Sentry Time and Attendance
Time and attendance system for security companies
Guards clock in on a handset at the post, by face, NFC card or barcode, against the site’s geofence. Rosters, breaks and leave sit in the same system, and approved hours become pay and an invoice without re-keying.
Book a DemoTL;DR — Quick Summary
Sentry is a time and attendance system built for South African security companies. Guards clock in on a shared Android handset at the post, the clock-in is checked against the site's boundary and the roster, and the hours flow through to timesheets, pay and client invoices.
- What is a time and attendance system?
- Software that records when each employee starts and ends work, checks it against their roster, and turns the hours into timesheets for payroll. For a security company it also has to prove the guard was at the right site.
- How do guards clock in with Sentry?
- On the Sentry handset at the post. The app finds the site in about three seconds, then the guard proves who they are by face, NFC card, ID card barcode or a barcode made from their employee number.
- How does it stop buddy clocking?
- Identity and location are checked separately. Face recognition proves who is clocking in, and the geofence or an NFC tag at the post proves the handset is on site.
- Does it work without signal?
- Yes. A clock-in made offline is saved on the handset and sent when signal returns, with the time it actually happened. A guard who clocks in at 03:10 and syncs at 06:00 is recorded at 03:10.
- Can we keep our EasyRoster or Matrix rosters?
- Yes. Sentry imports rosters from EasyRoster and Matrix, including grades and the day, night, off and leave codes, and shows you the result before anything is saved.
- Does Sentry track guards through the shift?
- No. It records the position when a guard clocks in or out and when they record something. The timesheet map shows those points only.
What the time and attendance system covers
From the guard clocking in at the gate to the invoice your client receives at month end.
Clocking In at the Post
Proving who the guard is and that they are at the site, on a handset that stays there.
Sentry Guard App for Android
A native Android app on a shared handset at the post, deployed and updated across the fleet through mobile device management. Clock-ins and breaks are saved on the handset when there is no signal and sent when it returns.
Clock-In and Clock-Out
Guards prove who they are by face, NFC card, ID card barcode or a barcode made from their employee number. Late arrivals are flagged against the grace period, and a forgotten clock-out does not leave a shift open for ever.
Geofencing
Each site has a circular or polygon boundary. A clock-in outside it is refused, and the guard sees the nearest site, the distance, the boundary and how accurate the position is, rather than a bare error.
Face Recognition
A guard is enrolled on the handset in a few minutes and then clocks in by looking at the camera. If the face is not recognised, the guard switches to another method and the shift still starts.
NFC Tags at the Post
Where GPS cannot be trusted, such as basements and large buildings, an NFC tag fitted at the post proves the guard is there by touch.
Rosters and Shifts
Getting the right guard to the right site, including the roster you already keep elsewhere.
Rosters and Shift Patterns
Shift pattern templates, calendar views and automatic guard allocation, with rosters sent to guards by email and WhatsApp. A guard cannot clock in for a shift they are not rostered on.
Roster Import from EasyRoster & Matrix
Import rosters you already keep in EasyRoster or Matrix instead of re-keying them. Sentry reads guard name, grade and the day, night, off and leave codes per site, and shows you the parsed roster before anything is written.
Standby Rosters
Keep a pool of guards on standby and allocate one to a site the moment a shift goes unfilled. Day and night standby carry their own start and end times, and a guard returns to the pool when the cover ends.
Shift Handovers
The outgoing guard logs the handover with photographs, and it attaches to the site’s record so the incoming shift and the control room read the same account.
Breaks, Leave and Cover
What happens between clock-in and clock-out, and who is covering when someone is away.
Breaks
Guards see only the breaks their site allows and have not taken yet. The due-back time comes from the system rather than the handset’s clock, and a late return is recorded with how late it was.
Leave Management
Eight leave types including annual, sick, maternity, paternity and study leave. Balances with carry-over, an approval workflow, and balance reports emailed on a schedule.
Live Site Cover
See who is on site now across every site, day and night shift. Understaffing shows up as soon as a shift starts without a clock-in, alongside overtime alerts.
Timesheets, Pay and Invoices
Turning approved hours into pay and an invoice without a separate spreadsheet.
Timesheet Map View
A map of where each guard was when they clocked in and out, drawn against the site boundary. Sentry does not track guards through the shift, so the map shows those two points and nothing in between.
Pay Rates
Hold a pay rate against each guard so timesheet hours turn into cost without a separate spreadsheet.
Invoicing & Statements
Invoices generated from approved timesheets, with line items, VAT, your own templates, payment tracking and consolidated statements for clients with several sites.
Attendance Reports
An attendance register per site with each guard’s clock-in and clock-out times, hours worked, pay and the position recorded at clock-in. Employee hours breakdowns and timesheet exports can be emailed on a schedule.
Client Portal
A PIN-protected page per client showing attendance rates and geofence compliance for their sites, so the client can check cover without phoning you.
The rest of Sentry
Time and attendance is one part of Sentry. Each of these has its own page.
