Protecting property and family while helping to reduce crime in a residential area is easy and affordable with CCTV. Before installing a surveillance system, it is important to decide what kind of system best fits the needs of the property owners. Additionally, important to plan out the configuration of cameras and determine the type of cameras the situation calls for. It's also important to know how much lighting is available from the property and the general weather conditions of your hometown.
Benefits of Protection
A home that is equipped with a CCTV surveillance system is less likely to be broken into due to the discouraging sight of visible cameras mounted around the property. In the event that a burglary does take place, a CCTV system will record the break-in and provide clear evidence identifying a culprit, which greatly helps in obtaining an indictment and achieving justice. When a criminal is faced with overwhelming video evidence, they will often confess to the crime, saving the need for a trial and lawyers.
Analog Vs. IP-Based Systems
The type of system that should be installed should ideally be based on the needs of the property owners. If the video feeds are only to be viewed on site, then an analog system is sufficient. This is a set of DVR ports installed into an everyday personal computer or a DVR recorder unit set up in a central location. Either approach requires that wire feeds from each camera be run from the camera location through whatever path facilitates a clean signal to the motherboard in either a computer or a DVR. Images can be viewed using options within the surveillance software that will be running in either unit.
If remote viewing of live video feeds is necessary, then an IP-based system must be used. This is set up using a dedicated IP (Internet Provider) address that can be accessed remotely using a PC, Mac, iPhone, iPad or tablet. All video feeds go directly into the PC or DVR, which is then patched into a routing module with an active internet connection.
Configuring the Layout of Cameras
When setting up a home CCTV system, it is essential to determine the crucial areas that need monitoring such as entrances, walkways and large open areas. Each camera's line of sight should overlap that of other cameras on either side to assure there are no blind spots in the layout where a prowler could sneak through undetected. The larger a property, the more cameras will be required in order to establish 360-degree protection. Most CCTV systems consist of a network of anywhere from eight to sixteen cameras.
Selecting Camera Types
Available lighting, general location, and climate all play a part in deciding what cameras are best for certain areas in a surveillance system. A high traffic area is going to require a high-resolution camera with plenty of dynamic ranges and up to 30 FPS (frames per second) imaging ability. This allows many images to be captured in clear detail for accurate analysis.
A back gate-type of area with low lighting could require a bullet camera with an infrared feature that will record clear images even in the dark. A PTZ (pan tilt zoom) camera is useful for a position that faces a large area with lots of different possibilities of approach a burglar could choose.
Areas experiencing inclement weather will require cameras installed into weather-proof housing that contains heating and cooling elements to keep the electronics working during extreme temperatures. There are also cameras built into bullet proof and impact proof housing in the event that a robber attempts to disable a unit with a gunshot or the swing of a hammer.
Regardless of what cameras are needed, it is important to choose major brands with a solid reputation such as Sony, Panasonic or Geovision. An off name brand might be cheaper, but, in the long run, if the unit fails, the risk of being exposed is not worth the savings.
CCTV cameras, operating software, DVD recorders, and even coaxial cable to tie the system together can all be obtained inexpensively on eBay. Installing a system requires a bit of electronic know-how that essentially boils down to making sure each camera has an uninterrupted signal flow to the computer or DVR recorder. Another crucial concern is to assure that cameras are installed with quality hardware on a sturdy surface such as wood or supported metal. Neighbours could become inspired by a CCTV installation and decide to come up with a plan of their own, increasing the overall safety of the neighbourhood.
