When you're searching for equipment to purchase or looking for providers of jail services, a good starting point might be the following two online resources:

• The American Jail Association Product Service Resource
• The National Sheriffs' Association Ultimate Guide for Sheriffs

Also, don't forget the National Law Enforcement and Corrections Technology Center (NLECTC) which may be able to assist with property acquisition.  Programs are available where federal surplus is sometimes available to jails at little or no cost.
