Security Cameras - A Buying Guide

There is a wide variety of security camera choices available today. If you are looking to add surveillance cameras to your home security system, you may be a little overwhelmed by all of the options available. However, with a little research you will be able to find the security cameras that best suit your particular situation.

Whether you are looking for home surveillance cameras or surveillance cameras for your business, you'll want to check out all of the options and make an informed decision.

You'll first want to decide between wired security cameras and wireless security cameras. Both types have their advantages and disadvantages. Wired cameras generally have a more stable connection to the recording device and are more difficult to interrupt. However, they need to be hardwired into your home or office. This usually means that once you've chosen their position, you're stuck with it. Also, it may not be possible to hardwire cameras in all areas. Wireless cameras can be placed almost anywhere and they can be moved quite easily if needed. However, there is a chance that their signal may be disrupted on occasion.

The decision on where to place your cameras is also an important one. Do you want them to record everything that takes place, inside and outside your property? Is there are particular area that is a target for vandalism? Do you want them to act as a visible deterrent to crime or would you rather have them record from a more hidden location? The placement of your cameras will determine a great deal in terms of what types of surveillance cameras you need.

You will also need to determine whether you want black and white surveillance cameras or full colour ones. Black and white cameras are generally less expensive than full colour security cameras. They are good for general use and can see a decent amount of detail. Black and white cameras usually work better at night than colour cameras. Colour cameras are more helpful at determining small details such as the shirt colour of someone that has broken into your property. These require a light source to function however. Using colour cameras in the dark will result in recording nothing but a black screen. Some cameras are able to switch between colour and black and white depending on lighting conditions.

Also note that if you are planning on recording in low light situations, you need to keep this in mind when installing your surveillance cameras. Not all security cameras see well in the dark. An easy way to fix this problem and provide your property with extra security is to install lighting in areas where your surveillance cameras are filming. Not only will this give you higher quality footage, but it will also deter criminals who often like to work under the cover of darkness. There are also infrared security cameras for shooting in dark situations. These may be helpful if you have no choice but to film in a dark area. Some surveillance cameras have a "night mode" that allows them to automatically switch to infrared shooting when necessary.

Once you have decided where you are going to place your security cameras and whether or not you would like to shoot in colour or black and white, you will need to choose the type of camera you would like to use. Two of the most popular kinds of security cameras are dome surveillance cameras and bullet surveillance cameras.

Dome cameras are one of the most common and most popular types of surveillance cameras. They usually come in either black and or white and are cameras surrounded by a domed covering. This dome is useful for many reasons. First of all, it is often difficult for someone looking at the security camera to determine which way it is pointing. This allows you to protect a larger area since no one will know exactly what you are filming. The dome can also provide protection for the camera itself. The downside is that these surveillance cameras do not usually work well in low light situations.

Bullet cameras are thin, cylindrical security cameras. They are usually very cost effective and their design makes them a great crime deterrent. Bullet cameras can also be equipped with infrared abilities in order to allow them to record at night and in low light conditions. However, these cameras are not usually considered vandal proof on their own. They should be placed in locations where they cannot be easily tampered with.

As you can see, there are a lot of important decisions to make when buying home security cameras or business security cameras. By spending some time considering all of the factors involved and making an informed choice, you'll find that your surveillance cameras will help you effectively and efficiently reduce and prevent crime.

IP Cameras - A New Booming Market

What is a IP Network Camera?

In simplest terms, an IP Camera is a stand-alone device that transmits audio and video through a standard CAT5 Network Cable. It has a built-in web server which allows the camera to run individually without a PC having to be connected. It also allows you to view the audio and video by connecting directly to the camera with your internet browser without any software being installed. This allows you access the camera from any location, even over the Internet.

IP cameras have many advantages over tradition CCTV security cameras. Some of these features include wireless connectivity, the ability to view video remotely over the Internet, the ability to record to a remote location and lower cost.

Advanced features of Network Cameras can offer added security for certain applications. These features include, Motion Detection, Pan/Tilt/Zoom, Infrared, Analog Output and Two-way Audio.

Lets discuss these features in greater detail.

Motion Detection

Some Network Cameras come with a feature called Motion Detection. Hot-Spots can be setup within the video frame to detect motion. Once motion is detected, the camera will begin recording or generate a snapshot which can be Emailed or sent to a web server via FTP of the detected motion. Snapshots can also be sent of images prior to the motion and after the motion.

Pan/Tilt/Zoom

Having the ability to Pan and Tilt adds greater security if you have a large viewing area. Once logged into a Network Camera with Pan and Tilt capabilities, controls appear next to your video allowing you to move the camera left, right, up and down. The controls can be used even over the Internet.

