with Analog Devices IMUs: up to 2460Hz	some have IMU (100-500Hz), but most don't
