U26902: Unit Descriptor:
Maintain the operational performance of CCTV systems
Maintain the operational performance of CCTV systems This unit defines the national standard of occupational competence for making sure CCTV systems and equipment are working as required. Before you begin to check the performance of CCTV systems and equipment, you should make sure that this would not compromise your organisation’s operational commitments. You should then carry out sufficient valid tests to determine how well the system is working. You might need to make adjustments with the system or equipment or identify which system component is impairing the overall performance. Or you might have to contact someone else to rectify the unacceptable performance. You should be able to give sufficient operational information to the relevant person to help them rectify problems with CCTV systems or equipment. You could also be required to assist them, in line with your responsibility and authority. You should therefore understand the operational requirements of CCTV systems and equipment, as well as how to test operational performance. You should also understand CCTV terminology, sufficient to describe system performance, tests and faults.
ELEMENT

UNDERPINNING KNOWLEDGE AND SKILLS Confirm operational performance of CCTV systems 1. The limits of your responsibility and authority to maintain the performance of CCTV systems, including tests and adjustments. 2. The functional operation of the CCTV systems and equipment that you are required to maintain. 3. How to test CCTV systems and their required performance. 4. What adjustments you can make and how to make them. 5. How to recognise when CCTV systems are not working at their optimum performance, and likely causes of unacceptable performance. 6. What information and details of unacceptable system performance you should record so that remedial action can be taken. Arrange for unacceptable performance to be rectified 7. The limits of your responsibility and authority to maintain the performance of CCTV systems, including taking action to rectify unacceptable performance. 8. Terminology used with CCTV systems and equipment, particularly when describing performance, tests and faults. 9. To whom and how to report unacceptable performance, and what information will help them.

EVIDENCE GUIDE (1) Critical Aspects of Evidence You must prove that you confirm operational performance of CCTV systems and arrange for unacceptable performance to be rectified to the National Standard of competence. To do this, you must provide evidence to convince your assessor that you consistently meet all the performance criteria. You must produce performance evidence for both of the following items of range. A.
Test that you would carry out to confirm: (i) (ii)
basic operation (functional) system performance (operational)
You must produce performance evidence for all of the following items of range. B.
Adjustments to systems and equipment: (i) (ii) (iii) (iv) (v)
image quality coverage of cameras camera movement monitor (screen) image quality recording quality
You must produce performance evidence for at least four of the following items of range. C.
Equipment or components of CCTV systems: (Elements 1 and 2) (i) (ii) (iii) (iv) (v)
cameras monitors (screens) systems controls lights recorders
You must produce performance evidence for all of the following items of range. D.
Unacceptable performance: (Elements 1 and 2) (i) (ii) (iii) (iv)
camera image quality camera control monitor image recording quality

U26902
Maintain the operational performance of CCTV systems
You must produce performance evidence for at least two of the following items of range. E.
Relevant person to whom to report unacceptable system performance: (i) (ii) (iii)
internal colleague manufacturer’s or supplier’s representative specialist
The remaining categories can be assessed by other means. Your assessor may ask questions to supplement performance evidence, or to enable you to demonstrate knowledge and understanding for the remainder of the range statement not covered by performance evidence. (2) Methods of Assessment Here are some examples to give you some ideas about the sort of evidence you might be able to find in your daily work: (i) (ii) (iii) (iv) (v) (vi) (vii) (viii)
Control log Occurrence book Incident reports CCTV records Fault reports Engineers report Memos Fax
Observation of you by your assessor. Answers to questions given to you by your assessor. (3) Context of Assessment Your evidence must be the result of real work activities undertaken by yourself. Evidence from simulated activities is not permitted for these elements.
