I work for the Police and part of my job is to serve additional evidence on CPS. Normal procedure dictates that following charge, the Judge sets the date that papers have to be served on the Defence. 'Papers' means basically all the evidence/material that the CPS are planning to use to prosecute you that the police have obtained. Any non sensitive unused stuff is listed on a form called MG6C which is a list of the unused material. This list is then served on the defence after being checked by CPS. The defence have the right to have copies/inspect any of these items which they feel will either undermine the prosecution case or assist the defence. The police have nothing to hide, they have a legal duty to disclose anything which could assist you/undermine the case and could face criminal charges if they intentionally withold such material.
If the CCTV etc that you mention is actual used evidence and has been seized/obtained by the police then your solicitor is entitled to a copy. What is your court date for, is it the actual trial, is it a Plea and Case Management Hearing (PCMH)? If it's the trial then your case could be adourned. If it's the PCMH then the judge will set the date for service of papers then and your case will be adjourned.
