Hi Shemang,
What sort of training are you after regarding your security guards?
If it is to enable them to comply with the Psira grading, you would be beter off contracting a school leaver and getting them to work through the Psira booklets.
If it is for customised operating procedures, you would be better off creating your own video. And in fact it would be cheaper to set up a powerpoint presentation and to screen that.
However, my experience has shown that very few (if any) video training modules are accredited training mechanisms, and so you would (once again) gain better value from structured unit standard based face to face interventions rather than passive video screenings.
To this end, any of the many security training providers should be able to help.
Your post does not indicate the purpose of such training - be warned that SASSETA nor SAQA would recognise video presentation as a developmental intervention, and in fact from a business perspective it is simply a legit 'time off' period.
Hope this helps
Bryan
