Compact cam

Your 2nd camera and the option for a 3rd

Cobra includes a second camera so you can record the inside of your vehicle or record your rear view — a smart addition for ride-share drivers or for fleet vehicles. If you'd like to use your second cam as a rear-view and still have an interior cam, this system also allows for the integration of a third Full HD Cabin-View camera (not included).


Cobra goes above and beyond standard dash cam functionality by incorporating Alexa compatibility into the SC 400D. With a Bluetooth connection to your vehicle's radio and a Wi-Fi connection to your phone, you can chat with Alexa on your phone via the SC 400D's built-in mic and hear the results over your vehicle's audio system. Ask questions, play music, find restaurants, and more with Alexa.

Drive Smarter® app compatibility

Cobra made the SC400D with Bluetooth for easy integration with your phone. Using data from your phone's cellular plan, this cam can geo-tag your footage with time, date, location, and speed information. Additionally, your live connection with Cobra's online Drive Smarter community will give you a heads-up if speed cameras, red light cameras, or live police locations are in play nearby. Remotely access all your recorded video on Drive Smarter cloud storage and easily generate incident reports when you need them.

Mount it in a convenient spot

These compact cameras and their adhesive-backed mounts won't crowd your field of vision when you're driving. Both fully automated cameras will start recording once the engine is turned on and will stop when the engine is turned off. Their loop-recording function documents any incidents on the road. And if you're involved in an accident, the SC400D's built-in G-Sensor will detect sudden acceleration or a collision, then save the critical footage.

More details on the Cobra SC 400D

Product Research


Overview: The Cobra SC 400D dash camera kit provides a continuous recording of both the front- and rear-facing cameras, and can even warn you of upcoming red light cameras, speed cameras, and police enforcement locations via the iRadar app. A built-in G-sensor can detect impacts and will automatically protect the footage around that time. Built-in GPS will also embed location, time and date information into the recorded video, protecting your side of the story in the event of an accident.

4K HD Video: The SC 400D dash camera kit can record video from both the front and rear cameras, or just from the front. The front-facing camera can record video in resolutions as high as 3840x2160 @30fps (4K) for crystal clear recordings. Additional resolutions of 2560x1440 @30fps and 1620x1080 @30fps (1080p) are available for gaining increased storage capacity. Designed for set-and-forget operation, the unit will turn on and start recording each time power is applied to it, or by pressing and holding the top-panel On/Off button. When power is removed, the dash-cam will safely stop recording and shut down. The camera's 3" HD LCD touchscreen can be used to playback recorded video, as well as provide on-screen settings and options.

Continuous Loop Recording: Video footage is recorded to the included 32GB micro-SD card (expandable to 256GB) in a continuous loop fashion, with the oldest footage getting overwritten when the card becomes full. Footage is stored in 1, 2, or 3 minute clips, making it easier for reviewing and transferring to a computer for editing. A built-in microphone allows the surrounding audio to be recorded along with video.

  • Emergency Recordings: If an impact or collision is detected, that recorded video will be saved in the Emergency Recordings file and won't be overwritten by the Continuous Loop Recording mode.
  • Emergency Record Button: An Emergency Record button on the side of the camera lets you manually capture and save video that won't be overwritten by the Continuous Loop Recording feature.
  • Photos: An on-screen "camera" icon lets you easily take a snap-shot of the camera's current view, which is stored in the camera's Photo Folder.

Rear-View Camera: The included HD rear-view camera is designed to mount on the inside of a rear window, providing a view of the road and objects behind you. The camera features an integrated window-mount with an adhesive backing. A proprietary 16' cable is included for connecting the rear-view camera to the dash camera.

Optional 3rd Camera: The SC 400D includes a second 2.5mm input for connecting the FV-CV1 Cabin-view Camera (sold separately). This add-on accessory lets you record the view inside the vehicle, making it an ideal choice for ride-share and commercial vehicles.

Wide View: Both of the included front- and rear-view cameras can each provide a 140˚ wide-angle view of the road and peripherals.

G-Sensor: The SC 400D features a built-in accelerometer that can sense an impact or collision, and will automatically protect video footage around the time. The G-sensor features 3 sensitivity settings, with 1 being the most sensitive and 3 the least, or can be turned off completely.

Parking Mode & Motion Detection: The Cobra dash camera can monitor your vehicle while parked, if connected to a constant power source. The camera will monitor its surroundings, while the G-sensor can detect an impact to the vehicle. If motion or an impact is detected, the SC400D will save 1 min video clips as long as the activity is being detected.

