CCTV cameras act as a deterrent to criminals, reducing the likelihood of unauthorized entry to your property, and they provide crucial evidence if an incident occurs. Additionally, they assist in identifying suspects and supporting criminal prosecutions.
Various types of CCTV cameras are available, including dome, bullet, turret, and C-Mount cameras. These types differ in their design, housing, and the field of view they offer.
Analog
While analog cameras are not as popular as IP security cameras, they still remain a viable option for those looking to upgrade their wired CCTV system. Analog cameras typically transmit their data over coaxial cable at standard definition (SD) video quality. When paired with an HD CCTV recorder, however, an analog camera can produce higher resolution video footage.
Analog camera systems offer a cost-effective solution with simpler installation requirements. As they don't rely on network infrastructure, they are less demanding on network bandwidth. Additionally, they can be centrally managed through a single recording device, making them suitable for multi-site monitoring.
Conversely, IP cameras, while generally more expensive upfront, deliver superior image quality, advanced features, and remote accessibility. They require a dedicated network infrastructure but offer greater flexibility in terms of system expansion and integration with other technologies.
Unlike analog cameras, IP cameras use data encryption to protect their information and reduce the risk of hacking. Additionally, they can be installed in weatherproof casings, which are essential for outdoor surveillance applications.
Another important consideration when choosing an IP security camera is its transmission capabilities. Depending on your needs, you may need a camera that can broadcast over long distances or one that can operate in poor weather conditions.
Lastly, it’s important to consider the storage requirements of an IP security camera. Its higher resolution and frame rate generate more data, increasing your storage needs. To address this, you can opt for a camera with compression capabilities or use a NAS to store and compress data.
Ultimately, both analog and IP cameras have their pros and cons. The best choice for your metro business will depend on your existing CCTV system, your current and future needs, and your budget.
IP
IP cameras communicate digitally over a secure Internet connection, transmitting live footage to monitoring systems where it can be processed, organized and viewed. They’re a great choice for businesses with offices or remote sites, enabling teams to observe key areas from any location using a secure smart device. They’re also more resistant to hacking and are able to use a variety of frame rates to suit the needs of specific applications, as well as automatically sending video data to storage devices during predefined events.
Network CCTV cameras offer a versatile security solution that can be deployed both indoors and outdoors. These advanced devices come equipped with a wide range of features to enhance their functionality, including night vision capabilities, wide-angle lenses, and anti-theft safeguards. Some models even feature infrared illuminators to capture high-quality footage in low-light or dark conditions.
For indoor environments, options like dome or turret cameras are designed with a discreet, unobtrusive appearance that seamlessly integrates with the surrounding decor while still providing reliable, high-definition surveillance.
As network-based systems, these CCTV cameras offer several advantages over traditional analog setups. They operate over a secure, private wired network, which generally makes them more reliable and less susceptible to interference. Additionally, many network CCTV cameras utilize Power over Ethernet (PoE) technology, which allows them to receive both power and data transmission through a single Ethernet cable. This streamlines the installation process, reduces the need for extensive cabling infrastructure, and ultimately helps to lower the overall cost of the security system.
Whether you're looking to monitor indoor or outdoor areas, network CCTV cameras provide a versatile, high-performance security solution with a range of advanced features to meet your needs.
When deciding on an IP camera system, it’s important to consider your security requirements and the size of your site. Some models are able to connect directly to your existing local area network, bypassing the need for a central NVR to manage recording and alarms. These cameras offer a more streamlined installation and are ideal for larger sites with extensive coverage needs.
For a more complete and integrated security solution, you can pair an IP camera with a networked NVR, which will manage alarm management, record video, and allow you to control your cameras remotely. This type of CCTV system is particularly popular in locations with a higher risk of theft and crime, such as retail stores or warehouses.
PTZ
A PTZ camera, or pan-tilt-zoom camera, has motorized components that allow it to pan left and right, tilt up and down, and zoom in and out. These units are useful for surveying open spaces that require a 180- or 360-degree view, as well as tracking and investigating suspicious activity. PTZ cameras can also be programmed to follow motion or stay fixed. These features make them ideal for use in guard stations, where operators can operate cameras via remote camera control.
When choosing a PTZ camera, it is important to consider its range of motion and its ability to capture clear images in low light conditions. Other features to check include the camera's audio capabilities, which can be one-way (allowing you to listen) or two-way (allowing you to talk to people around the camera).
Some PTZ cameras are weatherproof and can withstand physical tampering and vandalism, making them suitable for outdoor surveillance applications. They may also be integrated with other security systems, such as alarms and motion detectors, and they can be remotely monitored and controlled through a network connection.
When choosing a PTZ camera, you should also examine the camera's power requirements and communication possibilities. Some PTZ cameras use direct power supply, while others use Power over Ethernet technology, which allows the camera to send data and power via a single Ethernet cable. Some PTZ cameras are even battery-powered, which lowers wiring costs and allows them to be put farther away from a power source.
