The Surveillance Camera Commissioner has also recently consolidated and re-launched his guidance materials into a toolkit: https://www.gov.uk/government/news/launch-of-the-online-toolbox . Whilst the SCC's statutory remit is largely limited to central and local government, his toolkit has a number of practical resources which are useful for private and NHS providers,  housing associations and other private businesses. 

Finally, the ICO's Code of Practice (https://ico.org.uk/media/1542/cctv-code-of-practice.pdf) and checklist (https://ico.org.uk/for-organisations/resources-and-support/data-protection-self-assessment/cctv-checklist/) provide material specifically geared towards Data Protection legal compliance.
