Vibration feature...

The RC400UW keyfob camera has a vibration feature to discreetly let you know when you have activatde a certain setting such as starting video recording or taking a quick photo.  Of course, the vibration feature can be switched on or off to suit your requirements.

128G micro SD card supplied...

A 128G micro SD card is supplied with the covert camera but you can use up to 256G.  The 128G card will hold over 4 hours of video footage and so is usually more than adequate for this portable camera system.

This 4k keyfob camera has WiFi too...

Another excellent feature of this camera is that it's WiFi enabled.  This means that if you're within close range (up to about 5m) of the camera you can view live footage and alter settings via the app on your smart phone.  You can also download recorded video too.

Time & Date stamped recorded footage...

From within the app you can synchronize the cameras time and date with that of your phone and so all recorded footage and photos will have the time and date stamp.  This can be useful if the recordings are ever needed for evidential purposes.

Is 4K really that much better than HD?

More advanced screens with 4K HDR meet these standards and have a typical resolution of 3840 x 2160 pixels, around four times than the traditional HD amount.

Basically, 4K devices provide four times the normal pixels, improving the picture quality.

Can the human eye see any difference between 1080p and 4K?

The human eye’s ability to discern the difference between 1080p and 4K largely depends on viewing distance and screen size you are viewing on.

In certain situations, especially on larger screens or when sitting closer to the display, the eye can certainly perceive a difference, with 4K delivering a clearer, more detailed picture.

So the winner is...

Leaving quality aside, 4K looks better as it reduces the chance of colour banding. So your set colours will be captured in far more detail compared to 1080p. Even the smallest of gradual colour changes will be captured almost as good as how you would see it in person.
