4. Application note for wireless HD cameras 

4.1 Introduction 

 

The typical cameras that were used today in the broadcast section are triax cameras 
which are used for wireless applications as well. Mostly the customers can not afford 
an additional HD camera with Battery mounts for wireless applications. 

 

As an example we take the Sony 1450, 1500 or 1550 camera which are the most 
frequent cameras in the broadcast section. 

 

Caution 

 

The original cameras have no mount and no support for batteries  

 

Also we as BMS do not recommend screwing a bracket on a 
camera for a day by day use. Therefore we are trying to use 
original Sony brackets or for other cameras other original 
brackets which can support a adaptor for wireless applications 
 

 

 

 

 

Sony camera without V-mount bracket
