To make an informed decision about IP or Network Cameras, you first need to know what separates them from the standard analog cameras and why they are the better choice for your application.

To start with, going with an all IP based system can be simpler and more cost effective to install, as many offices already have existing network cable run throughout the building.  Analog cameras  require a contractor or installer to run coaxial CCTV cable through walls and ceilings.  Also, many IP cameras support Power  Over Ethernet so that you don't have to make a separate power run. 

Another huge bonus is that you can record the data from any networked computer. Analog cameras must be within about 1000 feet of the DVR or voltage drop can become a big problem. Since IP cameras are networked, they can be installed anywhere in the world and still be accessible to your NVR (network video recorder). This makes it possible to have cameras installed at your business while you record them at home, at a data center or anywhere else regardless of distance! Even if a break-in happens, you won’t need to worry about the vandals getting to the data and destroying it. You will have the information safely tucked away. This benefit alone makes an IP solution the perfect choice for anyone with a small business that can’t afford to have a break-in with nothing to show for it.

Expandability is also a key factor. Most NVRs can be easily upgraded via software updates, and new features can usually be purchased as modules. The number of available channels is usually sold on a license basis, so your system can expand easily.  Suppose you have, for example, a traditional 4-camera analog CCTV system using a 4-channel DVR. In order to upgrade to 8 cameras, you would have to scrap the DVR and purchase a new 8-channel DVR.  With a software-based system, you simply purchase an upgraded license to add the 4 extra cameras.  Additionally, most NVR systems can support up to 64 cameras or more, whereas traditional DVRs max out at 16.

Network NVR software typically has more powerful video analytics than a traditional DVR.  While stand-alone DVRs normally only support basic motion detection,  many NVR software packages will support more advanced analytics, such as counting, object detection, occlusions and more.  This is also coupled with a more advanced alert system.  Instead of just beeping like a traditional DVR, software can be programmed to send email alerts, SMS messages and much more.

Even if you already have an existing analog system, you can still start utilizing network cameras by upgrading to a 'hybrid' recorder. There are multiple options available in either a stand-alone DVR that can handle both IP and analog together or by using NVR software in combination with an analog capture card.  We have many solutions available so please consult your PolarisUSA sales representative today if you are considering making the leap forward to network video surveillance.
