There’s much buzz over DVR surveillance systems. With so much information flooding the Internet, it becomes difficult to choose one that’s just right for your small scale or corporate needs. But knowing what’s best for you before you get a system saves you all the trouble, time, and money.

Sorting the CCTV and DVR Surveillance Systems

Non-techie consumers have a difficult time getting the gist of the technical information on home or office surveillance systems. What they want is a system that works best. They want to know what’s going on behind their backs, see who has been dipping fingers into the till, and nab the nanny after proof of her roughshod handling of the toddler.

Consumers also want clear pictures on the monitors, a video playback functionality, access to the home surveillance systems via the Internet, and real-time recording of everything happening in the home or office. While some want to catch the mouse while the cat is away, others need the security of knowing family and workers are safe some intruders. Whether it’s CCTV or DVR surveillance systems, knowledge about these systems is consumer power.

Between the CCTV and DVR surveillance systems, the DVR system is getting all the popular attention for its affordability and flexibility. This system can use the home PC as the nucleus for the system, which knocks off some installation expense. With the CCTV system, the cameras are hooked to a central monitoring system, which comes with the package.

What’s Best for Your Home?

For a small apartment or a mansion, there will be different surveillance solutions for different needs. A small apartment owner would want to know what is going on in the nursery or the bedroom and who is at the door, while the lord of the manor would like to have the vast grounds and all rooms watched.

For a small home or a mansion, the need is for clear images, real time monitoring and recording and safe storage of files. Beyond these parameters, consumers get lost when sorting the information. If you’re looking researching surveillance systems tell the vendor what you need, such as:

* You don’t want playbacks with too much interruption and blurry images. Concerning this, you’re referring to the speed of the frames per second or the rate the capture video can be viewed and you want image images from the different cameras mounted in the different parts of the house or business establishment.

* You don’t need a big storage; you just want something that can store a day’s recording because you’ve heard that small storage space affect the quality of the images. The DVR surveillance systems offer smaller storage space compared to the analog (mechanical) systems.

* You need a small but practical system for your home, something easy to install and upgrade without costing you too much. The system should be able to provide clear images. This is the entire purpose of the system, getting superior images on the monitor.

* You need different cameras for indoor and outdoor surveillance and you want a working combination of flexibility and functionality plus affordability. Be ready with the estimated distances of the cameras to the monitoring station as these will be counted in the cost estimates.

* Ask for the available starter packages for surveillance systems if you are using your PC.

Knowing what to ask from the vendor gives you the edge when you are shopping for CCTV or DVR surveillance systems.

Wireless Home Security Cameras

CCTV systems are now been used in an increasing amount of domestic properties. Domestic CCTV systems offer the house holder an extra level of security and many CCTV installations are now been installed by the end user. Many home owners are buying professional DIY CCTV kits or CCTV packages and cutting out the CCTV installation companies, this often means you can install much better quality components for half the price of what you would pay for an installed system.

Installing your own CCTV system is straight forward and can be done in a number of ways. The easiest method is to use ready made RG59 cables that carry the cameras power and video signal to a CCTV DVR, which in turn is connected to your TV via a BNC to Scart connector. A CCTV DVR will allow you to record more than one camera’s images at the same time directly to an internal hard disk, while adding the time and date. The type of DVR you select for your installation will depend on the number of cameras you require or may need in the future, as standard they range form 4-16 cameras. CCTV DVR’s allow you create a split screen so you can see multiple cameras at once or you can just select the camera you are interested in. If you want the feature to connect your DVR to the Internet to allow remote viewing this too is possible. Configuring your DVR to allow you to see your property across the internet is becoming extremely popular and requires a little IT knowledge to configure the Router, Firewalls and your DVR.

Selecting the type of CCTV camera depends on your budget and the quality you desire. An external camera will have an Infra Red distance, this is the maximum the camera could see in darkness, bare in mind that the rating means there and back as the Infra Red has to reflect back to the camera for the image to be visible. Also its worth noting that IR Cameras don’t work too well if they are just pointing at grass, trees or bushes are these are very absorbent. Cheaper cameras usually have a fixed lens, these are the easiest to install but don’t offer the flexibility of a vari-focal lens camera that allows you to change the focal length. A CCTV cameras resolution is measured in TV lines ie a camera with a 540 TVL sensor will generally have a higher resolution that a camera with a 400TVL CCD image sensor. Although the quality of a CCTV camera depends on more that just the TVL rating, the lens, circuitry and build quality can be more determental. Also the best cameras at night use whats called an ICR filter, this is other wise know as a True Day Night Camera and these cctv cameras generally offer up to a 30% increase in image at night compared to non ICR cameras. Buy your cameras with care from a reputable dedicated CCTV supplier as the quality can vary enormously.

To install a system in your own home firstly work out where you would like to put the cameras and how far these points are from the likely location of the CCTV DVR recorder, work our how much cable you will need before you purchase your CCTV Kit to ensure you will have enough to reach your desired location. You will need a drill with a long drill bit, some ladders and just a little common sense!
