Video passage monitoring
For sites where cameras can see clearly, Ark CV adapts to the equipment and footage already in place, then builds dependable passage outputs around the questions your team needs answered.

Fish monitoring built for the real world
See every passage.
Know what happened.
Fish don’t wait for clear water or convenient hours. Ark CV helps fisheries teams monitor passage around the clock—adapting to the cameras, sensors, and footage already available on site.

Monitoring solutions
Different sensors.
One source of truth.
Acoustic passage monitoring
When the water is too dark or turbid for a camera, acoustic imagery offers another way to observe passage. We start with your site, equipment, and footage to determine what a validated, reviewable solution can support.

Capture
We start with the cameras, sensors, and footage already available at your passageway.
→Find
We adapt the system to your site and bring likely passage events to the surface, so your team does not have to hunt through hours of footage.
→Review
A human-in-the-loop review process can be tailored to your team, your questions, and the level of review each decision requires.
→Decide
Use near-real-time outputs in the format you need—exported for analysis or built directly into your existing databases.
→Frequently asked questions
Start with the questions that matter at your site.
Do we need to replace our existing equipment?+
Usually, no. We begin with the cameras, acoustic systems, footage, and infrastructure already available, then assess what can be supported reliably at your site.
What outputs can Ark CV provide?+
Outputs are designed around the questions your team needs answered. Depending on the site and validation scope, that can include passage counts, direction, species, size, adipose-fin detection, injury monitoring, review clips, or reporting fields specific to your program.
What can acoustic imagery determine?+
That depends on the sensor, site conditions, species, and available training data. We begin with a feasibility assessment and define capabilities only after working with representative footage from your passageway.
What happens when conditions make analysis difficult?+
Ark CV flags cases where the system may be struggling and routes them through a configurable quality-assurance process. Those QA clips actively strengthen the training dataset so the system can handle similar conditions automatically in the future.
How does human review fit into the process?+
Human-in-the-loop review is adapted to the needs and risk profile of each site. Reviewers can focus on flagged cases and the events they choose without having to rewatch every hour of footage.
How quickly are results available?+
Reporting can be delivered in near real time. Results can be exported for analysis or built directly into a customer’s existing databases and reporting workflows.
How does Ark CV protect customer data?+
We treat site imagery and monitoring data as sensitive customer information and keep it secure throughout processing, review, and delivery. Specific data-handling requirements can be incorporated into each deployment.
How do we find out whether Ark CV will work at our site?+
Start by sharing representative footage, your existing equipment, and the monitoring questions you need answered. We’ll assess feasibility and outline a practical validation path.
WHY ARK CV
Built to go where the fish go.
Every passageway is different. Ark CV builds from the equipment you already have, adapts the analysis and human-review process to your needs, and validates the resulting system at your site. Our proven video work provides the foundation; acoustic imagery expands where that approach can go.
