Installing a dash cam sounds more technical than it really is. Most drivers can handle it at home in less than an hour with the camera, a memory card, and the cable in the box. This guide walks you through where to mount it, how to power it, how to hide the cable, and when hardwiring is worth paying a professional for.
Can You Install a Dash Cam Yourself?
Yes. Most single dash cams plug into the 12V socket and stick to the windscreen. You can fit one at home in under an hour. You only need the camera, a memory card, and a little care with the cable. A rear camera takes a bit longer to route.
Start by choosing your setup. A front-only camera is the simplest option. A dual setup needs a second cable running to the rear glass. If you’re still deciding, read our guide on front vs rear dash cams first.
Lay everything out before you start. Keep the camera, mount, cable, and card on the passenger seat so you are not climbing in and out of the car.
Where to Mount It So It Won’t Block Your View
Mount the camera high on the windscreen, near the rear-view mirror. That gives you a clear view of the road and keeps it out of your eyeline. Clean the glass first so the mount holds in the heat. For a rear camera, place it high on the back window.
Wipe the glass with a dry cloth where the mount will sit. If the surface is greasy, the mount can slip once the cabin gets hot. Press it firmly for a few seconds.
Keep the camera behind the mirror line so it does not block your view. In Sri Lanka, a blocked windscreen is also a safety issue in heavy traffic.
Angle the lens slightly downward so it catches the road and the car ahead. Check the live view on the screen before you lock in the position.
12V Socket vs Hardwiring to the Fuse Box
A 12V plug is the easiest choice. The camera powers on with the engine and switches off when you park. Hardwiring connects it to the fuse box instead. That keeps it running for parking mode. It is fiddly, so many drivers leave that part to a professional.
Most dash cams in Sri Lanka come with a 12V adapter in the box. Plug it in and the camera runs whenever you drive. For most people, that is enough.
Hardwiring takes power straight from the fuse box. It lets the camera record while the car is parked and hides the power cable completely.
It also needs the correct fuse and a solid earth. Get it wrong and you can drain the battery. If you are not sure, ask a fitter to handle that part.
Hiding the Cable Cleanly Around the Windscreen
Tuck the cable into the trim around the windscreen. Run it up to the roof lining, then down the pillar to the socket. Use the soft trim gaps so nothing hangs loose. A neat run looks better and keeps the cable out of the airbag path.
Push the cable gently under the headliner edge, then guide it down the A-pillar on the passenger side. Avoid the pillar that contains the curtain airbag if your car has one.
Leave a little slack near the mount so you can adjust the camera later. Not sure which card to buy first? See our dash cam memory card size guide.
Test everything before you finish. Start the car and confirm the camera records, then press the trim back into place.

FAQs
Can I install a dash cam myself?
Yes. A front-only dash cam plugs into the 12V socket and sticks to the windscreen. Most drivers can fit one at home in under an hour. A rear camera takes a little longer because you need to route a second cable.
Is there a dash cam without wires?
No dash cam is fully wireless because it needs constant power to record. The neatest option is hardwiring, which hides the cable in the fuse box. A 12V plug is the simplest wired setup.
Does a dash cam have to be wired into the car?
Not always. A 12V socket plug works for most drivers and needs no wiring. You only need hardwiring if you want parking mode to record while the car is off.
