Benefits of Using Digital Video Surveillance Systems for Your Security Needs
The wave of the future in video surveillance is in digital video surveillance systems. In addition to the fight against terrorism, digital security systems installed in public spaces, buses, or retail centres can deter crime, the police to provide leads, helping citizens feel safer, and improvement of the economy of a crime-ridden area. This IP-based systems are not only accurate capture images, they do it in a way that is scalable within a company the current IP network with pan-tilt-zoom (PTZ) cameras and advanced rapidly.
This digital surveillance systems costing upwards of a million dollars because they are the digital surveillance cameras and the required connection to the IP-based network. Although the cost of these systems is much larger than traditional CCTV surveillance systems, the advantages of using Internet surveillance systems far outweigh their initial start-up costs and most company CCTV analogue systems are now gone digital for improved performance, surveillance camera maneuverability and fast user’s feedback.
How digital surveillance systems work
A digital security system consists of hardware and software components that collect and send the information by surveillance camera using wireless technologies, fiber optic cable or using an IP-based network. Both power and data can be run on the same cable using PoE (power over Ethernet). Some cameras in a digital system perhaps their own IP-address for full access to the Internet. These monitoring images are then transferred to a PC or laptop into a centralized control room are viewed by an observer using a compact, flat-screen monitor that multi-screen displays offers. An IP-based digital system is unlike the traditional closed CCTV-system, of which the images should be checked using multiple monitors, sites, and staff.
The digital system can control data on DVR (digital video recorders), some data can be saved on to 10 weeks-much more than analog CCTV systems save. After the DVR is back-up the images, they can be exported to disk using the CD-RW drive, and then they can be sent to remote PCs, laptops or handheld devices within moments over the network. Digital recording is 24/7, without the need for cumbersome CCTV video tapes that have limited storage capacity.
Key when you set your CCTV system replaces by a digital surveillance system
When a company or Government chooses to invest in digital surveillance systems, they need to pass the time in finding out how large an area must be viewed, and also of the situational parameters to invest. A digital system requires a major investment in front, but it is guaranteed to produce a positive ROI as the cameras are well placed and the images are constantly checked.
One of the reasons for the higher cost of the digital systems on CCTV is located in the high-tech cameras, who strongly the analogue CCTV cameras surpass. The cameras have functions ranging from solid models direction-checked or dome models with automatic pan, tilt and zoom functions that sharp images in the range of 1600 x 1200 pixel resolution. With the additional zooming and panning capabilities, a surveillance camera do the work of five, which is more efficient in the long run.
And at the highest end, there are cameras with an infrared capabilities to get movement and changes in light regardless of poor lighting conditions. Some even of this high-end cameras have 3D imaging better to suspects. Companies that invest in the digital system also consider camera accessories such as weather-proofing and added material that is resistant to manipulation and dangerous substances.
The successful use of an IP-based surveillance system
The Police Department in Newnan Georgia wanted a security system that can accurately capture images in public places, deliver, and archive later that images so they chose a digital security system. The Police Department are 22 cameras mounted on utility Poland property of Newnan Utilities and the surveillance software purchased from a local supplier, A-Plus Technologies. The officers browsed through the images via the Internet, where they can be picked up by the time, date, location and number of the camera. In a few months, the digital system helped officers in a drug bust and has also helped the police identify suspicious vehicles.
A promising future for IP-based surveillance systems
IP-based surveillance systems will show a lot of growth in the it and security sectors as they offer a scalable business-run solution that the advantages of flexibility and low cost of ownership. A digital system can be built within an already existing IP network will, and this fact budget Department of a company easier breathing.
Police services like in Georgia and other law enforcement agencies will also be interested in VCA (video content analysis) technology, which is much compares real-time and recorded images with a database, such as in the biometric technology. More likely to be apprehended Suspects and further crimes can be stopped when a digital camera picture of their faces are compared in a criminal database. VCA will also greatly increase the efficiency of the operators of the CCTV in their efforts to monitor and analyze an overwhelming amount of video content.
