![]() ![]() There is also 8mm lens with a 40° view angle and identification distance of 40 feet. The most common fixed focal length is 3.6mm, which leads to a 90° view angle and a distance of 20 feet. There are two types of lens, fixed lens and varifocal lens. The focal length of a lens, which is measured in “mm”, determines the angle of view and how far the camera can see. Typically, for a large parking lot and a small room, you will need lenses with different viewing angles. ![]() A wider field of view will allow the camera to spot a larger area. Different lens systems come with different fields of view, which determines how wide an area you can see. The lens of an IP camera allows you to frame an area that you want to spot. Usually, higher resolutions mean that there are more pixels per inch (PPI), resulting in a high-quality, crisp image. The most common resolutions of security cameras are 720p, 1080p, 5MP, 4K and 8MP. The resolution of IP cameras is the total number of pixels that make up an image, which is usually measured by the width and height of the image. There are four of the most essential specifications. When looking for a security camera, not only should you decide on the type of it, but also you need to notice that the specifications can make a huge difference. ![]() Parking lots, shops, industrial settings, airports.įour Important Specifications of IP Cameras Schools, shops, industrial settings, traffic lights, and high crime areas. Less intrusive than bullet and turret cameras Įasier to vandalize than dome and turret cameras Among those surveillance cameras, there are four most commonly used ones, dome cameras, bullet cameras, and turret cameras. Knowing more about the differences among dome vs bullet vs turret vs fisheye cameras will help you find out the one that fits you most. There are various video surveillance solutions, in which many different types of security cameras are adopted. In a building that has already been equipped with a network, all you have to do is to connect the IP surveillance cameras and other devices into your network system, just the same way that you would do when you connect your laptop or cell phone to your Wi-Fi.Īfter everything is well connected, the cameras can start working, capturing and sending video footage to the network video recorder. Usually, IP cameras are connected to the network via ethernet cable with a broadband modem or router, or wirelessly via a Wi-Fi router. What sets them apart is the capability of IP cameras to compress those files and automatically transmit them to a network video recorder (NVR) via a network. IP cameras work the same way as digital cameras to capture high-quality images. Connected with other devices such as network video recorders and displays via a network, IP cameras allow you to monitor specific areas from any remote location, bringing much convenience to our daily lives. It is also known as network camera or IP security camera, often used as remote monitoring and management tools in many sectors and environments to protect the property or monitor home, business, or public security. An IP camera (Internet Protocol Camera) is a type of security camera that receives video data and sends video footage via an IP network.
