Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
AI gun detection and automated emergency response for your existing security cameras
Turns passive surveillance cameras into proactive early-warning systems that recognize firearms and active-shooter threats in a fraction of a second.
Triggers coordinated actions the moment a threat is confirmed: locking doors, sounding alarms, pushing mobile alerts, engaging displays and notifying police.
Choose UL-certified professional monitoring or human-in-the-loop review within your own security operations center to confirm alerts before response.
Delivers detailed real-time alerts with time, location and imagery across mobile, desktop and on-premise displays, built on long-standing emergency notification expertise.
