Protect your Business with the Right Solution

The days of expensive time lapse VCR's, multiplexers, splitters and monitors are numbered. Today, this expensive and performance-limited equipment is replaced by computer technology resulting in better recording quality, control and functionality as well as remote viewing. All these enhanced features are often available for a lower price and lower total cost of ownership. Therefore, video security is becoming more widespread everyday as a means of keeping track of employees, locations, entryways, and more.

Originally designed to monitor safety concerns, video security is continually evolving making it the ideal solution for many types of businesses and home uses. Businesses use video security systems to monitor employees, to trigger alerts in case of fire or motion, and to watch over entrances to buildings. Video security is also used in retail stores to reduce shoplifting and in financial institutions and convenience stores as a deterrent to robbery. Parking lots and garages, remote areas on college/university campuses, and hospitals are also popular locations for video security systems.

"Why Digital Video Security?"

There are four basic reasons why people want to use a digital video security system:

  • To help IDENTIFY perpetrators
  • To help PREVENT accidents or wrongdoing
  • To help PROTECT people and property
  • To help OBSERVE processes

"Who can benefit from a Video Security System?"

All these things and many more are possible through video security systems.

  • Small Businesses can prevent or identify shoplifters or burglars and keep an eye on the business from home. Sadly, today, employee theft is now higher in retail than customer theft and monitoring retail employees is becoming necessary.
  • Industry & Research can monitor processes as well as maintaining security surveillance.
  • Education and Government can keep an eye on trouble spots.

"What do I need?"

The basic components of video security systems are a security camera, a display monitor, and a recorder. In a large system, of course, there can be a number of security cameras with multiplexers, time lapse VCR's and monitors. Today, however, much of this analog multiplexing and tape recording equipment has been replaced by digital video recorders (DVR's).

A complete state-of-the-art digital video security system will include quality CCD cameras connected to a digital video recorder system. This setup allows for password-protected viewing of live and recorded video at the DVR and/or from a PC or PDA connected to the Internet or to a LAN.

Such a video security system as described above can mean a significant improvement in loss prevention and safety control for businesses and in peace of mind for home owners.

  • Record days to months of video
  • Watch video remotely from anywhere in the world
  • Virtually unlimited number of cameras and locations at the same time

What kind of camera should you choose?

Cameras come in different shapes and sizes. Know that this in itself does not affect the picture quality. The shape rather should be looked at in terms of cosmetics, convenience of installation and camera placement. Two cameras with different housings and similar components should perform no different if constructed properly.

  1. Dome
  2. Box
  3. Infrared
  4. Bullet
  5. Covert/Hidden
  6. PTZ (Pan, Tilt, Zoom)

PC based system vs non PC based

One of the most frequently asked questions about DVR's is: Which is better a PC-Based or Non PC-Based DVR solution? There isn't much that a non-PC based DVR solution cannot do today, which a PC-Based DVR can. The difference has more to do with the "footprint". PC interfaces tend to be more user-friendly and less "mechanical."


PC-Based DVR's tend to be more flexible and easier to manage. PC-Based solutions also tend to allow for upgrades of compression technology, which can be vital to the end user. Remember, in the IT world, you blink and they are onto the next technology.

Non-PC-based solutions tend to use "ASIC" (Application Specific Integrated Circuits) technology, which does not allow for upgrading of a technology platform, similar to your microwave oven. ASIC, is a chip that is custom designed for a specific application rather than a general-purpose, such as a microprocessor. ASIC, unlike an FPGA, has fixed functionality and is not re-programmable.

In the PC environment, the latest technology utilizes DSP's (digital signal processors). A DSP is a specialized digital microprocessor used to efficiently and rapidly perform calculations on digitized signals that were originally analog in form, such as audio and video. The big advantage of DSP lies in the programmability of the processor, allowing parameters to be easily changed.

Image Resolution

Image resolution describes the detail an image holds. The term applies equally to digital images, film images, and other types of images. Higher resolution means more image detail.

