What does the GPS tracker and sensor selector do?
Tracking quotes are hard to compare when each vendor proposes a different device with a different set of sensors. Before you ask for prices, settle what each vehicle needs: a GPS tracker, plus the sensors and accessories for the data you want to see.
This tool turns your vehicle groups and needs into that list. It gives three results:
- Kit per vehicle group: the items one vehicle needs and the total for the group.
- Fleet kit list: the quantity of each item for the whole fleet, ready to send to vendors.
- Vendor questions: the inputs each device must offer and up to 10 questions to send with your request.
The tool names device types, not brands or models, and gives no prices, so any vendor can quote against the same list.
What inputs do you need?
| Input | Where to find it | Tip |
|---|---|---|
| Vehicle groups and counts | Fleet register | Put vehicles that work the same way and carry the same equipment in one group. |
| Where the vehicles work | Routes and sites | Choose remote areas when vehicles spend hours without mobile coverage. |
| Fuel tanks, compartments and doors | Vehicle specifications or the body builder | Count per vehicle: a tractor with two tanks needs two fuel sensors. |
| Camera channels | Your safety policy | Each view, such as road, driver, side or rear, takes one channel. |
| Drivers to identify | HR or driver list | One ID card or key per driver, including relief drivers. |
How does the tool choose the GPS tracker and sensors?
Each need maps to one device or sensor type. The types come from the Safee platform's user guides.
| Need | What goes on the vehicle | Applies to |
|---|---|---|
| Location (always) | GPS tracker wired to the vehicle power | Every powered vehicle. A trailer is identified through the tractor's tracker. |
| Remote areas | A satellite device as a second unit (Safee Satcomm works with Orbcomm and Iridium devices) | Groups set to remote areas |
| Fuel level and theft | One fuel level sensor per tank (analog, digital or BLE), or fuel data from the CAN bus where the vehicle gives it | Vehicles with fuel tanks entered |
| Load weight | Analog weight sensors or a KIMAX weight set | Trucks, trailers, reefer trucks and tankers. For a tanker, the platform can turn weight into a liquid amount. |
| Temperature and humidity | One sensor per compartment, wired to a tracker input or BLE | Vehicles with compartments entered |
| Cargo doors | One door sensor per door: a digital input or a magnetic BLE sensor | Vehicles with doors entered |
| Driver identification | An iButton or RFID reader in each vehicle and one card or key per driver | Powered vehicles |
| Driving behavior | Harsh braking and acceleration are reported by the tracker; a seat-belt signal wired to a digital input | Powered vehicles (no seat-belt input on motorbikes) |
| Video | A mobile video recorder (MDVR) with one channel per camera, and the cameras | Vehicles with camera channels entered |
| Engine data | A CAN bus connection | Powered vehicles except motorbikes |
| Remote immobilization | A relay on a tracker output | Powered vehicles |
| Trailer pairing | A trailer ID tag (1-wire iButton), or the serial number of the KIMAX controller, read by the tractor's tracker | Trailers |
| Panic button | A button wired to a digital input | Powered vehicles |
| Heavy equipment | A digital input wired to the machine's work signal (equipment activity status) | Heavy equipment, always |
| Saudi Wasl linking | No extra device: the platform sends vehicle status, location and weight to Wasl | Check your activity's requirement with TGA |
Inputs each device must offer
Sensor inputs can be analog, digital or BLE, depending on the sensor. The table gives the most any one vehicle in the group needs; ask each vendor to confirm the device, with its add-ons, offers them.
Worked example: 40 vehicles in three groups
The default values are an example: 20 delivery vans in the city with one tank, 12 reefer trucks on highways with one tank, two compartments, one door and two cameras, and 8 long-haul tractors in remote areas with two tanks and two cameras. The needs are fuel, temperature, doors, driver identification, driving behavior and video, for 50 drivers.
- Every vehicle gets a GPS tracker: 40 trackers. The 8 tractors in remote areas add 8 satellite devices.
- Fuel sensors: 20 × 1 + 12 × 1 + 8 × 2 = 48. Temperature sensors: 12 × 2 = 24. Door sensors: 12.
- Driver ID: 40 readers and 50 cards or keys. Seat-belt inputs: 40.
- Video: 20 recorders and 40 cameras on the reefer trucks and tractors.
- In total, 322 devices and parts of 10 types, of which 68 are devices that report data. A reefer truck's device needs 2 digital inputs, 3 sensor inputs, an ID reader port and 2 video channels.
How do you read the results?
- Kit per vehicle group shows what one vehicle carries. Check it with the people who run those vehicles.
- Fleet kit list is the quantity to ask every vendor to quote. Ask for a price per item so the offers line up.
- Inputs per vehicle tell you whether one device is enough or the vendor must add an expansion module.
- Notes flag needs that no group can use, such as temperature with no compartments entered.
How do you use the list when buying tracking?
- Send the same list to every vendor: it makes the offers comparable. Compare them line by line with the Tracking Quote Comparison Tool.
- Check the running cost: devices are only part of it. The GPS Tracking Cost Calculator adds subscriptions and installation.
- Write a full request: the Fleet Management RFP Builder covers the software and service requirements around the hardware.
- Accept the installation: test each device and sensor with the GPS Tracker Installation Acceptance Checklist before you sign off.
Assumptions and limits
The list names device and sensor types, not models, and gives no prices. The installer confirms the final device for each vehicle after seeing it. Device models and their availability differ by country, so confirm what is available in your country with the Safee team. Sensors, doors and cameras on trailers are not counted, because they depend on how each trailer is wired. Wasl requirements differ by transport activity: check yours with TGA and the Wasl Preparation Checklist. Install an immobilizer so the engine is cut only when it is safe.
