IP Cameras
What is an IP camera? An IP camera is the evolution from analogue signal to a digital signal. IP cameras are based on the same networking technology used to connect computers (PC’s) to a network switch. The term IP camera is an acronym for Internet Protocol. IP cameras are also commonly referred to as HD cameras, High Definition cameras, Megapixel Cameras. Megapixel means millions of pixels. IP cameras achieve a higher resolution than analogue cameras. The more pixels in a picture allow for a sharper, clearer image MegaPixel Resolutions Number of Megapixels | Resolution | Aspect Ratio 0.3 Megapixel (Analogue) |  640×480 | 4:3 1 Megapixel | 1280×720 | 16:9 1.3 Megapixel | 1280×1024 | 5:4 2 Megapixel | 1920×1080 | 16:9 3 Megapixel | 2048×1536 | 4:3 4.1 Megapixel | 2560×1600 | 16:10 5.2 Megapixel | 2560×2048 | 5:4 8 Megapixel(4K) | 3296×2472 | 16:9 16 Megapixel(5K) | 4944×3280 | 3:2 30 Megapixel(7K) | 7360×4128 | 16:9 What is Aspect Ratio? Aspect ratio is the Vertical and the horizontal resolution of an image. The higher the pixels the bigger the image will be. High Definition TVs now broadcast in 16:9 aspect ratio where the older Standard Definition TVs used to broadcast in 4:3. Video Compression and how its affects image quality IP cameras run on a compression called H.264. H.264 is the evolution of Mpeg4 and allows for multiple Megapixel Cameras to record to a single NVR (Network Video Recorder) and run multiple cameras on a network without losing picture quality. H.264 profile works by only logging the changes in the P-frame and I-frame of images. The B-frame is completely ignored thus allowing for lower latency, lower bandwidth and increased recording space. H.264 can be as much as 60% more efficient over the previous Mpeg 4 codec. The next standard of video encoding will be H.265 or Hvec which will allow for encoding of higher resolution cameras i.e 8 Megapixel – 29 Megapixel at a lower bandwidth. How will IP cameras benefit me? Because IP cameras are based on a digital IP system this allows for higher image resolutions and clearer images. The installer can also access the camera directly and setup the camera from a PC in the control room. Most IP cameras can have an SD card slot where recording can take place on the camera, thus allowing for a failover of recording should the server be compromised. IP cameras that have audio can also record audio over a single cable. Installations can are also minimized due to IP Cameras only needing 1 cable for power, video streams, audio and any i/o switching. With the advent of High Definition cameras over Analogue Cable (HDTVI/HDCVI) it has allowed for entry level installation of HD cameras. The limitation of this technology is the highest resolution it can record is 2 Megapixel. All audio, power, I/O have to be run on separate cables. Example Of Analogue vs IP Below is an example of and IP camera and an Analogue camera. A Rotakin was used to test the cameras integrity. Both cameras were recorded at the exact same time looking at the same object. A two-megapixel IP camera was used with a 3-9mm lens with the lens set at widest setting. The Analogue camera had the exact same lens also set to widest setting at highest recording quality. Please note this testing was done in-house by CCTV Security Surveillance, all cameras are tested using the same.
Access Control
Access Control

  • Identification admission applications utilized for controlled access to restricted areas of entry
  • Time and Attendance
  • Provides accurate proof of employee attendance
  • Excellent for management of labor costs and payment reductions
  • Eliminates the risk of manual error
  • Fully compliant with SA Labour Regulations

Biometrics

  • Identification through set markers of individual biological traits utilizing fingerprint readers or facial recognition units
  • Biological markers cannot be duplicated or lost
  • Superior security access measure which eliminates theft and fraud
  • Suitable for Time Recording and/or Access Control

