A direct current (DC) electrical source providing 12 volts, it serves as the energy input for closed-circuit television (CCTV) devices. This component converts standard alternating current (AC) from a wall outlet into the stable DC voltage required for reliable operation of surveillance equipment. For instance, a typical surveillance setup might use this type of power source to ensure continuous functionality of its cameras.
The reliable functioning of security systems hinges on a consistent and appropriate electrical input. Utilizing this type of power source ensures the cameras operate within their specified voltage range, preventing damage and maintaining optimal performance. Historically, inconsistent power delivery was a significant problem for surveillance technology; standardized DC solutions improved stability and reduced equipment failures. These solutions are critical in safeguarding homes, businesses, and public spaces.
