What types of radios are best for security work?

For professional security use, we recommend digital UHF radios or PoC (Push-to-Talk over Cellular) devices. These offer clear audio in noisy environments, encrypted channels, and reliable coverage across large buildings, sites, or venues.

Should I use licensed or license-free radios for security?

For most commercial security operations, licensed UHF radios provide better range, privacy, and reduced interference. We can assist with RSM licensing in NZ. For small-scale or informal use, PRS radios may be sufficient

Are your radios discreet and lightweight for use during events?

Yes. We offer slim, lightweight radios that can be clipped to belts or worn under clothing, with options for covert earpieces and remote PTT microphones for discreet communication.

Can your systems support multiple teams or zones?

Absolutely. Our radios support multiple channels and group calls, making it easy to divide communication between entry control, patrol, response, and command teams.

Do you offer radios with encryption or secure communication?

Yes—many of our digital and PoC radios support voice encryption and secure channel access, ideal for operations requiring confidentiality and data protection.

What is the battery life like on your radios?

Most models offer 12–20 hours of battery life, suitable for full shifts. We also supply high-capacity batteries, multi-chargers, and spare batteries to support continuous operations.

Are the radios compatible with surveillance earpieces and microphones?

Yes. We supply a range of covert audio accessories, including acoustic tube earpieces, lapel mics, and push-to-talk finger switches, commonly used in crowd control and surveillance.

Can we track or locate guards using these devices?

Yes. PoC radios offer GPS tracking and live mapping, allowing supervisors to monitor guard locations in real-time for safety, accountability, and efficiency.

Do you offer radio systems for large venues or high-rise buildings?

Yes. For complex environments, we provide repeater systems, in-building antennas, and PoC solutions that ensure seamless coverage across floors, stairwells, and underground areas.

Can you help design and install a full communication system?

Definitely. Mobile Systems offers custom system design, radio programming, installation, and training—everything needed for a reliable and professional security comms setup.
