In recent decades, security systems have grown more and more vital in both domestic and business environments. There is a vast choice of systems available and it can be difficult to choose which type of system is right for you. If you have ever searched online on the topic, you must have heard of two types of cameras, CCTV cameras and surveillance cameras. But what makes the two different? So, how do you know which one to use or which one is suitable for your business or personal use? In this article, we are going to explain the difference between CCTV and Surveillance cameras, the advantages and disadvantages of both and then help you decide.
In this article, we will explain to you the difference between CCTV and Surveillance cameras, their pros and cons, and then help you make that choice. There will also be related topics like system components, installation issues and frequently asked questions.
It is important to understand the basic idea of a security camera system before discussing the differences between them. The reason for installing CCTV or surveillance (IP) cameras is to stop criminal activities from taking place, record events and act as evidence if they take place. The infrastructure and technology used to accomplish this are very different.
The use of the word “CCTV” has been synonymous with video surveillance in general, traditionally. When speaking of a security camera system in general terms, people may use the term ‘CCTV camera. Technically, though, CCTV is a closed circuit that sends video signals from the cameras to the monitors (and perhaps a recorder). In other cases, surveillance cameras or IP cameras transmit, receive and store video data via a digital network, frequently the internet, giving them more flexibility and versatility.
CCTV stands for Closed Circuit Television. It operates as a private, closed system, meaning the video signal is not publicly transmitted. Here is a simple breakdown of how a typical CCTV system might be set up:
CCTV is also frequently thought of as reliable and consistent coverage, particularly when it is maintained properly. But if they have not been upgraded to hybrid or digital systems, these may be constrained by older technology.
IP (Internet Protocol) cameras or network cameras are surveillance cameras that record and relay video data via a digital network. They do not just use coaxial cables and closed networks; they employ Ethernet cables (Cat5, Cat6, etc.) or even wireless (Wi Fi). Here’s a simplified overview of the typical operation of an IP-based surveillance system:
The table below summarizes the most important distinctions between the two technologies.
The traditional CCTV systems involve analogue video signals, which are sent via a coaxial cable. These signals are passed through a DVR that then translates them into digital form to be stored. The system is a closed circuit; it records from the camera to the monitor/recorder without being broadcast publicly.
Surveillance cameras (IP cameras) transmit an image by digital signals through a computer network. All cameras are connected with their own IP address and video is processed locally on each camera before being sent to an NVR or cloud server. This gives much greater flexibility as cameras can be easily integrated into an existing network.
The typical resolution of Analog CCTV cameras is 960H (approx. 0.4 megapixels). But newer HD analog technology, such as HD TVI, HD CVI, and HD AHD, can deliver up to 1080p or even up to 4K resolution. While significant strides have been made, the typical IP camera will produce better image quality. Most IP cameras are 2 MP (1080p) and can reach 4K (8MP) or more. This is important for face detection, license plate reading and large area details.
One of the biggest differences is remote access. A stand-alone CCTV system cannot be accessed from a network or remotely over the internet, unless it is connected to a network. If you want to watch footage remotely, extra equipment and setup are necessary.
Most of today’s surveillance cameras are made for distant viewing. Whether you’re on your phone or using a browser, you can access live streams, recorded video, and get alerts from anywhere in the world with internet access. A significant benefit for homeowners or business owners with lots of travel or more than one home.
Analog CCTV cameras must use two cables – one for video transmission (coaxial cable) and the other for power. This can make installation more complicated, particularly for bigger systems.
Power over Ethernet (PoE) can be used to transmit both power and data via a single Ethernet cable with IP cameras. This makes installation easier, causes less cable nuisance and makes it easier to place cameras in optimum positions.
Modern IP surveillance cameras often include built-in analytics. These can include:
Traditional CCTV systems generally lack these features. Some hybrid DVRs can add basic motion detection, but they cannot match the intelligence of a modern IP camera.
CCTV systems record to a DVR, which stores footage on a hard drive. The recording is continuous, which means a large amount of storage is required. However, DVRs are generally reliable and have been used for decades.
IP cameras record to an NVR or directly to cloud storage. NVRs are more flexible, allowing for motion triggered recording, scheduled recording, and easy export of clips. Cloud storage offers off site backups but may come with monthly fees.
Both CCTV and surveillance cameras come in various form factors and designs. Understanding the different types will help you choose the right camera for your specific application.
When planning a security system, you will need to understand the core components involved.
The choice between CCTV and surveillance cameras depends on your specific needs, budget, and technical expertise
For smart buildings, IP cameras are generally the better choice. Traditional CCTV systems lack the integration capabilities required for modern building automation. IP cameras can connect to access control systems, lighting controls, and alarm systems. They can send real time alerts to facility managers and integrate with video management software (VMS) for centralized control.
In Australia, video surveillance systems must comply with relevant standards and privacy laws.
The Australian Standard for Closed Circuit Television (AS 4806) defines best practices for designing, installing, and maintaining CCTV systems. Compliance with AS 4806 is recommended for businesses and public facilities. Additional standards such as AS/NZS 62676 provide guidelines for video surveillance system performance and environmental suitability.
Australia does not have a single national surveillance law governing residential cameras. However, state and territory surveillance device acts apply. For example, under the Surveillance Devices Act in various states, it is an offence to knowingly install a camera that records private activities without consent. If your camera captures a neighbour’s private space or records conversations, you may be committing an offence. It is good practice to position cameras to only monitor your own property and to place clear signage if cameras are visible.
Several major brands dominate the Australian security market. These include:
Costs for CCTV and surveillance camera installation vary depending on system size and complexity.
Ongoing costs may include cloud storage subscriptions (often AUD 5 to AUD 15 per month per camera) and maintenance.
The decision to install a CCTV camera or a surveillance camera depends on a person’s requirements. IP-based surveillance systems are the best choice if you are looking for high definition video, remote access and smart analytics. A traditional CCTV system may be enough if a simple, reliable, low cost local monitoring solution is required.
For Australian homeowners and businesses, other factors to consider are compliance with Australian standards, weather resistance (IP65 for outdoor applications or above) and privacy legislation. A licensed security installer can help you create a system that fits your needs and circumvents legal issues.
It is important that you decide whether to use CCTV or surveillance cameras and know that they are installed correctly, maintained and used safely. Security systems that are properly designed give you peace of mind, deter crime and capture important evidence if necessary.
A security camera is often used for active monitoring and alerting, while a surveillance camera continuously records for passive observation. In practice, the terms are used interchangeably, but technically surveillance cameras are a subset of security cameras.
Not exactly. CCTV is one category of security camera. All CCTV cameras are security cameras, but not all security cameras are CCTV (for example, IP cameras and wireless cameras).
CCTV stands for Closed Circuit Television. It refers to a system where video signals are transmitted over a closed, private network.
IP cameras are generally better for resolution, remote access, and smart features. CCTV (analog) may be better for simple, low cost, non networked installations.
Yes. Traditional CCTV systems do not require an internet connection. They record locally to a DVR and can be viewed on a local monitor.
Many modern IP surveillance cameras include microphones. However, recording audio without consent may breach Australian surveillance device laws in some states.
For reliable face identification, a minimum of 2 megapixels (1080p) is recommended, but 4K (8 megapixels) is better for larger areas.
Storage duration depends on hard drive capacity, number of cameras, resolution, and recording mode. Typically, systems store between 7 and 30 days of footage.
For Australian homes, weather rated IP cameras from brands like Dahua, Hikvision, Swann, or Arlo are popular. Consider solar powered options if cabling is difficult.
