Biometrics have changed the way we do security these days, with technologies like fingerprint recognition commonly used for access to high security areas such as those involved in high-level government security.
Although it's not the most popular biometric security method at present, facial recognition security is becoming more popular as facial recognition software and other technologies become both more affordable and more accurate.

Facial recognition security works by recording an individual's facial characteristics and then comparing the structure, distance between the eyes mouth and nose, and the general shape of the face based upon the locations and proportions of the cheekbones, nose and mouth, and eye sockets, and the outline of the jaw, all in relation to each other.
When facial recognition is to be used as part of a biometrics security undertaking, subjects allow several pictures of themselves to be taken, with different facial expressions and at different angles. For verification, subjects stand in front of the camera for a few seconds, and the resulting image is compared using facial recognition ...
... software to images that have been previously recorded. For greater security and so that masks cannot be used to try to fool the system, subjects may be asked to smile, blink or nod as they are verified, and/or facial thermograph may be used to measure facial heat.
This method of identification is accurate, and is becoming even more accurate as the hardware and software improves, and the technology is used by more and more people, and improvements are made
1. Facial recognitionsystems often require the person to smile or blink, or produce another human movement, in order to prevent against imposters who might wear a mould or mask from trying to gain access, or impersonate somebody else.
2. Official documents such as a passport or driving license can utilize face recognition technology, in order to prevent against all sorts of criminal activity stemming from the production and use of false documents. The use of multiple documents by the same person will also be reduced.
3. Facial recognition can be used for many other applications, such as authorizing transactions, perhaps instead of using a PIN number or signature.
4. Physical access can be granted or denied to a building, or department, using face recognition technology rather than by using a traditional access code, or swipe card.
5. Time and attendance systems are another obvious choice to use face recognition systems, as a way to combat people either clocking in or out early or late, or clocking in or out for an absent colleague.

Today's security systems utilize CCTV security cameras that utilize Internet protocol technologies. IP CCTV video security systems have better resolution than traditional analog systems do, more flexible installation, and easier to use features.
It can be expensive to completely replace old analog CCTV systems with new IP-based ones, but fortunately, you don't have to. You can integrate analog systems with new IP technology by utilizing a hybrid platform. This gives you all of the benefits of the newer technology and is a more cost effective option as compared to completely "starting over" with new equipment.
Whether you decide to completely replace your old analog CCTV systems with new completely IP-based CCTV systems or simply do integration of old and new technology, you'll find significant advantages:
In expensive, easy to set up and maintain
In Today, it's easy to buy and set up CCTV security cameras and related systems, and very easy to maintain, as well. Because today's CCTV security systems are digital in nature, they're much easier to manage. The information received from them is much more easily stored, and much less corruptible. Information is recorded on a DVR recorder with CCTV security cameras, instead of on tapes that can be easily damaged. You can also download the information from the recorder to a computer, and if you need to save the data long-term, you can burn it to a CD.
Continuous recording from all cameras
While older analog systems that used tape generally only did time lapse recording, newer CCTV security cameras can record continuously, and the information can be captured and saved from all cameras. This allows business owners, for example, to track data from all sources and to keep historical records; analog tapes, by contrast, were usually ultimately taped over, sometimes causing loss of valuable information.
Customizable
Because today's CCTV security systems and CCTV security cameras can be bought in an endless variety of configurations, sizes, and functions, you can choose your system based on your needs. In addition, as your business grows, it's easy to expand your system for more coverage as you need it. And because this technology is so inexpensive, you can grow your system as you need to, without the worries about expense, flexibility, or storage space traditional systems might give you.

Commercial Security Surveillance
Commercial security systems aren't anything new. But with new technological developments, there are more and more options for video surveillance systems at affordable prices. From encoded webcam systems to other Internet Protocol (IP) recording systems, there are a number of great surveillance options available for small businesses. Consider the benefits of video security for:
• Monitoring inventory
• Supervising staff to ensure appropriate employee behavior
• Providing security for parking lots
• Watching over the cash register
• Providing additional protection for staff
• Observe childcare staff
• Supervise child play from another room

• Monitor sleeping children
• Watch the house when you're away
3VR’s Dwell Time analysis reveals extraordinary new insights about the way individuals and groups behave in – and interact with – a particular environment
• Measure the performance of marketing displays with revolutionary insight into customer behavior as they interact with promotions
• Measure suppliers and end caps placed to promote merchandise within the retail or banking locations
• Add a visual dimension to business intelligence with location-based, hourly, daily, weekly and monthly analyses of actual customer behavior
• Integrate the Dwell Time analytic with POS data to evaluate the success of marketing campaign

SPECIFICATIONS
• Applications— Dwell Time can be located in overhead or side view locations where movement into and out of the location is clearly established
• Cameras — Analog or IP cameras. For IP cameras, video quality must be set to “highest” (if there is no video quality setting, set to lowest compression). Use wide dynamic range cameras for outdoor lighting situations.
• Lighting — Uniform lighting is ideal. Outdoor lighting situations should employ wide dynamic range cameras. Backlighting (bright conditions behind the car) will negatively affect performance.
• Mounting— Choose either vertical or horizontal mounting option:
o Vertical — Camera should be directly above the area to be monitored.

o Horizontal — Camera should be mounted at the same height as the subject being monitored.
o Diagonal (both at the side and above) mounting is not recommended.
o Field of View — For accurate recognition of objects in the field of view should be 30 pixels high or greater
