Benefits and Drawbacks of Wireless CCTV Cameras

With continuous advancement in CCTV technology, it is no longer surprising that wireless cameras are now invented and are now out in the market. They are capturing a lot of people’s attention more and more today. CCTV cameras are very much in demand because of the government’s goal to reduce the crime rate in country. People are now confused as to which type of CCTV installation is best used. Here’s a helpful guide for you.

Benefits of Wireless Cameras

· They can monitor and record events on remote locations.

Using the Internet, these cameras allow you to monitor events even when you’re out of range. You can record and playback events over the internet using cloud applications. You can even watch your cameras even when you’re in another country, as long as you have an internet connection.

· They present better picture quality

Most wireless CCTV are digital. This means that they no longer use TV lines or analog settings. Digital cameras use pixels hence present better picture quality and better resolution. Facial identification is easier.

· They may be hidden to monitor intruders in places they least expect it.

Because wireless CCTV cameras are very much portable, you can hide them to catch intruders without much effort. You can simply set it up just wherever you want and start recording. This gives you more than enough evidence to prove your claim in case of a court proceeding.

· Wireless cameras are portable and cost effective.

Wireless cams are most beneficial because they can easily be moved from one place to another, where you need temporary observation. You don’t need permanent installation. Plus, with its wireless ability, you don’t need additional cabling for it to work.

Drawbacks of Wireless Cameras

· Requires a dedicated internet network

Wireless camera uses the internet to transmit video data over to your computer or the cloud network. This means that without the internet, the camera will not work or will not be able to send the video data; hence you would have no recording or the ability to monitor the camera.

· Easily affected by internet disruptions

Like mentioned earlier, these types of cameras only used the internet signal to transmit video data, if there is intermittency in the internet signal, its transmission will also be affected. This usually results to no video, very slow video transmission, which compromises your security in the process.

· No local recordings

Because wireless cam is just a one-piece-equipment, there are no local recordings that you may later on playback. This means that if the internet experiences latency in connection or intermittent signal or no signal at all, your camera is not going to work at all. You can opt upgrade your wireless CCTV to have local recordings. However, to do that it will require cablings, which opposes its main advantage of being portable and wireless.

In conclusion, wireless surveillance system gives you an edge for its portability and mobility, but it can also compromise your security. These cameras are best used for temporary observations. If security is very important to you, it is best to choose wired CCTV installations, where you can have back up recording and local monitoring. Wireless cameras are best used only as an addition to wired CCTV installations.

Home and Business Security CCTV Technology Evolving From DVR to IPTV

Like most businesses, the video surveillance sector tends to centralize and consolidate its systems to reduce costs and take advantage of new upgraded technology. This article discusses the advantages of an unexpected jump that could cause the premature obsolescence of Digital Video Recorders in the security industry. IPTV, or Internet Protocol Television, enables all business systems like access control, fire alarm, phone, and computers to operate under one network. Video transmission over a network utilizes what is known as a virtual matrix as opposed to CCTV matrix switches. To visualize the difference, think of the difference between the portable CD players people used to carry to play one album at a time and the iPods now in fashion that can store hundreds of thousands of songs.

In its first ten years of existence the DVR has created a seriously high quality method of storing video images without any of the degradation of the former standard, the analog VCR tape. DVR provides efficient fast search capabilities and easy reviewing of the video, however the digital cameras use a server with analog video inputs and they are hooked up by coaxial cable just like analog cameras. There are a limited number of inputs and outputs for connecting with other systems and devices so once the inputs are full, if you want to connect to a control center you have to add another unit. Another drawback is that most DVR software uses non-standard digitization, compression, and closed circuit codes. This makes high-level integration with communications centers difficult. Although DVR security cameras have integrated hi-tech features like motion video, pan, tilt, and zoom, the limits on their flexibility become obvious when compared to IPTV.

It seems surprising that a better format would appear so suddenly but IP solutions offer significant advantages that would lower overhead by reducing redundancy and peripherals, plus provide for a much easier management of the systems. This is especially true for multiple locations and companies providing or using centralized recording and monitoring. By using convergence technology only one infrastructure needs to be maintained that can control all functions: intrusion detection alarms, temperature control, IP video, etc. which reduces costs and enables easier merging with new technology and software upgrades.

Better compression methods have overcome the initial problems with the heavy bandwidth for transmitting used with IPTV. There are two main formats used: Motion JPEG and MPEG4. The lower bandwidth per video stream of the MPEG4 gives it an advantage over the browser-based MJPEG but it needs a codex or applet for browser Web viewing. In a control center, the virtual matrix allows switching any video stream to any decoder due to decoders connected to all the monitors.

With such technology it seems inevitable that companies will need to consider it in order to keep up with the software of the future. As things stand there are high-security capabilities to videotape at a different frame-per-second speed and to playback or monitor at any other speed. This would mean that video evidence of any crimes, fires, or emergencies, if recorded at low frames-per-second would provide more critical detail for investigators to view. There have been numerous crimes solved by police being able to see high-resolution images from nearby business security cameras.

Tips For Upgrading Your Home Security System With New CCTV Technology

One area of home security system technology that has advanced by leaps and bounds in recent years is CCTV or “closed circuit” TV technology. In fact, it has advanced so fast and at the same time become so affordable that many people with existing home security systems have been left out of this new trend.

What this means is that new aspects can now be added onto your home security systems that you may not have even thought of. For instance, new technologies in disguised miniaturized CCTV cameras now make it possible to far more effectively see whats is going on “inside” your home or business when you are away.

Are your employees ripping you off? Is your wife or best G/F, heaven forbid, romping with other men or even other women while you are away working to keep bread on your families table? How is your baby sitter actually treating your kids while they are entrusted in her care?

The answers to these and many more questions that you may have are all now possible thanks to new super small CCTV cameras that come in any of a number of disguises. Is it a thermostat for your air conditioner on the wall or a new miniature CCTV camera? Only you will know unless you open your mouth.

In fact, you can even have CCTV plugs installed around your home or business that function in the exact same way as a plug for cable television or cable Internet service. If there ever comes a need for you to do some “fact finding”, simply bring in a disguised camera and hook it up.

Don’t worry about having to spend hours looking through video tape on fast forward either. This is because today’s new CCTV systems use a DVD to record on, so you can simply click through it just like you would any other type of DVD or CD.