Birate CIF (Common Intermediate Format) is used to standardize the horizontal and vertical resolutions in pixels of YCbCr sequences in video signals. A CIF is commonly defined as one-quarter of the 'full' resolution of the video system it is intended for (listed below as 4CIF). Note that this full resolution does not match what is currently referred to as D1 video (based upon Sony's D1 format).

Video resolutions (in pixels) x NTSC-based x PAL-based CIF (NTSC 352 × 240) - (PAL 352 × 288) 4CIF (NTSC 704 × 480) - (PAL 704 × 576) D1 (NTSC 720 × 480) - (PAL 720 × 576)

Video Storage (How many days of video can you store?)

Ultimately, in order to accurately determine how much hard drive space you will need with your DVR you need to take into consideration the codec technology being implemented, image resolution size, the bit-rate/compression ratio, the amount of video activity, is the bitrate variable or constant, and if motion detection (setting the DVR to only record activity when the camera detects motion in its field of view) is being utilized. Next, calculate the number of cameras and how many frames per second you want to record on each.

Advanced DVR systems, will allow you to independently control each channel for:

  • Image resolution
  • Bit rate (constant/variable)
  • Display frame rate
  • Record frame rate
  • Motion detection

The size of a file of video data can be affected by image size (resolution), bitrate, motion, compression and various other factors, as previously discussed. Ultimately this can affect the amount of video you will be able to store on the DVR's hard drive and overall performance when viewing and recording multiple cameras simultaneously.

As a rule, the higher the compression ratio, the smaller the file size. The smaller the file, the less sharp the image, the quicker the transmission speed, the less storage space and processing power required. Conversely, a lower compression ratio results in a larger file size, sharper image with a slower transmission speed and more storage space and processing power required.

Compression Technology (MPEG-2, MPEG-4, H.264)

Compared to prior generations of MPEG-4 and MPEG-2 technologies, H.264/AVC video quality and performance is significantly better. Even with its higher quality video the H.264/AVC file packet size is at least 25% smaller than MPEG-4 and 50% smaller than MPEG-2, requires significantly less bandwidth and offers rapid download times. Unlike the earlier MPEG technologies, H.264/AVC is capable of stabilizing images.

In contrast with 11-year-old MPEG-2 and 7-year-old MPEG-4 standards which were developed for TV and entertainment, the H.264 codec was designed with commercial security as one of its applications in mind.

CCTV Video Surveillance Security Camera System

Though most of our attention these days is focused on the transition to IP video technology, it's important to note that analog CCTV security cameras can still be highly effective for many surveillance applications, especially those on a budget. With traditional CCTV security cameras, the video signal is processed and transmitted in analog format for local viewing from one central monitoring location. But that doesn't mean you can't use analog cameras in an IP-based surveillance environment. Using IP video encoders and other equipment such as digital video recorders and hybrid DVRs makes it possible to leverage your existing analog cameras while migrating into the world of digital surveillance.

What is a CCTV security camera?

In its truest form, a CCTV camera is an analog video camera that transmits signals via coaxial cable to a single central location for monitoring, recording, and video analysis. While the recent trend is a push towards IP network cameras, CCTV cameras are still widely used, and offer a cost-effective answer to many common surveillance scenarios.

CCTV technology has been around since the 1940's, and became a major player in the security industry around 1970. The technology is tried and true, and there are CCTV security camera models for virtually any surveillance application. The two main categories of CCTV cameras are fixed cameras and pan/tilt/zoom models which can rotate horizontally and vertically to cover more area.

Pros and Cons of Analog Surveillance

These days, there's a lot to think about when putting together a video surveillance system. And the first question on most people's minds is “Do I go with traditional analog cameras, or IP network cameras?” There are pros and cons to both choices. Let's focus our attention on analog CCTV surveillance cameras.

Pros of analog CCTV

Lower initial cost - In most cases, analog cameras cost less up front than IP network cameras. Wide-spread compatibility - Mixing and matching camera models and surveillance equipment form different manufacturers is easy with an analog CCTV security camera. Lower initial cost - Analog cameras tend to handle low-light situations better than IP cameras on average, though IP camera technology is improving in this regard.

