Frequently Asked Questions
What is CCTV?
It is Closed Circuit Television.
What is a Security DVR?
DVR stands for Digital Video Recorder. A Security DVR is capable of taking the video from digital or analogue cameras and recording it into a digital format on a hard drive. It can record high quality video, maintenance free, for weeks or even months. An ideal replacement for time lapse VCRs.
What is a Security NVR?
A network video recorder (NVR) is a software program that records video in a digital format to a disk drive, USB flash drive, SD memory card or other mass storage device. An NVR contains no dedicated video capture hardware. However, the software is typically run on a dedicated device, usually with an embedded operating system. Alternatively, to help support increased functionality and serviceability, standard operating systems are used with standard processors and video management software. An NVR is typically deployed in an IP video surveillance system.
Network video recorders are distinct from digital video recorders (DVR) as their input is from a network rather than a direct connection to a video capture card or tuner. Video on a DVR is encoded and processed at the DVR, while video on an NVR is encoded and processed at the camera, then streamed to the NVR for storage or remote viewing. Additional processing may be done at the NVR, such as further compression or tagging with meta data.
Hybrid NVR/DVR surveillance systems exist which incorporate functions of both NVR and DVR; these are considered a form of NVR
What is a video capture card?
A video capture card or DVR card is a graphic card inside the Security DVR system which captures the signal from the cameras and stores the video on the hard drive.
How many hours of video can the Security DVR store?
The length of archive depends on number of cameras, frames per second (FPS) and amount of available hard disk space. Our preconfigured systems usually provide several weeks of archive on motion detect mode.
Do you have to have a sign to say recording CCTV
No if its just in your home. However, when big businesses are recording they must have a sign to state they are recording members of the public.
What are the rules regarding CCTV in the home?
The rules are you must not intrude into your neighbours property when the footage is filming. You must have the correct time and date at all time when recording footage. You are responsible for any footage that is on your hard rive, this means you need to regularly delete any footage that is not needed to be stored. The is also a rule regarding the use of the footage. You are allowed to record to protect your property but you must not share this footage on any social media platform as this is a breach of the Data Protection Act that you must follow.
Can I view live and recorded video locally?
Can I view live and recorded video remotely?
Yes, most of our Security DVR systems are Internet enabled. You can view live and recorded video from anywhere through the Internet.
What kind of broadband do I need? How much bandwidth?
Basic DSL or cable will suffice in most cases.
Can several users view one site at once?
Most Internet-enabled Security DVR systems allow multiple users to view the same systems recordings. However, as more people look at the same cameras/DVR at the same time, the bandwidth will be shared between them.
How many cameras do I need?
This will depend on the size and layout of the area you wish to survey. We prefer to arrange a free survey so we can help you decide this.
Can I use my existing cameras?
Yes, you can use your existing CCTV cameras. We do repair old already existing cameras and we can also use already installed ones but this would depend on the system, if you contact us prior to making a order we can do our best to give the right advice, most camera systems either run on TVI, AHD, CVI, CVBS or HD-SDI. most systems on the market today are what we call Hybrid,
What camera lens size is the best for my application?
There is a large selection of security camera lenses, but the lens you will need depends on where you plan to use it. When the survey is completed we can advise based on your desires for your property.
Can I zoom in with a camera?
Yes, but you need a special camera called a Pan-Tilt-Zoom or PTZ camera. We again can advise this on the survey.
What type of Operating System (OS) does the Security DVR use?
Most PC-based Security DVR Systems use Windows 7 Professional, and Standalone Security DVRs are Linux based.
What kind of cable should I use?
This is something we can advise on the survey. We sell them online at our other website. www.kreative-cctv.co.uk this you can see the different cables that we use.
What happens if there is power outage?
Most Security DVRs will come back on as soon as power is restored. However, we suggest an uninterruptable power supply (UPS) which provides a short period of backup power and also serves as a surge protection device.
