Digital & Network Video Recording Solutions-When deciding on what kind of security system you want, most people only pay attention to the quality of cameras they want to utilise. However, they’re forgetting the most important part, the recording device.
Digital Video Recorders (DVR) and Network Video Recorders (NVR) are connected to CCTV cameras and are used to record and store information in a single unit.
DVR’s & NVR's enable you to record footage and then view the footage at a later time that suits you. It is also useful should your property have been burgled or a criminal offense committed at your premises, because footage of the event will be recorded on your DVR or NVR's hard drive (HDD) and can be supplied to police to assist in a criminal arrest.
DVR’s & NVR's enable you to view your property anytime, anywhere with the right software via a network connection from your smartdevices, laptop or PC.

THE DIFFERENCE BETWEEN ANALOG, HDCVI & IP SECURITY CAMERA SYSTEMS
With technology advancing everyday, we often have to do extensive research before knowing exactly which product is right for us. When it comes down to surveillance technology and types of surveillance systems, there are a few technologies to choose from. With terms like Megapixel, TV Lines, 960H, POE, BNC, Cat5e, 1080P and various other terms, it is hard to know what they all mean and what is the difference between each?
Almost all surveillance systems can be broken down into three main categories: |
ANALOG SURVEILLANCE SYSTEMS
Analog systems are what began the surveillance industry and it is the oldest CCTV platform, which is still around today. It provides images at resolutions of 720h x 562v, providing video images up to 600TV lines, which can often be pixelated and grainy. It is the most proven platform, which is still available for a low price, but will most likely be phased out very soon due to advanced high definition platforms such as HDCVI & IP.

HDCVI SURVEILLANCE SYSTEMS
HDCVI stands for Composite Video Interface. This new techology allows a simple solution for the consumer who is looking into getting their first surveillance system or already has a system installed and wants to upgrade to high definition without breaking the bank. HDCVI blends IP and Analog technologies into one easy setup and affordable option. It is a low cost alternative to IP and can utilise longer cable runs, the equipment is easy to use, audio/video and control signals are built together and you get 1080P resolution. HDCVI works by sending high definition audio and video over regular coaxial cable at distances of up to 152 meters. This new technology allows the existing coaxial cabling from your analog system to be used. All that needs to be done is, plug your new HDCVI DVR & Cameras into the existing cabling to get fully high definition pictures at a fraction of the cost of IP equipment.
We would recommend this surveillance platform, if it is your first surveillance system or if you already have an analog system and are not happy with the quality of your cameras.

IP SURVEILLANCE SYSTEMS
An IP surveillance system broadcasts their video as a digital stream over an IP network, such as a WAN, LAN, Internet or Intranet. IP cameras allow video and audio surveillance to be sent over a network using cat5 cable with an assigned IP address to each camera. This allows for a vast improvement over analog systems such as, extremely high megapixel resolution, individual camera configuration, wifi cameras, Power over Ethernet (POE), adding cameras from other networks, better security features such as people counting and facial detection. Some IP cameras can support resolutions of over 10 megapixels (3648 x 2752 pixels) and higher. This type of surveillance system allows for centralised management of your entire CCTV network. It also has remote accessibility to allow you to view live video & playback functionality for selected cameras via a mobile smartphone, computer or any other devices.
