With so many choices of surveillance cameras in the market, it is easy for a consumer to get overwhelmed in choosing the best security camera for their system needs. No matter what type of surveillance application you are installing, there are some basic things that all consumers should consider in order to make a good choice. This will be the first of a series of articles to help guide a non-technical person that is researching the purchase of a surveillance system. The main topic for this first article of the series is security camera resolution.

It is important to know what resolution means when shopping for a surveillance camera. CCTV cameras have a resolution range from 330 TVL (television lines) to 600 TVL. For color resolution, CCTV cameras max out at 560 lines, however you can get black and white CCTV surveillance cameras in 600 TVL. IP security cameras are now available in much higher resolution, up to 5 megapixels. What does this mean?

In the United States, regular TV transmission (not high definition) displays 480 lines of resolution. So it is possible to purchase CCTV cameras that can record equal to or greater resolution than TV. Obviously the higher the resolution of the camera that you choose, the more detail you will see in your surveillance video. High definition television (HDTV) displays either 1080 or 720 lines of resolution depending on the channel and the type of HDTV that you have. In order to get higher resolution from surveillance cameras, the only choice is IP based megapixel cameras, which connect over an IP network instead of a closed circuit. Generally, IP mega-pixel cameras are much more expensive than CCTV cameras. For high end applications that demand ultra-high resolution, megapixel cameras can capture surveillance video at more than twice the resolution of high definition television.

Some people that are shopping for a security camera are unrealistic (because of their lack of experience) about what a surveillance camera can capture (especially CCTV cameras). I will go into more detail about lens types and sizes in the next article in this series. I must touch on it briefly now as it is so closely related to resolution. For this example, we will use a 3.6mm lens which gives you about a 90 degree field of view outward from the lens. Some people think that if you take a 480 lines of resolution camera with a 3.6mm lens that you will be able to get a clear picture both of an object that is 20 feet away and an object that is 80 feet away. This is not true. While the 3.6mm lens will easily pick up the object in detail at 20 feet away, it cannot pick it up at 80 feet away also with the same 3.6mm lens. In order to pick up the object at the further distance, you have to either use a larger lens that would make the image appear more close up or use a high end megapixel camera that would allow the operator to zoom in digitally without distorting the picture. Digital zoom is possible with high end megapixel cameras, but not with normal resolution CCTV cameras. Because of the huge price difference between CCTV and IP mega-pixel cameras, a lot of times it makes sense to add additional CCTV cameras instead of upgrading to megapixel cameras. This will lead us into the next article which will be about understanding and choosing the right camera lens.

With home invasion at almost epidemic levels and business and home burglaries on the rise maybe we need to look past prevention tools and evaluate having a hidden camera to catch the bad guys. Here we look at a couple of ideas that will catch them on video so law enforcement can apprehend them.

The first idea is a 4 channel USB DVR system. It is a system that turns your home or office computer into a powerful, worldwide video surveillance system in the blink of an eye. It has 4 indoor outdoor cameras, the cable for each and the USB DVR a piece of hardware that does the work.

This system gives you great flexibility to record four indoor and outdoor areas or a combination of both. The system is easy to install and can be done in minutes. If you prefer a wireless system, that is available too.

Another idea is a new generation of hidden camera that operates similar to a digital camera with images recorded on an 8 GB SD card. The camera is aimed where you want to record and using the remote start recording. Playback is done with an RCA cable to your TV or removing the SD card and inserting it in your computer.

These hidden cameras come disguised as common household items that are impossible to detect the camera hidden inside. Items like wall clocks, desk lamps, alarm clocks, boom boxes, tower fans and more house the camera and DVR. Almost all of these items are actual functioning products making the deception more realistic.

Another idea is the IP camera. They plug directly into your computer or DVR using an IP address to transmit video through a network using Ethernet/CAT5 cable. Set-up and viewing software comes with the camera and can support up to 16 cameras.

Need to see your business from home? Your vacation home from your primary residence? This is the tool for you.

These are perfect surveillance tools for home, office or business. Surveillance professionals in law enforcement and Private Investigators love them because of their discreet recording capabilities.

When you need to find out what is going on at your home or business the easiest, best and most cost effective way to do it is with an all inclusive Hidden Spy Camera with built in DVR, IP camera or USB DVR System.

After all you can’t be there 24/7 so let these technological wonders be another set of eyes for you.

IP Cameras are increasingly becoming a necessary part of any home or business security system. Bad people need to know that they are being watched. That way, they are less likely to commit their heinous crimes. But sometimes bad guys will disable video cameras. What is to be done about that problem? Well, a bullet camera is one solution. Its small enough to be hidden in the palm of your hand or in very small crevices around your property. So the thugs may know theyre being watched, but they wont know from where. And these cameras work well even in low-light situations.

Better yet, the cameras no longer hook up to bulky, easy to steal, tape recorders. The new IP cameras stream your surveillance footage to anywhere on the earth that you want, and youll now have a permanent record of everything that happens on your property. Not sure if the hoodlums bothering you are the same ones who were at it five years ago? Just pull up the video on your computer. Or put together a shaming video of the highlights of idiots whove vandalized your store. Get your revenge the legal way by putting these criminals where they deserve to be.

First of all, lets take a look at IP camera definition. IP camera (Internet Protocol Camera) is utilized in local and distributed surveillance systems and can transmit/receive megapixel video information via the Internet and local computer network. This enables the operator to view, manage and control this megapixel IP-device using a standard web browser or professional video management software (like VMS) from different monitoring posts.
An IP-camera (also called network camera) has the following components:
1. Lens.
2. Image sensor, which allows camera to generate high-quality megapixel images with high resolution.
3. Processor, providing video processing, compression, video analysis etc.
4. Memory for storing special firmware.
Megapixel IP-camera can be configured to transmit simultaneously several video streams, to send video for viewing in different modes and to set up camera responding upon receiving alarm signals or motion detection.

Advantages of megapixel IP-camera

Higher Video Resolution and Image Detail
To understand the difference between standard analog camera and megapixel IP-camera lets compare the effective pixels each camera can transmit:
A standard resolution analog camera with 380TVL transmits images with 480×380 pix. resolution, or 182,400 pix. that is roughly 1/5 of a megapixel!
A high resolution analog camera with 520TVL can generate images with 480×520 pix. resolution that is equal to 249,600 pix. of around 1/3 of a megapixel.
For example, a 2 megapixel camera produces 1600×1200 pix. images that is equal to 1.920,000 pix.
Progressive Scan – No Interlace Distortion of Moving Objects
Most of presented video recorders) often face some difficulties when recording fast moving objects resulting in comb effect of recording footage. Modern network cameras feature Progressive Scan technology that allows the camera to produce crisp images.
Easy Installation and Reduced Costs
If your premises have existing computer networks, so you can easily install IP-camera as a part of this network without any difficulties. Due to PoE support, megapixel IP-camera can be powered by the same cable that transmits video streams. In many cases, it reduces installation time of IP-camera, as well as eliminates the cost of a separate power supply wires. Due to the audio I/O, megapixel camera can provide two-way audio communication between the operator and the application.

Summary

As you can see, IP-camera usage has a number of advantages with excellent picture quality, easy installation and set of viewing modes among them. However, modern network camera also has some disadvantages that include greater complexity and bandwidth demands.
