What is CCTV surveillance?
CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.
CCTV relies on strategic placement of cameras and private observation of the camera’s input on monitors. The system is called “closed-circuit” because the cameras, monitors and/or video recorders communicate across a proprietary coaxial cable run or wireless communication link. Access to data transmissions is limited by design. Newer systems make use of CAT5e (Network Cable) with POE (Power over Ethernet).
Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Modern CCTV displays can be high-resolution colour, providing the CCTV administrator with the ability to zoom in on an image or track something (or someone).
CCTV is commonly used for a variety of purposes, including:
- Maintaining perimeter security.
- Monitoring traffic.
- Obtaining a visual record of human activity.
The use of CCTV surveillance in public places has fuelled privacy concerns in many parts of the world.
What do I need?
For remote off site surveillance you will need:
- At least one DVR (Digital Video Recorder) or NVR (Network Video Recorder).
- Cameras connected to your DVR or NVR
- Permanent Internet Connection at a minimum of 1024KBPS.
- A Security Service provider that is able to connect to your DVR or NVR
- A Static Public IP (Internet Protocol) Address
- Or alternatively a Dynamic IP Address that is hosted by an external company
- Specialized software normally supplied by the DVR or NVR Manufacturer.
What will it cost?
Cost of a DVR/NVR system has dropped considerably over the past five years. Although a NVR system is a little bit more expensive on the initial outlay, the maintenance and upgrading capability is much better than a normal DVR analogue system.
There will only be a monthly cost for a static public IP from your ISP(Internet Service Provider), but this is normally a very costly exercise. The alternative is to use a external dynamic DNS company which will cost you a fraction of the price, although not recommended you can also use a free dynamic DNS, a large number of limitations with a free dynamic DNS service will cause unreliability and loss of video.

On what devices can I view my CCTV footage remotely?
You can use a range of devices to view a live feed of your CCTV System:
- Any Android Device (Cell phone, Tablet), as long as the Manufacturer has designed and released an “APP” for android.
- Any Apple Device (Iphone, Ipad) as long as the Manufacturer has designed and released an “APP” for apple software
- Personal Computer: On the personal computer you can use the manufacturers software or simply a Web browser, with using a web browser you can connect to the DVR/NVR from anywhere in the world as long as the Computer has internet access, and you have the correct static IP or dynamic DNS address.
Is it Live video feed?
Yes the footage will be live, although the manufacturer’s software, or internet browser will allow you to also remotely play back any recorded video. You can choose to view live video feed or play back an incident all from your location, wheater it is remotely or local
