Types Of CCTV: Which One Fits Your Needs?
CCTV, otherwise known as closed circuit television systems have become integrated into our modern lives, offering enhanced security and surveillance solutions for homes, businesses and public spaces. These systems come in various forms, shapes and sizes. Each type of CCTV camera can satisfy specific requirements and meet certain needs. In this blog post we'll explore the different types and help you decide on the best one for your premises.
Analogue CCTV Cameras
Before the advent of digital based solutions, analogue cameras were the traditional CCTV systems installed, using various wire systems to transmit video signals to an analogue monitor or recording device. In the digital world of today, they are highly cost effective and suitable for basic surveillance needs. Unfortunately as technology has evolved, the image quality that they output is much lower compared to the current standards. They are best used in small, confined spaces like stairways or hallways where a clear shot of activity can be captured.
Digital CCTV Cameras
With huge advancements in digital technology, CCTV cameras have largely replaced analogue systems due to their superior image quality and connectivity features. Some cameras can be connected to the Internet using the IP protocol in order to provide remote monitoring through a program or application.
Wireless CCTV Cameras
Some wireless CCTV camera models have the capability to connect to WiFi network systems to broadcast their recording without the need to transmit the image through hardwired data cables. They are mostly digital models that provide a whole host of connectivity options such as the ability to change the quality of media recorded, the ability of controlling the sound and microphone options and also setting timer options to bring the camera online or offline. They are extremely easy to install and are perfect for setups into material where wiring is extremely difficult. Always bear in mind that to use this type of camera, there should be a stable wireless network that is essential for reliable performance. Dead spots and thick walls can disrupt the signal.
PTZ (Pan-Tilt-Zoom) Cameras
PTZ cameras are known for their ability to pan, tilt and zoom, allowing for flexible monitoring of a wide area. This makes them especially useful for monitoring large areas such as shopping centres, car parks and stadia. These setups are usually controlled remotely and are ideal for tracking people and objects in real-time. They are commonly used as part of a larger surveillance system network. These cameras can also record large amounts of data in very high quality images.
Dome cameras are named after their dome-shaped housing, which makes them discreet and less noticeable when compared to other cameras. They often have a setup that allows for 360 degrees rotation of the camera module and are small and compact enough to record down onto the surface allowing for complete field of view on a large area. Some of the domes can come with vandal-resistant features to prevent the dome from being shattered or sprayed on to try and cover the camera's tracking path. They are used for both indoor and outdoor surveillance.
Bullet cameras are named due to their cylindrical dome being shaped like a bullet. The camera systems that are inside the dome usually record at very high quality and are able record at long distances, making them extremely useful for deciphering difficult images. They are often used across a variety of outdoor settings such as streets, car parks and more.
Day / Night Cameras
Some cameras that are in place have the ability to cycle through recordings during the day and night. These cameras are equipped with infrared (IR) LEDs to capture clear footage in a night vision configuration. This can make them useful to capture shots of individuals and objects during the dark, making it very difficult for potential suspects to hide. These cameras are perfect for 24/7 surveillance in areas which require constant monitoring.
When choosing a CCTV system, you need to consider your specific security needs which include requirements such as the location of installation, number of cameras, type of monitoring needed and any additional equipment needed to complete the system such as cabling, fixtures and more.
