Two cameras, one tank, four switches.
This is the only unit with ports, and the ports run out. What it costs to own is mostly what gets plugged into it and how long a fitter spends doing that — so the two hours on the price list describe one configuration, not yours.

Configure one vehicle
The price list says 2 hours, and for a camera truck it is exactly that. The same unit on the 3-compartment reefer takes 3 h 18 min and uses 4 of its 4 switch inputs. Put everything on one vehicle and it runs out of switch inputs before it runs out of anything else.

Calibration is a fill, not a setting
A probe measures how high the fuel stands. What you want is litres, and tanks are not boxes: they have baffles, rounded ends and a step where the chassis rail runs past.
So the fitter fills a 600-litre tank in 10 steps of 60 litres, waits 2 minutes at each for the surface to stop moving, and writes down what the probe says. Pumping at 40 litres a minute, plus the settling, comes to 35 minutes. It is the table that makes the fuel page's ±1% true, and the reason to book the install at the end of a shift, when the tank is close to empty anyway.

What the card holds
Two cameras at 2 Mbps record 17.6 GB over a 10-hour shift. The 512 GB card keeps 31 days of that for a vehicle working six days a week, which is where the plan's 30 days come from.
A double-shifted vehicle fills the same card in 13.5 days. Neither card reaches its headline number on doubles, and we would rather say so here than when you go looking for footage from day twenty.
| Card | Duty | Days kept | Sold as |
|---|---|---|---|
| Standard card 512 GB · Command plan | One shift, six days a week | 31.5 | 30 |
| Double shift, every day | 13.5 | 30 | |
| Extended storage 2 TB · Add-on | One shift, six days a week | 123.1 | 90 |
| Double shift, every day | 52.8 | 90 |
After formatting reserve. Only the clips around events leave the vehicle; the rest is retrievable on request until it is overwritten.
Why this unit has the fast radio
A 20-second clip from both cameras is 10 MB. The radio in every other unit is built for positions, not pictures, and would take 4 min 27 s to send it. A day's clips, 80 MB, would keep it transmitting for 36 minutes.
A clip that arrives after the phone call about the incident is not much use in the phone call.

What owning one actually involves
The vehicle is off the road for it
2 h for a camera truck, 3 h 18 min for the reefer, 5 h 18 min for everything at once. Fitters work your night shift, but a vehicle that works nights gives up a shift.
The calibration belongs to the tank
Replace or repair the tank and the table is wrong. Recalibrating is another 35-minute fill, and until it is done, fuel alerts on that vehicle are switched off rather than left to be wrong.
Four inputs means four
A 3-compartment reefer with a switch on each door and one on the fridge uses all 4. A panic button on the same vehicle means two doors share an input, and you lose which one opened.
A cabin camera is a policy before it is a product
Drivers need to know what it records, what leaves the vehicle and who can ask for it. The dashcam page sets out what we built and what we deliberately did not.
