When it's your word against theirs, you'll have the footage. It reads the license plate front and back, even at night, starts when the car starts, and has no battery inside to swell or die.

The rear camera had him reversing into me, clear as day, plate and all. Not another word from his insurer once they saw it.Mike R. · Columbus
Life with a Halden
It comes on with the car and goes off with the car. Here is what changes the day you fit it.
Passed the test, first car in the driveway, and you lie awake at night. It records every journey without them doing a thing, front and back.
The four-way stop, the on-ramp, the car that pulled out. You have the clip with the plate on it, not a story the insurer splits down the middle.
At night and in the rain
Most dash cams look fine in daylight. Then it is dark, wet and the plate is a smear. This is the bit that matters.
A 4K front camera with a Sony Starvis 2 sensor, made for low light. Plates stay readable under streetlights, in the rain and in oncoming headlights.
The 2.5K rear camera sits inside the top of the back window. Shunted at the lights, reversed into in a parking lot: it is on the clip too.
Drag the slider. Left is a typical cheap dash cam at night. Right is the Halden Duo 4K.
“At night you may as well not even have it.”What owners say about the dash cam they had before
The question everyone asks
It is the number one worry, and the cheap ones earn it. Here is the straight answer.
The hardwire kit watches your car battery. If it drops low, it cuts the power to the camera, so there is always enough left to start the car in the morning.
Most dash cams have a small lithium battery that swells on a hot dashboard and dies in a year or so. This one has a capacitor instead. Nothing to bulge, nothing to replace, and it works from -4 °F to 158 °F.
Plug it into the 12V outlet instead. It records whenever the car is running and switches off when you do. You can add parking mode later.
Out of the box
No drill, no garage and nothing to buy. Here is the whole job, rear camera included.
013 minStick it behind the mirrorWipe the glass, press on the static sticker and stick the mount on top, just behind the rear-view mirror. The camera clicks onto the mount and sits out of your eyeline.
027 minTuck the cable awayPush the cable into the gap at the edge of the headliner with the trim tool in the box, down the pillar by the door seal, and plug it into the 12V outlet. No cable hanging anywhere.
0310 minFit the rear cameraStick it inside the car at the top centre of the back window. Tuck its 20-foot cable along the headliner to the front and plug it into the side of the camera. On a hatchback, the cable goes through the rubber gap at the hinge of the liftgate.
041 minStart the carIt is recording, front and back. Pair your phone in the app once and you are done. Fit the hardwire kit for parking mode later, or ask any car electronics installer.
Stuck on your car? The quick-start guide is in the box, the online manual shows every step, and a real person answers any hour: tell us your make and model.
The rest of it
Parking mode
With the hardwire kit fitted, it keeps watch after you lock up. It films a frame a second while nothing happens, so the card does not fill up, and starts full recording the moment something bumps the car. That clip is locked, so it is never recorded over. No more coming back to a dent and no idea who did it.
Out of your way
Plenty of dash cams talk to you, beep at every speed camera and light up the windshield after dark. This one sits behind the mirror where you cannot see it, the screen switches off after a minute, and it stays quiet unless you ask it something. You forget it is there, until the day you need the clip.
On your phone
Connect your phone to the camera's own Wi-Fi in the free app, watch the clip and save it. Then send it by email or text. GPS stamps your speed and where you were on every clip, so nobody can argue about where or how fast.
How it works
A dash cam only has one job: to be recording when it happens. Here is how the Halden makes sure of it.
No button to press and nothing to remember. The moment the ignition goes on, it is recording, front and back, and it switches off when you do. It records in a loop, so the newest footage is always there.
A bump or a sudden stop locks that clip, so it is never recorded over. Press one button to lock a clip yourself, for the car that cut you up.
With the hardwire kit in, it keeps watch after you lock up and wakes the moment something bumps the car, then switches off before your car battery runs low.
Covered for two years, with 60 days to try it on your own car.
An installer's view
Nineteen years fitting dash cams and fixing the ones that went wrong. This is the one he tells people to buy.
Two jobs come through my van every week. A dash cam that flattened someone's battery, and a dash cam that wasn't recording when they needed it. The first is nearly always a cheap hardwire lead with no cut-off, or a camera with a lithium battery that has swollen in the summer. The second is usually a cheap card that has given up. The Halden sorts both. There is no battery inside to swell, the hardwire kit cuts the power before your car battery gets low, and it starts every single time the ignition goes on. Most people can do the basic fit themselves in twenty minutes. It's the one I tell people to buy.

What it really costs
Three ways to get a front and rear dash cam in your car, and what each one costs.
A front camera, the rear camera bought separately, the hardwire kit, then $100 to $200 for the install. And a morning in the waiting room.
Fine on the box. Then the plate is a blur at night, the battery swells on the dashboard in July, and the app never connects.
4K front and 2.5K rear, a plate you can read at night, no battery inside to fail, and the hardwire kit for parking mode in the box. Install it yourself in twenty minutes. Covered for two years, with 60 days to try it. Shipped free.

