Introduction

Video solutions. Integrated
HD Cam
The HD Cam is a full HD IP camera which can be connected directly onto a helmet Picatinny rail mount, making it suitable for use in tactical situations.
The camera integrates directly with the Visual Engineering Body Worn Mesh Radio. When coupled with the BWM it provides a complete end to end surveillance system.
The camera has exceptional performance in low light conditions and is supplemented with built in Infrared or white light LED Illumination.
The HD Cam supports variable video resolutions, which ranges from 1920x1080 down to 320x240. Variable frame rate and bitrate adjustments are also possible. All of these parameters can be
congured via a web browser interface.
The outer casing is CNC machined aluminium, this rugged build together with its IP67
environmental rating produces a camera that is t for deployment into tactical eld operations.
The camera is designed to have ecient use of power, all connections including power and IP video
are combined into one Fisher connector on the rear of the housing.
June 2018
A button mounted on the top of the camera controls the activation state of the LED Illuminator. At initial power on the LED will switch on in low light levels determined by the integrated ambient light sensor. Following power on if the button is pressed it will disable the LED regardless of light level.
Further presses of the button will cycle the LED to rst switch back to auto state and then o and so
on.
Custom cable assemblies interface with body worn radios from Silvus and TrellisWare.

Video Menu

The Video Page is where all the camera’s IP encoder parameters are controlled.
The encoder supports two encoding formats, H.264 and MJPEG. The choice of the format is initiated by the user when the stream is enabled.
To initiate a H.264 stream from a camera with an IP address of
192.168.1.195 the URL is:
rtsp://192.168.1.195/h264
To initiate an MJPEG stream from a camera with an IP address of
192.168.1.195 the URL is:
rtsp://192.168.1.195/jpeg
June 2018
The Video page contains parameters for each encoder type. The Camera has two fundamental modes of operation:
Constant Bitrate. This will output a constant bitrate IP video stream, as set in the Bitrate eld.
Constant Quality. In this mode the bitrate is varied in a eort to maintain a constant quality.
The target quality is set using a number between 0 to 51, the lower the number the higher
the quality, this is set in the quality eld. Amendments to this value are only allowed when the
constant quality mode is enabled. In this mode the ‘ceiling’ bitrate is controlled by the value set
in the Bitrate eld, the encoder will attempt to limit the maximum bitrate to this value.
Other video encoder parameters include:
H.264 Resolution
The maximum resolution is 1920x1080, users can select lower resolutions if there is restricted bandwidth available for the camera’s connection.
H.264 FPS (frames Per Second) The maximum frame rate is 30fps, users may choose to select lower frame rates, thereby reducing the bandwidth required.
H.264 IDR Frame changes the I frame interval in the H.264 stream by setting the parameter, this balances the stream’s quality against latency. The default value is 30.

Recording Menu

The integral SD Card in each camera node has a capacity of 32GBytes, this oers 17 hours of
continuous recording at a total IP bit stream of 4Mb/s or 34 hours at 2Mb/s, etc. If recording capacity is achieved there is a user option to either stop recording or overwrite. The recording web page menu is shown below.
Note: Recording is temporarily paused during activity on the camera’s web interface.
Timed Recording
There are 4 options for timed
recordings, these are; O,
Continuous, Once and Daily.
O = No recording takes place.
Continuous = Recording
Continuously.
Once = Record once when the
start time is reached and record for the set duration.
Daily = Record daily starting when
the start time is reached and record for the set duration.
Trigger Recording
Trigger Recordings can be triggered by either motion or light level change. Trigger recordings are disabled by default, if enabled, a recording will be made. The duration of the recording will be the duration of the motion event plus the time set in seconds in the trigger duration.
SD Card Management
In the event of the SD card becoming full, there are two options for Overwrite Control. One option is to have the recordings stop when the SD card is full, or the other option is to have the oldest material to be overwritten when the SD card becomes full.
Following any changes made in the menu the user must press the submit button . Wait until the
camera nishes re-conguring before powering o the camera.
Erase and Format
The SD card will be completely erased and formatted if the Erase button is used. The user will be
asked to conrm that this is the intention before the SD card memory card is actually erased.

Recovering Recordings

Video solutions. Integrated
HD Cam

Record Format

Recordings are stored on the SD Card as individual 10 second duration .avi les. This is for a maximum frame rate of 50fps, lower frame rates will increase the length of the stored le
proportionately. For example a frame rate of 25fps will create a 20 second video clip.
Video clip lengths are kept intentionally kept short, this allows integration with The VE Camera
Viewer so that recent events can be played back with a low data upload overhead.
The le size is proportional to the total bitrate selected by the user.
The les follow the a naming convention of:
YYMMDDHHNNSS
For example a le with the name of: 170801134611 would have the meaning:
YY = Year is 2017 MM = Month is 08, August DD = Date is 01, the 1st of the month HH = Hour is 13, 24 hour format NN = Minutes is 46 SS = Seconds is 11
June 2018
Additionally les containing motion will have an ‘m’ appended on the end. This is so any video clips with movement in the video can be easily identied. When searching motion les it is advisable to also check for activity in the video in the le preceding any motion tagged le.
For the le described above with motion in the video it will have the complete le name of:
170801134611m.avi
Recordings are stored in directories for each individual hour, the directory has the form: YYMMDDHH
Since each le is 10 seconds long there will only ever be a maximum of 360 les in each directory.
Recordings can be accessed and downloaded via FTP (File Transfer Protocol) using either The VE
Camera Viewer or an FTP application such as FileZilla.
The VE Camera Viewer is available to download from the VE website at:
www.visualengineering.co.uk/supportdownload/26
FileZilla is a free application and can be downloaded from
http://sourceforge.net/projects/FileZilla/
If using FileZilla, downloaded recordings can be played in players such as VLC either individually by selecting Play stored File or in groups by creating a play list.