Along with the Pan and Tilt feature, some cameras come with Zoom. Zooming is also handy when a greater detail of video is needed. Network Cameras can come with two methods of Zooming: Optical and Digital. One is called Digital Zoom.

Digital Zoom discards pixels around the edge of the video fitting the remaining pixels into the same space to give the appearance of Zooming in. This comes with the expense of resolution and causes the Zoomed image to look very pixilated.

A post was made on the NetworkCameraReviews.com forums that addresses the differences between digital zoom and optical zoom. Click here to view the post.

Infrared

When needing to view video in the dark, Infrared is the way to go. Cameras can come with a built-in IR (Infrared) lens or the ability for an add-on IR lens to be equipped. Infrared is a wave of light that is outside of the visible part of the color spectrum. Infrared illuminators shine this wave of light which the lens picks up.

Analog Output

Some cameras come with an Analog Output to configure your camera to be notified of opened doors, alarms, or other events. Once notified of these events, the camera will start taking snapshots or video.

Two-way Audio

A Majority of cameras have audio built-in to the camera. This allows you to hear audio along with the video the camera displays. Some cameras come with Two-Way Audio.

There are two types of Two-Way Audio. One is a Full-Duplex Two-Way Audio that allows the user at the PC to hear audio from the camera and also speak back to the camera and have audio come out of the camera itself. Some cameras have a speaker port on the back to plug in external speakers which will give off the audio. The second type is a Two-Way Audio within the camera itself. The camera will pickup audio and send the audio to the speakers hookedup to the camera.

In the next article we will be addressing how IP cameras work.

Hidden Cameras - Peace of Mind and Security

Sometimes, you want security, but don't want to advertise to the world that you have it. Take security cameras, for example. The security provided by a camera recording footage in case of a crime makes good sense as a wise investment, especially if your business is one that might be prone to these sorts of incidents. But if your security cameras are in conspicuous places, criminals will know where they are to neutralize them, or how to hide their faces from them. A security camera works best when it's a silent observer, and the best way to get this effect is to use hidden cameras.

By using hidden cameras for your security surveillance, you're not only protecting your investment in your business, but your investment in the cameras as well. The more discreet your cameras are, the less likely it will be that they will be found and sabotaged by would-be thieves. By keeping them out of sight, you'll make sure that they'll stay intact so that they can record everything that happens in the room. Nobody wants for something bad to happen. But there's always the possibility of the worst-case scenario, and it's always better to be prepared than not.

Hiding your security cameras can also have a secondary benefit. If your hidden cameras blend into the decor of your business, then your business will boast a better aesthetic. The truth is that, as useful as security cameras are, nobody wants to see them. Seeing a security camera is a reminder that something bad could happen in that room. Using a hidden camera will give you all of the security surveillance that you need without filling your customers' heads with thoughts of crime scene photographs and grim news stories. Instead, they'll be able to concentrate on whatever it is that your business is selling.

Security cameras have nearly become a business necessity in today's world. But just because you need them doesn't mean that you have to build your business around them. Instead, use hidden cameras that will allow you to run your business as though you didn't need them at all. In the long run, you'll have the peace of mind that comes with knowing that you have security measures in place, while your customers will have the peace of mind that comes with feeling safe in a business environment. It's amazing that so much peace can come with something so small.




If you are looking for hidden cameras for your business, you will find many at TBO-TECH Hidden Pinhole Cameras. You will have a large variety to choose from that will be sure to blend in with your business' decor.

A Better Type of CCTV

IP CCTV is a form of CCTV that for many companies and individuals will prove to be a better system and will have a range of unique benefits. For those looking for the best possible security and surveillance solution for their home or business then, IP CCTV should be a consideration.

Standing for 'Internet Protocol' (and of course 'Closed Circuit Television), IP CCTV is a type of CCTV that does away with the need for lots of different cables by instead transmitting the data wirelessly to be picked up by a range of devices that have been enabled. This has many benefits, if only for the lack of wires everywhere. Of course lots of wires and cables is never a good thing at the best of times as they are easy to trip over, don't look attractive, and can also cause electric shocks and other problems if they are cut or damaged.

At the same time IP CCTV this way saves you from having to organise your CCTV set up around where your cables can reach. Normally cables might mean setting up your CCTV in perhaps less than optimum positions, or having to have serious work done on your premises in order to run cables through the wall. At the same time this can help to save you money on the work and on the cables themselves, and it also means there's less to go wrong at a later date making set up and maintenance much simpler and easier.

Meanwhile this internet connection also means you can get your CCTV on a range of devices including laptops and desktop PCs. This means that you can watch your premises while you are away from work, and this is great for peace of mind, and also for preventing problems.

