Why Do Surveillance and Remote Security Systems Need Long Range PoE?


PoE saves the extra external power needed to power some devices on the network. In addition, there is no need to install fiber optic cables, and no need to focus on choosing fiber optic cables for PoE, the existing Cat5 Ethernet cables can complete the task of data transmission and powering devices, which is done through PoE switches.

Now there are many devices on the network, such as IP cameras, IP phones, etc., which can be powered by PoE, so these are PoE devices. These devices are widely used in security and surveillance because of the advantages they provide. This is mainly because long-distance PoE can expand transmission capacity over geographic distances while simultaneously powering devices on the network. This article discusses what long-range PoE is, and their uses and advantages in remote security systems.

PoE Switches for Security Systems

PoE saves the extra external power needed to power some devices on the network. In addition, there is no need to install fiber optic cables, and no need to focus on choosing fiber optic cables for PoE, the existing Cat5 Ethernet cables can complete the task of data transmission and powering devices, which is done through PoE switches.

It's a regular switch with three prongs that can be hooked up to a power strip for power. It converts this energy into low-voltage energy and provides it to connected devices on the network. Basically, an ethernet cable is made up of about 8 cables, 4 of which are used for data transmission and 4 for power. This is especially useful for remote security systems, where cameras may be located in remote and remote locations where power supply may not be possible. Here are some advantages of using PoE switches for remote security systems:

  • PoE switches simplify the task of finding locations where cameras may need to be installed.
  • They save time, cost and reduce wiring complexity.
  • These switches are compact and expandable and can be easily transported from one location to another if required.
  • These switches have varying numbers of ports from 4 to 48 and come in both managed and unmanaged types. While unmanaged switches are pretty basic, they can still effectively power your network.
  • Smart or managed switches are better in terms of control and functionality.
  • With minimal external interference, PoE switches provide a good level of security for the network.

Elements of Monitoring PoE

When it comes to monitoring PoE (Power over Ethernet) systems, several basic elements are involved to ensure an effective and reliable monitoring function. Here are the key components and their roles in a monitoring PoE setup:

Surveillance cameras: PoE-enabled surveillance cameras are a major part of the system. The cameras receive power and data over a single Ethernet cable, simplifying installation and allowing flexible camera placement.

PoE Network Switch: The PoE switch acts as a central hub for monitoring the PoE system. They provide power and network connectivity to PoE cameras for seamless communication and control. PoE switches usually have dedicated PoE ports to provide power efficiently.

Ethernet Cable: A high quality Ethernet cable such as Cat5e or Cat6 is used to connect the PoE camera to the PoE switch. These cables carry power and data, ensuring reliable and efficient communication between cameras and network infrastructure.

Power Sourcing Equipment (PSE): PSE devices such as PoE switches or injectors provide power to surveillance cameras. These devices ensure proper power distribution and provide the necessary voltage and current to support camera operation.

Network Video Recorder (NVR): NVR is a key element in a surveillance PoE system. It acts as a centralized storage and management unit for video clips captured by PoE cameras. NVR allows recording, playback and remote access to surveillance footage.

Monitoring and management software: Surveillance PoE systems rely on specialized software to monitor and manage cameras and recorded footage. The software supports live video streaming, camera configuration, motion detection, event recording and remote access to the surveillance network.

Power Management and Redundancy: Effective power management is critical to monitoring PoE systems. Implementing features such as power scheduling, power monitoring, and redundant power supplies ensures continuous operation and minimizes the risk of power failures that could disrupt monitoring activities.

Integration with security systems: Monitoring PoE systems can be integrated with other security components, such as access control systems, alarms, or video analytics software. This integration enhances overall security effectiveness and supports a comprehensive monitoring solution.

Benefits of Long-Range PoE for Security and Surveillance

The IEEE802.3 standard for PoE devices helps manufacturers launch devices that comply with IEEE specifications to meet the growing demand. This demand is mainly due to the advantages of PoE systems, especially in the field of security. Initially, although PoE has advantages such as simultaneous power supply and data transmission, it has limitations in terms of distance. However, long-range PoE largely helps solve this problem. Depending on the type of cable, this technology can extend the transmission distance. Long distance PoE is basically a managed switch that saves on fiber optic cable costs and is easy to install.

Here are some of the reasons why PoE systems find application in the surveillance world.

  •  A major problem in this field is remote access and installation, of devices in remote locations without grid access. This is where PoE systems come in handy.
  •  In addition to basic functions, PoE systems also have battery backup capabilities necessary for remote locations.
  •  It supports low and high data rates up to 10Gbps.
  •  PoE makes the monitoring system cost-effective as there is no need for signal splitters, multiplexers, etc.
  •  Users of the surveillance system can remotely control CCTV cameras located in hard-to-reach locations.
  • They can remotely reset cameras or calibrate devices connected on the network via PoE.

If you plan to enhance your CCTV cameras with PoE, make sure to source the equipment from reliable manufacturers and suppliers.
