How to Install a Dash Cam in Your Car? A Driver’s Guide

A properly installed dash cam gives you clear video footage, a stable power connection, unobstructed driver visibility, and a clean cabin without loose cables.  

If you are a driver in the Philippines planning to buy a dash cam and set it up yourself, this guide walks you through the entire process, from choosing the right mounting spot to wiring everything neatly.

Read on to learn how to install dash cams.

Where to Mount a Dash Cam?

Before learning how to install dash cams, decide the mounting position, which affects video coverage, driving safety, and legal compliance.

1. Philippine Dash Cam Installation Laws

The Philippines does not have a specific law about dash cam installation. However, Republic Act No. 10913, also known as the Anti-Distracted Driving Act, requires that no device or object should obstruct the driver's line of sight. [1] The Land Transportation Office (LTO) also enforces rules against windshield obstructions.

This means your dash cam fitting must keep the device out of your direct field of vision.

2. Front Camera: Behind or Below the Rearview Mirror

The best position for a front dash cam is directly behind or below the rearview mirror. This location offers three advantages:

• Unobstructed driver view: The camera sits in a zone already blocked by the mirror, so it does not create an additional blind spot.
• Wiper coverage: Placing the camera within the windshield wiper's sweep area ensures that rain, dust, and debris are cleared from the lens's field of view.
• Centered perspective: A center-mounted camera captures balanced footage of both sides of the road, which is more useful for incident documentation.

3. Rear Camera: Top Center of the Rear Windshield

For a rear camera, mount it at the top center of the rear windshield. This position captures the full view behind your car. Mounted at the top center, the angle covers both side lanes, giving you more complete footage when reversing or changing lanes.

Do not mount it at the bottom of the rear windshield. The trunk lid can block it, and the footage will have gaps.

Step-by-Step: How to Install Dash Cams

How to install dash cams? Here are three installation methods: front camera setup, rear camera setup, and hardwiring for parking monitoring.

1. Front Camera Installation

Step 1: Mounting Position

Hold the dash cam against the windshield in the target area, behind or below the rearview mirror. Turn the camera on and check the live preview.

Adjust the angle until the horizon line sits roughly in the upper third of the frame. This framing captures the road ahead and enough of the sky to handle varying light conditions.

Step 2: Clean and Secure

Clean the dust, oil, or residue on the windshield mounting area with an alcohol wipe or glass cleaner. Allow the glass to dry completely and then attach the electrostatic sticker to the installation position.

If your dash cam uses an adhesive pad, peel off the backing and press the dash cam firmly against the center of the sticker for at least 30 seconds. If it uses a suction cup, press the cup flat against the sticker.

Adhesive mounts generally hold more reliably in the Philippine climate, where heat and humidity can weaken suction cups over time.

Step 3: Routing the Cable (Cigarette Lighter Socket)

Then route the cable neatly to avoid dangling wires:

• Tuck the cable into the gap between the windshield and the roof liner.
• Run the cable along the A-pillar, which is the vertical frame between the windshield and the front side window. Most A-pillar covers can be gently pried open to hide the cable underneath.
• Continue routing the cable along the dashboard edge or under the floor mat until it reaches the power port.
• Plug the power cable into the cigarette lighter socket.
  

Use the cable clips included with most dash cams to secure any exposed sections.

Note: Do not interfere with the airbags. The A-pillar usually contains side curtain airbags. Do not run the cable across the airbag deployment path. The correct approach is to follow the existing wiring harness in the A-pillar. If you cannot determine where an airbag is located, consult the vehicle owner's manual

2. Rear Camera Installation

A rear camera records traffic behind your vehicle and is especially useful for documenting rear-end collisions and reversing incidents. Rear camera installation takes slightly more effort because the cable must travel the length of the cabin.

Step 1: Mounting Position

Attach the rear camera at the top center of the rear windshield, using the same cleaning and mounting steps as the front camera. Angle the lens so that the road behind you fills most of the frame, with a small portion of your trunk or tailgate visible at the bottom for reference.

Step 2: Routing the Cable

The rear camera connects to the front unit through a cable that typically runs along the ceiling headliner:

• Start at the rear windshield and tuck the cable into the headliner seam.
• Run it along the roof to one side of the cabin, following the edge where the headliner meets the side panels.
• Continue forward along the headliner or the top of the side panels until the cable reaches the front dash cam. 

