The installation of a video surveillance system requires careful planning beforehand. To ensure everything is carried out safely, it is essential to consider all technical aspects that may influence the project’s functionality.
For enhanced security, it is crucial that the entire process is handled by specialized technicians in this field and that the equipment is prepared for the type of environment where the installation will take place.
Electrical Energy
In other articles on our blog, we’ve discussed key aspects such as selecting the right equipment, lighting, and the process of calculating data storage and transmission. However, ensuring proper power supply to the equipment is one of the most critical factors for securing your perimeter. In this article, we’ll explore some key concepts to address this.
Transient Surge
A transient surge is an electronic concept referring to a brief spike in electrical voltage that occurs over a very short period. This rapid fluctuation in current can damage equipment and systems.
One of the most common causes of this phenomenon is lightning strikes on electronic systems. However, lightning strikes are external events and occur less frequently than internal electrical network issues that can cause voltage transients.
To prevent damage to your equipment and ensure the security of your project, it is necessary to use devices designed to withstand surges and transients. Typically, external Axis cameras include this resistance.
Additionally, using shielded twisted-pair (STP) cables in conjunction with surge-resistant equipment and Power Sourcing Equipment (PSE) provides greater protection against electrical surges. Below, you can see the combination of these devices in a diagram designed by Axis:

Always use an STP network cable between the camera and the PSE, and ensure the PSE is properly grounded.
Using Power over Ethernet (PoE) for power supply is advantageous for mitigating internal electrical issues, as this technology allows for the use of a single cable for both energy transmission and data, simplifying installation and preventing power cables from coming into contact with other components.
