Product description
Overview
Araani Fire Guard is an intelligent video surveillance solution, that will trigger an alarm if it sees smoke, smoke like
phenomena (steam, damp, dust) or flames.
Araani Fire Guard is an edge-based video analytics software that runs on an Axiscamera. Although it cannot
replace a primary fire detector, Araani Fire Guard does support control room operators, surveillance guards and
security staff in preventing fires. Araani Fire Guard is typically used in situations where there is no obligation for fire
detection or where there is already detection in place, but you nevertheless want to have an earlier warning.
Araani Fire Guard is an early warning system. By detecting smoke and/or flames in a very early stage of a fire and
raising an alarm on the surveillance display, operators can verify the situation and take preventive actions to limit the
impact of an incident.
Araani Fire Guard runs on compatible Axiscameras and analyses the image real-time for any indication of smoke
or flames. When detected, it generates an alarm that can be overlaid on the screen as a text label as well as a dynamic
zone border, highlighting the location of the alarm in the field of view.

How to install Araani Fire Guard
System requirements
CAMERA REQUIREMENTS
The Araani Fire Guard software is compatible with a broad range of Axiscameras. To run the Araani Fire Guard, a
camera with recent chipset and firmware is required. For proper detection, the camera needs to have sufficient
resolution and light sensitivity.
The camera needs to comply with the following characteristics:
•Brand: Axis(https://www.axis.com/).
•Chipset: Artpec-6 or Artpec-7.
•Firmware: Latest qualified AxisLTS (= long-term support) firmware.
Firmware can be downloaded at https://www.axis.com/support/firmware.
Refer to your camera manual on how to install firmware on the device or follow the steps under Camera
firmware.
•Resolution: 1920 x 1080 or higher.
•Framerate: 12 fps or higher.
•Aspect ratio: 16:9 or 19:6 (*).
Notice: Check the Araani Fire Guard release notes to verify what Axis software versions are compatible with your
Araani Fire Guard software version. Using an incompatible or untested version may result in malfunction, errors or
detection performance issues.
(*) Attention: After changing the aspect ratio, a restart of the Araani Fire Guard software is required.
Additional requirements may be applicable, depending on site- and cabling specifics. such as:
•External power supply availability or power over Ethernet (PoE).
•Environmental requirements, e.g., temperature, humidity, etc.
•Safety requirements, e.g., protected zone, ATEX, etc.
•Etc.
Consider all these requirements when selecting the appropriate camera type. Axisoffers a wide range of camera
models to comply to specific field needs.
An up-to-date list of compatible cameras is available online:
https://www.araani.com/en/solutions/surveillance/araani-fire-guard/fire-guard-camera-compatibility/.
AXISSTREAMING LIMITATIONS
In setting up your system, pay attention to the fact that total streaming video capacity of an Axiscamera may be
limited. For Araani analytics to work properly, the camera should be capable of delivering an application-specific
video stream at HD (1920 x 1080) resolution. In combination with other video streams for recording, visualization,
etc., the total computational capacity of the camera could be exceeded which will result in failure of the analytics.
The amount and complexity of video streams that can be delivered simultaneously by an Axis camera is limited by
the performance of the processor. The computational load of a stream is expressed in megapixels per second (mps)
and is calculated using the following formula:
Pstream = horizontal resolution (pixels) x vertical resolution (pixels) x frame rate (fps = frames per second) /1.000.000

Version: 20210708 9
The total streaming capacity is obtained by adding the load of all unique streams. Only unique streams are counted
for as requesting twice the same video stream (same resolution, frame rate, encoding type, compression, etc.) from
a camera does not require separate encoding and as such does not increase the computational requirements.
PCPU = Σ unique Pstream
Araani fire detection analytics requires a stream of 1920 x 1080 at 12 frames per second, thus:
PAraani = 1920 x 1080 x 12 = 24,9 mps
This stream should be considered when calculating the total load.
The streaming load is practically independent of the encoding type (H264 versus H265).
The maximum capacity for a camera depends on the type of processor. Currently, two generations of processor are
common in the Axis offering, named ARTPEC-6 and ARTPEC-7. These are the limits for both processor types:
•ARTPEC-6 maximum total streaming capacity = approximately 310 mps.
•ARTPEC-7 maximum total streaming capacity = approximately 367 mps.
In case of doubt, contact your supplier to know what processor type is used in your cameras.
As video stream compression is occurring in a dedicated part of the CPU, these limits are practically independent of
other processor activities such as image optimization, mirroring or ACAP-based analytics.
For proper functioning of Araani fire detection analytics, make sure the total stream demand - including the required
analytics stream - does not exceed this limit and preferably add some margin. If that limit is exceeded, the camera
will lower the frame rate on ALL streams and as a result, Araani analytics will no longer work.
Example: A 4K CCTV system requires one high resolution stream for visualization and one HD resolution stream for
recording.
Stream role
Resolution
Pstream
Visualization
3840 x 2160 @ 25 fps
207,4 mps
Recording
1920 x 1080 @ 25 fps
51,8 mps
Araani analytics
1920 x 1080 @ 12 fps
24,9 mps
Total
284,1 mps
The total load in this example is well below the limit of both processor types, so this will work fine. Adding another
HD recording stream with different settings for example would exceed the maximum performance of an ARTPEC-6
based camera and analytics will fail to run on such combination.
LENS REQUIREMENTS
Selection of the lens depends on:
•Field of view to cover. Most lenses today are multifocal, allowing adaptation at installation time to fit the
environment. Online lens calculators can help to select the proper focal range.
•Area of risk.
•Light conditions: day / night / seasons.
•Light stability / light changes.
•Uniformity of illumination.
•Interchangeable lens.
•Etc.
Consult with your camera supplier for proper selection of the lens type and specifications.

