Adopting one-card or dual-card binding technology, Crearo 4-channel
wireless CDMA video server realizes the sync transmission of
4-channel CIF video images, and the maximum frame rate per channel
is up to 12fps. With 3-5 seconds time-lapse on average and
bi-directional talk, it is suitable for the dispatch and command on
some mobile objects, such as ship, bus, long-distance carriage,
etc. It is also used for field monitoring in the occasion of base
station, power line, reservoir dam, etc. Aiming at the poor
condition of wireless network, Crearo offers select one from
fourmodel-CR1024C with the automatic jump function of 4 channel
videos. 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.
Different models support the sync transmission of 4 channel videos
or select one from four” transmission method. 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. Professional platform software support All the equipments are compatible with CreMedia video management
platform of Crearo, and they can con |
