Using an Ethernet connection, security cameras may be powered via Power over Ethernet (PoE). The cable performs dual functions as it offers network connectivity in addition to electricity. The definition of PoE cameras, their advantages, and the characteristics to consider when assessing PoE security camera systems are all covered in this tutorial.
Given how commonplace video technology is currently, it should come as no surprise that business security camera systems are becoming more popular. Worksite cameras, which were initially primarily utilized for security, may now assist with a number of operational tasks, such as process workflows and safety, in addition to security monitoring.
The days of distorted, blurry video recordings are long gone. Power over Ethernet (PoE) camera systems are a strong, dependable, and affordable option for businesses and organizations trying to optimize their video security setups.
What PoE security camera systems are and how they vary from other systems will be covered in this article. We’ll also go over the main advantages of different solutions and demonstrate the characteristics to look for when assessing systems.
What are security cameras that use PoE?
Let’s examine the definition and operation of a PoE security camera.
Power over Ethernet is referred to as PoE. PoE is a technology that uses copper Ethernet cables to transmit data and electricity, so each camera only needs one connection. PoE can assist simplify installation and enable more flexible camera placement if you have hundreds or thousands of cameras since it eliminates the need for separate power connections and outlets.
PoE technology powers internet protocol (IP) cameras, which are security cameras. Similar to a webcam, these digital video cameras transmit and receive data via the internet. However, IP cameras have independent IP addresses, in contrast to simple webcams. Like PCs and printers, you link them to networks.
PoE cameras are not all IP cameras. Certain IP cameras must be connected to wall outlets. PoE only specifies the power supply for certain IP cameras.
How does PoE differ from other kinds of security camera systems?
The methods in which various kinds of video surveillance systems operate vary. The devices utilized and the kind of cabling needed determine how different systems differ from one another. An outline of the many types of security camera systems is provided below:
In the past, analog camera systems were the norm. Consider how CCTV cameras became well-known through criminal dramas. A digital video recorder (DVR) that processes images is connected to these security cameras. They require two cables: one for the DVR, which is often a coaxial cable, and another for the power source. Even while analog cameras are still in use today, most consumers choose IP cameras because of their improved video quality and modern technologies.
WiFi camera systems make use of wireless cameras that send or stream video to a server located in the cloud. WiFi systems are wireless, as their name suggests, and for maximum flexibility, they frequently include cameras that run on solar or battery power. A lot of home security systems, including video doorbell cameras, use WiFi to function.
IP camera systems record and preserve video by using wired internet protocol (IP) cameras to transfer video feeds to a network video recorder (NVR). Many corporate and industrial operations employ IP security camera systems because they are thought to be more dependable and powerful than WiFi systems.
The sole distinction between PoE and IP camera systems is that PoE camera systems employ PoE cameras exclusively. PoE cameras are a kind of IP camera that can get electricity and network access from a single Ethernet connection. This makes installation easier and more flexible because only one wire is required for each camera.
What characteristics of a PoE security camera system should you look for?
With so many features and options available, choosing a PoE security camera system that best suits your needs might be difficult.
Resolution of the Video
The first security cameras that employ the megapixel (MP) grade often found on digital photography cameras were IP cameras. The video resolution that a camera can record is indicated by its MP rating. This resolution determines how much detail the camera can capture and how well digital zoom works before pictures start to get distorted and blurry. The three most widely used resolutions are 8MP 4K, 4MP 2K, and 2MP 1080P.
Explaining how much face information each resolution can capture is helpful because these resolutions and MP ratings may not signify much to many people. To satisfy varied needs, we advise adding several resolutions to your system. If you need to identify faces up to 50 or 70 feet away, choose 8MP 4K cameras. In situations when precise facial recognition is not as important, lesser resolutions such as 2MP 1080P or 4MP 2K should be adequate. Our Security Camera Buying Guide contains further information about the variations in camera functions and resolutions.
The capacity to see at night
IR night vision or Starlight technologies are commonly used by night vision cameras to capture black-and-white footage. Purchasing a camera with 100 feet of infrared night vision just indicates that the camera can project infrared light that far; it does not guarantee that you will be able to see every detail at that distance.
With adequate ambient illumination, the camera may remain in color mode thanks to starlight technology, also referred to as “color night vision,” which increases the light sensitivity of the image sensor. When there is not enough light to remain in color mode, starlight cameras—which often feature infrared LEDs—go into black-and-white mode.
Consider a motorized zoom or PTZ camera that has more than 200 feet of night vision if you need to take pictures of faces or small details that are more than 60 feet distant from the camera.
Viewing from a distance
Remote viewing is a great way to keep an eye on your property, whether you’re a manager, homeowner, or company owner. A PoE camera system with remote viewing applications must take certain factors into account, even if remote access is typically common with contemporary security systems. These include the ability to see remotely using PC or Mac applications, push alerts, simple setup via QR code without complicated port forwarding, and possible monthly costs. Notably, these viewing capabilities are free of charge for any CCTV Camera World cameras and systems!
