How to Select a PoE CCTV Camera

A PoE security camera sends both power and data over one copper Ethernet cable instead of using separate power wires or outlets. This makes installation easier and more efficient.

It also allows organizations to avoid scheduling an electrician to install additional outlets, and they can deploy security cameras as they need them. This gives businesses scalability for future growth.

Power over Ethernet

Power over Ethernet, or PoE, allows you to transmit both data and power over a single cable. This simplifies installation and reduces infrastructure and labor costs. It is important to select a camera that uses PoE to minimize the number of cables required.

In addition, PoE cameras can be integrated with other network devices and systems, including video management software (VMS) and access control systems. This increases their utility and enhances the security of your premises.

To get started, you’ll need a network switch or injector that supports PoE and a compatible network camera. The cost of these devices can vary, but a basic PoE switch will start at around $50 and more advanced models can range in price up to hundreds of dollars.

Since PoE cameras receive power over the ethernet cable, they can be installed in a variety of locations without the need to be near electrical outlets. This freedom provides greater flexibility and versatility in camera placement and makes relocating or repositioning cameras simple. Additionally, PoE-enabled devices can typically draw less power than other devices, allowing you to save energy. A negotiation process between the power supply and devices ensures that only those devices needing power are provided with it, reducing waste and potentially damaging over-voltage conditions.

Field of View

The field of view (FOV) in a PoE security camera defines how wide an area a device can see. This is a crucial factor to consider when selecting and placing your surveillance devices. A wider FOV can help to minimize blind spots and provide comprehensive coverage.

There are many factors that can affect a camera’s FOV, including its lens size and the distance between the subject and the lens. The image sensor also plays a role in determining the camera’s FOV. A higher resolution sensor will allow for a larger FOV than poe cctv camera a lower resolution sensor. Additionally, the type of zoom support can impact the camera’s FOV. Some cameras feature a fixed zoom while others offer variable or optical zoom.

Choosing the right Dual Lens Camera lens for your surveillance needs can significantly improve your video quality. A telephoto lens offers better close-ups while wide-angle lenses are ideal for capturing large areas.

Each room, home and yard is different, which makes finding the perfect angle for your surveillance a bit of a personal quest. However, some techniques can make this process easier. For example, by mapping out the location of your cameras and mounting them at the optimal height, you can maximize their field of view. In addition, by strategically planning the overlap of multiple devices, you can ensure continuous coverage and eliminate blind spots.

Night Vision

A camera’s night vision can be a critical aspect for surveillance applications in dark environments. The quality of a camera’s night vision depends on several factors, including the camera’s optical zoom capabilities and the type of image sensor used. Some cameras have fixed zoom lenses, while others have variable zoom features. In addition, the type of IR LEDs can affect the camera’s night vision range.

PoE IP cameras combine power and network connectivity in a single cable, making them an excellent choice for commercial security applications. They are easy to install and require less maintenance than wired cameras. This guide will walk you through the basics of PoE cameras and provide information about how to choose the best model for your needs.

To connect a PoE camera to an NVR, first ensure that the NVR is connected to a router. Then, connect the PoE Switch to the router and the cameras to the switches using Ethernet cables. It’s important to follow the daisy chaining order of Router > PoE Switch > NVR.

There are a number of considerations when choosing a PoE surveillance system, including installation costs and the cost of video management software and analytics. Depending on your location, you may also need to factor in permits and compliance costs. Labor costs are another major expense to consider when estimating the overall project budget.


Unlike analog cameras, which require dedicated power cables and separate monitors to view footage, PoE security cameras combine power and data into one cable, making them easy to install. They also offer a number of additional benefits, such as remote access and flexibility in installation.

When choosing a security camera, be sure to look for one with an optical zoom feature, which allows the camera to enlarge image details without losing clarity. This is the best way to capture license plate numbers or faces from a distance. To avoid pixelation and blurring, choose a camera with at least a 4x optical zoom.

Digital zoom is an alternative to optical zoom, but it’s not as effective. It works by enlarging the picture, but it can be difficult to use when a subject is moving or if there are a lot of objects in the frame. Digital zoom is also not useful when viewing recorded video, because it cannot be used to enlarge objects that have already been captured by the camera.

The Zxtech 4K 8 Megapixel Ultra HD PoE IP CCTV Camera comes with a Sony Starvis chipset and processor and a high-quality wide-angle lens. It is weather and vandal-resistant, making it ideal for indoor or outdoor use. It offers remote viewing capabilities via the app on your mobile phone, tablet or computer.
