The DDPAI Z40 is a dual-channel dash camera system designed to monitor both the front and rear of your vehicle. The front camera captures footage in 2.7K resolution using a Sony IMX335 sensor and an F/1.8 aperture lens, which helps maintain clarity in various lighting conditions across a 140° field of view. To keep a watchful eye on what is happening behind you, the system includes a 1080P rear camera that can be rotated 360° to adjust the angle to your liking. Technical reliability is handled by a supercapacitor, which makes the device more resistant to extreme heat and cold than traditional lithium batteries. For data security, the D²save technology integrates NAND Flash with a MicroSD card (supporting up to 256GB) to ensure emergency backups of front-facing footage are preserved. You can manage your recordings, update firmware, and view clips through the DDPAI app via 2.4GHz Wi-Fi, while the built-in GPS automatically logs your speed, location, and travel track. Driving safety is supported by the Sense Reality 2.0 and Realcube image technologies, along with an ADAS feature that alerts you when a vehicle in front starts moving. If you need constant protection, the 24/7 parking mode with low-voltage protection allows the camera to record while you are away, provided a hardwire kit is used. A 2.0-inch IPS screen on the unit provides quick access to settings, and the G-sensor automatically locks 10-second video clips during sudden impacts to prevent them from being overwritten.
