Student Learning Outcomes

  • A successful student will be able to construct a CCTV system in a hands-on lab.
  • A successful student will be able to navigate the NEC and NFPA 72 reference books.

Description

Begins with the introduction to intrusion and access control systems (security). Lessons include intrusion basics, applicable codes, protection strategies, cabling and wiring, sensors and devices access control systems, access components, access credentials and electric locks. Next, students study audio visual systems. Lessons include performance issues due to hum and buzz created by power supply leakage current, ground loops and electromagnetic interference, properties of sound, distributed audio and video, planning and testing of audio visual systems. Students will perform hands-on laboratory exercises by installing an intrusion/access control system and an audio visual presentation system.

Course Objectives

The student will be able to:
A. Identify components of intrusion and access control systems.
B. Install a basic intrusion system with access control.
C. Define a balanced audio signal.
D. Define video aspect ratios.
E. Install projector, projection screen, cabling and interface devices of an audio-visual system.

Course Content

A. Security
1. Intrusion components
2. Access control components
3. Security system installation (lab)
B. Power quality
1. Hum and buzz
2. Electromagnetic interference
C. Audio-visual
1. Audio signals (mic, line, speaker)
2. Balanced/unbalanced
3. Wireless RF frequencies
4. Video aspect ratios
5. Audio-visual installation (lab)

Lab Content

Work individually and in teams with intrusion equipment, including contact switches, motion detectors, card readers, and biometric readers. Students will also work with audio-visual equipment, including high resolution RGB cable, HDMI cable, XLR and RCA connectors, video projectors, and projection screens. Students will construct a small scale intrusion, access control system and a typical audio-visual system, including a projection screen, projector, computer interfaces and the wiring needed for a complete functioning system. Equipment safety and safe handling practices are reviewed and applied.

Representative Text(s) and Other Materials

AVIXA. CTS Certified Technology Specialist Exam Guide, 3rd ed.. 2020.

This is the standard Sound & Communications textbook/workbook used for this course. Although it may not be within 5 years of the required published date, it is the most current book used when teaching this course. We will adopt the next edition of the text, as it is published.

Types and/or Examples of Required Reading, Writing, and Outside of Class Assignments

A. Reading assignments, for example:
1. CTS Exam Guide, Chapter 3, Analog vs. Digital Signals
2. CTS Exam Guide, Chapter 4 (pages 49-51), Sound Capture
B. Writing assignments, for example:
1. Describe the difference in function between wiring a door contact in series as compared to parallel; provide an example of when you would use each wiring method
2. Describe the principles of how a balanced microphone signal operates
C. Other:
1. Online videos: videos (created by the JATC) accessed on Canvas CMS, including lessons on RF, intrusion, access control, and audio-visual systems
