    CCTV System for Mong Kok Pedestrian Precinct

    Operational Guidelines


    On the afternoon of 13 December 2008, plastic bottles of acid were thrown

    from height and splashed in the Mong Kok Pedestrian Precinct (the Precinct) near

    the junction of Sai Yeung Choi Street South and Shantung Street, resulting in more

    than 40 injuries.

2. There have been precedent cases of objects thrown from height in the Precinct,

    a popular shopping area that attracts a continuous stream of visitors. For public

    safety reasons, the Yau Tsim Mong District Council (YTMDC) decided to install a

    24-hour closed circuit television (CCTV) monitoring system at the above location.

    The YTMDC Working Group on Mong Kok Pedestrian Precinct (the Working

    Group) was subsequently set up to follow up on the implementation of the CCTV



3. The purposes of installing the CCTV system are as follows:

    (a) to deter similar occurrences and restore public confidence in walking

    along the Precinct; and

    (b) to provide information to facilitate police investigation into similar

    occurrences in the future.

Installation Points

4. The Working Group has decided to install a CCTV system on each of the

    rooftops of Park-In Commercial Building (56 Dundas Street) and Hollywood Plaza

    (610 Nathan Road).

5. The above installation points are selected having regard to the following


    (a) the panoramic view from the rooftops of the two buildings can cover

    most of the area of Sai Yeung Choi Street South;

    (b) the property management company concerned has agreed to assist in the

    installation and operation of the CCTV system; and

    (c) the associated technical and logistical issues can be resolved through

    cost-effective means.

Installation of the CCTV System and the Mode of Operation

6. The contractor (the Contractor) of the Electrical and Mechanical Services

    Department (EMSD) shall be responsible for the installation, inspection, repairs and

    maintenance of the CCTV system, under EMSD’s supervision. The Contractor shall

    install and operate the CCTV system in accordance with the operational guidelines,

    take security measures as required by YTMDC to prevent stealing of the components

    and appropriation or leakage of information concerned, and be liable for breach of

    duty. The guidelines for the installation and operation of the CCTV system are set

    out below:

    (a) The number of cameras installed should be restricted to the minimum

    required to meet the purposes of monitoring throwing of objects from


    (b) Most of the area of Sai Yeung Choi Street South is covered by the CCTV

    system. However, the cameras must avoid direct projection into private

    areas including residential premises.

    (c) The Working Group will review the locations and perimeter view of the

    CCTV cameras regularly to ensure that the purposes of the scheme are

    met and that the cameras are operated in accordance with the operational


    (d) The CCTV system will operate automatically round-the-clock. The

    recorded images will be stored in a hard disk and automatically

    overwritten after 14 days. The Contractor shall safeguard against

    leakage of passwords used to protect the recorded images in the hard

    disk. The Contractor will be issued a written authorization jointly

    signed by YTMDC, Yau Tsim Mong District Office (YTMDO) and

    EMSD. The authorization letter should be produced to the security

    guards of the said buildings each time the staff of the Contractor conduct

    an inspection or repair of the system at their rooftops. The date and time

    of inspection and repairs shall also be recorded.

    (e) The Contractor shall deploy staff to the two buildings for regular

    inspection of the cameras and the CCTV system in order to ensure that

    they are functioning properly. YTMDO will also deploy staff to the said

    buildings to conduct regular inspections. In addition, the security staff

    of Park-In Commercial Building and Hollywood Plaza will help ensure

    the roof-top cameras are intact and functioning well during their daily

    inspections. If any irregularity is spotted, the security staff will inform

    the Contractor immediately for any necessary action. The CCTV

    system shall have an alarm device. Under normal circumstances, the

    alarm will be triggered when damages or defects are detected.

    (f) The Contractor shall, as far as practicable, prevent any malfunction of

    the CCTV system and ensure its normal operation round the clock.

    Upon receipt of a damage report, the Contractor shall address the

    problem on the spot within 24 hours and submit a report to EMSD and

    the Working Group within two days. EMSD should set out the

    procedures for the Contractor to follow in such cases.

    Moreover, the Contractor shall ensure that when power fails, the CCTV

    system will remain in normal operation for at least 30 minutes with an

    UPS. As the power will be connected to the essential power supply of the

    building, normal functioning should not be interrupted. (EMSD would

    draw up detailed operational guidelines in this respect)

    (g) If any hard disk component containing recorded images has to be

    discarded due to damage, termination of the scheme or any other reason,

    the Contractor must ensure that all information (including images) stored

    in the component has been completely erased to the effect that it

    becomes non-recoverable.

Posting of Notices

7. To ensure transparency of the scheme, notices in English and Chinese with

    symbols will be displayed in the area under coverage. A sample notice is given at

    Appendix I. Attention should be paid to the following:

    (a) notices should be placed around the buildings covered by the cameras so

    that the public are aware that they are entering a zone under CCTVs


    (b) the notices should be clearly visible, conspicuous, located in areas with

    adequate lighting, placed within normal sight range, and large enough so

    that the message can be easily read by passers-by; and

    (c) the notices should advise the public on means for making enquiries.

    Quality of Images

8. The quality of the recorded images should meet the schemes purposes and the

    following requirements:

    (a) the associated data recorded, such as the locations of the cameras and/or

    date and time, should be accurate;

    (b) the cameras should be regularly maintained to ensure that the quality of

    images meets the required standard; and

    (c) the cameras should be well-protected and maintained in good order.

Viewing and Processing of Images

9. The CCTV system has recording functions. The images so captured will be

    stored in the hard disk for 14 days and automatically erased thereafter. Proper care

    must be exercised in keeping and viewing the recorded images. The security

    measures are as follows:

    (a) the hard disk must be stored in a secure and locked cabinet designated by

    EMSD. The keys should be separately kept by the Contractor and


    (b) all movements of the recorded images must be clearly documented in a

    designated register. The Contractor should ensure proper recording of

    such information and safe custody of the register. The information will

    be subject to regular inspections by the Working Group;

    (c) the Contractor must ensure that no one is allowed to adjust or use the

    CCTV cameras at wish to obtain a view beyond the scope of coverage of

    the scheme;

    (d) the Contractor shall ensure that the recorded images are not viewed,

    downloaded, stored or copied by any unauthorized person. It must

    strictly observe the principles of confidentiality and bear the security

    responsibilities, as specified by EMSD in the contract.;

    (e) before any storage medium is discarded, all stored images should be

    completely erased to the effect that they become non-recoverable; and

    (f) EMSD shall monitor the performance of the Contractor to ensure that it

    acts in accordance with the rules and standards set out in the guidelines.
