3G CCTV

Remote CCTV has been a popular and sometimes essential feature of modern Security systems for some time. Remote access can be facilitated using a wide range of network topologies – xDSL, leased line, 802.11b/g WiFi networks or in some cases Microwave links. There are many applications where fixed line access is not available or practical such as construction sites, mobile CCTV, rapid deployment systems, or temporary CCTV installations.

With many modern Security systems now supporting the H.264 codec, or their own advanced proprietary compression algorithms, the bandwidth available through 3G broadband networks (typically 384Kbit/sec upload on HSDPA), provides usable image quality and frame rates over 3G mobile networks.

There are a few key points to consider when planning remote 3G CCTV access:

- The UK 3G networks provide private, dynamic IP addresses which cannot be accessed from the Internet (access is blocked by NAT firewalls). You will need a public static IP address to successfully implement 3G CCTV access.
- You must select a provider with good network upload speed for high frame rates and better image quality
- You may require an external antenna to maximise throughput on your 3G connection
- Select 3G router best suited for your application.

Wireless CCTV

Network Wireless CCTV installed on a pole. Easy to install, quickly deployed.The VideoWave series from Cam-tech is your answer to problem free transmission of Video signals and is available in either 1.4GHz, 2.4GHz or 5.8GHz versions.

The analogue VideoWave is designed to send and receive composite, real-time Video signals from CCTV cameras and related products using wireless technology. VideoWave is a high quality product aimed at the top end of the market and boasts proven Video processing technology (PAL, SECAM and NTSC) together with up to 500mW power output where local regulations permit.VideoWave can be used in conjunction with our Radio Modems (RM9600 series) for over-air telemetry control of PTZ cameras. VideoWave Digital is based on the 802.11 WLAN technology, especially adapted for transmitting video and telemetry in the 2.4GHz and 5.6GHz license free bands.

The system is flexible, offering various configurations from simple point-to-point to multiple camera applications, with built in telemetry for PTZ control, where required.VideoWave Digital works with standard analogue CCTV cameras, DVR, matrix switch, monitor etc. so can be used as a stand alone wireless system or as part of a larger installation.Applications Include: Security, CCTV, Covert, Remote Site Monitoring, Mobile, Surveillance, Air to Ground Link.Approvals: All RDT products from Cam-tech meet the required local approvals including: R&TTE Directive 1999/5EC, EN300 220-3, EN 300 113-2, ETS 300 440, MPT 1349, EN 301 489-3, ETS 300 683, EN 60950.Other approvals can be obtained on request.
