Some of the common low voltage security work includes:

• Access Control Systems: These systems use various technologies, such as biometric scanners and key card readers, to control access to a building or specific areas within it. Low voltage security workers may be involved in designing, installing, and maintaining these systems.

• Burglar Alarms: These systems are designed to detect unauthorized entry into a building and sound an alarm to alert security personnel or law enforcement. Low voltage security workers may be involved in installing, testing, and maintaining these systems.

• Fire Alarms: These systems detect smoke or fire and alert building occupants and the fire department. Low voltage security workers may be involved in designing, installing, and maintaining these systems.

• Intercom Systems: These systems allow communication between different areas within a building. Low voltage security workers may be involved in installing, testing, and maintaining these systems.

• CCTV Systems: These systems use cameras and recording equipment to monitor and record activity in a given area. Low voltage security workers may be involved in designing, installing, and maintaining these systems.

In addition to these systems, low voltage security work may also involve other tasks such as troubleshooting, repairing, and upgrading existing systems, as well as ensuring compliance with local codes and regulations.
