Surveillance on Farms and Ranches: Expert Solutions

Highlight

✔ Farms and ranches consist of vast areas, spanning from hundreds to thousands of acres, making the installation of surveillance cameras challenging.

✔ To overcome these challenges, long-range PoE switches can be utilized to install cameras at specific locations to monitor different spots across the property.

✔ Other measures can also be taken to mitigate the effects of lightning/power surges and camera compatibility issues.

Background

In recent years, the demand for surveillance systems on farms and ranches has increased significantly. These systems help monitor the daily activities and ensure the safety and security of livestock, crops, equipment and personnel. However, these facilities often face unique security challenges due to their vast landscapes, remote locations, and multiple entry points.

Challenges

Farms and ranches often have buildings, wide open spaces, and different points of interest at varying distances from each other, which requires surveillance cameras to be placed at different distances ranging from 100 meters to 500 meters. This poses a challenge in maintaining sufficient power and network connectivity for the cameras.

What’s more, farms and ranches are susceptible to unpredictable weather conditions, including lightning storms, which increase the risk of power surges and system downtime, leading to significant financial losses and even fire hazards. Therefore, protecting cameras from such environmental hazards is crucial for maintaining reliable and continuous surveillance.

The last one is the compatibility issue with passive PoE. Passive PoE cameras are a popular choice in many farm and ranch surveillance setups due to their simplicity and cost-effectiveness. Passive PoE is a technology that delivers power and data over Ethernet cables using different pairs (4-5, 7-8). This presents compatibility issues when integrating with traditional PoE devices.

Solutions

To overcome these challenges, the following solutions can be implemented:

1. Extend PoE+ Signals with Long-Range PoE Switches

Deploying long-range PoE switches can extend the reach of both power and data signals over considerable distances, ensuring proper connectivity for cameras situated at various locations. These switches are designed with a dip switch that can be enabled to extend PoE up to 250 meters at a transmission speed of 10Mbps. Moreover, it can even reach up to 500 meters at 100Mbps when used in conjunction with a PoE extender (5540-75). This flexibility ensures that cameras can be installed at different distances without compromising network connectivity.

Moreover, our series of long-range PoE+ switches also support 4-pair PoE technology, which allows farm owners to install high-power security cameras (30W max.) with pan-tilt-zoom (PTZ) functionalities at a vast distance of up to 400~500 meters when used with a PoE extender. Besides, if you already have a Cisco network switch in the warehouse or barn, you can also connect it to the long-range PoE ports on the new switch, effectively extending the distance beyond the standard 100-meter limitation.

2.Install PoE Surge Protectors in Outdoor Applications

To safeguard surveillance equipment from lightning strikes and power surges, it is crucial to integrate PoE surge protectors into the network infrastructure. These surge protectors act as a barrier, diverting excess energy away from the cameras and other network equipment. By effectively grounding the system and implementing surge protection measures, the risk of damage due to lightning strikes and power surges can be minimized.

The PoE surge protectors are typically installed between the power source, such as a PoE switch, and the connected devices. They actively monitor the power supply and safely redirect excessive voltage by creating a low-resistance path for the surge to flow away from the IP cameras. By installing surge protectors on both sides of a PoE network, the likelihood of camera malfunctions or downtime due to power-related issues can be significantly reduced.

Designed to withstand even the harshest weather conditions, this outdoor PoE surge protector (IP68-rated) operates reliably in a temperature range from -40°C to 85°C. With a high surge protection rating of 16kV and a fast response time of 5ns, it can effectively protect your value network equipment against power surges and transient voltages.

3.Incorporate Passive PoE Converters for Legacy Cameras

To address compatibility issues with passive PoE cameras, the integration of 24V passive PoE converters into the system is essential. While long-range PoE switches are optimized for 4-pair PoE, passive PoE cameras typically operate on a 2-pair system. Therefore, utilizing passive PoE converters allows seamless integration and support for the cameras’ power requirements. 

The 24V passive PoE converters are specifically designed to convert standard PoE to passive PoE. They work by automatically adjusting voltage levels and adapting the power delivery to meet the requirements of the connected device. The inclusion of 24V passive PoE converters allows farms and ranches to leverage existing camera infrastructure without the need for expensive replacements.
