Backup Clients Assignment Dialog Box 
This dialog box allows you to select and assign backup clients associated with the selected client. This 
list includes only clients available for assignment by the current operator and defined as a client that does 
not exceed the limit of micros and DVRs allowed. When you select a client from the list, you will note that 
the client statement defines the total combined number of DVRs and micros of the default client and 
backup client. (The total number of micros cannot exceed 64. The total number of DVRs cannot exceed 
16.)

Select, and then click the left arrow to unassign a client. 
Click OK to display results in the Backup Clients list box. 
 
Backup Clients Tab 
Reference Topic:    
   
 
Client Form 
 This tab displays ONLY at client computers that are licensed for Client Redundancy. Use this tab to 
configure your backup clients that would take over the devices in case of a failure at the default client 
computer.  
Backup Clients:   
This list box displays those clients you have assigned to take over control of any nondirect micros and 
DVRs in the event of a failure at the default client computer. The order in which the client names display, 
determines which client is next in line to take over. The 
 is a variable. Backup 
clients must be online (Secure Perfect services are running). In the event of a failover, the client entry 
includes the client computer name, and then the total combined number of DVRs and micros of the 
default client and backup client. 
• 
Move Up: Select and click to move this client up the list.  
• 
Move Down: Select and click to move this client down the list.

Assign: Click to display a 
 dialog box, listing client computers 
found on your Secure Perfect system. Those computers selected and assigned when you 
close the dialog box, will display in the Backup Clients list box.  
Database Connection Heartbeat 
The Secure Perfect system validates communication with backup clients by pinging (sending continuous 
broadcast messages). If there is a communication failure between the default client and the backup 
client, the backup client looks for a Heartbeat (time stamp in the database) as an indication that the 
default client is online and connected. a) If a Heartbeat exists, the default client is "alive" and the backup 
client will not initiate takeover of the devices from the default client. b) If a Heartbeat does NOT exist, the 
backup client initiates takeover of devices from the default client. The backup client will use the following 
values: 
• 
Heartbeat (seconds): Select a computer from the Backup Clients list box and assign an 
interval of seconds (the range is 10 to 180) between Heartbeat checks. The default number 
is 60 seconds. This number can be reset at any time.  
• 
Heartbeat Retries: Select the number of times (the range is 1 to 3) this backup client checks 
for a Heartbeat stamp in the database, before initiating takeover of devices from the default 
client. The default number of retries is 2.
