The short answer
You can install a dash cam yourself for ₹0 if you power it from the 12V socket. Paid installation from Qubo, as a reference, costs ₹706.82 for a front camera and ₹1,178.82 for a front and rear setup, including GST. Parking mode needs power with the engine off, which usually means a hardwire kit or step-down cable with a low-voltage cut-off. Of TWM's dash cams, only the A6 has a hardwire cable in the box. TWM installs any of them for ₹990 in most cities.
Fitting a dash cam so it records while you drive is easy. Most are plug and play, and you'll be done before your chai goes cold.
Parking mode is the hard part. The camera needs power when the car is off, and it has to get that power without leaving you with a dead battery on a Monday morning. So our advice splits in 2: do the 12V install yourself, and pay someone for the hardwiring unless you've worked in a fuse box before. This guide covers both, along with what installation costs in India.
What dash cam installation costs in India
There are 3 ways to get a dash cam fitted.
- Do it yourself. No labour cost. You use the 12V socket and tuck the cable into the trim. On most cars this won't power parking mode.
- A brand's installation service. Qubo lists a flat installation and demo charge of ₹706.82 for single-camera dash cams and ₹1,178.82 for front and rear or 3-channel models. Both prices include 18% GST, which puts the base rates at ₹599 and ₹999. Availability depends on your pincode.
- A local car accessory shop. Rates vary by city, shop and car. Get a written quote that says whether it covers hardwiring or only a 12V connection, and whether the kit is included.
The hardwire kit is the cost people miss. If a dash cam ships with only a 12V cable, parking mode means buying a kit separately. Here's how our own range stacks up:
- Hardwire cable in the box: the TWM A6 (₹8,496), for 24-hour parking surveillance.
- Step-down cable needed, not in the box: the TWM R3 (₹4,990), TWM A3 (₹5,990) and TWM S2 (₹4,690). Each records fine from the 12V socket while you drive. The cable is only for recording while parked.
- Always hardwired: the TWM AI Dash Cam (₹13,990) runs from the fuse box on 12V and 24V vehicles, so it's a fitting job from the start.
TWM installs any of them for ₹990 in most cities, and extra charges may apply in remote areas. Those prices are from 8 October 2026 and may change, so check the product page.
Tools you need for a DIY install
- A plastic trim tool, or an old plastic card, to lift panel edges.
- 8 to 10 cable ties or adhesive clips.
- Glass cleaner and a microfibre cloth.
- A microSD card your camera supports, formatted in the camera. TWM dash cams don't include one, and ours take cards up to 256GB.
- For hardwiring only: a hardwire kit or 3-wire step-down cable (in the box only with the TWM A6), 2 add-a-fuse taps that match your car's fuse type, and a circuit tester.
How to install a front and rear dash cam yourself
These steps assume a front and rear camera, such as the TWM S2 or A3, powered from the 12V socket. Do the whole job with the car parked and the ignition off.
Front camera
- Test first. Plug the camera in, start the car and check that both cameras record. It's a lot less annoying to find a fault now than after you've hidden 4 metres of cable.
- Pick the spot. Mount the camera high on the windscreen, behind or just to the left of the rear-view mirror. Keep it inside the wiper sweep and out of your line of sight.
- Stick the mount. Clean the glass, then press the mount firmly in place for 30 seconds.
- Route along the headliner. Push the cable into the gap between the windscreen and the roof lining, working towards the passenger-side corner.
- Go down the A-pillar. Tuck the cable into the rubber door seal that runs down the pillar. Don't pull the pillar trim off (see the safety note below).
- Finish at the socket. Run the cable under the glovebox or along the edge of the dashboard to the 12V socket. Clip any slack away from the passenger's feet.
Safety
Many cars have curtain airbags behind the A-pillar trim. A cable routed across the airbag can get in its way, or be thrown loose when it deploys. Dash Cams Australia advises that DIY installers tuck the cable into the door weather-stripping and leave work behind the pillar cover to a qualified installer. If your pillar trim says "SRS" or "Airbag", treat that as a firm no.
Rear camera
- Mount it. Fix the rear camera at the top centre of the rear windscreen.
- Route the cable. From the front camera, run the rear cable along the headliner on 1 side of the car, tucked into the roof lining and door seals.
- Leave slack at the tailgate. In a hatchback or SUV, say a Baleno or a Creta, leave enough slack where the cable crosses to the tailgate so it can open fully.
- Check the angle. Open the dash cam's phone app, look at the live view and adjust the rear camera until the road behind is level and centred.
TWM dash cams connect over Wi-Fi to the "TWM - Track What Matters" app on Android or iOS, so you can check the live view there. Also read whether dash cams are legal in India before you pick a mounting spot.
How parking mode works
Parking mode keeps the camera watching the car after you walk away. Recording non-stop would fill the card and use too much power, so cameras use lighter methods:
- Impact and motion detection. The camera waits in a low-power state and wakes when the G-sensor feels a knock, or the lens sees movement nearby.
