How to set up your DVR for use with a TechProDDNS Domain
One of the problems with viewing your DVR remotely is that if your Internet service Provider or (ISP) changes your IP address, you may no longer be able to access your DVR. Once properly configured, the TechPro DDNS (Dynamic DNS) service eliminates this common issue.
The way it works is by providing you with a domain name, like the following “MyDVR.techproddns.com”, that will always resolve to your current IP address. If the IP address changes, the DDNS service is notified by the DVR and updates the domain name to […] Continue Reading…

How do I know if I have Double NAT or Triple NAT?
In my last article we talked about NAT and what it does, and Port Forwarding and what that is. This article is the second in that series.

NAT and Port Forwarding
What is NAT and what does it do?
NAT is Network Address Translation. There are different types of NAT, but we’ll stick to the easy non-technical explanation of ‘Many to One’ NAT.
Your router is a Gateway, or ‘door’ to the Internet. There are two sides to the router, the External (WAN) side and the Internal (LAN) side.
Your computer should be connected on the inside (LAN) with an Internal or private address.
Your computer will only communicate with IP addresses that are on your same subnet. (Address range)
Everything on the outside of the router uses different IP addresses and Subnets […] Continue Reading…

I will start by showing the different parts of a PTZ camera.
1. Parts of a PTZ camera

(b) Camera module
This is where the image CCD sensor, optical lens, and the motors that control Zoom and Focus are located.
(c) PTZ control board
The PTZ control board processes RS485 data […] Continue Reading…