Guy reversed into me at the lights, then told his insurer I'd gone into the back of him. I had the clip on my phone before I got home. Front got his plate, rear got him reversing. His insurer accepted it in a week. Last time this happened they called it 50/50.
Our Ellie passed her test in August and I haven't slept right since. My husband fitted this in her Civic on the Sunday. It comes on by itself when she starts the car, so there's nothing for her to remember. Best money I've spent this year.
Came back to the grocery store parking lot to a dent in the door, third time this year. This time parking mode had it. Silver Camry, plate clear as anything. Sent it to my insurer and kept it off my record.
Wife bought it for my birthday. I'm 67 and useless with gadgets, so I was dreading it. The kid next door had it fitted in twenty minutes and showed me the app once. I haven't touched it since. It just comes on with the car.
Hardwired it with the fuse taps in the box, about an hour with the rear cable run neatly. Night footage is really good, plates readable under streetlights and in the rain. Took me two goes to pair the app the first time. Fine since, and the screen goes off so it's not lit up at night.
I'm not techy at all and did front and back myself in about twenty minutes. The little plastic tool pushes the wire into the headliner so you can't see it. My dad came round to check my work and couldn't find anything to fix.

Common questions
No. The hardwire kit keeps an eye on your car battery. If the voltage drops low, it switches the camera off, so there is always enough left to start the car. If you would rather not use parking mode at all, plug it into the 12V outlet instead. Then it records whenever the car is running and stops when you turn it off.
Most people fit it themselves in about twenty minutes, rear camera included. Stick it behind the mirror, tuck the cable into the headliner with the trim tool in the box, and plug it into the 12V outlet. The hardwire kit for parking mode takes longer, and any car electronics installer can fit it in under an hour if you would rather not.
It sticks inside the car, at the top centre of the back window, so nothing is fitted outside. Clean the glass, stick it on, and tuck the 20-foot cable along the headliner to the front with the trim tool, then plug it into the side of the front camera. On a hatchback or an SUV, the cable goes through the rubber gap at the hinge of the liftgate, so it never gets trapped. If the rear picture shows upside down, flip it in the menu in one tap.
The 20-foot cable is long enough for most cars up to about 4.20 feet long, which covers most sedans, hatchbacks and small SUVs. If your car is longer, such as a big SUV or a minivan, send us your make and model first.
Yes. Factory privacy glass makes the night picture a little darker, but plates behind you stay readable under streetlights and headlights. If your tint is very dark aftermarket film, stick the camera on a clear part of the glass if there is one.
Most newer cars have a rain or lane sensor there. Stick the Halden just to the passenger side of it, as high as it fits. It is small, 3.3 in wide, so it still sits out of your view.
The hardwire kit plugs into your fuse box with fuse taps, so no wires are cut and it comes out again in minutes. A dash cam fitted this way is not a change to the car itself. If you are unsure about your own policy, it is a quick question for your insurer when you renew.
Yes. It starts the moment you start the car, without a button. It records in a loop, so the newest footage is always kept, and a bump locks that clip so it is never recorded over. You can also press one button to lock a clip yourself.
Plugged into the 12V outlet, it switches off with the engine. With the hardwire kit fitted, it goes into parking mode when you turn the engine off and keeps watch until you come back, or until your car battery gets low.
No. In parking mode it is filming the whole time, a frame a second, so the car pulling in is on the clip. The moment something bumps your car, it switches to full recording and locks that clip.
That is what it is built for. The front camera is 4K with a Sony Starvis 2 sensor, made for low light, and the rear is 2.5K. Plates stay readable under streetlights, in the rain and in headlights.
You need a microSD card. Ours comes formatted and ready to record: pick 64GB or 128GB when you order. You do not have to buy ours. Any good U3 card from 32 to 256GB works. Cheap slow cards are the usual reason a dash cam stops recording, so use a decent one.
No laptop needed. Connect your phone to the camera's own Wi-Fi in the free app, watch the clip and save it to your phone. Then send it to your insurer or the police by email or text, from the roadside if you need to. If you prefer a computer, the USB card reader in the box takes the card.
It is small and sits behind the mirror, where it is hard to spot from outside. If you park somewhere you are worried about, it unclips from the mount in a second and goes in the glove box.
Yes, dash cams are allowed in every state. Some states are strict about anything on the windshield, so fit it behind the mirror, out of your view of the road, which is exactly where it goes.
Some insurers give a small discount and many do not. What it does is show what really happened. When it is your word against theirs, the footage is what stops a split-fault call and keeps it off your record.
It records sound by default, so you hear the horn or the bang. You can turn sound recording off in the menu or the app any time.
You have 60 days to try it and send it back for a full refund. After that it has a 2-year warranty with no registration: if it stops working, it is repaired or replaced, free. You can also add the Lifetime Warranty for cover for as long as you own it. Questions any time: [email protected].
Stop hoping the other driver tells the truth. Stop coming back to dents with no idea who did it. Stop worrying about the new driver in the family. The Halden Duo 4K records every journey front and back, reads the plate at night, and has no battery inside to fail. Fit it yourself in twenty minutes.