- Buffered recording. Some cameras keep the last few seconds of video in memory, so the saved clip shows what happened just before the trigger as well as after it.
- Time-lapse. The camera records a few frames and plays them back fast. BlackVue's parking mode guide explains that its time-lapse records at 1 frame per second, so a long stretch of parked time fits in a short file.
Our own cameras use different methods, so check which one you're getting:
- TWM A6: 24-hour parking surveillance, powered by the hardwire cable in the box.
- TWM R3: parking monitoring, plus time-lapse recording once you add a 3-wire step-down cable.
- TWM A3 and S2: time-lapse only. They don't wake on motion or impact the way a parking monitor does, and they need a step-down cable to stay powered.
Whichever you pick, the camera needs power from the vehicle to record while parked.
3 ways to power parking mode
1. A 12V socket that stays live
On most cars, the 12V socket switches off with the ignition, and so does the camera. A few cars keep the socket live. Here's a 5-minute test: plug in the camera, switch off and lock the car, then come back and see if it's still on. If it is, parking mode works with no wiring. Nothing protects the battery, though.
2. A hardwire kit to the fuse box
This is the most common method. The A6's hardwire cable works this way, and so does the 3-wire step-down cable the R3, A3 and S2 need, which is a hardwire kit by another name. The kit connects to 2 fuses: one that's always on, and one that's only on with the ignition. That's how the camera knows you've parked.
A good kit has a low-voltage cut-off, so check whether yours does. The R3 and S2 also list low-voltage protection in the camera itself. It watches the battery and switches the camera off before the voltage drops too low to start the car. For scale, a healthy car battery rests at about 12.6 volts, and kits with a cut-off typically let you pick a threshold somewhere between 11.6 and 12.4. Use add-a-fuse taps. Don't cut or splice factory wires.
3. A dedicated dash cam battery pack
A separate battery sits under a seat, charges while you drive and powers the camera when you park. Your car battery isn't touched in parking mode. It costs more, but it suits a new car or one you rarely drive.
Will a dash cam drain your car battery?
While you're driving, no. The alternator powers the camera. The risk is only in parking mode, when the camera draws a small current for hours with nothing recharging the battery.
A car used daily usually recovers that charge on the next drive. Problems start with a car that sits for 3 or 4 days, has an old battery or only does short trips. Without a low-voltage cut-off, a camera on an always-live socket keeps running until the battery gives up.
If the car sits for 7 days or more at a time, lower the parking sensitivity or use a battery pack.
Warranty and insurance: check before you tap wiring
Plugging into the 12V socket doesn't touch your car's wiring. Hardwiring does. Before you hardwire a new car, ask your dealer how fitted accessories affect the electrical warranty. Keep the job reversible: fuse taps, no cut wires, and a note of which fuses you used.
It's also worth asking your insurer whether a fitted dash cam needs to be declared as an accessory on your policy.
When to pay a professional
We'd hand it over in any of these 5 cases:
- You want parking mode and you've never worked in a fuse box.
- Your car has airbags in the A-pillar and you'd need to go behind the trim.
- It's a new car still under the maker's warranty.
- You're fitting a 3-channel system with an interior camera.
- The fuse box is hard to reach, or the manual doesn't label the circuits.
If you buy a TWM dash cam, you can add installation (₹990) to your order, then book a slot on our installation page with your order ID.
A plain 12V install is well within most people's reach. Still choosing? See our best dash cam for cars in India guide, 2K vs 4K dash cams, and Qubo dash cam alternatives, or browse the TWM dash cam range.
Frequently asked questions
How much does dash cam installation cost in India?
A DIY install from the 12V socket costs nothing. As a reference, Qubo charges ₹706.82 for single-camera dash cams and ₹1,178.82 for front and rear models, including 18% GST. TWM charges ₹990 in most cities. Local shops set their own rates, and hardwiring costs more.
Do I need a hardwire kit for parking mode?
On most cars, yes, or a dedicated battery pack. The 12V socket usually switches off with the ignition. A live socket works, but with no low-voltage cut-off. Of TWM's dash cams, only the A6 includes a hardwire cable. The R3, A3 and S2 need a step-down cable, sold separately.
Will a dash cam drain my car battery?
Not while you're driving. In parking mode it can, especially if the car sits for days. A hardwire kit with a low-voltage cut-off, or a separate battery pack, prevents that.
Where should the rear camera wire go?
Along the headliner and door seals on 1 side of the car, then across to the top of the rear windscreen. Leave slack where it crosses to a tailgate.
Can I install a dash cam in a car under warranty?
A 12V socket install doesn't touch the car's wiring. For hardwiring, ask your dealer first and use fuse taps instead of cutting wires, so the change can be reversed.
