Eye visual doorbell architecture
The cat's eye visual doorbell consists of three parts: an outdoor unit (outdoor camera and indoor signal transmitting host), an indoor unit and a lock controller.
Cat eye video doorbell outdoor unit
The outdoor unit has four main functions:
(1) The image signal and the voice signal are respectively collected by the cat's eye camera and the microphone, and the collected analog signal is analog-to-digital converted into a digital signal. The cat's eye main processor compresses and enhances the speech and digital image signals, and then transmits the compressed signal through the wireless signal transmitter;
(2) transmitting a control signal generated by a peripheral device such as a cat's eye doorbell button through a wireless signal transmitter;
(3) The wireless signal receiver receives the wireless voice signal transmitted by the indoor unit, and the cat eye main processor decompresses the received voice signal, and then converts the digital to analog signal and plays it through the speaker;
(4) The wireless signal receiver receives the control signal from the indoor unit, and the main processor converts the received control signal into a lock control command and transmits it to the unlock controller through a short-range wireless transmitter (usually using the Zigbee protocol).
The cat's eye visual doorbell outdoor unit has three main functions:
(1) The wireless signal receiver receives the wireless voice or video signal from the outdoor unit, and the main processor performs processing such as redundancy and decoding on the received signal, and then displays the decoded video signal through the display screen, and the decoded voice signal is decoded. Converted to an analog signal by D/A and played out through the speaker;
(2) transmitting control signals generated by various peripheral devices of the indoor unit, such as a call, an unlock, etc., through a wireless signal transmitter;
(3) The voice signal is collected by the microphone, and the collected analog signal is analog-to-digital converted into a digital signal, and the main processor compresses the voice signal, and then the compressed signal is transmitted through the wireless signal transmitter.
Cat eye visual doorbell unlocking controller
The unlocking controller is mainly used to realize wireless remote unlocking. A controller that embeds various smart locks (electric locks, magnetic locks, mute locks, fingerprint locks, and combination locks) in the unlock controller. When the unlocking controller receives the wireless control signal from the outdoor unit, it generates a signal for unlocking by decrypting and decoding, thereby unlocking the remote control.
The cat's eye visible doorbell has the following features in the architecture:
(1) Adopting an all-digital color camera with infrared night vision function;
(2) Displaying video using different sizes of liquid crystal displays;
(3) Using 2.4G wireless transmission technology to transmit video, audio and data information, the video transmission rate can reach 30.
(4) The outdoor unit and the indoor unit are all powered by standard lithium batteries, which truly realize wireless installation.
We can produce the lower-temperature Steel Pipe according to the ASTM A333 and ASME SA333 standards, and the and the production
diameter from 8" to 48" in OD and wall thickness from 9.53 mm up to 140mm. We have been sold the GR.6 steel pipe about 20000 tons
to date and the property of -45℃ impact value is about 100J, better than the standard`s
requirements.
Yangzhou Chengde has the full capability to do every
test in-house, from mechanical testing, chemical analysis, PMI, UT/Hydrotest
etc. Chengde`s lab is qualified to ISO 17025 and CNAS standard, being proven
the repeatability of accurate testings.
Each alloy pipe is subject to PMI before
dispatch. The INNOV-X system performs non-destructive chemical analysis via
simultaneous detection and quantification of fluorescent x-rays of multiple
elements in test sample.
