Analog monitoring slimming Coaxial cable power PoC new tricks

In order to attract the attention of more security users, many manufacturers have launched new concepts of monitoring
.
Especially under the general trend of network high definition, many monitoring products are not only similar in function, but also very similar in image processing methods, in order to pursue greater differentiation, make their own products more representative, new products continue to
flow.

The emergence of new surveillance products is not only for surveillance cameras themselves, from the introduction of HDCVI HD at last year's Amber, manufacturers will shift the focus to transmission, different transmission modes will collide with what kind of sparks? The PoE Ethernet transmission that is hotly discussed in the front-end time has now also encountered a strong enemy - PoC, and what surprises will the new technology have in the two-in-one mode of video transmission and power supply
.

Analog monitoring slimming Coaxial cable power PoC new tricks

Simply put, PoC is on par with PoE, which uses coaxial cable to power the battery and the latter to power over Ethernet
.
As a different transmission medium, there will be some differences
in the transmission effect.
The biggest disadvantage of network transmission is bandwidth, because the domestic network has not yet reached international standards, so the poor network upload speed has become an indisputable fact
.
The frequency bandwidth of coaxial cable can reach up to 1GHz, which can better serve data transmission and power supply applications
.

For this invisible data transmission volume, I am afraid that few people actually calculate
it.
Strictly speaking, if this fee is calculated clearly, it will also be a large expense
.
Similarly, in terms of cost price, PoC is also more cost-effective than traditional cable transmission, and the cost of traditional RVV1*2 line power supply is calculated according to the actual transmission distance, and the farther the transmission distance, the higher
its cost.

Surveillance camera PoE can choose from multiple power supply modes

PoC power transmission on the contrary, it requires more equipment, such as centralized power supply, signal mixing separator, modem, etc.
, but the unit price is relatively low, zero zero total is only 500 yuan, if multiple coaxial cables in the monitoring room share a power supply, the cost can also be expected to be reduced
.

PoC technology allows analog monitoring to slim down

So whether PoC is empty or true, it needs to be officially certified to be recognized
.
The HDcctv Alliance is the international association
that provides standards for HD-SDI video surveillance products.
Many domestic security manufacturers have joined the alliance, and product certification must comply with HDcctv standards before entering the market
.

It is worth mentioning that as the world's first PoC camera certified by the HDcctv Alliance, it can use the PoC (power supply via coaxial cable) function to be directly powered by the coaxial cable connected to the hard disk recorder, and the OSD menu of the camera can be easily controlled through the DVR, so the convenient monitoring system I believe that many people have heard of it for the first time
.
In this way, the analog monitoring system does not need to be transformed, since it supports coaxial power supply, it is also a good panacea
for the "slimming" of the analog system.
