Snowline Joint Unified introduces AI-enabled camera system with firearm detection, license-plate reading and vape sensors

Snowline Joint Unified officials gave the school board and the public a live demonstration of a new AI-enabled campus surveillance system that adds firearm-detection alerts, license-plate recognition and environmental "vape" sensors while nearly doubling the district's camera fleet.

The presentation, delivered by Chief Todd Espindola, Director Rick Hernandez and staff, outlined what they described as a staged roll-out of roughly 600 IP cameras districtwide and new analytic features intended to speed investigations and give school leaders and police earlier notice of threats.

Board members were shown how the system can search footage using natural-language queries, follow a vehicle or a person across cameras, and send automated alerts when a firearm or a flagged license plate appears. Hernandez demonstrated an interface that searches by clothing or object ("person with Dodgers hat") and an automated "journey" function that stitches clips from multiple cameras into chronological video.

School and police officials stressed several operational limits and safeguards. Espindola said the district stores footage on local servers with 180 days of retention and more than a petabyte of local storage; a cloud interconnect exists only to support the access layer and certain analytics. District staff said any video transmitted to cloud services is deleted after processing and that firearm-detection analytics require a higher-accuracy provider.

Officials also described access controls and governance. Espindola said requests for camera access are routed to him and to Bob Chacon, with the director and a maintenance representative involved; principals submit lists of employees who should get access. The system supports three access levels: full (live view, rewind, download), rewind-only (no download), and live-only.

Privacy questions came up from the board and public. Hernandez and Espindola said there are no cameras placed where people have a reasonable expectation of privacy. Vape sensors are environmental sensors placed inside restrooms at the secondary level, they said; the sensors trigger a short clip (about 30 seconds before and after the event) linked into the camera system, but they emphasized the sensors are not cameras. Espindola said the district will not install hidden cameras and that most cameras are visible and in publicly open campus locations.

Technical and deployment details given during the presentation included: the district previously had roughly 300 cameras and has installed about 362 so far, with a target near 600; many new units include license-plate readers and higher-resolution optics (minimum 5 megapixel, some 4K units for long-throw coverage); infrared capability for low-light operation; and an expected field life of the cameras of roughly 10–15 years. Staff said they expect to complete the majority of installations within about a month, with some sites requiring trenching, poles or other work that could push completion a month or more beyond that date.

Espindola also described how staff use footage for daily monitoring, incident verification, identification of subjects and building timelines for investigations and after-action reviews. He reported the old camera system sometimes showed incorrect timestamps; the new system, he said, resolves that problem and reduces the need to annotate reports.

On retention and analytics, Hernandez said the district will keep 180 days of footage locally. He described the system as a local deployment running a local large language model for search; only a narrow set of analytic results (e.g., some firearm and slip-and-fall detections) use an external cloud component and those uploads are deleted after processing, he said. He also said facial recognition and person-of-interest alerts are available and can be configured so a photo or a license plate triggers a push/text alert to staff phones.

Several board members asked about dark‑light performance, redeployment of cameras as needs change, and whether existing conduit, junction boxes and Ethernet runs will allow camera moves. Hernandez said the cameras are commodity IP models, powered over Ethernet, easy to remount as cable runs allow. Espindola said principals such as Debbie Barber already have begun identifying employees who should get access; a handful of people will receive the highest access level.

Direct board action on the system was not requested; the presentation was informational. Staff described ongoing steps: completing deployment, finalizing access lists, documenting retention and governance policies, and returning with operational procedures if the board wants formal policy language. Espindola and Hernandez invited questions and said they would be available to meet with principals and community members about placement, access and safeguards.

Why it matters: district officials said the new capabilities can speed investigations, allow timelier responses to threats and reduce uncertainty for police and administrators. Community members and board members asked for written policies clarifying who can access, how long footage is stored, and how the district will ensure cameras are not placed in locations that reasonably expect privacy.

What’s next: staff said they will continue the staged installation and finalize access requests; administrators also said they would provide more written documentation about retention, access levels and the limited cloud use for analytics.
