Internet protocol (IP) cameras have brought a new dimension to modern home and business security. They have revolutionized the applications of security cameras everywhere and can be effectively employed as both surveillance and security. Today, I’m going to go over how IP cameras work, how they are differentiated from old school closed circuit television (CCTV) cameras.
Analog vs Digital
CCTV cameras transmit video recordings as voltage, sending an analog signal to a digital video recorder (DVR). The DVR translates what it receives from the camera into a digital video output. This communication goes one way, from the CCTV to the DVR.
IP cameras, on the other hand, records in digital, using the transmission and security features of the TCP/IP protocol. This means that its transmissions do not need to be converted or translated. IP cameras include any camera that is connected to the internet (or a local area network). They have two way communication, which means the camera can send data to the network and the network can send data to the camera as well.
Because IP cameras record in digital rather than analog, it results in a much higher capacity for higher resolution videos than CCTV cameras. The option of two way communication between an IP camera also means that there is more flexibility in how the camera is used (for example, someone can use the camera to listen and watch someone remotely and talk to the other person through the camera as well). CCTVs on the other hand can only record and send out data; the analog connection does not allow for two way communication.
Because IP cameras can use Wi-Fi to connect to the internet, their live recordings and feeds can be accessed from anywhere with an internet connection. This makes security very important; if you use an IP camera connected to the internet, make sure that you are using a strong password and a secure website.
IP cameras make live streaming to the web possible and fast. Some cameras also allow you to control the pan, tilt, and zoom of the camera from a remote location through the internet. This remote accessibility has brought a new dimension of security and surveillance to modern times, especially as the proliferation of smart devices, tablets, and personal computers has erupted over the past few years. Because we now have internet connection and a device to connect to the internet in our pocket or bag everywhere we go, having an IP camera that can be accessed and controlled over the internet has transformed the way we use these security and surveillance cameras.
Cost and Suitability
Because IP cameras have more capabilities, are typically more powerful, record in higher resolution, and use newer technology, they are commonly more expensive than CCTVs. However, camera sales have indicated a clear shift in favor of IP cameras because of their advanced capabilities and higher resolution.
In addition, CCTVs require a lot of storage to hold the recordings. With the advent of cloud storage and programmable cameras, IP cameras have the capability of only selectively uploading footage to the cloud (for example, in the case of a triggered home security alarm). This means that you don’t have to keep around an excessive amount of available local storage. Because the resolution of IP camera footage is higher, the storage space required can be very expensive if you decide to save an ongoing recording, 24/7.
IP cameras have really brought home security into the modern age. Who doesn’t want to check on their home from their smartphone–anywhere in the world? They incorporate multiple advances in modern technology to make the most of security’s value in peace of mind.
