Crearo wireless CDMA video server adopts 3 key technologies with
self-owned intellectual property rights: H264 video compression
technology with ultra-low code rate, dynamic adaptation technology
with proper channel, reliable error-correcting technology in
transmission designed for wireless channel. With 3-5 seconds
time-lapse on average, the video image is clear and coherent, which
quality is higher than other similar products at home and abroad in
the same wireless conditions. Crearo offers tens of wireless CDMA video server models with 1-card
or multiple cards binding, which can meet the demands of different
industries, such as applied in wireless video transmission,
snapshot and wireless data-acquisition, emergency command, etc. Our
products are widely used in many industries, such as police, fire
fighting, road administration, urban management, environmental
sanitation, bus, passenger transport, electric power, etc. Features: Best visual effect Adopting H.264 coding with ultra-low rate, the maximum frame rate
can be up to 15fps for one card and 25fps for multiple cards
binding. With 3-5 seconds time-lapse on average and professional
image processing technology, it has good image continuity and
abundant image details. Its visual effect is better than similar
products at home and abroad in the same network conditions. Bi-directional talk Audio input style can choose LineIn or microphone, while output is
the Headphone signals. Surveillance and control center can shout to
multiple front-ends at the same time with clear voice, and the
client supports dual audio channel recording and keeps the talk
record. Real-time data acquisition With standard RS232 communication port, it offers high-speed and
eternal on-line serial data transmission. After connecting with the
data collector, it can realize the real-time data acquisition of
environmental parameters (temperature, humidity) and equipment
states (voltage, current) on the transmission spot. Flexible alarm linkage action With two-channel digital input and one-channel relay output, it
supports the front linkage action device. Alarm will automatically
trigger the digital output, upload the video, snap the images, and
trigger the device online. The amount of input and output
interfaces can be customized. GPS data transmission It supports the sync transmission of video, audio, data and GPS
positioning information, and supplies the function of GPS data
filtering and drift correction. GPS data forwarding was supported
by manager system software. It can be used combining with
professional GPS software or adopting the electronic map function
of CreMedia software. Wireless online function Crearo wireless CDMA video server supports the data transmission of
audio and video, meanwhile, it can be used as wireless Router
offering CDMA wireless Internet connection for users via attached
Ethernet interface. Message triggers online Except for supporting eternal online, alarm triggering online and
timing online or offline, it also can trigger online via message.
Users just need to click the messaging online, and the system
platform will automatically trigger the relative equipment line by
the manner of messaging, which can save the wireless network
resource and fee. Security encryption strategy Using CHAP protocol in the login process, the password was not
lucid transmitted to prevent vicious stealing. Adopting DES
encryption technology, the command access can reject the identity
disguise. With disturbing technology and short update cycle of
scrambling code, it can prevent vandal declassification. Meanwhile, system supports VPDN virtual dialing connection method
for personal network, thoroughly separate from the public network
to prevent the vicious attack. For the military users, we can offer
the encryptor that authenticated by national password management
committee (extra fee need to be paid for the encryptor). Other auxiliary functions It also owns other functions, such as: superposition of name and
time for the front video, multiple PTZ control protocol, area
motion detection with freedom setup of detecting sensitivity and
shield function of sensitive area. It offers built-in batteries and
mobile power supply module, convenient for being carried or applied
on the vehicle. |
