Guide to Closed Circuit TV (CCTV)

A Collection of Covert Considerations - continued

Based on experience, Doktor Jon would recommend that if CCTV material is ever intended to be used as part of a criminal investigation or court evidence, a complete twenty four hour
period should always be recorded, and not simply the ten minute segment showing the suspect committing an offence.

This in itself, would not prove beyond reasonable doubt, that any other individuals were involved as well, and that due to technical limitations or incorrect set-up, the system had failed to ‘capture' any additional persons involved in the crime, or simply those other innocent 'passers by' present around that time.

Once the cameras are hidden and the transmission system is all set up, you need to make absolutely sure that the most appropriate video record system is going to be used.

To find out about all the various options and techniques, Doktor Jon will guide you ever so gently through all the ins and outs of producing Evidential Quality Recordings.

It's important to remember that as digital recording is currently developing at such a rapid rate, some of the established analogue units may start to be withdrawn from use in the very near future.

First things first; if the application is based on a portable bag or briefcase type setup, their are a limited number of very small tape based analogue, and hard disc digital recorders that would
fit the bill.

Apart from the obviously important aspect of small physical size and weight. these recording devices will need to
run from a low voltage, compact battery derived power supply, to achieve maximum portability.

The tape based systems may use VHS, or 8mm as the recording medium, with a typical resolution of around 250 horizontal lines.
