Unfortunately, some mental health professionals claim videotaping is tantamount to an invasion of privacy.  And unfortunately, you have no control over whether videotaping takes place.

The argument is specious.  If an accusation, whether true or false, is made, that which  the child says at the interview will be spread to literally dozens of people.  That spreading becomes similar to the parlor game where the words told by the child to the first person do not resemble the words spoken by the last person to hear them.  Only a tape, audio or audio/videotape, can repeat the child's words without distortion or contamination.
 
Even assuming -- but without conceding -- that audio- or videotaping is an invasion of privacy, it is still in the best interests of the child to sacrifice privacy in order to safeguard (1) that the child not be coerced by improper interviewing techniques into wrongly accusing an innocent person of sexual abuse or rape and (2) that justice be done.

The guilt the child would feel later from testifying to a falsehood would surely be worse than perhaps having had his or her privacy invaded.

Search for articles re the use of videotaping in sex abuse cases.  Do not hesitate giving them to your attorney.  Must lawyers do not have such articles in their files unless they have had a case on point.
