FAQ

What is the meaning of CCTV?

CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.
CCTV relies on strategic placement of cameras and private observation of the camera's input on monitors. The system is called "closed-circuit" because the cameras, monitors and/or video recorders communicate across a proprietary coaxial cable run or wireless communication link. Access to data transmissions is limited by design.
In the past, CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Modern CCTV displays can be high-resolution color, providing the CCTV administrator with the ability to zoom in on an image or track something (or someone). Talk CCTV allows the administrator to speak to people within range of the camera's associated speakers.

CCTV is commonly used for a variety of purposes, including:

  • Maintaining perimeter security.
  • Monitoring traffic.
  • Obtaining a visual record of human activity.

In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously, or only as required, to monitor a particular event.
A more advanced form of CCTV, utilizing digital video recorders  (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion-detection and email alerts).
More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network attached storage devices, or internal flash for completely stand-alone operation. Surveillance of the public using CCTV is particularly common in many areas around the world.

What is the difference between IP & Analog CCTV systems?

Video surveillance offers powerful, effective, and affordable security protection for both residential and commercial areas. Technological innovations have made video surveillance options easy to operate, customizable, and scalable tailored specifically for your purpose.

Initially, video surveillance employed analog technology, as CCTV or closed circuit television, recording video on videotapes. This method, however, had limited functions and was unable to transmit live information in real time.
Hence, it was not an efficient method of video surveillance when you needed information immediately. For example, when you monitor a storefront remotely, you need information on an ongoing basis instead of after the event. In addition, CCTV technology required manual transfer and changing of tapes regularly and did not offer great picture quality.

  • What is an analog video security system?
    Cameras on a modern analog CCTV system send their video in the traditional base band format over coax or UTP cabling back to a digital video recorder (DVR).
    Here, video is digitized and stored on hard drives. Most modern DVRs are a network device, and as such can be accessed remotely from the LAN, or with the proper configuration, from across a WAN or internet.
    There are no tapes to change and video is kept on hard drives, typically on a FIFO basis so there is always a rolling video archive of the past X days. So, despite the fact that video is being transmitted from the cameras in an analog format, live and recorded video is still available over the network.
  • What is an IP video security system?
    IP video cameras broadcast their video as a digital stream over an IP network. Like an analog system, video is recorded on hard drives, but since the video is an IP stream straight from the camera, there is more flexibility as to how and where that video is recorded.
    The DVR is replaced with an NVR (network video recorder), which in some cases is just a software since it doesn't need to convert analog to digital. Video footage can then be stored on new or existing network RAID drives as directed by the NVR software.
  • What is a Hybrid video security system?
    Hybrid CCTV systems combine IP and analog video, and can be a great way to transition an analog system to IP without needing to replace all of the existing cameras.
    Many NVR boxes on the market today, are actually Hybrids to suit analog cameras, and IP cameras and combine them into a single platform for the user.
  • Why Choose an Analog System?
    Cost. IP video security systems are generally more expensive.
    But, because the systems are designed differently from the ground up, there are situations where the cost difference between analog and IP is minimal, and even scenarios where IP video is cheaper.
  • Why Choose an IP System?
    Resolution. One of the biggest factors driving interest in IP video systems is the high resolution that it offers.
    Analog cameras max out on resolution at about 700 TVL which equates to roughly 0.5 mega pixels. High end IP cameras on the other hand are currently available at resolutions above 5 mega pixels.
    This high resolution gives users the ability to zoom in on video, and still have usable video.
    The other significant benefit to IP video is that it is compatible with wireless. Wireless analog systems are available, but they either have to convert to IP and broadcast over the 802.11 IP network (which adds cost for encoders), or they get crammed onto the over saturated regulated frequencies and often encounter interferences.
    IP-Based Video Surveillance Advantages:
    • Cost-Effective.
    • Easy Data Transfer and Storage, while digital surveillance can be transmitted over a LAN network. IP-based video surveillance enables easy transfer of digital information over TCP/IP networks, allowing remote monitoring worldwide. Data is easily stored on web servers and numerous forms of digital media for both convenience and long-term security.
    • Flexible Camera Placement.
    • You can easily hook your surveillance camera to any existing wireless network via an IP-based video surveillance system. Mount and position your camera onto your desired location. On the other hand, traditional analog video cameras are typically used in conjunction directly with a computer and needs to be placed within at least 10feet of the PC.
    • Easy Setup; simply plug in and play! Installing an IP-based video surveillance system is very simple. After you set up an IP address, you are good to go.
    • IP-based video surveillance systems are reliable and easy to upgrade. Since they are considered the wave of the future, you can keep adding to your existing system. On the other hand, CCTV and DVR hybrids are becoming outdated and are slowly being phased out.
  • Cost differences
    The cost differences between IP and analog can be significant, but that depends on the particulars of the design. Let’s break this down into some prime factors that will affect cost:
  • The Cameras
    IP Cameras are more expensive than analog. There are two reasons for that.
    First, an IP camera needs an internal encoder which adds to the manufacturing costs. To put things in perspective, an external encoder runs from $400 to $1000.
    Second, IP cameras don’t tend to come inclusive of outdoor housings or infrared emitters. If these settings are required, they have to be purchased and installed separately which drives up costs.
  • The Network
    IP cameras are constantly putting high bandwidth video data onto the network, especially if megapixel cameras are in use. Without the proper network speed and traffic control mechanisms, an IP video system can bring your network to its knees. Also, it is important to mention that each camera needs its own switch port, so extra switches needs to be accounted in the budget.
  • NVR vs. DVR
    DVR costs are fairly simple to understand. A DVR is a single unit, and is a one off cost. NVRs on the other hand are more complicated. NVR software is typically licensed only by one camera and must be installed on a PC.
    The storage requirements for megapixel cameras are significant, and may require additional network storage. When comparing costs, be sure to include the software, computer, and network storage in the total cost for the IP system’s NVR.
  • Cabling
    IP cameras use UTP cabling (at least 5), and analog cameras can use either coax or UTP (at least Cat3). In order to transmit analog video over UTP some inexpensive baluns are required, and coax cabling is slightly more expensive than UTP, so cabling cost for an analog system will be slightly higher.
  • Power
    Analog systems often involve a centralized power source for the cameras, and IP systems usually use Power over Ethernet (PoE). If the PoE switches are not already in place, they will be more expensive than the power supplies for the analog cameras.
  • Analog vs IP-Camera Video Surveillance
    Comparing Analog versus IP-Camera video surveillance features can help you choose the right option for you.

Analog or CCTV / DVR Video Surveillance

  • Easy to operate, similar to a VCR.
  • Poor Image Quality.
  • Analog recording resulting in lower quality of images.
  • Analog recording prevents easy searching and tracking.
  • Requires frequent change of cassettes and rewinding. This process is highly inefficient and can easily result in numerous errors. 
  • Storage tapes erode over time.
  • Storage is bulky.
  • Impractical to broadcast live images.
  • Only way to add DVR systems is via 16 channel blocks. 

IP-Camera Video Surveillance

  • Easy plug and play.
  • Higher Image Quality and adjustable frame rate.
  • Digital recording does not decrease recording quality over time, although playback.
  • Multiple camera operation and addition from one remote location.
  • High compression offers easy storage and transfer to numerous forms of media.
  • Instantly transmits images to any location in the world through remote or shared viewing via the web.
  • Easily encrypt digital images for security. Add updates and Extras with simple software upgrades.

Conclusion:

IP Video will always be more expensive, but the availability of much higher resolution recorded images makes it a much more powerful system. The ability to digitally zoom in on recorded video makes identification much more accurate.
