Different Types of CCTV Systems
You can choose from three (3) different types of CCTV system when shopping for your CCTV system:
If you are looking for state of the art surveillance, go for Geovision PC based DVR cards. Sold in more than 80 countries, Geovision is the preferred digital surveillance solution of most security professionals for 2 main reasons:
- Geovision uses the latest high definition H.264 compression, which is only 1/4 the size of older MPEG 4 technologies. The smaller file size is very important for faster frame rate in video transmission especially if you would want to view your CCTV cameras remotely over TCPIP network or thru the internet from your desktop PC, laptop or mobile phone.
- Geovision software includes smart video analytics features such as face detection, people and object counting, missing and suspicious object detection, etc. In 2007, the Geovision won the FROST AND SULLIVAN AWARD for these innovations in digital recording. GeoVision's GV-Series is a PC based, multi-channel video surveillance system that utilizes the most advanced digital video compression technologies to bring you the highest picture quality and video performance. It is such a well designed, technically advanced but user friendly security solution that even prestigious institutions such as the FBI, NASA and US Coast Guard are using this product for security applications.
- Geovision is a hybrid surveillance solution. You can combine and integrate your previous investments in analog surveillance cameras with new IP-based surveillance cameras.
Up to 32 cameras can be connected and viewed live on a local monitor screen or thru TCP/IP network, internet, or mobile phone. Video can be recorded based on specified schedules or triggered by motion detection. Video clips are stored on your PC's HDD or any optical storage device by using GeoVision Backup System.
If you are looking for simple operation and non PC solution, go for standalone DVR's. A DVR is a security appliance that requires no special computer expertise and is ideal for non-PC-literate users. Every function on a standalone DVR is a matter of a push of a button which makes operation very simple. Standalone DVRs are also highly reliable and are very easy to use and install. They have all the basic features of PC based systems, and can also be accessed remotely through the internet or local area network.
Standalone DVR’s are in fact computer based machines which run Linux, Unix or other proprietary operating systems but the difference is that they are designed to run only one application (DVR Surveillance), which makes the standalone device a reliable appliance.
Our DVR models are sourced from manufacturers who are leaders in the industry and are backed up with full manufacturer's warranty, so you can expect from these units many years of reliable operation. Available are 4 channel, 8 channel, and 16 channel models.
If you are looking for cameras that can be directly attached to a network without a video recorder then go for IP cameras. An IP camera is a camera that has a built-in web server. It transmits video and control signals over the network. Video is viewed through a web browser or the software included with the IP camera and is recorded to the user's hard drive. Each IP camera attached to the network is given an IP address and can be remotely accessed over the internet.
IP cameras use newer technology than analog cameras and thus tend to be more expensive. However, since they already have a built-in web server and don't need a DVR, they can be an affordable solution for small sites.
