Kingslim 4K Front and 1080P Rear Dual Dash Cam

Kingslim E4 is a compact front-and-rear dash camera system that captures 4K footage at the front and 1080P at the rear with robust night vision and app control for fast downloads.

This dual-channel dash cam records both directions simultaneously to preserve complete incident context. Designed for everyday driving and parked-vehicle monitoring, the E4 combines a 1.5-inch IPS display and a low-profile, behind-mirror mount so it stays out of the way while recording continuously. Built-in safety features like a G-sensor, loop recording and time-lapse help protect footage and save storage, and the no-battery architecture increases reliability in extreme temperatures.

How clear is the footage from the front and rear cameras?

The front lens captures 4K (3840×2160) video with a wide 170° field of view and an f/1.8 aperture for improved low-light performance. The rear camera records 1080P with a 150° angle so you get sharp images of license plates and road signs from both directions.

• Front: 4K 3840×2160, 170° wide view, f/1.8 aperture for night clarity
• Rear: 1080P, 150° field of view to cover lanes behind you
• 6-layer glass optics to reduce glare and improve contrast
• Enhanced night vision for clearer low-light captures

What protections stop important clips from being lost?

The Kingslim E4 locks critical clips automatically when a collision or sudden brake is detected by the built-in G-sensor. Loop recording runs continuously, overwriting the oldest non-protected files so you never run out of space, and time-lapse mode reduces storage use while parked.

• G-sensor triggers 20-second emergency lock on impact
• Loop recording cycles recordings to maintain continuous capture
• Time-lapse parking recording conserves SD card space
• Optional hardwire kit enables 24-hour parking monitoring (sold separately)

How do I access and manage recorded videos?

Connect your smartphone to the dash cam using the Kingslim app over 2.4GHz or 5GHz Wi‑Fi. The E4 supports fast 5GHz transfers so you can preview and download clips in seconds without removing the SD card. A 64GB card is included and the system supports up to 256GB for extended recording.

• Built-in Wi‑Fi: 2.4GHz and 5GHz support for faster downloads
• Kingslim app for iOS and Android to stream, save, and share footage
• Comes with a 64GB SD card; expansion up to 256GB supported
• Small 1.5" IPS screen for quick local playback and settings

Why does the no-battery design matter for reliability?

Instead of an internal lithium battery, the E4 uses a no-battery configuration that avoids swelling and sudden battery failures in heat or cold. That allows stable operation from -4°F to 150°F and extends the device lifespan compared with battery-powered dash cams.

• No internal lithium battery prevents thermal swelling problems
• Rated to operate across -4°F to 150°F extreme temperatures
• Designed for long-term durability and 24/7 reliability
• Hardwire kit available to enable continuous parking mode

Who is this for: Drivers who want high-resolution, dependable dual-channel coverage for daily commutes, rideshare use, or fleet vehicles will benefit most from the Kingslim E4. It’s suited to people who need crisp daytime and nighttime footage, easy smartphone access to videos, and a compact dash cam that installs discreetly behind the rearview mirror. Choose the E4 if you prefer robust incident protection and faster 5GHz transfers without the maintenance concerns of battery-based dash cams.
