While coaxial cable is very easy and convenient to use, it does have limitations: Often it can be inconvenient to install coax cable and if UTP is available then there is a great incentive to use it.However, similar issues arise when trying to use UTP cables to transmit analog video signals.Jadi mirip sekali dengan remote CCTV :)meminjam slogan NOKIA, Ini benar - benar teknologi yang memudahkan dan menenangkan orang tua :)Teman - teman ada yang mau pesan ? heheheheberikut penjelasan lengkapnya : The 3G Mobile Cam is a wireless camera that can be placed in customer’s home or office and accessed via 3G video calls initiated by a 3G mobile phone from anywhere and at anytime.The easy to use 3G Mobile Cam will enable customers to enjoy live audio, video and a talkback facility whilst maintaining complete privacy by entering a security PIN code exclusive to each user.Currently, this technology is slowly succumbing to IP oriented technology although analog-like SDI uncompressed digital systems are gaining traction in some specialised applications.In all cases, copper based technology has limitations in terms of distance and interference immunity so that fiber is often the preferred, sometimes the only, way of distributing signals around CCTV networks.Customers can also enjoy 50% discount on the monthly rental when they subscribe to the yearly plan option.

Typically, passive or active Balanced-to-Unbalanced converters (Baluns) are used and these can provide reasonable transmission over a few hundred meters (even more with active cable equalisation).
The Ethernet systems typically deployed in local area networks are often used to transfer IP based video signals but as with coax and balun based analog systems, these also have severe distance limitations and are susceptible to EMC issues.
The 3G Video Call per minute is always 10 Dhr more than the voice per minute rate for postpaid and prepaid customers.
The postpaid Video Call per minute rate is 45 DHR during peak hours، and 40 DHR during off peak hours. As the owner/administrator of the camera، you are requested to create 4 digits security PIN.
