what two way radios band is the best to buy for a security company?

I am looking a good brand for hand held two way radios and a mobile radio that mostly law enforcement or security company like ADT uses for when they send there officers on patrol?

    Most law enforcement agencies are going for the "lowest bid" process.

    Read some news about how bad / poor communication probably contributed to the deaths of firefighters during the 9/11 world trade center response. At least in my area of the country, most of the police / fire / ems workers I have spoken to think the radio systems they have in use are not well-suited for the job.

    I'd check with groups in your area, because they are going to know the terrain and environment (legal and physical) better than most. Also check with your local FCC office and ham radio groups - both for any restricted airwaves ( certain regions of the country have incredibly strict limits on the frequency and strength of radios - as an example, there is a huge square region around Washington DC, where it is near-zero! )

    .. and for recommendations regarding local traffic. You could check with other agencies like FAA (airports), and FRA (rail), police/fire.. to see what frequencies they are using.

    You want your radio to be within legal limits.. but still have the strongest legal frequency

    ( stronger usually means more reliable, especially if you have a large area, or have trees, buildings, hills/valleys to cover)

    Some radios require licensing.. not terribly expensive or tough to get, but it may not be printed on the box(-es) for the equipment you buy.

    In an old security job I had, we used almost exclusively Motorola radios.

    Most of the radios were lower 0.5-1.0 Watt, because folks rarely were too far away from our primary office antennas.. AND, every car had a radio that acted like a signal relay from hand-helds up to the main & back. (early trunking) We were licensed, and had one base station, with a 200' antenna, as well as 3 repeaters around the county.

    Only a few hand-helds were higher strength.. 2W- 5W.. the 5W radios were heavy and tended to get warm (hot) to the touch after a few hours. Nobody ever wanted to use them.. and feared especially hanging them from a belt loop and possibly injuring oneself. - burns and long-term radio exposure fears.

    The only good thing about the high-wattage radios ( to the avg. employee).. was the weight of the unit and battery made it an excellent weapon.

    *keep stuff like this in mind when you distribute equipment to employees.

    Also decide if you want to pay a little more for reliability by adding a base station, and how big of a tower you can rent space on.. or build yourself;

    if you are going only handheld, then you will probably find dead spots, even in the most boring of terrain, but it greatly reduces your initial expense, and the need to have a full-time radio operator.

    Be sure to also instruct your employees that (unless you go cellular or encrypted) that the public and press have lots of radio scanners. Anything they say over the air is likely to be heard by others outside the agency. Watch out for silliness, vulgarity, and , well, anything not required and professional.

    If it is an option, you might even consider using the push-to-talk feature on cell phones;

    -- this gives you somebody else's established infrastructure, and employees don't have to carry as many separate devices. GPS tracking and other features could be added depending on your business needs. You don't have to buy a lot of equipment, and you can update every year or two under your contract.
