What is an IP Camera: Understanding Its Types, Working, and Pros/Cons
Do you know what IP cameras are? IP Cameras, also known as Internet Protocol or Network Cameras, are an integral partof security solutions for both residential and commercial areas. These cameras offer advanced features and functionalities, making them a go-to for many.
In this guide, we aim to understand what IP cameras are. Look into their types and how they work, as well as the pros and cons they have to offer.
What is an IP Camera?
Let’s begin by understanding what an IP Camera is. Internet Protocol (IP) cameras are digital video cameras that transmit and receive footage over the Internet or a local area network (LAN). They are nothing like traditional analog cameras, which need a digital video recorder (DVR) or a monitor. IP cameras work independently and are connected to the network wirelessly or through a PoE (power over Ethernet) cable. Since they are connected to the Internet or a local network, they allow you to access the footage from anywhere.
IP Camera: How Does it Work?
Now that we know the answer to the question of what an IP Camera is let's figure outhow it works. These cameras work by converting analog video signals into digital video signals, which are then compressed and transmitted over an IP network. Confused? Let’s break this down into simpler steps and understand how an IP camera works:
Step 1: Capturing the Image
IP Cameras start by capturing a video using an image sensor. The image sensors usually used in these cameras are either CMOS or CCD sensors. Now, what do these sensors do? They convert light into electrical signals, meaning the visual information is converted into electronic information. The captured video is then processed by the internal components of the camera to produce a digital image.
Step 2: Compression
Once the videos are converted into a digital format, they are compressed. Compression is necessary to reduce the size of the video files. Reduction in the size of the video not only makes it easier to be transmitted over the network but also minimizes the storage requirements.
IP cameras use various compression algorithms or codecs, including H.264 or H.265, to compress the video without compromising the quality of the image. These codecs analyze the video frames and remove unwanted information while keeping essential information, significantly reducing the file size.
Step 3: Transmission
Now that the video is compressed, it is transmitted over a network. This network can either be wired or wireless, and the nature of the network depends on the camera's connectivity options. Wired cameras are connected via an ethernet cable or network switch, providing stable and reliable data transmission options. On the other hand, wireless cameras are connected via a Wi-Fi or cellular network, so you can place the cameras anywhere you want. No matter what type of connection is used, the video footage is either sent to a central recording device or network video recorder (NVR).
Step 4: Storage and Playback
Once the video footage reaches the network video recorder, it is stored on the device’s hard drive or cloud storage. An NVR is like a single storage device that stores video footage from various IP Cameras. Moreover, it lets users access footage from anywhere and at any time, allowing them to view recorded footage, live streams, or change camera settings—all you need is an internet connection.
Furthermore, some IP cameras also come with local storage devices, such as a microSD card, so your camera can store the footage locally if there is a connectivity issue.
The HIDIX - 1080p Wireless Magnetic Mini Camera from Zetronix lets you save 264 hours of footage on 64 GB and also accepts a microSD card to store videos locally in case of a connectivity issue.
Types of IP Cameras:
There are different types of IP cameras available in the market, each designed to meet your specific needs. Here is a list of cameras available in the market that you can use for your surveillance needs.
Fixed IP Cameras:
As suggested by the name, Fixed IP Cameras have a stationary lens that offers a fixed field of view. Such cameras are ideal for monitoring fixed areas, such as parking lots, hallways, or entrances.
PTZ IP Cameras:
PTZ (pan-tilt-zoom) IP Cameras give the user remote control over the camera's movement so that the user can pan, tilt, and zoom to capture the footage from various angles. These cameras are used in large areas such as stadiums and industrial facilities for comprehensive coverage.
