Digital Security Camera Systems

When a person desires to buy digital security camera systems, either for home use or for a business, he will find a broad range of equipment, including CCTV video machines, CCTV lenses, video capture boards (with software) to use with computers, recorder systems (DVR), and other accessories. Also available is a range of digital video security camera packages to fit many needs. One thing to look for is the partnerships created between different types of electronics companies that will make available more systems that the buyer can use to fit into the specific needs at home or in the business. These partnerships will help fit more equipment into the intended use.

A digital video security camera can assist the owner in several ways. It can keep out unwanted people, even someone who desires to do harm. It can prevent accidents and give a visual trail of what happened during an accident. It can protect people and property and can help observe what's going on in the vicinity. Homeowners can use it to see who is at the door or even check on the house when they are not at home. Small business owners can keep track of shoplifters, burglars, and employees who are stealing from the business. Larger groups such as industries, research facilities, government buildings, or educational properties can be fitted with digital security camera systems to show any type of process going on in the vicinity. The basic components are a security camera, a display monitor, and a recorder. More complex technologies can also be added.

Available in digital security camera systems are either access control or sentry access control. Access control means restricting the entrance of a certain building or other structure to people who might want to enter. This could be physical access to a property, a building or to a room. The goal is to allow only authorized people to enter. In the past, the owner had to hire an entry guard or other person who could turn away unauthorized people or had to install locks and keys. These methods weren't always effective, and as modern society becomes more complex, less effective. But now with a digital video security camera, the same functions can be handled through technology. Keyless locks that had numerical push buttons allowed those who knew the right combination to gain entrance. The down side of this lock is that when the code needed to be changed, the entire lock had to be taken off the entrance and put back on when changed. This was a cumbersome process. On the other hand, digital security camera systems do not need to be disassembled to change the codes.

Another process that created systemic problems was the use of control cards and card readers. These readable devices allow people with cards to unlock the door by inserting the card into a reading device. Certain doors can be equipped to allow certain cards to enter and other doors to let other types of cards to enter. With this technology, the number of people using the process can be unlimited. The readers validate each person who wants to enter. Some of the more complex digital security camera systems use software to keep track of the card users. The software can monitor the activity through the doorway and keep a record of access both historically and real time. The software generates a log to keep track of access issues. These access controllers can come in single-door or multi-door versions. With more than one access point, the controllers can be connected in a network. That will allow all access problems to be configured and updated from a certain PC.

Another feature that can be built into a digital video security camera is an "anti passback" guard. That means that a person will be allowed to enter the building but not go back out. Most of the readers use radio frequency identification (RFI), which is much easier to use that the old swipe type of cards that used a magnetic stripe. The radio frequency identification only needs to be near the reader to register who is entering. Unlike the swiped IDs, the RFIs will not wear out or become damaged. They are also easy to duplicate. In places that need extra security, PIN numbers to be entered into a keypad can also accompany the RFI or biometric devices such as fingerprint readers or even retinal or facial scanners. The use of this technology means that a RFI can never be lent to someone who is not authorized to enter.

Knowing what is going on in private or business space is a definite plus in the world today. We all need to see what people are doing on our premises so that we can prepare ourselves to protect others and property. First Samuel 2:3 states, "Talk no more so exceeding proudly; let not arrogancy come out of your mouth: for the Lord is a God of knowledge, and by him actions are weighed." Using a digital video camera security system allows anyone to prove what has happened through taped incidents and not through arguments alone. That gives the homeowner or the business person the added advantage in a time of conflict or accident. And when access needs to be controlled, a digital video security camera can regulate the traffic twenty-four hours a day and assure the owner that the doors and other access points are securely managed.
