Security Two-Way Radio System Buying Guide

Most security operations do not need one radio model for every officer. They need a planned fleet: dependable radios for patrol and front desk, durable models for exterior and parking posts, enough channels to separate dispatch from patrol, and a coverage strategy for garages, stairwells, loading docks, and multiple sites.

How many radios does a security team need?

Count posts and shifts rather than the total number of officers. A radio assigned to a post, such as dispatch, front desk, a patrol route, or a parking structure, stays reliable across shift changes and covers the officer who is actually on duty.

These numbers are planning ranges, not purchase requirements. Building materials, site layout, the number of simultaneous posts, existing radios, and post orders can all change the final recommendation.

Choose radios by post and coverage

Front desk, lobby, and patrol officers

Prioritize simple controls, clear audio, and batteries that comfortably last a full shift. The license-free Motorola Curve DLR110 suits a small indoor team, while the Motorola CP100d adds programmable channels for a growing operation.

Supervisors and exterior posts

Parking structures, loading docks, perimeters, and bad weather demand stronger durability and audio. The Motorola BPR50dx and the digital Motorola R7 hold up to daily security use and deliver clearer audio in noisy areas.

Dispatch and control room

A display radio helps a dispatcher confirm channels, contacts, and status at a glance. The Motorola R7 with display is a common choice for a control post that coordinates several patrol channels.

Roving patrols, vehicles, and multiple sites

When communication must reach across a city or several properties, LTE push-to-talk connects officers over a managed nationwide network. The Motorola TLK110 handheld and the vehicle-mounted Motorola TLK150 use WAVE PTX service, and the Motorola TLK25 adds Wi-Fi push-to-talk for fixed indoor posts. A service plan is required.

Do security radios require an FCC license?

Most UHF and VHF business radios operate on frequencies licensed under FCC Part 90. Models such as the CP100d, BPR50dx, and R7 generally require an appropriate business-radio license and programming for the frequencies your operation is authorized to use.

• License-required radios: UHF and VHF business radios operating on licensed Part 90 frequencies, including the CP100d, BPR50dx, and R7.
• License-free radios: The Motorola Curve DLR110 operates on 900 MHz FHSS and does not require an FCC frequency license, which suits a small indoor team.
• Subscription-network radios: TLK110, TLK150, and TLK25 radios use WAVE PTX service and do not require a separate FCC radio-frequency license.

A practical security channel plan

A channel plan keeps routine patrol traffic from competing with dispatch or an active incident. A typical starting structure looks like this:

CTCSS or DCS tones can reduce unwanted audio from other users on the same frequency, but they are not encryption and do not make a channel private. Operations that handle sensitive communications should discuss digital privacy and encryption options during system design.

Where security radios lose signal

Coverage problems usually come from construction and site layout rather than a radio's advertised range. Test the places officers are most likely to need communication:

• Parking garages and basements: concrete and steel decks are among the hardest places for a handheld to reach.
• Stairwells, elevators, and mechanical rooms: dense construction often creates isolated dead spots.
• Loading docks and back-of-house: metal doors, coolers, and long corridors can separate posts from the main floor.
• Perimeters and open sites: the far edge of a lot or campus may exceed reliable handheld-to-handheld coverage.
• High-rise and multi-building sites: distance and floor count can put upper floors out of simplex range.

If important areas fail a coverage test, the answer is usually a repeater or a professionally designed radio system, not simply buying more handhelds. Learn how TWRG radio systems work.

Radios during incidents and emergencies

Two-way radios support coordination, but they do not replace a monitored alarm system, an access-control system, a duress or panic-alarm platform, or a call to 911. A radio is not a silent alarm and does not by itself dispatch police. Your post orders should define who calls emergency services, who runs the radio net, which channel is reserved for urgent traffic, and how radio messages fit into your established response procedures.

• Include radio use in drills instead of testing only alarms and access systems.
• Use clear post names and plain language that every officer understands.
• Test the emergency or programmable-button workflow on every model in the fleet.
• Confirm that relief officers and contract staff know where radios are stored and how to use them.
• Review the communications plan with the appropriate safety and public-safety stakeholders.

Covering vehicles, patrols, and multiple sites

Traditional UHF and VHF handhelds are designed primarily for local coverage. When communication must extend across mobile patrols, city-wide routes, or several properties, LTE push-to-talk radios can connect users through a managed subscription network.

A common multi-site arrangement uses TLK110 handhelds for roving supervisors and TLK150 mobile radios in patrol vehicles, with TLK25 Wi-Fi radios at fixed indoor posts. Network availability, subscription management, talkgroup design, and device installation should all be part of the rollout.

How to manage the fleet after installation

• Assign radios by post. A numbered radio belongs to the front desk, a patrol route, or a parking post rather than a specific officer.
• Use centralized charging. Multi-unit chargers make it easier to confirm that every radio is present and ready at shift change.
• Keep an inventory log. Record model, serial number, assigned post, battery condition, and repair history.
• Test daily. A short check catches a low battery, damaged antenna, or programming problem before an incident.
• Review the system annually. New buildings, added posts, staffing changes, and new events can create new coverage requirements.