Keep the cable path along one side of the vehicle. This reduces visible wiring and prevents the cable from hanging in the way of passengers.

Step 3: Connecting and Securing

Plug the rear camera's cable into the designated port on the front dash cam unit. Once connected, check the front unit's display or app to confirm that the rear camera feed is active. Secure any loose cable segments with adhesive clips.

How to Hardwire a Dash Cam?

Hardwiring connects your dash cam directly to the vehicle's electrical system through the fuse box. This is necessary for two key features:

• Parking monitoring, which keeps the camera recording when the engine is off, 
• Multi-camera setups, which draw more power than a cigarette lighter port can supply. 

Hardwiring gives your dash cam a stable, always-on power source without occupying the accessory port. You will need a hardwire kit. Most reputable dash cam brands sell hardwire kits designed for their products.

Note: If you are not familiar with your vehicle's electrical system, do not attempt hardwiring on your own. Incorrect fuse connections can damage the dash cam, blow fuses, or interfere with critical vehicle electronics.

Step 1: Route and Hide the Cables

The hardwire routing path is the same as the cigarette lighter route. The difference is the endpoint: the fuse box instead of the cigarette lighter. The fuse box is generally under the dashboard or in the engine bay. Check your vehicle manual to confirm the location. Run the cable down the A-pillar to near the fuse box.

Step 2: Locate the Fuse Box and Test

Open the fuse box cover and identify two types of fuse slots:

• ACC (Accessory power): Supplies power only when the car is on. 
• VCC (constant power): Supplies power whether the car is on or off. This fuse powers the parking monitoring function.

Use a circuit tester to confirm these two fuses. Touch the tester probe to the exposed metal end of each fuse with the ignition turned off. A VCC fuse will show voltage; an ACC fuse will not. Start the car and test again. The ACC fuse should now glow.

If you do not have a circuit tester, check your vehicle's user manual. It usually includes a fuse box layout diagram indicating the location and function of every fuse.

Step 3: Connect the Hardwire Kit and Ground Wire

• Remove the identified ACC and VCC fuses from the vehicle’s fuse box using a fuse puller or pliers. 
• Next, use the fuse tap, which has two fuse positions: one for the original fuse and one for the dash cam fuse. Place the original fuse in the slot closest to the power source, and the new fuse (included in the hardwire kit) in the other slot.
• Connect the red wire to the ACC fuse tap and the yellow wire to the VCC fuse tap. 
• Last, insert both fuse taps into their corresponding fuse-box positions and make sure they are firmly seated.

After that, connect the ground wire. Attach the ring terminal on the ground wire to a bare metal bolt on the vehicle's chassis. A common grounding point is an existing bolt near the fuse box or under the dashboard. The bolt must make direct contact with bare metal, as painted or coated surfaces will not provide a proper ground.

Step 4: Test the Installation

Turn the car on and confirm that the dash cam powers up. Then turn the car off and verify that the camera enters parking monitoring mode, if your model supports it.

Remember to choose dash cams with intelligent power management, which can monitor battery voltage and stop power delivery when the battery reaches a preset protection level. This is intended to reduce the risk of excessive battery discharge during parking monitoring.

FAQs

1. Can I Install a Dash Cam Myself?

Yes. A basic front dash cam installation using a cigarette lighter power source requires no technical expertise. You only need to mount the camera, plug in the power cable, and tuck the wire out of sight. Rear camera setups require a bit more patience for cable routing.

Hardwiring demands electrical knowledge. If in doubt, ask a professional installer for help.

2. Will Hardwiring a Dash Cam Drain the Car Battery?

It can, but quality hardwire kits, such as DDPAI dash cams, prevent this. A properly installed hardwire kit includes a low-voltage cutoff module that automatically disconnects power to the dash cam when the battery voltage drops to a preset threshold. This protects your battery from draining to the point where the engine cannot start.

3. Is Hardwiring a Dash Cam Worth It?

Hardwiring is worth it if you need parking monitoring or run a multi-camera setup. Parking mode allows your dash cam to record incidents, such as hit-and-run collisions, vandalism, or break-in attempts, while your car is parked and the engine is off.

For drivers who only need basic recording while driving, a standard plug-in installation is sufficient and easier to manage.
