The real cost
Weak Proof Costs Real Contracts.
Most security teams lose client trust not because the patrol didn't happen, but because they can't prove it clearly, professionally, and fast enough.
“Did the guard actually show up?”
Clients question whether patrols happened. Without verifiable proof, their doubt is reasonable.
Paper logs look weak
Handwritten notes and spreadsheet summaries undermine the professionalism of the service you deliver.
Supervisors can’t defend the work
When a client pushes back, your team has no structured evidence to show the patrol was completed properly.
Weak reporting puts revenue at risk
Disputed shifts lead to refunded invoices. Poor documentation turns routine contracts into lost accounts.
The deliverable
Reports That Defend the Work.
Every shift produces documentation your team can stand behind and your clients can review.

The process
Patrol In. Proof Out.
A clear chain from field activity to verified documentation.
Patrol Begins
The guard starts their shift, checks in at the assigned site, and begins the patrol route. Location is verified at start.
Activity Gets Verified
Timed patrols, QR/NFC checkpoint scans, and GPS check-ins build a verification trail throughout the shift.
Evidence Gets Attached
Photos, incident notes, and observations are logged in context. Each entry carries a timestamp and location.
Reports Are Generated
Officer and site reports are generated with verification scores, evidence summaries, and structured documentation.
Core capabilities
Built Around Real Patrol Verification.
Location Verification
GPS-backed presence confirmation
Guards check in with GPS-verified location signals throughout their shift. Each check-in is timestamped and measured against the assigned site boundaries.

Questions Before You Start?
No. Sentinel Hound is a patrol verification and reporting platform. It confirms that guards were on-site at the right times by collecting GPS check-ins, checkpoint scans, and timed patrol data. It is not a live monitoring or real-time tracking tool.
Verification is built from multiple signals: GPS location check-ins, QR/NFC checkpoint scans, timed patrol compliance, and attached evidence like photos and incident notes. These signals are combined into a verification score that explains how well a shift was covered.
Two primary report types: Officer Verification Reports (per-guard, per-shift documentation with scores, checkpoints, incidents, and summaries) and Site Summary Reports (aggregated site-level overview with coverage trends and compliance data). Both are structured for client review.
Simple: $49/month base plus $2 per active guard per month. All features are included. No per-feature tiers. The 7-day trial includes up to 5 guards at no cost.
Yes. You can manage multiple sites under one account. Each site has its own checkpoints, patrol routes, and reporting. Site reports aggregate data per location for easy client-facing documentation.
