Guide to buying ip camera


What is IP technology?

IP technology is a communication protocol used to transmit digital data packets across a network. IP cameras were first introduced to the market in the 1990s.

How does IP camera work?

A network camera (IP Camera) connects directly to the computer network and transmits images through the computer network. In order for an IP Camera to start, it will require a high-speed internet connection, intranet, or LAN network. The way the network camera connects to the network is the likes of other network equipment.

IP Cameras are digital at both heads (origin and destination). The advantage of this feature is that the video signal remains digital throughout the process of transmitting from camera to network, which maintains the original quality of the signal. Another advantage of ip cameras is that they allow remote monitoring over the Internet/network connection for the user without the need for a video recording device.

Important tips before buying a network camera (IP Camera)

Before you buy a network camera, you need to know your security needs well. The following questions will help you:

1-What is the shape of your camera better? 2-Your goal is to monitor the interiors or exterior? 3-How carefully do you need imaging? 4-How many network cameras do you need? What do you decide to shoot in low light? 5-Do you have enough bandwidth? Is your IP camera compatible with other IP equipment?


Resolution or resolution

The resolution of IP cameras is measured by pixel count. The image that is more quality is composed of more pixels and has more data than a less detailed image. Network camera resolution means the number of horizontal pixels in the number of vertical pixels, for example: 1280x1024 resolution.

The resolution of the camera and lens determines what you will see. The camera's resolution determines the accuracy and detail in the image. However, the lens determines the distance of the image from the camera and your range of vision (FOV).

Choosing a lens

In addition to determining resolution, the camera lens also determines the range of vision. A lens with a higher focal length offers greater magnification. However, a lens with a lower focal length offers less magnification, but more visibility.

If you choose a high-resolution network camera, it should also be the lens you choose for a high-resolution megapixel lens that can provide the resolution needed to capture high-quality images and precise details. If your camera's image sensor has a high resolution but the lens resolution is not the same, the image of the camera will not be high quality and accurate.

Do you have enough bandwidth?

IP Cameras require network bandwidth to transmit and store images and information. The more cameras connected to the network, the more bandwidth will be needed. High-resolution cameras also require more bandwidth. Ip Cameras reduce the size of video files by using image compression capabilities to optimize network bandwidth and storage capacity.

How many cameras do you need?

Specify how many IP cameras you will need according to your security needs. Do you buy cameras for a large company with multiple entrance doors? Do you want to supervise a residential area? Do you want to install cameras in different buildings of a university? The wider your area is, the more cameras you'll need.

Network camera device compatibility

Many network camera manufacturers use several software companies to help build their own cameras to ensure that their final product is compatible with other equipment.

Many network cameras comply with ONVIF and PSIA. This means that network cameras, in the face of other network security equipment, are measured to work with this equipment and are ready to be naturalized by standards. Network cameras can communicate with other network equipment (such as an NVR video recording device). These cameras are compatible with the security equipment of many manufacturers.

Indoor or outdoor camera?

If you plan to monitor the outdoor space, you will need an outdoor camera with a pod resistant to a variety of weather conditions. If you want to monitor a place where criminal acts are high, you need to get a camera that is resistant to destructive acts (Vandal Proof). Read its features carefully when buying a camera to be sure of your choice.
