KEEP AN EYE ON YOUR BUSINESS

CCTV

As Businesses start to realise the many advantages of a CCTV System and the numerous benefits of this system, the demand for CCTV grows. With feature rich systems, at affordable prices for Small, Medium and Large Businesses.
Whether you are looking to monitor indoor or outdoor, a CCTV camera is available for just about anywhere you need to keep an eye on.
When taking into consideration that you can’t always be everywhere, and that guarding is a costly monthly expense, CCTV makes financial sense. CCTV plays a crucial role in your efforts to make your employees feel safer, keep an eye on your business assets and property, and criminal activity detection around the clock. Various studies have also shown, that where CCTV systems are installed, there is a reduction in criminal activity.

IP Cameras

IP stands for Internet Protocol. This means that a Digital Video Camera can send and receive data via a computer network, as opposed to sending a feed to a Digital Video Recorder (DVR). This is advantageous for a lot of reasons:

  • Picture Quality: The best analogue surveillance camera is still not as good as an entry level IP camera when compared to the resolution of the image it captures. An analogue camera can manage the equivalent of less than half a megapixel. Many of the Hikvision cameras we install are available in 2, 3, 4, 5, 6, and 12mp configurations, which is far better quality than you could hope to achieve with a traditional CCTV camera. IP cameras capture a much wider field of view than comparable analogue cameras, meaning a single IP camera is potentially able to do the job of two to three of the old school cams.
  • Video Analytics: This is a fancy term that basically means you can set your network to flag “events” that occur in the cameras’ field of vision. This could be anything from motion detection to missing objects to tampering with the camera itself. Instead of working through hours of footage, your network can tell you exactly when these events occurred and point you right to them.
  • Flexibility and Scalability: In a traditional analogue DVR set-up, each camera must be connected directly to the DVR. IP cameras can circumvent this through the use of switches, which allow cameras in close proximity to each other to be connected to a single switch, which then runs a single wire to the NVR (Network Video Recorder). This reduces the number of cabling runs, which makes it ultimately less labour intensive, and also allows you to connect more cameras because you’re no longer limited by the number of ports on your DVR. On top of that, using a PoE (Power over Ethernet) switch allows your Cat 5e or Cat 6 cable to run the signal AND provide power to your camera, eliminating the need for a separate power supply.

IP Cameras come in wide selection of form factors. IE: Bullet, Box, Fish Eye, PTZ etc. With various lens configurations, and a whole heap of settings to customize your installation.

Analogue Cameras

Analogue cameras transfer the video signals in analogue form (electrical signals)
Analogue cameras usually use coaxial cables for the cabling and have the videos recorded by a DVR (Digital Video Recorder), where every single camera is directly connected to the DVR. Below are some of the advantages of an analogue system.

  • Cost: The most obvious reason to install an analogue system is the price tag. Analogue cameras tend to be more cost-effective than their IP counterparts (though IP cameras have become very cost effective). This is a factor to consider when deploying a lot of cameras.
  • Installation: The ease of setup on a DVR (Analogue Recorder) is easier than on an NVR (Network Recorder)
  • Technology is getting better: High definition (HD) analogue has increased the picture quality and the resolution, you can get four- and five-megapixel cameras that are HD analogue, and that’s impressive.

NVR & DVR

DVR (Digital Video Recorders) and NVR (Network Video Recorders) come in various models and types. Understanding what to look for is important and even more important is understanding what you need. Typically NVR’s and DVR’s are available in the following form factors: 4, 8, 16 and 32 channel (camera) systems.
Even if you have 6 cameras, choosing a form factor of 8 or 16 allows room for potential growth of your camera system
NVR vs DVR: The difference between an NVR and DVR can be confusing to many. A network video recorder (NVR) records IP cameras that are transmitted via a network cable. These cameras connect to an NVR either by way of a network switch or router. In essence, NVRs record IP Cameras. Digital video recorders (DVRs) are synonymous with recording analogue or coax-based cameras. They both record cameras and offer the same similar options but they record different transmission methods.


Ease of use: Both NVRs and DVRs offer very easy menus to navigate and program the recorders. NVRs tend to be slightly more difficult because the cameras themselves are network devices so they must be programmed with an IP address just like any other device connected to a network. The NVR itself recognizes the cameras and sets them up for you. This makes using IP cameras a lot easier. DVRs are more cut and dry. Cameras do not need to be programmed or set up when connected to the recorder. They are a simple plug and play solution. Both systems offer remote video monitoring and HD recording capability.
Storage Size: With most NVR and DVR’s, you have a choice of the size of Hard Disc Drive that can be fitted for storage. Storage is determined by a number of factors like, how long the recordings need to be kept, resolution at which recordings are made, etc.
