What can I do for you?
An IP camera (Internet Protocol Camera) is a security camera that receives video data and sends video footage over an IP network, it is also known as a webcam or IP security camera, and is often used as a remote monitoring and management tool in many industries and environments to protect property or monitor home, business, or public safety.
Connected to other devices such as webcams and monitors via the network, IP Cameras allow you to monitor a specific area from any remote location, bringing a lot of convenience to our daily lives.
IP cameras work in the same way as digital cameras and can capture high-quality images. What sets them apart is the IP camera's ability to compress these files and automatically transmit them over the network to a Network Video Recorder (NVR).
Typically, IP cameras are connected to the network via an Ethernet cable with a broadband modem or router, or wirelessly through a Wi-Fi router.
In a building that is already equipped with a network, all you have to do is connect IP surveillance cameras and other devices to your network system, just as you would do when you connect your laptop or phone to your network system. Wi-Fi.
Once everything is connected, the camera can start working, capturing video footage and sending it to a network recorder.
There are various video surveillance solutions in which many different types of security cameras are employed. Among these security cameras, the most commonly used are three:
When looking for a security camera, you should not only decide on its type, but also be aware that the specifications can make a huge difference, there are four of the most basic ones.
The resolution of an IP camera is the total number of pixels that make up an image, usually measured in the width and height of the image. The most common resolutions for security cameras are 720p, 1080p, 5MP, 4K, and 8MP. In general, higher resolution means more pixels per inch (PPI), resulting in high-quality, crisp images.
The lens of the IP camera allows you to frame the area you want to position. Different lens systems have different fields of view, which determines the width of the area you can see. A wider field of view will allow the camera to discover larger areas. Usually, for large parking lots and small rooms, you will need lenses with different perspectives.
The focal length of the lens (in "mm") determines the angle of view and the distance at which the camera can see. There are two types of lenses, fixed lenses and zoom lenses. The most common fixed focal length is 3.6mm, which results in a 90° viewing angle and a distance of 20 feet. There is also an 8mm lens with a viewing angle of 40° and a recognition distance of 40 feet.
For zoom lenses, the most common is a 2.8-12mm lens. At 2.8 mm, you can get a viewing angle of about 100° with only about 10 feet of recognition distance. At 12 mm, you will achieve a viewing angle and recognition of about 50° at about 30 feet. The wider the focal length, the farther the focusing distance and the narrower the field of view.
Low light sensitivity, usually measured in lux (lx), refers to the camera's ability to deliver high-quality images even in low light conditions by rendering detail and reducing noise in the output image. There are few factors that affect the camera's low-light performance, including pixel size, signal-to-noise ratio, lens aperture, and so on. The lower lux is able to render high-quality images in darker areas. For example, a 100-1,000lx camera is used to record in workspace light, while a 0.0001lx camera is typically used on a moonless or cloudy night.
Application of IP camera
IP cameras are always the first choice for those who are looking for tools to be close to their family, monitor home security, or protect family property. Many homeowners equip their families with video surveillance systems to make them and their families feel safer.
IP cameras installed in home security systems have been used for a variety of purposes. For example, they can be installed near the front door to capture the image of every person who walks in or sneaks around, or in the backyard to capture happy moments for the family, or installed in the room to ensure that their children are well taken care of, and so on.
Commercial security cameras are commonly used in commercial buildings, supermarkets, shops, restaurants, etc. For business owners, security cameras not only protect their property, ensure normal operations, prevent crime through Real-time monitoring, but also keep them connected with daily operations and employee safety.
Outdoor perimeter security can also monitor the surrounding environment with video surveillance solutions. Commercial IP video surveillance systems offer greater reliability and security than traditional systems with built-in encryption, data compression, network connectivity, and cybersecurity measures.
Surveillance cameras play an important role in managing public rules, protecting public safety, and property. It is not difficult to find that there are a large number of surveillance cameras along traffic roads, parking lots, and around governments or hospitals. In addition, security cameras have been deployed in many public areas, including schools, parks, neighborhoods, neighborhoods, etc.
IP cameras have become an integral part of home, business, or public surveillance systems. With the right video management software, video recorded by IP cameras can be viewed over the network from anywhere in the world, whether using a laptop or mobile phone. In many cases, webcams can also be controlled remotely, adding a lot of convenience to our lives.
There are many types of security cameras designed for specific applications, which is why there are several factors to consider when buying an IP camera for your security system. Before taking the next step, it's a good idea to figure out your budget and requirements.
