Expansion Hardware
IOX Add-Ons
Sensors, cameras, and third-party hardware that plug into your GPS tracking device's IOX expansion port.

Updated August 1, 2026
IOX is the platform's expansion ecosystem: a hardware port on every GPS tracking device that accepts a growing range of first-party and third-party add-ons, cameras, temperature sensors, RFID readers, and more, sold through the High Point GPS add-on library. High Point GPS helps fleets choose and install the right IOX add-ons for their specific use case, from cold-chain temperature monitoring to driver ID.
Specs
- Compatibility
- Plugs directly into the IOX port on the GPS tracking device and the rugged model
- Options
- Cameras, temperature sensors, RFID/driver ID, and more via the High Point GPS add-on library
Highlights
- Expand a single GPS tracking device instead of installing separate standalone hardware
- Wide range of first- and third-party options through the High Point GPS add-on library
- High Point GPS scopes and installs the right add-on for your use case
One Port, Growing Over Time
The value of IOX isn't any single add-on, it's that a fleet's hardware needs rarely stay fixed. A fleet that starts with core GPS tracking often discovers a specific problem six months in, unresolved cold-chain disputes, unverifiable incident claims, unclear driver identification across a shared vehicle pool, that a targeted IOX accessory solves without replacing anything already installed.
Because the expansion port is already present on every standard and rugged GPS tracking device, adding that accessory later is a much smaller project than it would be if the base device had to be swapped out or a second standalone system installed alongside it. The GPS tracking device becomes a platform to build on rather than a fixed, one-time hardware decision.
Matching the Add-On to the Actual Problem
The High Point GPS add-on library's range of IOX options is wide enough that the harder part usually isn't finding an add-on, it's identifying which specific problem is actually worth solving with hardware. A fleet with occasional cold-chain disputes needs a temperature sensor; a fleet with driver-pooled vehicles and unclear who-was-driving questions needs RFID or NFC driver ID; the two problems look similar from a distance but call for different hardware entirely.
That's the scoping work High Point GPS does before recommending or shipping anything: matching the accessory to the specific operational pain point a fleet is actually experiencing, rather than defaulting to whichever add-on is easiest to install or most commonly requested elsewhere.
Frequently asked questions
What can I connect through the IOX expansion port?
Cameras, temperature and cold-chain sensors, RFID/driver-ID readers, and other first- and third-party hardware from the High Point GPS add-on library, all plugging into the same GPS tracking device rather than requiring separate standalone installs.
Can I add IOX accessories after the initial installation?
Yes. IOX add-ons can be added later without replacing the base GPS tracking device, so you can start with core tracking and expand as specific needs come up.
Does every IOX add-on work with every GPS tracking device model?
Compatibility varies by specific add-on and device model. High Point GPS confirms compatibility for your fleet before recommending or shipping a specific IOX accessory.