Note: Parking Mode & Motion Detection are only available if the camera's included lighter-adapter power cord is connected to a power socket that has constant power, providing +12V when the vehicle is Off. An optional Cobra Hardwire Kit or Dash Cam Hardwire Kit (sold separately) can be used to connect to the fuse box or OBD-II port for +12V power.

GPS: A GPS antenna, built into the dash camera's mounting base, lets you have your exact location, time, and date stamped to the camera's video footage.

Lane Departure & Collision Warning: The Cobra dash camera can provide audible and visual warnings if you approach a lane boundary, or if you are rapidly approaching another vehicle or obstacle in the road ahead.

Microphone & Speaker: The Cobra dash-cam features a built-in speaker and microphone, allowing audio to be recorded along with video, if desired. Integrated Voice Commands and Voice Announcements allow for hands-free camera operation.

  • Voice Commands: This "hands free" feature lets use verbal commands to operate certain functions, including: "Front Video On", "Rear Video On", "Record Video", "Lock Video", "Screen On", "Screen Off", and "Take Photo".
  • Voice Announcements: When your connected smartphone is running the Drive Smarter app, the camera can give you verbal warnings provided by the app, such as approaching red-light and speed-cameras, user-reported police and radar use in the area, accidents, and more.

Alexa Compatible: The Cobra SC 400D works with your phone to bring you the convenience of Alexa to your drive. The built-in microphone in the dash-cam is specially tuned to "hear" the Alexa Wake command and invoke Alexa services on your phone. This feature is certified with both Apple and Amazon, allowing the camera to automatically reconnect to Alexa when you get in the car and respond, even when in the background on your phone.

Micro-B USB: A micro-B USB port lets you connect the SC 400D to your computer for downloading captured video clips.

Dual-Band Wi-Fi: The SC 400D features built-in dual-band WiFi for connection the cloud for video management and software updates.

Drive Smarter App: Downloading the Drive Smarter App to your smartphone, available from the Apple App and Google Play stores, lets you connect to the SC 400D via Bluetooth, letting you view, edit, and share captured video footage from your smartphone.

  • Cloud Video Management: The Drive Smarter app stores your video footage safely in the cloud and lets you view your camera's footage from your phone without a physical connection to the camera or your computer. Previously shot video can be downloaded to the phone for viewing, as well. This can be especially helpful in the event of an accident, by letting you easily share captured video footage with your insurance provider.
  • Integrated Driver Alerts: Drive Smarter integrates alerts from the Cobra community of drivers, letting you receive updates on road conditions and potential hazards, as well as sharing information with the Drive Smarter community.
  • MayDay: Cobra's MayDay feature lets you create an emergency contact that can be notified when the camera's G-sensor detects a severe impact or collision. It will automatically upload your location and a MayDay notice to the assigned contact.
  • Incident Reports: The Drive Smarter App can help streamline the accident claims process with the Incident Reports feature which compiles relevant information taken from the dash cam video footage in a summarized format that you can send out.
  • Device Settings: The Drive Smarter app lets you manage device settings and features, from setting up your profile to customizing app alerts, as well as receiving over-the-air firmware updates.

5 questions already asked

I do a lot of night driving and want to be able to record at night. Do the front and rear cameras record well at night? If I understood correctly the optional interior camera does infrared/night vision but the others do not.
nicholas  Feb 07, 2024

Greetings Nicholas. Thank you for your question. Front camera will not have Infrared lighting, but at night with the headlights on, the camera would not need that. All they need is the vehicles headlights to get a great image. The optional FV-CV1 interior add on camera does have infrared to record inside the vehicle at night.

Does the lane departure warning activate when intentionally changing lanes with the turn signal activated?
chris  May 04, 2023
1 answer
Greetings Chris, and thank you for your question. This dash cam for the most part is a dash cam with an extra feature of lane departure. It does not know whether you are intentionally changing lanes or by accidently drifting into another lane. Its not in any way connected to the turn signal to know the difference. It is however a feature that can be disabled, or enabled depending on the user.
hogan  May 05, 2023 (Staff)
Does it record speed with the video?
prefer  Apr 27, 2022
1 answer
This can record the speed as part of a watermark that it stamps onto the recorded video
jason  Apr 30, 2022 (Staff)
Can the monitor be turned off? so it doesn't bother you at night.

The screen can be turned off while the unit is on and working.
