What Are the Main Classifications for Commercial Cameras?
Analog cameras have been around the longest and are commonly found in pre-existing systems. They are inexpensive, but they also do not have a very high image quality. They require coaxial cable, and the wires limit the distance the cable can run without additional equipment. They work by transmitting the image back to a recording device like a digital video recorder or DVR for short.
Analog High Definition or just referred to as HD cameras, is an improvement over traditional analog cameras. They have significantly better image quality, compatible with newer and more advanced DVRs, and have color and night vision capability. As their name implies, you can capture HD quality images (1080p) and see much more detail in your recordings. HD quality images can be beneficial when you need to identify intruders or verify the details of an office disagreement or worker’s comp claim. Another advantage of HD cameras is that you will not incur any additional cabling expenses as they can utilize the same coaxial cable as their analog predecessors.
IP cameras are a substantial upgrade in features and image quality from both forms of analog cameras. The IP stands for “internet protocol” and utilizes an ethernet cable (or wireless network) to transmit the signal back to a network video recorder (NVR). (We will go into more detail about storage later on, so stay tuned.) They are easy to access and view from anywhere, have higher image resolution, and provide data like motion detection, facial recognition, people counting, spatial distance (aka social distancing), and temperature screening solutions.
