Police investigations can be hindered by the lack of, or poor quality of, CCTV evidence available.
A recent high value unlawful entry offence of a Sunshine Coast business served as another example of this. A CCTV system was in place but not operating due to lack of adequate maintenance.
A quality CCTV system not only provides a deterrent to offenders but also increases the likelihood of an offender being identified which may also aid in the successful prosecution of offenders in court.
A CCTV system becomes a powerful investigative tool for police when the recordings clearly depict events with sufficient detail to identify the person/s or vehicles involved.
Examples of desirable policing outcomes from a CCTV system include;
- the identification of a person's face at key points such as entries, exits, or sales counters
- the identification of vehicle licence plates
- the recognition of clothing
- the easy extraction or recorded video/images in a readily viewable format
The objective of a CCTV system can be identified by asking the question "What do we want to see?". CCTV cameras should be able to achieve sufficient resolution to meet this objective. Poor quality CCTV images are of little use to police or the business owner.
When seeking advice concerning the design, installation and maintenance of CCTV systems you should always use an appropriately licensed security professional.
