DVR System Guide
Our analog surveillance digital video recorders are available in three different models: Bronze, Gold, and Platinum and can use high resolution security cameras. The only difference between the systems is the resolution and framerate that they record footage at. Live view on all models is always full resolution. All models support various numbers of internal hard drives, each up to 3TB in size. Remote mobile access is available via iPhone and Android devices, as well as iPads and Android tablets. Free CMS software is provided to view your cameras on any PC or Mac system.
The consumer-class Bronze DVR records footage on channel 1 (or channels 1 and 9 in a 16-channel model) at D1 at 30fps and the remaining channels at CIF.
Business-class Gold recorders can record all of the channels at D1, but at 15fps.
Platinum enterprise-class surveillance systems record all channels at full D1 and at 30fps.
All analog surveillance recorders use standard CCTV security cameras connected to the recorder by coaxial cable with twist-on "BNC" connectors and powered by 12v DC power (some cameras do use 24v AC, but those are rarer).
Megapixel IP cameras use what is called a NVR, or Network Video Recorder, to record and store camera footage. When it comes to a NVR system, there are two different options to go with; and each one has their own advantages. Both allow remote access via iPhone and Android devices, as well as remote viewing from a PC. As IP cameras are measured in Megapixel resolution, you get up to four times the detail and clarity compared to an analog camera. The two different types of NVR are:
Standalone: A small NVR in an enclosure much like a traditional Analog CCTV digital video recorder. Much like analog systems, these come in pre-set configurations of four to sixteen cameras. The resolution and frame rate they record at depends on the number of cameras connected to the NVR, the fewer the cameras; the higher resolution and frame rate you can record at.
GeoVision: These are custom-designed NVR systems built from scratch to deliver the best surveillance performance possible with current technology. They support up to 32 cameras, and also provide the option to add analog cameras to the system with an additional DVR capture card.
HD-SDI is the latest in CCTV technology, using high definition security cameras with a digital picture over pro-grade coaxial cable. All HD-SDI cameras are 2 megapixel, giving you a true 1080p high definition image on all cameras. All HD-SDI digital video recorders include the ability to view your cameras remotely via mobile devices and tablets, and include free CMS software to view the cameras on a personal computer.
Due to its digital nature, HD-SDI CCTV cameras must use professional-grade coaxial cable and connect to the DVR system with a twist-on BNC connection. Most HD-SDI cameras can be powered with the same 12v DC power that current analog cameras utilize, making the upgrade to high definition CCTV a bit easier if you have an existing security system.