Version: 20210708 10
ENVIRONMENT REQUIREMENTS
The sensitivity and performance of the Araani Fire Guard system are impacted partially by the environment it is
operating in. Consider these basic guidelines with each installation for optimal performance:
Light:
For smoke recognition, there should be sufficient light 24/7 in the complete field of view.
As a general guideline, smoke recognition requires light from 5 lux onwards, depending on the exact camera model.
However, the minimal required light level is dependent on the exact camera type.
Flame recognition does not require light = 0 lux. It works in complete dark environment.
Notice: Using (built-in) infrared illumination is possible but will disable the flame detection as for flame
detection a colour image is required.
Dark / bright spots:
Avoid combination of very dark and extreme bright spots in the field of view. This will stress the dynamic range of
the camera and make the image quality unstable, resulting in an overall darker image.
For indoor cameras:
•Do not point the camera to exterior windows, and portals.
•Avoid the presence of direct light sources in the field of view. If this cannot be avoided, adjust the
detection zone to mask these areas out.
For outdoor cameras:
•Avoid east or west orientation, where the sun gets low and potentially may blind the camera.
•Avoid having horizon in the field of view of the camera at all.
Contrast:
There should be sufficient contrast in the field of view. Do not point the camera to white walls or large areas without
contrast.
Sun:
Avoid direct sunlight or bright reflections of the sun falling straight into the lens.
False triggers:
Avoid sources of dust, damp, or smoke (e.g., from operating machines) in the field of view during normal operation.
These could lead to recurring false detections.
Outdoor:
Outdoor conditions are more susceptible to false alarms. For outdoor applications, try to control and stabilize
environmental conditions as much as possible e.g., protecting the scene from varying weather conditions, apply
stable lighting conditions, etc.
To further optimize the detection or to avoid false triggering of alarms e.g., due to very dynamic or badly illuminated
zones in the field of view, the detection can be restricted to certain zones in the field of view. These zones can be
drawn in the app configuration screen in the browser itself, see section Configuring detection zones.
By default, the detection area is the whole field of view. If detection zones are defined, this will override the default
and detection will only occur only in the defined zones.
Adjust the sensitivity parameters of Araani Fire Guard if problems persist.

Version: 20210708 11
Camera positioning
SITE ASSESSMENT
For maximum protection, it is recommended to perform a site survey before installing cameras with Araani Fire
Guard. This allows you to identify risk areas and take those into account when positioning new cameras.
•Define the hot spots:
What is the type of risk? Can the fire start at any location in the field of view or is there specific risk related
to a machinery or a critical part of a scene?
•For smoke detection, estimate the smoke flow:
Estimate where smoke may flow in case of an incident. Dependent on this estimation, preferably select a
camera position that will visualize the smoke in the fastest and largest way. Focus on where the smoke
will flow, rather than the risk area.
Will smoke ascend to the ceiling or will there be stratification?
Will smoke be dispersed over the whole area by ventilation or forced air flow?
•System redundancy:
To guarantee full coverage on very large areas, multiple cameras will be needed. To avoid blind spots,
make sure the field of views of the cameras overlap with a minimum of 20%.
CAMERA POSITION / FIELD OF VIEW
Based on the site assessment, preferably select a camera position that maximizes the visualization of potential
smoke or flames.
•At default sensitivity level, Araani Fire Guard algorithm will trigger alarm when smoke covers
approximately 3% of the field of view during 5 seconds at the same location in the field of view.
•Araani Fire Guard algorithm will trigger alarm when the flame size exceeds 0,2% of the field of view and
the flame was detected for at least 20 seconds at the same location in the field of view.
For a camera with 1920 x 1080 resolution, 3% is a zone of 249 x 249 pixels and 0,2% is a zone of 64 x 64 pixels.
As an indirect result: the smaller the field of view, the higher the sensitivity, and the further away from the camera,
the lower the sensitivity.
The minimum required coverage for smoke and flames to be recognized depend on the sensitivity setting as per
table below.

Version: 20210708 12
Adjust the zoom / focus of the camera lens according to the Axisfocus procedure as described in the camera
manual. Do not forget to tighten the screws after setting up the focus and zoom to ensure they stay fixed.
Also consider the environment requirements described above when positioning the camera and adjusting the field
of view. In large areas, you may consider providing redundant coverage by adjacent cameras.

If in low-light conditions the image does not reach the required image quality, please adjust in this order: 1. shutter
time 2. gain 3. tone mapping. A higher shutter time may cause more motion blur, but this does not affect the
detection. A higher gain will cause more noise in the image which may interfere with the detection algorithm. A higher
tone mapping will change the colors and will influence the flame detection.
