BJ72 and Cynap are both oriented to the commercial field and can be widely used in corporate offices and school classrooms with powerful and stable functions.

However, the B72 is obviously richer in terms of functions, has the capacity for large-scale deployment and management, and also has the ability to perform multi-screen interaction in smart classrooms, and the price is cheaper.

So the cost performance of BJ72 is more high.

We’ve got a Cynap Pure already and it’s really awesome – your details and comparison are not accurate and we only paid 11,500 RMB. Better check the correct WolfVision specs here: https://wolfvision.com/vsolution/index.php/en/presentation-systems/cynap/cynap-pure
