AI Mobile Phone Detection System for Global Workplaces

An AI mobile phone detection system uses computer vision to recognise when a person is holding, viewing, or talking on a mobile phone within a monitored no-phone zone, through your existing CCTV cameras, and alerts a supervisor in real time with a timestamped snapshot and clip. It detects the visual act of phone use — not what is on the screen, and not a radio signal. Workplaces use it to enforce a no-phone policy for safety, quality, and productivity, transparently and per zone.

Your existing IP cameras stream to the AI over standard ONVIF and RTSP protocols. A deep-learning model recognises the visual signature of phone use in the zones you define — phone-in-hand, phone-at-ear, phone-viewing — and validates each detection across multiple consecutive frames to reduce false alarms. When a detection is confirmed, an alert fires with a snapshot, camera ID, zone, and timestamp, and the clip is saved for supervisor review. No phone-detecting hardware is added — the intelligence sits in the software layer running on the cameras you already have.

This is the honest crux of any visual AI system: in a poor frame, a wallet, radio, TV remote, or handheld tool can resemble a phone. Tentovision reduces false positives by validating across multiple frames and improves further with good camera placement, resolution, and lighting. After per-site calibration, accuracy is commonly cited above 95 percent — this figure is illustrative and must be verified for your specific environment. Because every alert carries the clip and snapshot, a human supervisor confirms every detection before any action, so a false alarm is caught by the review layer, not acted on.

Monitoring your own workplace for policy compliance is generally permissible when it is for a legitimate purpose, when employees are given prior notice via a clear phone-use policy, and when data is handled in line with the applicable data-protection regime — the DPDP Act 2023 in India, the EU General Data Protection Regulation in Europe, and equivalent employment-law regimes in the US and other jurisdictions. This is very different from signal jamming, which is illegal for private use under India's telecom law (the Indian Telegraph Act and related rules) and is regulated or restricted in most other jurisdictions. Transparency is the key: staff must know the policy, know that designated zones are monitored, and the data must be used only for the stated purpose. This is not legal advice — customers should confirm their specific setup with their own legal and HR teams.

Yes. Tentovision is vendor-agnostic and connects to any IP or CCTV camera you already own over ONVIF and RTSP — Hikvision, Dahua, CP Plus, Uniview, Sparsh CCTV, HiFocus, Axis, Vivotek, Bosch, Pelco, Honeywell, Tiandy and 200+ other brands (brand count subject to ongoing validation). Detection quality depends on the camera's angle, resolution, and lighting over the specific zone you want covered, which is confirmed at the site-assessment stage. Most estates start with their highest-risk zones — production floor, assembly line, clean room — and expand from there.

Accuracy depends on camera placement, camera resolution, zone lighting, and per-site calibration. After calibration, accuracy is commonly cited above 95 percent — this figure is illustrative and requires per-environment verification. No visual AI system is perfect. Tentovision validates every detection across multiple consecutive frames to cut false alarms, and treats every alert as a flag for human confirmation rather than automatic proof. That human-review step is what keeps the system fair and practical on a real work floor and protects honest workers from being wrongly accused.

Yes. You define phone-free zones such as production floor, assembly line, clean room, or hazardous chemical zone; and phone-allowed zones such as the canteen, break room, or lobby where nothing is flagged. Rules can also be time-based — phones restricted during shift hours and allowed on breaks. The same camera system applies the policy you set, consistently and uniformly per zone, so the same phone-in-hand pose is flagged on the line but ignored in the break room.

Within seconds of a confirmed detection, the supervisor receives an alert via SMS, WhatsApp, email, or a dashboard popup — including a snapshot of the incident, the camera ID, the zone name, and the exact timestamp. Alert recipients are configurable per zone, so a chemical-zone alert can route to safety and a QC-station alert can route to the quality lead. Repeated violations can escalate to HR or plant management under rules you set. The design intent is action in the moment, not a report at the end of the shift.

An RF phone detector senses a phone's radio signal — it can tell you a phone is present and transmitting somewhere nearby, but not who is using it, in which specific location, or whether the phone is just in a pocket. It is also blind to phones that are switched off or in airplane mode. AI camera detection sees the phone in hand and detects the act of usage, tied to a zone and a timestamp, with video evidence, on your existing cameras. RF is the right tool for contraband screening at prison entrances, exam halls, and secure facilities; AI camera detection is the right tool for enforcing a workplace policy where the goal is to catch use with evidence. Phone jammers are a separate category entirely — they block signals, they are illegal for private use in India and restricted in most jurisdictions, and they interfere with legitimate communications; Tentovision does not jam, intercept, or block anything.

Yes. Tentovision is a modular AI video analytics platform — multiple analytics modules run on the same camera feeds simultaneously. You can add PPE detection, fire and smoke detection, intrusion detection, and other safety analytics on the same infrastructure through the same platform. This is usually far more cost-effective than deploying separate systems because it reuses the cameras and network connections you already have. Camera health monitoring is included on the platform, not sold as a separate paid add-on. You choose which modules run in which zones.
