Q1.
What is an IPcam?
A1. The camera that has built-in networking functions and
can be viewed on Internet is an IPcam.
There are different IPcams from basic to the high-end
on the market now. They may be built with different codec,
different features or different way to view. |
Q2. What’s the difference between VersaX Network Camera and the traditional IPcam?
A2. VersaX Network Camera is implemented by the latest technologies. The major
difference includes:
VersaX Network Camera |
The Traditional IPcam |
Fixed IP is not necessary. Login account name will list
all registered cameras - worldwide. |
User has to key-in the IP address of the camera to view
the video. |
Can authorize lots of sub-accounts with different priority
and privileges. |
A password to prohibit the unauthorized use. |
CHAP encryption password, guarantees the safety of usage
on Internet. |
BASE-64 encoded password, easy to be illegally used on
Internet. |
Display up to 16 cameras (from different locations) on
a screen at the same time. |
Can only view a single camera at a time |
A user-friendly utility is offered online. No need to
download ActiveX by browser since ActiveX is so easy to be blocked by
some software. |
A built-in web server supports user to view through a
browser by downloading the ActiveX when first time apply. |
Very smooth video due to improved TCP, UDP and other
communication protocols. |
Deploy the very standard TCP communication protocol. |
Features all DVR/ NVR functions, can be integrated to
be a large system for vertical applications. |
A stand alone device, designed as a component of digital
home solution. |
|
Q3.
Why CHAP is better than Base64 to protect the Password?
CHAP is an authentication protocol that only transmits the
MD5 result of “password +challenge string” on internet. The
challenge string is only valid to a certain IP for one time
connection.
Base64 is simple and reversible encoding protocol.
It’s easy and little efforts to restore the user name and
password from the network packet. |
Q4. Can I make sure there’s no unauthorized user is to view my VersaX camera?
A4. Yes. VersaX camera response to the viewer only after the
password is verified. Unauthorized user will not be able to connect
to VersaX camera. Of course, VersaX camera will not send the
video to the unauthorized user. |
Q5. Can VersaX Engineer view my VersaX camera?
A5. No. VersaX camera is protected by password under CHAP. The
database saved the MD5 result instead of plain password. VersaX
engineer is unable to connect to the camera without authorization
because MD5 is irreversible. |
Q6. Why a user to view the internet camera by a browser is not the best way?
A6. The major disadvantages to view internet camera by a browser
are:
1> A fixed IP or DDNS is not convenient for user.
2> Most of users do not know how to handle it when browser
helper blocks the downloading of ActiveX.
3> User name and password are transmitted on internet with
Base64 encryption.
VersaX Network cameras come with user-friendly client utilities
for different applications. |
Q7.Q7. Why VersaX network camera needs the VersaX_Loader?
A7. The VersaX_Loader is a tool to help user to manage and
update VersaX utilities.
VersaX_Loader makes the software
upgraded by just a click whenever needed. |
Q8. Why VersaX network camera needs different utilities?
A8. VersaX network camera is an all-in-one devise that can be
used as an IPcam and a DVR device.
1>VersaX_Viewer is to offer
the functions of a regular IPcam.
2> VersaX_DVR works like a regular DVR system. A VersaX
network camera itself is a DVR system and it can record the
video into a local PC or a remote NAS. |