Cons of analog CCTV

Expensive cabling - For large-scale surveillance applications, analog cameras require complicated cabling schemes that can be quite expensive and also challenging to install. Limited features - Many of the advanced features now available with IP cameras (for instance: megapixel resolution, digital zoom, and video analytics), aren't available in analog CCTV models.

Components of a CCTV Video Surveillance System

There's a lot that goes into a typical CCTV video surveillance system. While the cameras get most of the attention in the beginning, you also have other concerns, such as viewing, recording, and archiving the video footage, and the equipment required for carrying out those tasks. Here's a look at the basic components of a typical CCTV system.

Cameras

Security cameras are the starting point for most CCTV video surveillance systems. There are endless possibilities when choosing CCTV cameras and lenses – everything from fixed models designed for monitoring very specific locations, to day/night cameras, and powerful PTZ domes for patrolling large areas.

Monitor

In a traditional CCTV security camera setup, operators view footage from a central location on a monitor very much like a TV, but with higher lines of resolution for better picture quality. Monitors can be dedicated (meaning they display video from a single camera), or call-up (meaning operators can access multiple cameras at the same time).

Cable

With an analog system, coaxial cable is required for transmitting video footage from the CCTV security cameras. This is one of the drawbacks of analog CCTV video surveillance, as the cable can be expensive and difficult to install, especially for larger camera networks, and those were cameras must be positioned in difficult locations.

DVR

Most modern CCTV video surveillance systems incorporate DVRs (digital video recorders) which enable operators to reap some of the benefits of a network-based surveillance setup. DVRs convert the analog footage to digital, which helps to extend storage capacity, makes it much easier to search archived footage, and also allows users to stream video over a network for remote viewing from multiple locations.

CCTV Security Camera Types

Fixed CCTV surveillance cameras

Fixed security cameras point in a single direction, which makes them perfect for monitoring very specific areas of interest. They're also preferred for applications where it's beneficial to install cameras in clearly visible locations. For this reason, fixed CCTV surveillance cameras are quite effective not only for capturing footage of suspicious activity, but also for deterring criminals and vandals from carrying out their acts in the first place. The direction of the camera is set during installation. Many security cameras also accept interchangeable lenses and housings, so you have the flexibility to meet a wide variety of surveillance needs.

PTZ

PTZ cameras are ideal for wide-area surveillance. They give operators the ability to remotely control pan, tilt, and zoom functions to follow activity and to zoom in for detailed monitoring. This is an area where analog CCTV security cameras fall behind their IP camera counterparts. With IP cameras, the pan/tilt/zoom functions are controlled manually or automatically and delivered over a single network cable, while analog cameras require additional wiring to perform similar functionality.

Measuring CCTV Image Quality

Understanding TVL Resolution

The image detail of an analog CCTV surveillance camera is usually conveyed in a form of measurement called TVL (or TV Lines). Think of the video picture as being composed of active horizontal lines. These lines are delivered to a monitor or recording device in two off-set fields. One field contains even-numbered lines while the other contains odd-numbered lines. The viewer sees a complete picture because the lines are interlaced. Since the picture has a 3x4 aspect ratio, the amount of detail you can measure in 3/4 of the picture's width determines the horizontal TVL resolution. Generally, most standard CCTV cameras offer a TVL resolution of around 380, while high-resolution cameras will deliver something closer to 540 TVL.

Effects of Digital Conversion on Image Quality

Most analog CCTV systems today use a DVR as the recording medium. This allows the analog signals to be digitized for recording and for delivery over the network. While a DVR solution is a cost-effective alternative to IP video, and provides users with valuable benefits such as digital storage and remote accessibility, there are drawbacks. One is a slight drop-off in image quality. Simply put, it's harder to retain image quality in this type of setup because of the various analog-to-digital conversions that take place from the camera to the recorder. Cabling distance also plays a role, as the further the video signals travel, the weaker they become. Still, a DVR-based solution is a very good option for users looking to reap some of the benefits of digital IP surveillance while using lower-cost CCTV security cameras.
