Bosch Visual Gun Detection Tested
Bosch is well known for its video analytics generally (see IPVM's 2024 video analytic rankings), and now it has released visual gun detection perform but how well does that work?
Based on IPVM's months of testing Bosch's visual gun detection system, we detail:
- How did Bosch perform in detecting firearms on the scene?
- How was Bosch's performance with false alerts on innocuous objects?
- What is the alert latency of the visual gun detection solutions?
- How did Bosch perform in low light (~50 lux)?
- What does Bosch's setup entail?
- What is Bosch's approach to visual gun detection?
Bosch is the second in a series of visual firearm detection tests. For IPVM's first test, see Scylla Gun Detection System Tested. Along with the other manufacturers tested, we also examine various manufacturers' live demos and claims for baseline comparisons.
