Ganz Vm300 Viewfinder For Cctv Surveys - Any Good?

[JasonOfOz]

HI Everyone,

 

Was thinking about getting one of these.

 

Does anyone use one?

 

Is it any good or just an unnecessary gadget?

 

Of course I could just pace out the distances and FOV to calculate the lens size but I thought this would be great as you can look through the lens to really confirm what the client will see.

 

Any thoughts?

James,

is a "live viewer" the same as the VM300?

 

If yes then is the reason you don't use one because you know what you're doing and are confident that the lens you specify will do the job or is it because of another reason?

Sorry Oxo,

 

I'm not sure what you mean here, could you explain in more detail?

[Oxo]

Camera suppliers give shots of "items" at differnt distances with a different lens,

 

For example a screen shot at 25mts with a 8mm then another the same with a 12mm  ect ect.

Then some let you connect to their DVR and use PTZ so you can show the client with your BB/IP/S3