Proximity

  • Code-specific data verification linked to identity card access reader technology
  • Suitable for Time Recording and/or Access Control
  • Boom Gates and Vehicle Barriers
  • Monitors vehicle access to controlled entry and exit areas
  • Operates on horizontal and vertical pivotal positions
  • System technology utilizes infrared beams, coils or raised/lowered bollards

Turnstiles

  • Barrier arms restrict entry to one person at a time
  • Suitable for controlled pedestrian access or statistical data collection

Revolving Doors

  • This installation is suitable for controlling entry and exist pedestrian traffic flow in large buildings
  • The system supports energy efficiency and temperature control measurements

Man Traps or Air Locks

  • Installed with two sets of interlocking doors, operating independently of each other
  • Best suited for banks and high security buildings
  • The installation is also used to manage airflow restriction and temperature control

Spike Barriers

  • Comprised of embedded steel spikes which rise to prevent vehicle access
  • A popular security solution to manage traffic at casino and parking garages

Special Needs Gates

  • A user-friendly barrier designed to specific access and security specifications
  • Provides comfortable building access and assistance to people with special needs

Metal Detectors

  • Electronic detection systems installed in hand-held units or free-standing arched walk-ways
  • Suitable for high security access points in airports, banks, mines and restricted areas
Intercom Systems
CCTV offers a wide range of intercom systems from the standard one to one to the more advanced IP based intercom systems. Analogue intercom systems Analogue systems are basic point to point wiring; these intercoms are available in audio and video but are basic systems and cannot be upgraded to larger systems. IP Network audio and video intercom system IP network-based intercoms can be deployed into a client’s existing network infrastructure, this can result in a reduced deployment cost, and IP Intercom system can consist of multiple devices and can be up to 500 devices per master station. IP system can be integrated into building management systems and CCTV systems. GSM Intercom systems GSM units allow your mobile device to act as an intercom handset, the gate station will report directly to your mobile handset. This type of intercom system is much easier deployed into areas where cable routes are in-accessible, this unit allows up to 10 phone numbers per user and can be controlled from anywhere; this system allows up to 1000 users per master station.
Electric Fencing Systems
  • Installed as a restrictive electric barrier to produce an electric shock when touched
  • Specifically, utilized as a deterrent to prevent access to areas with perimeter boundary restrictions
  • Manufactured with predictable voltage control to comply with set standards of pre-determined danger levels
  • Energizers are comprised of solid-state circuits to improve longevity and ensure constant pulse width and voltage control
  • Fences emit high voltage pulse in intervals of time
  • It dumps the charge as soon as the conductive load touches the conductive wire.
  • Most fence energizers are hooked up to a permanent electrical circuit and put onto batteries or solar panels.

Uses for Electric Fencing Electric fencing is used to manage security and perimeter enclosure for commercial, industrial, manufacturing and agricultural sites. Agriculture:

  • Electric Fencing is very popular in agricultural areas. It is
  • Less expensive and faster to erect than conventional fencing
  • Animals are not restrained thereby risk of injury minimized
  • Notifications assigned to zone segments allow for ease of inspection

Wild Animals and Domestic Livestock:

  • Successful in controlling the movements of wild animals in close proximity to game resorts and private property within game reserves
  • Prevents domestic livestock from straying onto airport runways
  • Powerful deterrent to crop raiding

Security

  • Non-Lethal electric fencing for perimeter security to deter potential intruders
  • In the event of fence tampering sensor barriers activate a security alarm system
  • Strong physical barrier and psychological deterrent to intruders

Main types of electric fences Piggyback

  • Erected behind an existing wire or mesh fence.
  • Adds additional layer to existing perimeter security
  • Easy rivet or screw installation to existing posts of palisade fence pillars

Wall Top

  • Securely mounted on top of an existing wall
  • Recommended height is a minimum of 1.5 meters

Stand Alone

  • As a free-standing fence it works as the sole barrier
  • Installed primarily for high security areas or establishments
  • Minimum installation distance is 1 meter away from the closest barrier
