Outline of the Assignment 9 Requirement

You are to produce a conceptual design for a new CCTV system for a gated community of luxury villas in the template provided at the end of the task description.

The Crest is a luxury development of villas set on a hillside in the Portuguese Algarve. It is a gated community with a guard on site. Further details can be found at

A slide set of The Crest will be sent to you under separate cover.

Please note: Do not contact the site management for further information. If you need additional information, ask ISMI.

Your task for this assignment is in two parts. It is recommend that you undertake the two parts in parallel, but only after a complete read-through of the unit textbook. Unit 9 is technical, so you may need to read it more than once and ask for coaching to explain the more complex technical concepts.

Task – Part 1

You have been asked to put together an outline concept for a CCTV system to replace the existing very basic system.

You are required to do this using the text provided in the unit textbook and the supporting documents. Specifically, following to the extent possible the format of the template provided in the HOSDB CCTV Operational Requirement (Extranet Library), produce an operational requirement for the site.

Your concept should be supported by plan drawings (these may be good hand sketches or computer-drawn), and should take into consideration:

  1. Camera type and selection(eg. number, analogue, digital, fixed, PTZ, cube, bullet, box, dome, colour, monochrome, normal resolution, megapixel etc.)
  2. Camera configuration(eg. field of view, angle of view, focal length, resolution, frame rate etc.)
  3. Privacy.
  4. Site landscaping conditions(eg. there are many trees so these will affect camera placement).
  5. Illumination(eg. How to deliver good image quality with the site illumination already provided).
  6. Masts(eg. Location, height, direction or PTZ head etc.)
  7. Transmission(eg. local to site hub and then on to remote monitoring centre in Faro (see part 2 below).
  8. Storage(eg. DVR, NVR, on-site, off-site, capacity etc. Be sure that your storage capacity is adequate for your system. Clues to this are in Part 2).
  9. Monitoring(assume off-site).

Task – Part 2[Use the template provided further below to answer these questions]

In parallel, you are required to address the following points:

  1. You need to make a decision between an analogue-based system and a fully IP digital system. Using the reference material, carry out a comparative analysis of each, considering overall the relative merits of cameras, transmission and storage.
  2. There is a concern about vehicles tailgating through the automatic gates at the main entrance. On the old system there have been cases where the fixed camera has missed vehicles entering. What might have been the problem and how can it be addressed?
  3. In the old system, although the storage had been updated to a RAID system the guard complained that while the live images were of good quality, when they were played back the image detail was often too indistinct to be of any real value. What might have been the problem and how can it be addressed?
  4. You need to present a strong business case for the upgrade. On a facility such as this, what are the added-value (non-security) benefits of such a system?
  5. The budget will extend to 20 cameras. You would like to set the recording resolution at 4CIF and the frame rate as 10 fps, but with provision for two cameras recording at 1 fps. You intend to keep recordings for a minimum of 14 days. The video will be encoded using H.264. What size storage do you require? (You can send in draft answers for checking).
  6. At times the local videoconsole may not be manned and you intend to transmit your images to a site in Faro, some 6 km away, line of site. The transmission options you are considering are:
  7. Microwave.
  8. Internet.
  9. Dedicated fibre optic.
  10. Leased line.

Carry out a comparative analysis of each option.

  1. You have a requirement to provide identification-quality video of intruders in an area of the site where illumination in the visual light spectrum is undesirable. The camera will be located approximately 20m from what is assessed to be the most vulnerable point. You have been asked to evaluate the feasibility of both IR-assisted cameras and thermal imaging cameras. What would be your response?
  2. Explain how you will address the privacy concerns of the residents. Most residents have stated that they don’t want cameras to be able to view beyond their personal perimeter boundaries. Specifically, their pools should be out of field of view of cameras, as should any window above ground floor level.
  3. Explain how you can add value to this installation through the application of video analytics and intelligent video.
