While the DR750X Plus series are very similar in appearance and functionality to the DR750X series, the DR750X Plus does introduce fundamental changes and upgrades. These changes and upgrades include a better image sensor, the freedom to tag on a secondary camera to the single-channel, and the consolidated firmware.
The improved Sony STARVIS™ CMOS sensor is probably the main change brought by the X Plus series. Some users have reported that the X Plus uses the Full HD ultra-low light Sony IMX 327 image sensor. While we haven’t yet confirmed that with BlackVue, if it’s indeed true, then you can expect to see an improvement in the ability to preserve details in extreme lighting conditions.
But the one upgrade that we are more excited about is adding a secondary camera to the 1CH version. Before the X Plus series, BlackVue designed the 1CH models as a 1CH only, without a secondary camera port. In other words, if you want to go from a 1CH to a 2CH system, you will have to purchase the 2ch system as a whole. But now, with the X Plus series, BlackVue added a secondary camera port to the front camera so you can get the 1CH model first and upgrade it to a 2-CH at any later time just by plugging in the camera you need - rear, interior infrared or the waterproof exterior. And because of this scalability, both the 1CH and the 2CH X Plus share the same firmware.
In other words, if you are looking for better image quality or the option to switch from a 1CH to a 2CH, then we strongly recommend you consider upgrading to the DR750X Plus series. But if you are simply looking for improved Cloud connectivity or parking mode functionality, you won’t gain much - these features remain the same.
