Surveillance camera systems have been around for many years, but they are only just becoming popular with businesses that need them now more than ever. Every brand claims it has high definition and night vision, and then sorting through all the various claims can be pretty confusing. What exactly is night vision? How does it work?
Surveillance camera systems first started as CCTV, or Closed Circuit Television. They are still referred to as such even though most modern devices are IP (Internet Protocol), which means they can transmit their video footage over the Internet. CCTV uses an electrical circuit to record a person’s movements. The camera system can either send the images over the Internet wirelessly or send them through a cable or network of optical cables. These IP cameras, or Internet protocol cameras, work by picking up video from one terminal and then displaying it on another terminal, usually through a monitor. They have a built-in data storage facility, holding up to 2 terabytes (two gigabytes). A single IP camera can provide up to ninety-five hours of surveillance.
Night vision IP cameras allow surveillance camera systems to see in the dark, so long as there is no light interference. This includes motion detection and even a night vision capability if the camera has a night vision module built into it. A sound surveillance camera system will have the ability to switch between different image intensifiers for various conditions, such as low light, bright light, or infrared light.
With the advancements in IT and large storage capacity, and high-speed networking, thermal cameras are ideal for a surveillance system. Thermal imaging captures images at night using an Infrared illumination source, which is sensitive to heat patterns. This allows the camera to view the scene without adjusting the filter on the camera lens’s front end. This means you get an accurate picture, which helps facial recognition, night vision, etc.
Nesting, surveillance, and monitoring can all be done with a single wireless device or nest of routers. The routers can act as a bridge to multiple wireless devices. The device will serve as a hub, where all of the devices connect to the hub. In this way, you can view your test plans, view areas of interest, set up permissions, control lighting, heating, ventilation, and other functions remotely.
This system is used for various surveillance applications, including CCTV, remote monitoring, surveillance of retail stores and premises, and security of sensitive and protected sites, information, and assets. For outdoor surveillance purposes, the most popular systems available are the 7 foot, two-way outdoor weatherproof camera. This camera is connected via two-way radio to a centralized recording console. Most devices support direct connection to an optional external IP network. These devices are commonly used in malls, high-risk business places, banks, and airports to monitor and record outdoor activities.
The NVR Security Camera is another type of NVR security camera that utilizes infrared technology to provide a true night vision capability. This is a very compact unit that can be easily concealed within a building structure. When the camera emits infrared light, it will trigger the night vision device. This device has a two-way radio and built-in rechargeable battery to allow numerous calls during the same view range.
The NVR Security Camera has many advantages over other types of cameras. For example, with an NVR Security Camera, there is no need to use a flashlight because the infrared illuminates the area in front of the lens. The video quality will vary depending on how the camera is configured, but most cameras can at least 1080p resolution. If you want optimum video quality, you should purchase an NVR Security Camera with Extreme Video Resolution (EVA).
