Dashcams in South Africa, explained.

Most private owners are well served by a dual front-and-rear camera with genuine night vision and parking mode, budgeting around R2,000–R4,000 all-in including installation. Connected and cloud cameras add a monthly fee for off-site footage. Beyond that, four details separate a camera that produces usable evidence from one that produces a smeared rectangle where a number plate used to be.

Night performance, which is not the same as resolution

Resolution is what the box advertises; low-light sensitivity is what decides whether you can read a plate at night, and the two are not the same thing. A 4K camera with a small, cheap sensor can easily produce a worse night image than a good 1080p unit, because at night the limiting factor is how much light the sensor gathers, not how many pixels it divides that light into. Most incidents you will actually want footage of - hit-and-runs, attempted smash-and-grabs, disputed night-time collisions - happen in exactly the conditions where a cheap sensor gives up. If you compare on one specification only, compare on that.

Parking mode needs power the ignition does not supply

Parking mode is the feature people most want and most often do not get working. A camera plugged into the cigarette lighter loses power when you switch the car off, so it records nothing while parked - which is when a great many incidents happen. Genuine parking mode requires a hardwire kit to the fuse box, with voltage cut-off protection so the camera stops drawing current before it can flatten the battery. If parking footage is the reason you are buying, budget for the hardwire install rather than treating it as optional.

Heat, and why capacitors beat batteries here

A car parked in the South African sun gets hot enough to matter to the electronics inside it. Dashcams are built either with a small lithium battery or with a supercapacitor to hold enough charge to close the file safely on shutdown. Lithium cells degrade faster in sustained heat and are the most common cause of a camera that worked for a season and then started failing to boot or corrupting files. Supercapacitor models cost a little more and tolerate heat far better. For a car that lives outdoors here, that is usually the right trade.

The memory card is a consumable, not an accessory

A dashcam writes continuously and overwrites itself for the life of the card, which is a workload ordinary microSD cards are not designed for. A standard card in a dashcam typically fails within months, and it tends to fail silently - the camera appears to be recording and the footage is not there when you need it. Use a high-endurance card rated for continuous video, size it to how much history you want, and check that footage still plays back every month or two. It takes a minute and it is the difference between having evidence and believing you had it.

What a dashcam will not do

A dashcam documents. It does not recover. If your car is taken, footage from inside it leaves with the car - which is the problem cloud-connected cameras exist to solve, and why they carry a monthly fee. A dashcam is also not what an insurer means when it asks for tracking: the two products answer different questions, and having one does not satisfy a requirement for the other. If theft and recovery are your concern rather than disputed liability, that is a vehicle tracking question, and the two are often bought together for that reason.
