How to Understand PoE and PoE+ Switches [2018-05-04]
By: Angelina Li Power-over-Ethernet (PoE) is the technology that allows network switches to transmit power and data through an Ethernet cable at the same time. PoE switch streamlines both of the processes of powering and providing data to the device, which makes it a straightforward and reliable device for home network and small enterprise application. This article describes two types of PoE (PoE and PoE+) that are commonly used and provides information on what types of PoE can be used according to different applications. PoE Versus non-PoE Technology Power...
Considerations to Choose a 24-port PoE Switch [2018-05-04]
By: Chloe Purpose built for converged networks where video, voice and data are carried over a single network platform, PoE switches with 8 port, 24 port and 48 port represents an ideal solutions for different size networks like home or SMBs (small and mid-size business networks). 24-port gigabit PoE switch is a relatively commonly used network switch, which in turn cause hot discussions in forums and communities. Then what to consider when choosing a 24-port PoE switch? As we know, the basic types of a network switch are managed switch, smart managed switch and unma...
POE TYPES: WHAT THEY MEAN AND HOW THEY’RE USED [2018-05-02]
By: Ron Tellas Serving two purposes with one cable: That’s what Power over Ethernet (PoE) can do. This technology allows network cables to not only carry data, but also deliver electrical power to networked, IP-enabled devices. Before PoE, two connections (an electrical connection and a network/data connection) would have been required in order to join devices like IP cameras to the network. PoE combines these two into a single network cable. PoE can enable fast installation and deployment, lower operating costs and maximum reliability for toda...
POWER OVER ETHERNET SWITCH: PASSIVE POE VS ACTIVE POE [2018-05-02]
By: Angelina Twain Power over Ethernet (PoE) is a technology for wired LANs. This allows a single cable, usually Ethernet cable, to provide both data connection and electric power to devices such as IP cameras, NVR recorders, wireless access points, etc. A PoE switch, compared with other Gigabit network switches, has power over Ethernet injection built in. This feature allows end-user to power PoE capable devices without the need for a separate power supply or the need for an electrical outlet near the powered device. What is PoE Switch? As mentioned...
What Is The Main Advantage of Power Over Ethernet (PoE)? [2018-04-28]
By Rita Mailheau, Source: versatek.com The main advantage of Power over Ethernet (PoE) is delivery of data AND power over one Cat5e/Cat6 Ethernet cable. PoE ends the need for AC/DC power supplies and outlets. A remote installation costs less than fiber as no electrician is required. Ethernet cable costs less and is often already installed buildings. This article will explain the many advantages PoE has to offer. What began as an effort to squeeze more speed and power out of existing cabling has become a force within the IT network...
What is the difference between a PoE injector and a PoE splitter? [2018-04-28]
By Rita Mailheau, Source: versatek.com The difference between an injector and a splitter is that a PoE injector sends power to PoE equipment that receives data through existing non-POE switches. A splitter also supplies power, but it does so by splitting the power from the data and feeding it to a separate input that a non-PoE compliant device can use. What is Ethernet technology? Power over Ethernet (POE) technology sends 10/100/1000 Mbps of data and 15W, 30W, 60W, and up to 90W of power budget to devices over Cat5e an...
CCTV with Audio: 3 Things to Know [2018-04-27]

If you're in the market for a camera with built-in audio, here are a couple of things to keep in mind. CHECK CCTV DVR AUDIO INPUTS Before thinking about the mics, think about the HD DVR. The microphones (even ones built-in to cameras) need an input on the DVR. Buying 8 cameras with 8 mics for an 8 channel DVR that only accepts 4 audio inputs is a frustrating experience. Make...
HOW TO SET UP A MICROPHONE FOR CCTV SYSTEMS [2018-04-27]
Source: Audio Forensic Expert CCTV systems have become a major contributor of evidence to court cases. While the video from these systems is often very important, the audio can often play just as much of a role in the investigation. Many times, the audio is more valuable than the video because of what was said during the event. While enhancing the audio is possible, setting the microphone on the system correctly can be extremely beneficial when an incident does occur. Getting a good, clean signal from a microphone relies on two key principles: microphone gain and micro...
