I'm hoping someone can help me with my employers request.
She has a large seminar room with 2 65" 4k TVs on the wall. The room has no windows so she would like me to stream video from a camera outside to the tvs.
I'm an electronic engineer but sadly know nothing of cameras.
Price is not too much of a consideration, and suggestions would be much appreciated!

cheap IP camera outside and a NVR plugged into the TV would do it, but you may have non removable text overlays for the time and stuff on the picture.

Our school has just started to trial Vivi to wirelessly connect to our projectors (after having poor reliability with apple tvs) has the ability to display splash screens or to stream videos directly to it.  If you had a camera streaming to a web address this could work.  I think the cost is around $100 per device.  Has the added advantage of being able to use it for conferences etc.

 

seems to be designed more for education purposes but ...

Just a couple of things to consider.

 

The lens focal length and sensor size need to give a natural perspective. Many cheaper cameras are fitted with wide angle lenses.

 

It should be pointed out that the image on the screen will never replicate a window because when the people inside the room move, the view does not change so it will look unnatural.

Hi - depending on distances involved, doorways, etc - another option could be to run an HDMI cable directly from a camera pointing at what you want. A lot of cameras (both DSLR's and lower-end point and shoots) have either a mini or micro HDMI, so if the camera was powered via mains it would feed an image out through it's HDMI port.

 

Of course you could also just run a movie file of an pre-recorded outside view or an even better view (tropical island, volcano, Eiffel Tower - various 'stock' footage is available online).

 

It'd be good to hear what your results end up being.





Cheers,