Another factor to consider when choosing a PTZ camera is command latency, which is the time it takes between an operator sending a control signal and the camera's field of view (FOV) adjusting on the monitor. Ideally, you want to select a PTZ camera with low command latency to ensure that the camera can react quickly and accurately to events taking place in real-time.
Infrared
Infrared cameras do not use visible light but instead detect emitted or reflected infrared radiation to produce images. This makes them ideal for night-time imaging and other applications that require low-light conditions. They can also detect the presence of a person or object even in complete darkness. They have become popular in home security systems and can provide valuable evidence in the case of a break-in.
Most infrared cameras have a cooled infrared detector, which helps improve image quality by increasing the sensitivity of the sensor. Cooled sensors are often made of vanadium oxide (VOX) or amorphous silicon (a-Si).
These detectors usually consist of pixels that convert infrared light into an electrical signal. Changes in this resistance are measured by reading electronics connected to the camera and converted into a temperature reading. Compared to uncooled cameras, cooled cameras require more time for the pixels to warm up before producing an image.
Uncooled IR cameras are usually more cost-effective than cooled cameras. However, a cooled camera will produce a higher-quality image and is better suited for certain inspection applications. For example, a cooled camera is required for inspections of electrical bus trays, which must be kept at a low temperature to avoid the risk of fire.
A cooled camera must be cooled with a Stirling engine cryocooler, which is more expensive than a peltier cooler but offers superior performance. However, the cooling system may add to the overall camera size and weight.
Using a cooled camera for thermal imaging can save energy, especially in buildings where heat is not distributed evenly. It can also help reduce costs by identifying areas of energy waste in HVAC systems and improving overall building efficiency.
Infrared cameras can also be used for medical imaging, by detecting changes in blood flow or inflammation. They can also be useful for agricultural and wildlife monitoring by identifying plant health and pest infestations based on temperature differences.
Infrared technology is not as advanced as the digital image sensor used in visible light cameras, but it is an essential tool for many types of cameras. There are three main types of cameras with infrared: point and shoot, DSLRs, and mirrorless. Point-and-shoot cameras are perfect for beginners and those on a budget, as they are easy to use and inexpensive. DSLRs are better for professional photography and offer more control over settings. They are more expensive than point-and-shoot cameras, but provide exceptional image quality.

The ability to monitor and record activities in real-time not only acts as a deterrent to potential criminals but also provides invaluable evidence when incidents occur. High-quality footage captured by CCTV cameras has proven instrumental in helping law enforcement identify suspects and prevent crimes.
For instance, across Auckland, hundreds of cameras are linked to a central hub at Smales Farm, where live video data is utilized for traffic management and other critical functions, showcasing the widespread impact and utility of CCTV systems
1. Security Monitoring of a Large Electrical Cable
CCTV systems are a valuable tool for deterring crime, and can help capture high-quality evidence to support police investigations and court proceedings. However, it’s important to engage professional CCTV installers in Auckland to ensure that the right solution is implemented for your property. A qualified security integrator will assess your property layout and security needs to recommend the best system to protect you against threats.
Feeling safe in your home is a fundamental human right, but for many people in urban areas this can be undermined by persistent disturbances from their neighbours or other neighbourhood activities. CCTV is an effective way to monitor neighbours’ activities and catch criminal activity on video. It can also provide peace of mind for homeowners, allowing them to monitor their own property and prevent damage from occurring.
Residential CCTV installation projects can cover a wide range of monitoring needs, such as keeping an eye on children as they arrive and leave for school, overseeing car parking, and tracking deliveries in the driveway. Recently, we completed a project for a household in West Auckland that was facing ongoing disturbances from neighbors, including physical and verbal abuse and objects being thrown over the fence. To enhance security and monitor the neighbors' behavior, we installed two CCTV cameras at the property.
Most Aucklanders aren’t aware that they’re constantly being surveilled by CCTV cameras – the city has thousands of them across the streets, schools, and business sites. CCTV can record the activities of neighbours going about their daily lives, couriers dropping off packages, and cars driving past - all without anyone knowing they’re being recorded.
CCTV systems serve a broad spectrum of purposes. In traffic management, they monitor vehicle flow, identify congestion points, and enforce traffic regulations. Meanwhile, law enforcement agencies utilize CCTV for crime prevention, investigation, and public safety.
To ensure transparency and respect for privacy, organizations deploying CCTV systems must clearly communicate their surveillance activities. This includes informing the public about the system's purpose, who operates it, and how collected data is used.
New Zealand’s Privacy Act states that people have a right to request the details of what information is held about them. This is a vital principle that should apply to CCTV as well as any other personal information.
2. Residential Security
Whether you live nearby, commute through the area, or deliver packages, privacy concerns regarding CCTV cameras are important. Although interest in residential security has historically lagged behind that of the US, it is now increasing, according to retailers like Bunnings, which offers 65 home security products. The company’s New Zealand head of trading notes that people are purchasing cameras because they see their friends and neighbors doing so, and more affordable options have become available.
