In any country, the issue of law enforcement is a vital issue, and for that reason, police and detective departments have hurried on to install new and improved varieties of police scanners. Choosing the best police scanner can be a difficult task, but there are many online portals which are reliable for buying the scanners, or getting feedback about how to buy the best police scanners.

What exactly is the police scanner?

Primarily it is important to understand what exactly a police scanner is. It is mandatory for the law enforcement branch and the police or the detective department, to decode and decipher secret messages, code words and numerical database through calls. Sometimes, the calls have an underlying meaning of threat and terrorism, and if the code words or messages are not displayed and deciphered correctly, then the security of a country can be at stake.

There are some salient features of the police scanner. They can be listed as below:

  • To understand the message within a particular location or to decipher a particular message within twenty four hour time, a police can take the help of a scanner.
  • In case of address verification and detection, the scanner also records the repeated calls at a stretch.
  • Almost all the police vehicles at the present time are equipped with MDTs or Mobile Data Terminals. These terminals can partially at least try to detect all those part of the messages which are sent to the box or screen.

Why the knowledge of trunking frequency is important in a police scanner?

There are separate trunking frequencies for both analog and digital police scanners. For example, in the Portland area public safety department, the analog trunking system is very popular for the scanners. The base frequencies can be something like the following:

  • 854.5875
  • 856.4625
  • 851.2875
  • 857.7375
  • 858.4375 And many more. The frequencies may vary from one area to another. For instance, as the directions vary from North, South, to East and South west, the frequencies can differ and the scanners can operate accordingly.

The talk-groups as a case study:

There are different talk groups which can act as a case study for the police scanners. For example, in Oregon, the fire groups, the public safety agencies, the police patrol, detective and investigation agencies, reserve police units, police unit officers and explorer scouts are some of the groups which make use of the police scanners.

There are tactical channels and dispatch channels which help in understanding and deciphering the meaning of codes through the scanners. There are specific acronyms which are used by different agencies. For instance, the websites provides very important information regarding the four digit number identifications, the wave frequencies, and the particular talk groups and enforcement agencies, which can operate their groups and official works with the help of these scanners.

One or two of these include:

  • DUII: driving under the influence of intoxicants.
  • FIR: field interview report.
  • JDH: juvenile detention home.
