In today’s scenario, every institute or organization require security in every nook and corner of their premises, thus CCTV cameras became indispensable. Every institute, office, school, college and even residences prefer to install a CCTV camera in their premises. With the increasing demand for CCTV Cameras, the technology is also evolving. There is a variety of CCTV cameras available for purchase, ranging from Analog CCTV cameras to IP-based CCTV Cameras. Amid so many choices, you may want to make an informed decision based on the need and budget of your organization. For this purpose, we have described in detail the basic differences between an Analog and IP-based CCTV camera.
Analog vs IP- Based Camera: The Difference
The major difference between Analog and IP-Based CCTV Camera is the method by which they record a video and deliver it. In case of Analog Cameras, they send a signal over a coaxial cable to the Digital Video Recorder. The DVR further converts the video’s analog signals to digital signals, compresses the file and stores it on the storage device. Monitors are also attached to receive the video output. The DVR can also be connected to an internet connection to broadcast the video over the internet.
On the other hand, IP-Based CCTV Cameras record the images digitally. They can send and receive the data directly to and from the computer network rather going through a DVR. Some cameras even operate via POE-switch, which transmits the data and power simultaneously.
Both Analog and IP-Based CCTV Cameras have their own advantages. Depending upon the budget and requirement, one can decide what type of camera will be sufficient for your security and surveillance requirement.
Advantages of Analog CCTV Cameras
There are a number of advantages to an Analog CCTV camera which makes many people still choosing them. Some of them are listed below:
- Analog Cameras are much cost-friendlier as compared to their digital counterparts on a per camera basis.
- They are easy to set up. The installation process is much straightforward and doesn’t require exquisite technical training to install an Analog CCTV Camera.
- The video recorded by an Analog CCTV Camera are much smaller in size. They are transmitted to the DVR through a coaxial cable instead of LAN. So transmission also doesn’t cost much bandwidth. On the other hand, DVRs only transmit the information and use the bandwidth when someone is watching the video instead of on a more constant basis.
Advantages of IP-Based CCTV Cameras
There are multiple benefits of having a Digital CCTV Camera instead of an Analog one. Here are some of them to mention.
The image quality in IP-Based CCTV Cameras is significantly higher than the Analog one. Multiple IP-Based CCTV Cameras can transmit videos in high definition resolution. Such cameras also process the Digital Zoom feature which allows the users to see intricate details in the video in utmost clarity.
The coverage offered by IP-Based CCTV Camera is much times wider than the Analog Cameras. Hence, in case of IP cameras, one may require lesser units to cover a larger area.
Fewer Cables Needed
Unlike Analog Cameras, the IP-Based CCTV Cameras require much lesser cables. In case of Digital Cameras, multiple units can be connected to each other via switch and then the switch is connected to the NVR using a single cable. The data and power are transmitted through a single cable.
Facility of Power Over Ethernet
Instead of connecting two cables for power and data transmission separately, one single cable can serve the purpose of both. Power Over Ethernet switches enable your signal cables to transmit power as well, thus ruling out the need of two cables.
Facility to View Live Feed Remotely
Unlike the Analog CCTV Cameras, IP-Based Cameras offer the facility to the users to monitor the live feed remotely from any location. They are not susceptible to interferences like their analog counterparts.
All the videos transmitted from the IP-Based Cameras are encrypted, which means they are not prone to cybercrime and data theft. Most of the Digital Cameras have encryption built-in so that the users don’t have to worry about their data being misused.
About Globus CCTV Cameras
Globus CCTV Cameras are designed in order to match pace with the ever-changing technology. Our latest video analytics software has features to suit everyone’s diverse security and surveillance requirements. Our CCTV Cameras are enriched with Artificial Intelligence to monitor and analyse situations and raise necessary alarm when required.
Globus CCTV Cameras combine the technologies of Infrared and Starlight to give our users best image performance even in low light. Starlight technology enables the CCTV cameras to render colour and clear images even in extremely poor lighting conditions. This way, the users can analyse the recorded videos better for improved safety.
All the models of Globus CCTV Cameras support H.264+ video compression technology that compresses the video recordings without compromising the picture quality. It is a well-known video compression standard for high definition video output. The compressed videos are not only superior in quality, but also require half the storage space and network bandwidth. Through this video codec, the videos are able to retain their quality while talking up only half of the storage space.
Our Video Analytics Software also comes with features like facial recognition, object removal, perimeter intrusion, people count, loitering, etc.
Our Security and Surveillance product line-up includes: Analog Cameras, IP-Based Cameras, Bullet Cameras, Dome Cameras, PTZ Cameras, Fish Eye Cameras, NVR, DVR, Switches, Body Worn Camera and Mobile Surveillance.
