Choosing Two-Way Radios for Security Teams in Nigeria

Two-way radios are still the backbone of communication for security guards, estates, hotels, construction sites and events. They connect instantly, work without airtime, and keep a whole team on one channel. But radios are also one of the most misunderstood purchases. Range claims are rarely achieved, many radios sold under well-known brand names are copies, and the wrong frequency band can leave a team unable to talk across a single building.

This guide explains what actually matters when choosing radios for a team.

UHF or VHF?

Radios work on either UHF or VHF frequencies, and the choice depends on where they will be used.

• UHF works better inside and around buildings, because its shorter wavelength passes through doorways and around concrete more effectively. It suits hotels, offices, estates and multi-storey sites.
• VHF carries further over open ground with few obstructions, such as farms, large compounds and waterways.

All radios in a team must be on the same band. Dual-band radios such as the Baofeng UV-5R can use either, which helps when working with other teams.

Analogue or digital?

Analogue radios are simple, low-cost and compatible with almost everything. Digital radios, such as Motorola's MOTOTRBO range, offer clearer audio at the edge of coverage, longer battery life, and features such as GPS tracking, text messaging and private calls.

• The Motorola DP2400 is an entry-level digital radio with 16 channels.
• The DP4401 adds GPS, Bluetooth and IP57 protection.