The use of cameras in the home is a powerful deterrent to criminals, especially when the presence of CCTV is advertised by signage. It acts as a psychological deterrent, creating stress for would-be burglars by making them feel that their actions are being recorded. This can help to deter crime, but it also provides police with valuable evidence that can be used in investigations and prosecutions.
In the 2020s, high-quality CCTV cameras have become increasingly sophisticated, providing detailed, high-resolution imagery that can capture valuable information about suspects. These advanced cameras are capable of recording critical details such as the suspect's clothing, facial features, physical attributes, any weapons they may be carrying, the vehicles they are using, and even their distinctive gait or walking patterns.
This level of visual clarity allows law enforcement to effectively track the movements of criminals, trace their origins and destinations, and identify potential associates. There are numerous cases where high-quality CCTV footage has proven instrumental in helping police successfully investigate and prosecute a wide range of criminal activities.
The enhanced capabilities of modern CCTV systems have significantly improved the ability of law enforcement to gather the necessary evidence to identify, apprehend, and convict suspects. By leveraging these advanced surveillance technologies, authorities can better protect communities and hold perpetrators accountable for their actions.
While individual properties installing CCTV is a good deterrent, it's more effective in combination with other measures such as fences, gates and bollards (popular against ram raids) to stop criminals from getting close to the property. And when multiple properties in the same area have CCTV, this creates a long continuous trail of footage that police can follow to catch and prosecute criminals.
Auckland Transport takes reasonable steps, including through the use of signage and publication on its website, to make people aware that CCTV is operating on their network. Footage is stored for 7 days and anonymised metadata is kept longer for network efficiency purposes. People can request access to this data, and the privacy commissioner can investigate complaints.
3. Traffic Management
CCTV cameras are powerful crime prevention tools, enabling remote monitoring and providing high-quality evidence to fight crime. They can also block excessive visibility and help create a sense of security in commercial and residential areas. This can reduce the risk of theft, vandalism and other crimes.
However, it is important to remember that CCTV can be used for many different purposes, not just crime prevention. It can also be used for traffic control, to reduce congestion on busy streets and roads. This can be achieved through the use of traffic lights and intelligent traffic management systems to manage road use.
A number of CCTV systems are used by Auckland Transport (AT) to monitor traffic conditions in the city, particularly during rush hour. These cameras can capture a wide range of information, including vehicle counts and speed profiles, helping to inform policymakers, urban planners, and transportation authorities about the effectiveness of their infrastructure investments.
In addition, traffic camera data can be compared to historical traffic trends to improve traffic flow and enhance transport efficiency over time. This type of traffic analysis can also help to identify specific bottlenecks and other issues that need to be addressed.
This is a crucial part of making cities more sustainable by improving their ability to handle the increased demands on local infrastructure. Ultimately, this will lead to improved air quality and reduce the amount of stress on local communities.
CCTV is also an effective way to provide real-time traffic information to motorists, especially in areas with a lot of traffic problems such as construction zones or unforeseen chaotic events. This information can be shared via digital signs, mobile apps, or other means to let drivers know what to expect.
Whether you want to upgrade your current CCTV system or install a new one, it's always ideal to work with professional CCTV installers in Auckland. This ensures that your cameras are properly mounted and configured, allowing them to work optimally. They will be able to examine your property's layout and security requirements and offer the best option for you. They will also assist you in selecting the best type of camera for your unique needs.
4. Commercial Security
Commercial security cameras provide business owners with a variety of benefits. They serve as a visible deterrent to intruders and vandalism and provide high-quality evidence for police investigations. Many CCTV systems are also equipped with alarms that activate when motion is detected, helping to scare off intruders and deter crime.
CCTV can also be used to prevent unauthorized access to secure areas such as warehouses and office buildings. For example, cameras can be installed outside loading docks and elevator entrances to prevent employees from entering these areas without an authorized pass. They can also be set to send an alert to the central control room if anyone attempts to breach security.
In addition to acting as a deterrent, CCTV can also be used for surveillance of large areas like warehouses, office buildings, and parking lots. These cameras can be monitored remotely via smartphones and computers, providing business owners with a complete overview of their property at all times. This ensures that the property is safe from theft, burglary, and other security risks.
A security camera system can also be used to track the movements of staff and customers, allowing businesses to monitor activity at all times. This allows companies to respond quickly and efficiently in the event of a security threat, improving overall safety and productivity.
CCTV is also a cost-effective alternative to hiring security personnel. A single CCTV installation can cover an entire area and allow remote monitoring, while reducing the need for expensive salaries, insurance policies, and other costs. Most modern CCTV systems also work on cloud-based storage, making them more cost-effective than traditional hard drives.
Some Auckland people are concerned about the influence of CCTV on their privacy, however it is crucial to remember that every monitoring system has a purpose. The system's implementation should be considered, as research has shown that indiscriminately surveilling an area can have a negative impact on certain people, such as women, who may feel more vulnerable due to a "placebo sense of safety" caused by the presence of cameras.
