Police Evidence, Armory & Equipment Tracking with RFID
Every firearm, every piece of evidence and every officer, tracked from the door to the shelf. RFID readers at each doorway log who walked out with what, and when — a timestamped chain of custody for every evidence bag, written for you.
Part of Senitron’s RFID asset tracking software.
How Police Departments Use Senitron RFID
Evidence you can defend
A timestamped chain of custody for every bag in the evidence locker: booked, submitted to intake, logged into the locker, out to the crime lab or court, and back.
Armory and duty gear
Duty pistols, patrol rifles, Tasers, body cameras and radios are tied to the officer who carried them out, with the door and the time.
Officers and patrol vehicles
RFID badges and tagged patrol units mean every exit and return names the officer, the car and the gear that went with them.
From the door to the shelf
Everything the department buys is tagged and catalogued the moment it arrives from the vendor, so the quartermaster always knows what is on hand and where.
Every Doorway Is a Checkpoint
An RFID reader pair on each side of the door tells Senitron which way a tag passed: into the armory, out of the evidence locker, out to the garage. Every room gets its own overhead antenna, so any item’s last read lights up its room on your floor plan.
- Readers at the armory, evidence intake, evidence locker, sally port and garage bay
- Direction of travel on every read: checked out or returned
- Badges, gear and vehicles read hands-free, without stopping anyone
- Your own floor plan, rooms and logo in the portal
Chain of Custody for Every Evidence Bag
Tag each bag at intake and Senitron writes its history for you: case number, current room, last read and status — In Custody, Out to Crime Lab, Out to Court — with every move recorded against the officer and the time.
- Print and apply RFID evidence tags at the intake counter
- Booked at the sally port, logged into the locker by an evidence technician
- Checked out to the crime lab or court and returned, each step timestamped
- The full history on one page, ready for court or an internal review
An Alert the Moment Evidence Walks Out
The Evidence Locker Exit Monitor flashes the bag that just left on a TV in the evidence room or at the front desk: photo, case number, offense, the officer who booked it, the time and the door. Every open alert stays listed until a supervisor resolves it, and the record shows who resolved it and why. The armory monitor does the same for long guns, with serial, make, model and the assigned officer.
- A sound and an on-screen card for every exit
- Email or text alerts to supervisors
- Every resolution recorded with who and why
Who Left, in Which Car, with What
When an officer walks out of the armory with a duty pistol, Taser, body camera and radio, Senitron records one event: the officer’s photo and badge, each item with its photo and serial number, the door, the time — and the patrol unit and plate as the car leaves the garage. When two officers leave together, both officers and the whole group of items are recorded.
- Exit and return events for every shift, searchable and exportable
- No more paper sign-out sheets at the armory window: the door keeps the log
- A room-to-room breadcrumb trail for every badge and item, by date range
Evidence Room Audits in Minutes, Not a Weekend
Walk the evidence locker with a handheld RFID reader: it reads every tagged bag and box on the shelf at once, without opening anything. Compare the result with the live list for each item type and see exactly what is in custody, out, or out of place. Upload to the Senitron dashboard, review any discrepancies, and export the results for your records.
Find Any Item: Its Room Lights Up
“Where is the spare body camera?” gets answered on the spot. Open any item and its last-read room lights up on the floor plan — a pistol in the armory, a badge in the locker room, a bag in the evidence locker. In the room, the handheld’s Geiger finder beeps faster as you get closer.
The Whole Station on One Screen
Active inventory, open exit alerts at the armory and evidence locker, missing items and every reader, with your department’s own logo and floor plan. Search every serial number by category, officer or case number, with your own column names.
- Live counts by item type for audits and budget requests
- Missing-item reports for anything that drops out of sight
- Every badge, vehicle and item read, kept for investigations and reviews
- Cloud-hosted: nothing for IT to install or run
Start Where the Risk Is, Then Grow
1. Walk the building
Floor plan, choke points and reader placement; your portal set up with your logo and rooms.
2. Armory and evidence first
Tag firearms, less-lethal tools and the evidence locker; readers on those doors; exit monitors on.
3. Badges and vehicles
RFID badges for staff and tags on patrol units, so every exit names the person and the car.
4. Everything else
Radios, body cameras, computers and field gear, tagged on receipt from the vendor.
Police Department RFID: Common Questions
How does RFID evidence tracking work in a police department?
Each evidence bag gets an RFID tag at intake. Readers at the evidence intake, locker and exit doors log every move with the time and the officer whose badge passed with it, so the chain of custody is written for you, from booking to the crime lab, to court and back.
Can RFID tell which officer took a piece of equipment?
Yes. Officers wear RFID badges, so when an officer walks out of the armory or the equipment room with tagged gear, Senitron ties the items to that officer, records the door and time, and logs the patrol unit when the vehicle is tagged too. When officers leave together, both officers and the whole group of items are recorded in one event.
What police equipment can be tagged?
Firearms and patrol rifles, Tasers and less-lethal tools, body armor, body cameras, radios, laptops and drones, field and tactical gear, uniforms, evidence, found property, patrol vehicles and personnel badges.
How long does an evidence room audit take?
Minutes. A handheld RFID reader reads every tagged bag and box on a shelf without opening anything, so an audit that used to take a weekend becomes a walk down the aisles, checked against a live list.
Does it need servers or work from the city IT department?
No. Senitron is cloud-hosted, so there is nothing to install or run on site. Your portal is set up with your logo, floor plan and rooms, and it is ready to use from any browser.
What does it cost, and is there a guarantee?
Software with seven-days-a-week support runs $200 to $500+ per location per month depending on your setup, month to month with no contract. One-time hardware: handheld scanners $1,550 to $3,500, printers $2,000 to $3,500, loss-prevention systems from $2,500, and labels $75 to $110 per roll of 1,000. Multi-location discounts, a price-match guarantee (we match or beat any comparable quote, apples to apples) and a 30-day money-back guarantee.
How quickly can we get started?
Setup and training take about 2-4 hours, done remotely by our US-based team, and hardware usually arrives within days, so most sites are tracking with RFID within a week. Training sessions are recorded and support is unlimited.
