The installation of security camera systems that meet the various standard specifications is crucial for any home, business or enterprise. Theft and crime are unwanted events that can be avoided with the help of advanced systems that help in detecting undesirables. The recorded and streamed images from these systems do not only help in protecting property but may also stand in as indisputable evidence. As such, fully functional security camera systems have become indispensable tools for many individuals who need to protect their material and property investments.
The Development of Security Camera Systems
The exponential growth and advancement of technology in the last few decades has paved way for better and more efficient security camera systems. While in the past, only high end properties could afford to have even the most primitive surveillance systems, modern times has shown a greater demand for up to date security camera systems. From government institutions, retail stores, schools, hospitals, hotels to private residences, these systems have now become more of a necessity than a privilege. With the development of wireless technologies, surveillance systems have evolved in scale and in design. One powerful modern design capitalizes on IP enabled systems. These types of security camera systems are integrated with the Internet, allowing for home and business owners to have a constant eye on their property wherever they may be.
Added features like live notifications at the moment when suspicious activity is detected allow for a tighter and more efficient security system. Some advanced systems are also installed with motion detection applications where the camera only begins recording and streaming the images when heat signatures generated by movement activate the special sensors. This added functionality is heralded as one of the most cost and energy efficient solutions when it comes to security camera systems.
There are also some designs out there that offer smart and individualized solutions. Some have individual cameras installed with their very own memory units apart from the centralized memory unit in the computer. These are considered to be the most current advancement, referred to as digital surveillance systems. This design allows for a much bigger capacity for recording and the images are automatically optimized and stored. These types of security camera systems have even rendered the video tape recording obsolete.
Digital System Components
When installing security camera systems, consumers should be aware of some key functions that can make a world of difference. Bad or a substandard set of features could negatively affect image and video quality, storage capacity and other key areas. Today, almost all of the leading brands in surveillance systems now put their research and development into fine tuning and improving digital camera systems. Here are some standard components that go with these modern security camera systems.
The Digital Camera
Most modern digital systems can function as component systems. This means the camera unit component of a system can be compatible with another part of the system regardless of the developer and manufacturer. This versatility in security camera systems allows for a custom tailored design that can be made to suit the owner's specific needs. Generally, cameras can vary in the following functionalities. Some specifications are made for either indoor or outdoor use. Some cameras can go for both types of environments.
Digital systems now make use of wireless technology, this modern technology means that systems no longer rely on bulky transmission cables. Digital camera systems are also built with light sensitivity adjustment features. With this, quality images can still be produced even in dark and low light environments. Some modern types are also built with infrared technology for clear night vision recording.
Motion Sensors for conditional activation help in lowering energy cost. Most cameras now also come with rechargeable batteries which combined with wireless technology and memory units, make for a fully individualized security camera systems. Built with Internet protocol allowing for Internet networking and connectivity covert or disguised designs allow for the digital camera to easily blend in with the environment making them less noticeable from intruders. Some can even be disguised as part of the interior decoration. Modern security camera systems are also built with units that can easily track movement in the environment with (PTZ) or pan-tilt-zoom functions.
DVR and Processing
The processing unit or the DVR is considered as the brain. This central unit receives the signals sent from the camera units and processes the video and images with CODEC (compression and decompression) utilities to render the files. The DVR may also facilitate other key features within the system such as the motion detection aspect as well as PTZ control for specific units. This unit also serves as the main storage unit in security camera systems. Processed video and images are stored and can be retrieved for later use. The camera load for each processor varies. Some have only 4 camera units while moderately sized ones can have as much as 16 units. This is typically used for business and retail environments. The CODEC utilities determine the video file format. Some systems are built with multiple utilities like MOV and MPG1.
Modern central units are now built with large capacities in storage space. Some offer hundreds of Gigabytes while other security camera systems offer Terabytes of digital storage. Digital systems usually come with DVRs that have expansion slots and bays. These can add various functionalities apart from the basic processing task. Some common added hardware features for the DVR of security camera systems include slots for Flash Drives and Disc Writers. These are crucial features as such features can help in providing key evidence in disputes. For residential environments, converting and utilizing the home personal computer as the processing unit for small scale security camera systems is possible. Most systems provide a PCI card for the computer. With this, driving down the potential costs for security camera systems is feasible.
With the constant threat of crime and theft, having security camera systems can potentially be a home and business owner's best investment. Knowing all the standard features as well as some crucial upgrades and added functionalities helps immensely in ensuring that you get the best surveillance system to protect yourself, your family, and your business.