IP CCTV also has other features in many cases. For example, often the transmission on the cameras is two way. This then means that the cameras allow you to actually speak through them. Should you see or hear something then, you can then respond - warding away trespassers or advising staff in your absence creating a truly 'Big Brother' like presence. Many IP CCTV cameras include VoIP which means that the device can also communicate with other services such as the phone line - meaning that it can work along with face recognition and motion sensing to actually call you and alert you of trespassers on your premises even when you're miles away. Of course the implications here in terms of keeping your property safe are far reaching. This is achieved using something called 'video analytics' which is catching on and more and more allowing devices to analyse what they're seeing in real time and respond accordingly. Other services include being able to alter the frame rate and definition, and adding password protection etc.

When choosing your device you will need to pick between a 'centralised' or 'decentralised' camera. This refers to the cameras either using a central network video recorder for handling the video and alarm, or having built in functions and their own storage.




When you know which you need you can get any kind of CCTV cameras at these links including IP CCTV.

Analog Vs Digital Resolution - TV Lines (TVL) Vs Pixels Explained

One of the most confusing and difficult topics in the CCTV world is resolution. Most of us have digital cameras or video camcorders and have heard the term megapixel used as the most common comparison in resolution between various makes and models. We are also aware that a larger number means better picture quality, but many people do not know why. In the CCTV security camera world, though, most cameras are still analog and their resolution is measured differently from what we are used to.

Analog Resolution

When measuring analog resolution, a TV line does not have a defined number of individual pixels. Instead, the term "TV lines" refers to the number of discernible horizontal or vertical lines on the screen. Analog security cameras are measured in Analog TV Lines, and most of them have between 420 and 580. The higher number of TV Lines, the more information captured. These types of cameras connect to a security DVR or CCTV VCR via coaxial video cable.

Digital Resolution

A pixel is the smallest element of a digital image. We have all zoomed too far into a picture from a website and seen the image go from clear to a bunch of colored squares - each one of those squares is an individual pixel. A megapixel (MP) is 1 million pixels, and is a specific measurement for digital resolution that encompasses the area of the output video.

Example: If a camera outputs a signal that is 1280x1024 pixels, it is shooting at a megapixel resolution of 1280 x 1024 = 1,310,720 pixels = 1.3 Megapixels (MP).

The most common type of digital security cameras are IP Cameras. These, like your digital camera at home, use strictly digital resolution. They utilize a network connection to either act as a standalone device or connect to a network-based DVR (Digital Video Recorder) or NVR (Network Video Recorder). IP Cameras have fixed resolutions and are now approaching, and in several cases exceeding, 1 megapixel in resolution, on average. Many of these cameras also support POE (Power Over Ethernet), which allows them to be powered by the Ethernet cable used for network connectivity, and PTZ (Pan Tilt Zoom), allowing for remote control of the pan, tilt and zoom features, if applicable.

More and more industry installers and professionals are moving to network-based CCTV equipment because of the flexibility and expandability that it allows. Massive remotely-viewable security camera infrastructures are replacing old, out dated analog systems at an increasing rate and will soon become the preferred industry solution.

Network Security Camera and CCTV Comparison

The benefits of a network security camera system extend beyond the functionality that an analog security camera system can provide. The advantages include remote accessibility, high image quality, even management and intelligent video capabilities, easy integration possibilities and better scalability, flexibility and cost-effectiveness.

A network system allows multiple users to access, configure, view live and recorded video at anytime from anywhere in the world with an internet connection. This allows for a third-party company, such as a security firm, to provide additional services such as diagnosing problems or monitoring the system. With an analog CCTV system, you would have to be at the monitoring site to view and manage video, and remote video access would require installation of additional equipment such as a video encoder or a network digital video recorder (DVR). A DVR is the digital version of a video cassette recorder.

When there is a need for high quality images to identify people's faces or detailed objects, network security cameras with progressive scan and megapixel technologies can deliver better image quality and higher resolution than an analog CCTV camera. Image quality is also better retained in a network security camera system than an analog camera system. With analog systems that use DVR, there has to be conversions from analog to digital in the camera, then converted back to analog to transport through the analog cables, then again to digital to be recorded. With each conversion the image quality is degraded. Analog video signals also become weaker the more cabling it has to travel through. In a fully digital system, images are digitized once in the network camera and stay digital so there is minimal degradation.

All network security products are built to an open standard can be integrated with computers and Ethernet-based devices and software. Also, as the video system grows, the scalability and flexibility of a network security system comes in extremely handy. Any number of cameras and devices can be added to the system minimal invasion to the infrastructure already in place. In an analog system, each camera needs a cable running directly from the security camera to the monitoring station. Network cameras can be placed and networked or removed from virtually anywhere. For this reason, once the network system is already in place, it is much more cost effective than an analog system on the basis of the flexibility alone. Network cables and wireless devices are also cheaper than traditional cabling for analog systems.
