Where the platforms overlap

For a Texas police department evaluating CAD and RMS, Thin Line and ARMS belong in the same consideration set.

Both cover the fundamentals in one suite: dispatch, the incident record, field access, NIBRS reporting, court processing of citations and jail custody. Both host their cloud offerings on Microsoft Azure Government. Both are on the Texas DPS list of vendors actively submitting NIBRS data with Texas agencies.

That overlap is why a chief already talking to ARMS should also look at Thin Line, and why this page doesn't pretend the products are unrelated.

Where ARMS stands out

ARMS has real strengths. Consider ARMS when you want a national vendor with decades in public safety, campus or school public-safety features, parking enforcement in the same system, an on-premise records option, or support and implementation commitments published up front.

A national footprint and long track record

ARMS says more than 1,000 agencies in 48 states use its software, backed by more than 37 years in public safety. That's a broad reference base for agencies that want a vendor with a long history.

Campus, K-12 and healthcare public safety

ARMS publishes solutions for higher-education, K-12 and healthcare public-safety departments, including automated Clery Act reporting. For campus police, or cities that share records with a school district police department, that focus can matter.

More modules around CAD and RMS

ARMS publishes Parking Management, Automatic Vehicle Location, a dedicated Property & Evidence module, and a reporting library with hundreds of pre-built reports. At Texas Police Chiefs Association events it has also promoted AI-powered report transcription. Thin Line doesn't claim equivalents for parking or AVL.

Jail through ATIMS

In February 2026, ARMS announced it had acquired ATIMS, a jail management provider used by several large sheriff's offices. ATIMS continues as a dedicated corrections platform within the ARMS portfolio.

Deployment choice

ARMS SaaS runs in a single-tenant Microsoft Azure Government environment. ARMS also sells In-Synch RMS as an on-premise product for agencies that want to host their own records system.

Published support and implementation commitments

ARMS publishes 24/7/365 live support and a typical 60–90 day implementation that includes project management, data migration and training.

Where Thin Line stands out for Texas agencies

Consider Thin Line when Texas is the whole job, not one of 48 states. Thin Line builds RMS and CAD around Texas workflows, keeps you close to the people who develop and support the product, and lets you connect Court, Code Enforcement or Jail alongside police work.

Texas is the home market, not one region of many

ARMS serves municipal, campus, K-12 and healthcare agencies across the country. Thin Line was built in Lubbock for Texas police departments, cities and counties. Texas NIBRS work includes Texas-specific requirements beyond the federal NIBRS file. If Texas reporting is a deciding factor, ask both vendors which Texas-specific segments, validations and certification workflows they support today.

TLETS is live, built into the platform

Thin Line's TLETS integration runs in the core platform, so driver license and vehicle queries work across CAD, RMS and mobile for TLETS terminal agencies today, and results integrate with Thin Line master records. Criminal history queries and non-terminal agency support are coming. Ask each vendor which TLETS query types are live today, and in which modules.

Police, court and code enforcement can share the same community story

ARMS publishes Courts & Processing, which moves citations from CAD or RMS into court case management. Thin Line also connects Court Management with police records. Thin Line also sells Code Enforcement, so the city can share people, places and vehicles across police, court and code enforcement work. In September 2025, The Slatonite reported on Slaton's Thin Line agreement. Code Enforcement Officer Rebecca Britton said she was happy with the system and described how it interlinks with the police department.

Licensing by agency and product

Thin Line licenses software by agency and product, not by officer count. ARMS describes site licensing for its SaaS offering and, in some materials, user tiers. Both avoid simple per-officer seat math. Ask both vendors to quote the same scope and show how adding users, modules or departments changes the contract.

Built in Texas. Close enough to answer.

Fewer layers sit between your agency and the people who configure, train and change the product. Implementation, training and support come from a Texas-based team that stays involved after go-live.

The question is not which platform is better

ARMS and Thin Line offer overlapping suites, but they're built around different markets. The useful question is which operation you need to run, and whose home market it is.

