Digital and analogue closed-circuit television (CCTVs)

Closed circuit television, or CCTV for short, has become increasingly popular for surveillance and security purposes. There is a long list of available and well-known manufacturers of CCTVs, among them are: Hikvision, Samsung Techwin, and Bosch Security Systems. Business uses of closed circuit television include protecting and conveniently monitoring assets, clients, employees, and materials while away. Residential uses of CCTVs are mainly for protection and security reasons but may include recording and monitoring of nannies, pets, and valuables.

What exactly is CCTV?

Closed circuit television is a system that allows a multitude of cameras to play simultaneously on a central monitor while recording. It is deemed “closed” circuit because signals are not publically distributed like regular televised screenings.

CCTV systems come in all sizes, functionality, and resolutions. Some high-tech systems offer zooming capabilities and are programmable, which means they’ll record on certain days or hours you indicate. Low cost CCTV systems may still be in black and white coloring, or recording in bad quality resolutions. Budget is the most influential when it comes to buying CCTV accessories. The neater the gadget the higher the price you’ll have to pay for the commodities. The basic rule is to shop depending on your home or business needs.

Analogue CCTV

This is the oldest system available and is mostly for use in low-budget circumstances. All of the footage will be chronicled through a VHS but only one camera is recorded at a time. They do have certain advantages over digital CCTVs that might be appealing for some users. Analogue CCTV do not crash or freeze. They are also cheaper and easier to install, along with being simpler to use. Small businesses can benefit from analogue options as long as a single angle can monitor and record the entire area of interest.

Digital CCTV

The digital option allows the recording to be saved as a digital video file (mpeg format is one example). Since the video file is digital, you can view and store it in computers, CD, DVD, USB, or memory cards. There is plenty of flexibility with digital files. You can decide to send them across a network, edit recordings to improve resolution or focus on certain time frames, and monitor recordings even when you’re not physically there. As mentioned before, digital CCTVs can also be programmable. They can be programmed to record on certain times or only when movement is detected. Also, digital closed circuit television systems usually come in sharper resolutions, impacting on the quality of the recording and overall file size.

Be aware that there are legal restrictions to take into consideration when installing closed circuit television systems. Get briefed on the laws that regulate their use in your state before buying and picking where to install. Not investigating the legal issues involved can lead to unintentional misuse and lawsuits. One known regulation is that closed circuit television cameras must only be placed in spaces that look unto your own property. No matter which CCTV you choose, analogue or digital, rest assured that you will feel peace of mind knowing that your valuables and investments are being cared for. If any incident should occur, you will have hard visual evidence in your favor. The mentioned brands are recommended by most CCTV experts but you can always research other possibilities.
