If you are in the market shopping for a CCTV surveillance system for your home or business, you are sure to come across the terms, “IP Cameras,” and “CCTV Cameras.” To choose the right camera for your security system, it pays to be aware of both these popular types of cameras – features, installation setup, limitations, benefits and more.
Here, in this guide, our security experts here at Eurovigil compare and contrast both these popular choices, helping you find the right security camera that suits your specific needs.
What are IP Security Cameras?
IP (Internet Protocol) cameras are digital video cameras that transmit captured video footage using an internet-connected computer network. Better picture quality, ability to connect several cameras in the network and advanced recording capabilities are some of the interesting features of an IP camera.
What is CCTV Cameras?
CCTV cameras are also known as analogue cameras and they transfer the recorded video signals in analogue form (as electric signals) to the connected DVR (Digital Video Recorder). Since signals are sent electrically, each analogue camera in the CCTV network must be physically connected using coaxial cables to the DVR.
To Note: Today, CCTV camera has become an umbrella term, and today a CCTV system may include IP CCTV cameras or Analogue CCTV cameras, depending on the requirements.
Head-on Comparison of CCTV and IP Security Cameras:
1. Initial Setup
IP security system cameras use an NVR (Network Video Recorder). Since, both the NVR and the cameras in the network communicate via the internet, there is no need for physical wiring connecting these devices.
Analogue CCTV cameras, on the other hand, require a DVR that captures the recorded videos in a hard drive. To set up the CCTV system, the cameras and the DVR has to be connected via coaxial cables.
2. Power Supply
IP security cameras require minimal wiring. It uses PoE (Power over Ethernet), and there’s no need for extra power cables. This cable can also be used to transmit two-way audio channels.
CCTV cameras, on the other hand, require two separate cables, one for power supply and the other for data transmission.
3. Compatibility and Extendibility of the CCTV Surveillance System
One of the biggest perks of using IP security cameras in your surveillance system is that you can quickly add additional cameras to the network to cover any blind spots. Since, the wiring is minimal, extending the security network is a breeze.
Surveillance systems that use analogue CCTV cameras have a fixed number of cameras in the system. If you need additional coverage, then you can set up a separate CCTV circuit to cover the extended area.
4. Image Quality
It all depends on the resolution of the camera you are using. Not all security cameras offer the same resolution. For instance, the Eurovigil I View IP 200 (an IP Camera) offers HD-quality with an image resolution of 1920 x 1080, while the Eurovigil I View HD 500 PTZ (a CCTV camera) also offers similar high-resolution quality.
As you can see, the image quality depends on the particular model of camera you are choosing, regardless of whether it’s a CCTV or an IP camera.
5. Remote Access
Both IP and analogue CCTV cameras can work remotely. But, what differs is the method of remote access. For CCTV cameras, the camera sends the video to the DVR, which then transmits remotely via the internet. On the other hand, an IP camera can connect directly to the internet providing remote access.
Since CCTV cameras belong to a closed circuit, the videos are not available publicly making them highly private and secure. While it’s true that IP surveillance cameras transmit video footages via the internet, you can make it secure by using an encrypted VPN or a private network.
Quick Comparison Chart of IP and CCTV Camera
|IP Camera||CCTV Camera|
|Video is recorded on an NVR (Network Video Recorder) and local SD cards||Video is recorded on a DVR (Digital Video Recorder)|
|Uses Wifi and Bandwidth for video transmission||Uses TV broadcast (analogue) signals for transmission|
|Wiring is minimal||Individual wiring required for each camera|
|Single wire for data transmission and power supply||Separate wires for data transmission and power supply|
|Easy to include additional cameras to your CCTV system||The number of cameras in the CCTV system is restricted|
|Remote access directly via the camera||Remote access possible via the DVR|
|Privacy can be enhanced by using encrypted VPN or private networks||No privacy concerns|
Which Surveillance Camera Should I Choose?
There’s no single best IP camera or CCTV camera. It all depends on your usage requirements. Irrespective of which surveillance camera you choose, make sure to select one based on other criteria apart from the cost. Look for security cameras that are low maintenance, offer backward compatibility and are easy-to-install and use.
