2 Overview
OZ-LEHAVA is a Pan Tilt Motorized Thermal Fire Detection Network Camera for real-time
fire detection. The system scans predefined targets and automatically discovers fire by
directing the camera’s heat sensor to given locations.
The OZ-LEHAVA application provides an easy to use UI system control. Once activated, it
can be monitored on any network connected PC. Fire detection alerts can be sent in several
forms, such as visual (on screen), Digital output, and Audio alarm (only for the PC on which
the application is installed). All these features make OZ-LEHAVA a perfect cost-effective
solution for the outdoor fire detection.

4.2.5 ‘Send DO to Decoder’ Configuration:
The OZ LEHAVA application sends two digital outputs via the encoder to the decoder
DO1 for saying “I’m Ok”, a pulse (signal ‘true’ followed by signal ‘false’) that is sent
every few seconds to initial the timer unit.
DO2 for ‘Fire Alert’ or an error: a signal ‘true’ is sent. “No fire detected” disables the
‘Fire Alert’ signal (set it ‘false’).
If DO1 pulse has not been received by the decoder for more than 10 seconds, or DO2 has
signaled “true”, the buzzer sends an alert.

RTSP Authentication: Enabled
Enable/Disable RTSP Authentication by 'Device->Authentication: Username' and
'Device->Authentication: Password'.
RTSP Port
The RTSP port used for streaming the device video (554 by default)
Session Name
Allowed characters: Numbers, Digits and '_'
Maximum name length: 64 characters. Usually, there is no need to change the
default value.
Note: Any change to this property must correspond to the encoder’s values.
Otherwise, it is impossible to view the video on the device.
Video Stream Type
The video transmission method
o Unicast->every viewer gets the video directly from the device. In this case,
more CPU power needed from the device.
o Multicast->The video is transmitted from the device only to the router, which
multicasts the video to the viewers. In this case, less CPU power is needed
from the device.
Note: Any change to this property must correspond to the encoder’s values.
Otherwise, it is impossible to view the video on the device.

8.2 Presets+ Panel
A click on the Presets+ button ( ) will open the panel
shown on the right:
(A) Preset Numpad : Here you can input preset numbers.
(B) Preset Actions :
Go To Preset
Goes to a preset position/performs a preset action
provided by the camera. (For example, preset 95 in
most Pelco D cameras initiates the camera menu).
Usage: input the preset number and then press ‘Go To’.
Set Preset
Saves the current position as a preset of the camera
Usage: input the preset number and then press ‘Set’.
Clear Preset
Clears the selected preset number from the camera’s
presets
Usage: input the preset number and then press ‘Clear’.
(C) Continuously Query Position
When checked ( ), the program continuously asks the
camera for its current position, and records it in the PTZ
Current Position boxes (B on the Main PTZ Panel).
Right-click it to see the menu on the right ->
Check the ‘Estimate Responses Opcodes’ in case the
PTZ positions are not updated upon change of
position. (Some cameras do not fully follow the Pelco D protocol, and with this
property we attempt to fix it)
The query interval can be changed by selecting a value from the drop-down list
and hitting ‘Update Query Interval (ms)’
Note: PTZ devices cannot handle too many commands/queries in a short
period of time. (In this case, the interval must be increased). Vice versa, if
positions are refreshed too slowly, the interval may be decreased.
(D) Fixed Commands : Select one command from the list (for example, ‘Flip 180 degrees’)
and hit Go( )
Note: An action will be done only if it is supported by your camera.
(E) Extended Commands 1 : Select one command from the list (for example, ‘Set Zoom
Speed[0-3]’) , enter a value below and hit Go( )
Note: An action will be done only if it is supported by your camera.
(F) Extended Commands 2: Select one command from the list (for example, ‘Set Pan
Position’), enter a value below and hit Go ( )
Note (1): An action will be done only if it is supported by your
camera.

8.3 Record/Play PTZ Scripts Panel
In some cases you may wish to use PTZ scripts in order to
perform daily tasks on your camera. For example, you
might want to change the position of the camera at specific
times of the day, or change the day/night camera mode at
specific times (in case your camera does not have this
option built-in).
In this software you have support of PTZ scripting that
enables you to record and play a script.
The following actions are available:
Record: When you hit the Record button, it will
light up ( ) to signify a PTZ recording session. In
this session, until you will press the Record button
again, you can command the camera to perform
actions while using the Main PTZ Panel or the
Presets+ Panel. Every command will be added as a
line in the PTZ script, as shown below:
Note: Every line consists of a command and a delay,
which is the time (in milliseconds) to pass until executing the next command.
Stop Script : Stops the script and moves the player cursor to the first line (as shown
below):
Pause Script : Stops the script at the current cursor position (as shown below):
Play Script :Plays the currently loaded script from the current cursor position (or
from the beginning if the cursor is not set)
Play Current Command : Plays only the command that is under the player cursor
Clear Commands : Clears all the script commands
Save PTZ Script : Saves the current script to a file
Load PTZ Script : Load a PTZ script from file
