1. What in-vehicle video connects
In-vehicle video covers buses, taxis, freight trucks, and ride-hailing cars. Over 4G, a DVR (vehicle hard-disk recorder), an NVR (network video recorder), ADAS (advanced driver assistance), and DSM (driver status monitoring) send their data up. The vehicles move, so 4G is what holds coverage across the road network. SimtoLink provides 4G for transport companies, with a shared data pool and an API into the telematics platform.
2. Typical uses and what the link must do
Buses, taxis, freight, and ride-hailing do not need the same bandwidth or the same response time:
Buses and passenger coaches
A bus DVR sends several video streams and the GPS track over 4G for live monitoring, event recording, and arrival forecasts. Monthly use is about 3–8GB.
Freight and logistics trucks
A freight DVR sends video, the track, and load over 4G for monitoring on the road, fatigue alerts, and electronic waybills.
Taxis and ride-hailing
Taxi and ride-hailing terminals send video, the track, and orders over 4G for service oversight, complaint evidence, and safety protection.
ADAS and DSM
ADAS (forward warning) and DSM (driver monitoring) send alarm events and stills over 4G for active safety.
3. What the connection has to deliver
- Coverage that moves: Bus, taxi, and freight routes change. 4G has to cover the road network, and multi-operator selection keeps a weak stretch usable.
- Several video streams: DVR and NVR video, event stills, and clips have to come back live or close to live. Bandwidth and data use are both high.
- Tracks and location: The GPS track and the live position keep going up, for dispatch, geofences, and arrival forecasts.
- Active safety: ADAS forward-collision warnings and DSM fatigue detection have to go up promptly, for active safety and oversight.
- Platform link: Connect the telematics platform and the video platform for multi-vehicle management, event search, and evidence that meets the rules. The API closes the data loop.
4. Which IoT SIM card to choose
Bandwidth and data use differ by vehicle and by how much video you keep. Weigh both before you order. The table is a starting point:
| Use case | Recommended radio | What matters |
|---|---|---|
| Bus and coach DVRs | 4G | Several video streams, GPS tracks, about 3–8GB a month |
| Freight and logistics trucks | 4G | Video, tracks, load, monitoring on the road |
| Taxis and ride-hailing | 4G | Video, tracks, orders, service oversight |
| ADAS/DSM terminals | 4G | Alarm events, stills, active safety |
5. Data use
About 2–10GB a month per device, mostly video from several cameras. Pool by vehicle type, keep 20%–30% spare, and use VPDN to keep the link private.
6. Security and compliance
Driving video and track data put this at a high security level. You need a VPDN private network, TLS, and an IP allowlist. SimtoLink supplies VPDN, a dedicated APN, and real-name registration together.
7. What SimtoLink recommends
For in-vehicle video, use 4G IoT SIM cards in the vehicle DVR, ADAS, and driver-behavior analysis. Commercial vehicles need several video streams back live, over 4G with no wired drop. You get 99.9% network availability, a high-data plan, multi-operator network selection, and an API into the telematics and video platforms.
8. How to roll it out
Rollout steps:
Choose by vehicle type and the road network, prove mobile coverage in the target area, set VPDN and APN with an allowlist, and alert at 80% of the plan. SimtoLink can run the work from survey to go-live. Ask for a plan written for that fleet.