ARMS may fit when you need

  • A national vendor with a long public-safety track record and references in many states
  • Campus, K-12 or healthcare public-safety features, including Clery reporting
  • Parking management or AVL in the same system
  • An on-premise RMS option
  • Jail management from ATIMS, a corrections platform used by large sheriff's offices
  • Published 24/7/365 support and a stated 60–90 day implementation window

Thin Line may fit when you need

  • A vendor whose home market is Texas police departments, cities and counties
  • Texas-specific RMS and CAD workflows, including Texas NIBRS / TIBRS
  • Municipal court and code enforcement connected to police records when the city runs those operations
  • Jail alongside CAD and RMS on one platform
  • Licensing by agency and product
  • Close access to the Lubbock team developing and supporting the product
  • TLETS driver license and vehicle queries built into the platform (TLETS terminal agencies today)

The right choice depends on your agency's operation, requirements and priorities.

Vendor evaluation

Questions to ask both vendors

Don't take our word for it. Ask both vendors the same questions.

A useful comparison isn't a feature checklist. It's a set of questions whose answers, for an agency your size, often show the differences on their own.

  1. 1How much will implementation and historical-data conversion cost?
  2. 2How long does a typical implementation take for an agency our size?
  3. 3Who will train our officers and dispatchers?
  4. 4Who do we call when we have a problem?
  5. 5Is pricing based on users, modules, a site license, or something else?
  6. 6Which Texas-specific reporting requirements are supported today?
  7. 7Which TLETS query types are live today, in which modules, and which are on the roadmap?
  8. 8Can you provide references from Texas agencies like ours?
  9. 9What happens to our historical RMS and CAD data?
  10. 10Which integrations are included versus separately licensed?

About this comparison

Questions agencies ask about this comparison

Which ARMS products does this page compare?

ARMS's cloud CAD/RMS suite and the modules ARMS publishes around it: Courts & Processing, ATIMS JMS, Parking, Property & Evidence and Reporting. ARMS also sells In-Synch RMS as an on-premise records product. Thin Line is compared as one platform with RMS, CAD, Mobile Citations, Court, Jail and Code Enforcement.

Does Thin Line include 911 or NG911 call handling?

Thin Line CAD is dispatch software. Thin Line doesn't claim a PSAP or NG911 call-handling product. ARMS doesn't highlight 911 call handling in its public product list, so ask the vendor what it supports.

Does this page compare prices?

No. Thin Line licenses software by agency and product, not by user count. ARMS doesn't publish prices and describes site licensing or user tiers. Ask both vendors for a scoped quote.

Are Thin Line and ARMS listed by Texas DPS for NIBRS?

Yes. Texas DPS lists both Thin Line Software and End2End Inc. (ARMS) among vendors actively working with Texas agencies to submit NIBRS data. That listing reflects live NIBRS submission and certification work with a Texas LEA. It isn't a DPS certification, approval, endorsement or CJIS-compliance statement for either vendor.

Does Thin Line integrate with TLETS?

Yes. TLETS is integrated into Thin Line's core platform. Driver license and vehicle queries are live across CAD, RMS and mobile for TLETS terminal agencies today; support for non-terminal agencies is coming soon. Criminal history queries are also coming. TLETS access still runs under your agency's own DPS agreements and operator certification.

Is Thin Line Software the same company as ThinLine Radio?

No. Thin Line Software (thinline.software) builds RMS, CAD, court and jail software for Texas public-safety agencies. It isn't affiliated with ThinLine Radio or other unrelated brands that share similar names in search results.

Is Thin Line an alternative to ARMS for Texas police departments?

Thin Line and ARMS overlap in RMS, CAD, mobile, court and jail. Thin Line is built around Texas agencies and also offers code enforcement connected to police and court records. Agencies that need campus Clery reporting, parking management, AVL or an on-premise RMS should weigh those requirements when comparing.
