What Are PoE Cameras and PoE Injectors?
Internet protocol (IP) cameras are digital video surveillance systems that connect to networks like computers and printers. They have unique IP addresses and offer a variety of useful features, making them a popular choice for enterprise organizations.
Unlike fixed security cameras, PoE PTZ cameras can pan, tilt and zoom to cover wider areas. You can control these motorized cameras from your computer or mobile device using an app. These models also come with smart human detection and auto-tracking.
Power over Ethernet (PoE)
PoE lets you power network devices over existing network infrastructure without requiring electricians to install additional electrical outlets. This can be particularly helpful when you want to place a network device in an awkward location, such as on the top of a skyscraper or in a basement.
This technology allows you to send data and power over a single Ethernet cable. To use it, simply connect the end of your network cable to your device and plug in a power source—such as a Power over Ethernet injector or switch—to the other end. Then, select the network port on your device that’s labeled as PoE and connect it to the PSE.
Unlike older cameras that required complicated wiring and expensive joystick controllers to operate, PoE-enabled devices like the Reolink TrackMix PoE are easy to set up. All you need is a high-speed Internet connection to view the camera’s live video stream from anywhere, including on your smartphone or tablet.
In addition to making it easier to set up your surveillance system, using a POE PTZ camera can also help you save money on electricity costs. Since PoE transmits low-voltage DC directly to your device, it avoids the energy loss that occurs when AC is converted to DC at the point of load. This can significantly lower your energy costs.
High-Power PoE Injector
PoE injectors are a great way to upgrade existing infrastructure without the expense of purchasing and installing new switches. They allow you to use the existing Cat5e, Cat6 or Cat6a cabling to deliver both power and data. They also protect equipment from power problems, such as short GRND connections and current overloads.
Injectors are simple devices that take the unpowered Gigabit Ethernet signal and “inject” power on top of it for the PoE device. They are ideal for situations where you need only a few ports of PoE or to bolster poe indoor camera a PoE switch that has run out of power budget.
The best PoE injectors offer a high level of reliability and ease of installation. They are compact and integrate power conversion, management and a power/data connection in one unit. They also feature LED poe ptz camera indicators that show real-time power consumption. Fastcabling offers a wide range of advanced PoE injectors to meet your needs.
When selecting a PoE injector, it’s important to consider the maximum transmission distance rating. This number will tell you how long the device will remain powered over your wired network. For example, if you’re installing an IP security camera that requires 10 watts of power, you should choose a device with a high transmission range rating.
PoE Switch
A PoE Switch is a device that passes power along with data over an Ethernet cable. It is used to power a wide range of network devices like security systems, VoIP phones, wireless access points, and more. You can find different types of PoE switches, ranging from low-cost unmanaged units to complex rack-mounted models.
Before the advent of PoE technology, each network device required its own power cord. This resulted in a tangled mess of cables. With PoE, you can run both data and power over a single Cat5 or Cat6 Ethernet cable. This eliminates the need for dedicated power outlets and reduces maintenance costs.
Most newer IP cameras are PoE compatible. This enables them to be deployed quickly and easily, and they can also be repositioned without the need for additional wires. This is a great solution for remote locations that would otherwise be difficult or impossible to connect to AC outlets, such as digital signage on the top of skyscrapers or CCTV camera placements in hard-to-reach places.
You can even use a PoE switch to upgrade existing non-compliant network devices. You need a special splitter to do this, but it can make your device work just as well as an IP camera that’s powered via PoE. You can also use a PoE extender to lengthen your network connection beyond the standard 100-meter limit for twisted pair Ethernet.
Power Supply
While power-over-ethernet has become a reliable and widely used technology, it does require some physical components to work. These physical parts need to be carefully installed and maintained to ensure the highest level of reliability. If they’re not, your PoE camera system can fail and cause problems for your business.
A good way to avoid this is by using a PoE injector, network switch with a high-power PoE port or direct AC/DC power options. Injectors are a great option when you’re installing only a few devices because they can provide higher output power than standard PoE switches. Also, you can use the same type of injector to power legacy devices in your security system and reduce wiring costs.
Another benefit of PoE is that it allows you to power and connect IP cameras to a network without the need for separate cables. The single Ethernet cable conducts both network access and electric power, so you can install cameras farther away from an electrical outlet than if you had to run an extension cord or find a power outlet.
Many of our PoE PTZ cameras have features that allow you to automatically move the camera to preset positions. This feature is known as TOURS or CRUISE, and it makes it easy to monitor your premises. Some of our models even have automatic human detection, which eliminates the need for a video motion detector by detecting only real people and ignoring objects like flags and branches.
