Standard Positioning Range

The Oculus is a professional vandal-resistant, high speed

continuous rotation PTZ. The housing has been cast in

aluminium which is then anodised and powder coated to allow

the unit to be installed in harsh and challenging environments.

The toughened glass viewing window is optically correct and

distortion free to provide brighter, clearer images even at full

telephoto zoom range. The range is available in both video and

thermal imaging options, with or without IR and White light

illumination, and all models have a wiper as standard to keep

the glass free from build-up of dust or debris. It is an all-round

performer and with its multitude of camera options it will

perform in all weather conditions.

Standard Positioning Range

The Aeron PTZ camera is designed to meet the increasing

demand for long range thermal and video surveillance

in a discreet but, robust housing. Building upon the successful

Oculus base frame the Aeron is a compact, rugged continuous

rotation PTZ camera. The Aeron incorporates all of the

mechanical advantages renowned in the Oculus with the ability to

incorporate thermal cameras with larger lenses of 100mm

and 100mm optical zoom. This increases man detection up to

an impressive 3000m with the option to optically zoom for closer

inspection. Video verification is provided by either HD or SD video

zoom camera with simultaneous output to the thermal. Aeron can

now be supplied with radiometric thermal cores for fire detection.

Standard Positioning Range

The Osiris PT platform is specifically engineered to handle larger

and heavier camera units. It is the big brother to the Oculus and

incorporates all of the benefits while also giving the user the

option to use a multi sensor approach in hi-security applications

when accurate positioning and long range detection is required.

It is available with three off-the-shelf camera housings to allow

lenses of up to 700mm to be incorporated within a robust IP67

enclosure. Just like the Oculus, there are a multitude of camera

models, including low light and thermal and illumination using

LED and laser technologies to ensure images can be seen in all

weather conditions, including mist, fog and desert storms.

Image shows the Kelvin Hughes Radar integrated with Jaegar.

Standard Positioning Range

The Jaegar PT platform has a built in through shaft that allows

radars or other payload to be mounted on top and remain

stationary as the PT surveys the scene. A wide range of thermal

and video cameras are available, all supplied in cable managed

housings for protection in the harshest environments.

With harmonic drive gears as standard the Jaegar is virtually

zero backlash ensuring the capture of stable images even at

very long distances over land or water. When twinned with

radar and absolute positioning control the Jaegar can be driven

automatically to any threat detected and remain on target as the

threat moves. As with all Silent Sentinel products the Jaegar

can easily be deployed as a standalone system or combined to

increase the performance of existing systems.

THERMAL IMAGING

Thermal Detection

Using the latest technological advances, Silent Sentinel brings affordable thermal imaging

technology to commercial surveillance and security applications. All models are designed

to operate without ambient light or illumination and will provide excellent image quality in

challenging environments. All can be used as a standalone security device or to enhance

the capability of any video surveillance system.

Thermal Imaging cameras measure heat and convert it into a visible image which makes

it ideal for zero light surveillance, and will operate in all weather conditions, even fog. The

cameras provide a high contrast image which is perfect for Video Analytics and motion

detection. Radiometric models will give an alarm output, when a parameter is breached

Silent Sentinel has a very extensive range of thermal imaging cameras for all

applications. When combined with a video camera as in the Oculus rugged

dome the best features of video and thermal are combined to provide

the user with a surveillance device to capture any event.

For extra-long range applications to protect any high asset value

property, the Silent Sentinel Osiris platform is the best choice

for security professionals, as it uses a broad range of uncooled

and cooled thermal cameras, combined with video and EMCCD

with a detection range of up to 20 KM.
