Introduction

The HD Helmet Camera is a 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 camera supports variable frame rate and bit rate adjustments as well as video resolutions,

which range from 1920x1080 down to 320x240. Integrated trigger capabilities and recording is also

supported. All of these parameters can be congured via a web browser interface.

The recording option features secure micro SD card storage. Access to the stored movie les is via

FTP transfer using the VE Camera Viewer software or an FTP transfer software tool.

The camera also supports control through the ONVIF protocol such that the camera can be

controlled by and viewed on ONVIF compliant VMS platforms.

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.

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.

Custom cable assemblies are available on request to interface with body worn radios from DTC,

Silvus and TrellisWare.

Connecting the Camera

HD Helmet Cameras are shipped with a custom interface cable as per customer specication.

Once the camera is powered and has an IP connection, users can web browse to the camera to

control its functions.

The web browser control of the camera’s encoder allows the conguration of parameters such as

resolution, bit rate, and network settings, once saved all conguration changes will be retained.

Browse to the camera’s web page by typing the camera’s IP address into the web browser address

bar.

Default IP Address

HD Helmet Cameras are by default set with a xed IP address of 192.168.1.195

If the camera is not responding on this address it is possible that the IP address has been changed.

If the new IP address is unknown, the user can use the VE Camera Viewer software application to

locate the IP address. This method is explained in the VE Camera Viewer section.

Camera Login

On trying to establish a connection the user will be prompted for the User Name and Password,

Control

Menus

User Menu

The user menu page allows users

to congure the user ID and

password of the camera. It is

necessary to conrm the password

to change it.

There is also the option to enable/

disable the following:

• FTP Server Connection

• OSD (On Screen Display)

• Audio Out

Changes are only enabled when

the submit button is pressed.

The primary mechanism for conguring the camera is its web browser interface.

The example screen below shows what is to be expected once a valid connection between the PC

and camera has been established by typing the camera’s IP address into the web browser address

bar. In this example it is the default address of 192.168.1.195

On the left side of the screen are the Control Menus which allow the user to congure various

settings in the HD IP camera. The functions of these menus are described in the following sections.

Date Menu

Update Menu

It is possible to update the

rmware of the camera. There are

three steps to updating the camera

rmware, as shown on the right.

Only update the camera

with les that have

been approved by Visual

Engineering.

Use of other les will render

the camera inoperable.

Tick this box and press

submit to sync the camera

to the PC time

The date menu page allows the user

to synchronise the camera time to

a SNTP server. In this instance it is

necessary to have the PC connected

to a network.

If a network connection is not

available it is possible to synchronise

the camera to the PC time by ticking

the “Sync Camera to PC Time” check

box and pressing the submit button.

The “UTC Oset” can be altered to

align the camera time with the local

time zone. To align the camera to the

actual PC time the “UTC Oset” should

be made same as the value displayed

in the “PC UTC Oset” eld.

3. Submit

the le

1. Select the

Update tab

2. Browse to

the le

Following a Submit the camera will update the rmware and display the following text:

Programming in Progress...Do not remove power

Wait until the web page clears this text before trying to move away from the current web page or

powering o the camera. Updates typically take approx 3 minutes to complete.

Important: To fully ensure the upgrade has nished it is advised to refresh the web page

and check the banner displays “HD IP Camera v4.00” or the camera starts to once again stream

video before switching o the power.

It is advised that following a rmware update that the Restore Defaults button is pressed, this

will revert the camera back to a default start state. The IP address of the camera will revert to its

default IP address of 192.168.1.195 following a power cycle.

Pressing the Reset button will completely re-start the camera.

Video Menu

The Video Page is where the

camera’s IP encoder parameters

can be congured.

The encoder supports two

encoding formats, H.264 and

MJPEG. The choice of the format

is initiated by the user when the

video stream is started.

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

It is possible to change the

Encoder Type to any one of the

following options:

• HD IP Camera

• PAL Input

• NTSC Input

• Guardian Node

• SWZ HD Camera

• LVDS Input 25Hz

• LVDS Input 29.97Hz

• SDI Input 25Hz

• SDI Input 29.97Hz

For normal operation it is not necessary to adjust the Encoder Type.

For correct camera operation it is important that the Encoder Type matches the hardware

conguration. For the Helmet Camera this is always the HD IP Camera type.

The RTSP Port is the port number the IP video stream will be transmitted on, this has the default

port number 554, which can be congured to another port number as required.

The Camera has two fundamental modes of operation:

• Constant Bitrate. This will output a constant bit rate IP video stream, as set in the Bit rate eld.

• Constant Quality. In this mode the bit rate 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’ bit rate is controlled by the value set

in the Bitrate eld, the encoder will attempt to limit the maximum bit rate to this value.

H.264 Resolution

The maximum resolution is 1920x1080, users can select lower resolutions if there is restricted

bandwidth available.

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 to the I frame interval balances the stream’s quality against latency, the

lower the number the lower the latency. Lower latency however can incur picture degradation due

to the eect of limiting the decoder buer.

Video Flip can be useful when the camera is installed upside down.

Video Reverse can be useful when viewing the image via a mirror.

Video Flicker can be adjusted to suit the local mains frequency when the camera is used under

articial lighting conditions.

Night Video Mode will increase the sensitivity of the camera under low light conditions.

LED Control Select either O or Auto mode for the LED type, the LED type will become active as

determined by the ambient light level.

Users should press the submit button to enable any changes.

Video Frame Preview

It is possible to view a single still image from the camera via a web browser using the following URL

format:

http://192.168.1.195/still.jpg

The above URL is applicable when the camera is set to its default IP address.
