The Difference Between IP and Analogue CCTV Cameras

Whether you are trying to protect your home or want to deter any potential burglars, there are two common systems used for video surveillance.  

The two camera systems include Analogue CCTV and IP cameras.  

While both serve the same purpose, they differ in the technology used to deliver your necessary security requirements.  

This article provides information on the difference between Analogue CCTV cameras and IP cameras.

What Is An IP Camera?

The IP surveillance camera is an Internet Protocol Camera that transmits real-time compressed digital image data wirelessly through the internet.

This can also be done via an ethernet cable connected to a broadband modem or router.

As IP cameras have their own IP addresses they can be easily added to any pre-existing network infrastructure.

Two main options are available for storing footage from IP cameras.

For single camera systems, IP Cameras generally have an SD card slot where an SD card can be inserted in to record footage.

For more advanced systems with multiple cameras, a software program known as a Video Management System (VMS) or hardware called a Network Video Recorder (NVR) can be used to record and manage the cameras.

IP cameras have an intelligent computer and analytics built-in for various functions, ranging from motion detection to line crossing, and even face detection.

As IP cameras are connected to the network, users are able to remotely view footage from virtually anywhere via the internet. They also offer a multi-user support option, meaning multiple users can control the surveillance camera from different devices.

What Is An Analogue CCTV Camera?

Analogue closed-circuit television cameras, more commonly known as CCTV cameras, are the traditional version of the surveillance camera.

These do not rely on an Ethernet or wireless connection.

Initially used for intrusion-detection purposes, the camera soon became more commonly used for video surveillance from the 1980s onward.  

The analogue footage from these surveillance cameras is sent to a Digital Video Recorder (DVR) via a coaxial cable, where it is converted to a digital format.

This system is useful because they are user-friendly and have low maintenance.

Moreover, advancement in Analogue CCTV technology and communication has improved their level of application.

What Is The Difference Between Analogue CCTV And IP Cameras?

1. Image Quality and Resolution

IP cameras generally have better image quality and advanced picture resolution than Analogue CCTV Cameras.

This enables the user to examine the finer details of recorded footage.

With higher resolution, IP cameras are also able to cover a larger area than Analogue CCTV cameras, which can only capture specific areas.

2. The Technology Being Used

The IP camera is a digital video camera, unlike the CCTV camera, which is analogue.

As a result, IP cameras offer an advanced recording capacity with high-quality footage.

However, Analogue CCTV systems transmit signals within enclosed systems, hence the name closed-circuit television.

3. Flexibility

Because Analogue CCTV systems are on a closed camera network, cable needs to be run specifically for the Analogue cameras back to the DVR.

This makes the placement of the camera vital to ensure the cabling is efficient. As IP cameras can operate on pre-existing network infrastructures.

This means they can be easily installed without any major re-cabling that may be required when installing Analogue CCTV cameras and NVRs.

Consideration does need to be taken into account on the impact installing IP cameras will have on any existing computer networks.

It is always advisable to liaise with the premise network system administrator prior to installing any new cameras.

4.  Broadcasting

IP cameras broadcast video footage digitally using a stream of data via a network or the internet.  

This data is sent to an NVR using internet protocol, and the connection is made using Power over Ethernet (PoE).  

PoE refers to a single cable being used for both the video transfer and power supply; therefore, removing the need for several cables.  

Analogue CCTV, on the other hand, sends the video signals to the DVR using coaxial cables and a power cable, where the signal is processed for viewing.  

The difference arises in that Analogue CCTV cameras require a direct link to the DVR, meaning if you wish to install these types of cameras, major cabling may need to be done.
