Telonixium 4K Wi-Fi Eyepiece Camera review
A 4K Wi-Fi electronic eyepiece camera with an 8 MP sensor, a rotatable IPS screen, a 2000 mAh battery, microSD support to 512 GB and a universal groove for eyepieces of 23 to 60 mm.
The universal locking groove takes eyepieces from 23 to 60 mm, the widest range on this shelf. Like the smaller Telonixium, it films what an eyepiece shows rather than replacing it.
Two figures for one screen
The bullet heading says a rotatable 2.5-inch IPS screen; the text beneath says 2.8 inches. The listing never reconciles them.
Eight megapixels, or sixty-four
The sensor is 8 MP with 4K video. The “up to 64 MP image capture” figure can only be interpolation; it adds pixels, not detail.
Battery, storage and app
A 2000 mAh battery, microSD up to 512 GB, and the free XDVPRO app for iOS and Android with time-lapse and timed shooting, over Wi-Fi to two devices within 32 ft.
Price and availability
On November 7, 2026, Amazon.com listed it at about $160 from a third-party seller.

What observers ask about this one
Is it 2.5 or 2.8 inches?
The bullet's heading says 2.5 inches and its text says 2.8. The listing does not settle it.
Is it really 64 MP?
The sensor is 8 MP. A 64 MP file from it can only be upscaled, adding no detail.
What does it fit?
A universal groove takes eyepieces from 23 to 60 mm, on telescopes, binoculars, monoculars and microscopes.
