Optical zoom is supported by the MV22 indoor camera and the MV72 outdoor camera.
The camera itself will be fixed in your chosen position, at install time, so while you can zoom in and out 'straight ahead', you won't be able to optically zoom in on a particular location, like you would with a PTZ camera. You can digitally zoom in on a particular part of the field of view though.
More importantly, having a fixed field of view allows for a number of powerful features which PTZ cannot cater for; the ability to reliably detect motion, for example - to quickly find and distinguish between historic events. You're also always sure of having coverage of the area you are interested in, at any one point in time. (no good having a PTZ if it's pointed the other way from the activity you want to look back on). No PTZ = far fewer moving parts = fewer camera failures too. Having the right blend of cameras usually removes the need for PTZ.
You may also be interested in the MV32 fisheye camera, which provides 'digital PTZ'. This allows you to cover 360 degrees, from a ceiling, but focus back in on the area of interest, after the event, with the footage 'de-warped' from its original fisheye type view. No optical zoom with a fisheye though, of course.
I think maybe you should research the general Meraki approach to security cameras too - Meraki needs no NVRs..! Meraki simplicity = MV cameras + the Meraki Dashboard & nothing else to buy or manage. https://meraki.cisco.com/products/smart-cameras/
Ultimately, I'd recommend getting in touch with your Meraki rep or Cisco partner to maybe free trial some cameras for your use cases. You can access these via 'Get a demo' on the webpage above.
