Boifun 2K WiFi baby monitor: Baby 6T, 2TM and 4TM
The Boifun 2K WiFi range is for parents who want to watch their child from a phone, in addition to the monitor supplied with the camera. The catalog keeps three families, Baby 6T, Baby 2TM and Baby 4TM, which all list a finer image than the models without WiFi. This page compares them before you open the page of the one you are interested in.

Prices were recorded on amazon.com on October 11, 2026 and can change with promotions. The 4TM has no amazon.com price on that date, so its cell shows a dash: that is a limit of the snapshot, not a statement that the model is unavailable. The spec values are the seller’s; a “Not disclosed” cell means the information is missing from its page.
What sets each family apart
- The Boifun Baby 6T: 5-inch screen, 2K image, 2.4 GHz WiFi with an app or a direct connection without WiFi, 3,000 mAh battery.
- The Boifun Baby 2TM: the same 5-inch screen, a listed 3 MP sensor, 2.4 GHz WiFi and a local monitor, 17 hours of battery life listed.
- The Boifun Baby 4TM: 5.5-inch LCD screen, 4 MP image, dual-band WiFi or a local monitor, up to 23 hours listed.

What WiFi brings, and what it asks for
According to the sellers’ pages, these models offer a dual connection: the monitor on one side, the app on the other. Add to that recording on an SD card (up to 128 GB listed), cloud storage listed, and motion, crying and noise detection. All of it is presented as listed: neither the effectiveness of the detections nor the smoothness of the app was checked here.
A connected device also calls for some care: a strong password, updates, an up-to-date home network. The topic is covered without drama in the guide on baby monitor hacking.
What if I want two cameras?
Each family exists in a two-camera variant (Baby 6T-2, Baby 2TM-2, Baby 4TM-2), presented on the page of its family. The page on Boifun split screen baby monitors gathers them.
WiFi or not: where is the right choice?
If the app does not appeal to you, a simpler model may be enough: see the non WiFi baby monitors from Boifun. To decide calmly, the guide on WiFi or no WiFi baby monitors sets out the criteria.
