Difference Between CCTV and IP Camera
When choosing a security camera, you may come across two types of devices. The two devices in question are CCTV and IP cameras.
We often think of CCTV and IP cameras as the same product. Although they serve the same function, the two are actually very different. The differences result from the operation and functionality of the device.
So what is the difference between CCTV and IP camera? Which to choose? Keep reading the following article to find the answer Yes!
What is CCTV and how does it work?
CCTV stands for Closed Circuit Television. CCTV relies on analog signals to operate. Therefore, this product is often referred to as analog CCTV.
CCTV cameras are responsible for recording or capturing images. The image is then sent to the digital video recorder (DVR). CCTV sends analog signals to the DVR through a coaxial cable.
It can be said that the DVR is the center of all CCTV video. The task of the DVR is to convert analog video surveillance signals into video. The recorded data file is also stored in the DVR. Normally, the DVR is equipped with a hard drive for these video files.
Even to view live CCTV video, you need to use a DVR. Later, the DVR needs to be connected to the TV to view the recording.
Interestingly, thanks to technological advances, DVRs are now accessible over the Internet. Assuming you connect the DVR to the router and modem. However, not all DVRs support the ability to connect to the Internet. So it’s a good idea to do a little research before you buy.
CCTV is also relatively cheap compared to IP cameras. Also, it doesn’t need internet at all to work. CCTV is always analogous to DVR. Internet is necessary for those of you who want the monitoring feature from anywhere, not necessarily from home. Therefore, you can save internet costs by choosing analog CCTV.
So what are the disadvantages of CCTV? In fact, installing CCTV is relatively easy. You just need to connect the CCTV camera to the DVR with a coaxial cable. The problem is when you use multiple cameras in different corners of the house. That means you need to buy and install a lot of cables to connect to the DVR.
Also, the image quality of CCTV is inferior to that of IP cameras. No matter how good the CCTV is, the resulting image is only a maximum of 720 x 575 pixels. This means that the displayed image may be blurred.
CCTV is also not equipped with digital zoom capabilities. This means you can’t zoom in while it’s live. The point of view of CCTV coverage is also not wide. Many cameras are needed to cover many places.
DVR ports on CCTV are also limited. You may need two or more DVRs to cover multiple cameras. However, for small and not so large home use, a DVR is sufficient.
What is IP camera and how does it work?
Unlike CCTV, which relies on analog signals, IP cameras rely on Internet signals to work. IP in IP Camera itself stands for “Internet Protocol”.
How does the IP camera itself work? For the sake of simplicity, an IP camera can be thought of as a webcam, but it is Internet-enabled. The camera then takes pictures and the results can be viewed over the Internet.
If a DVR is required to operate analog CCTV, what about IP cameras? Professional IP cameras mainly use a device called Network Video Recording (NVR). The function of the NVR itself is similar to that of the DVR, which is to convert the video to a digital format and then store it on the hard drive located in the NVR.
Despite this, many providers do not sell IP cameras with NVRs, that is, only IP cameras. Interestingly, it still records without the need for the NVR. With the standard software, you only have to access the camera via the Internet.
Another difference with CCTV is that you can view images from IP cameras through mobile phones on laptops. As long as you are connected to the Internet and using standard software.
When using a camera similar to a webcam, don’t be surprised if the image quality of an IP camera can be very high. The average IP camera available has an HD resolution of 720p. There is also up to 4K!
However, you should pay attention to the quality of your Internet. If your internet quality is good, you can use a 4K IP camera. If it’s bad, just use the HD IP camera.
The perspective of the IP camera itself is also wide. The usual digital zoom function is also present in IP cameras. Therefore, you do not need many cameras for this type of security camera.
Interestingly, many IP cameras are accessible wirelessly. In other words, you don’t need a lot of wires to make it work.
One of the disadvantages of the IP camera itself is that it can be hacked. Since you use the Internet, hackers can get into your IP camera system.
There are suggestions to prevent this from happening. One of them is to set a very strong password so that it is not easy to crack.
Well that was the difference between CCTV and IP camera. Which one do you prefer to buy?
