Everything You Need To Know Before Buying Security Cameras & Systems

HD VIDEO IS SUPERIOR

There is no comparison between HD video and older analog technology. HD video is much higher resolution and displays far better detail and clarity. In fact, you can expect our HD CCTV security cameras to be at least 3-5 times sharper than standard analog cameras. This is because HD cameras are measured in megapixels. Each megapixel comprises 1 million pixels or dots on a screen. 1MP and above is considered high definition which is the equivalent of a 720p digital broadcast signal. Full HD television is broadcasted at 2MP or 1080P. A 4K Ultra HD CCTV security system video broadcast is equivalent to 8MP. The higher the megapixel count, the sharper the image.

One great benefit of HD cameras is that you can digitally zoom or blow up an HD picture and the integrity of the image will remain largely intact rather than appearing pixelated or blurry like the older analog CCTV security cameras.

DVR VERSUS NVR

Want to buy security cameras? There are 2 types of HD security camera technologies; HD over Coax and Internet Protocol (IP). A recorder that supports HD over coaxial cable is called a digital video recorder (DVR). IP cameras connect to an (NVR) network video recorder using Ethernet or network cable. Both DVR and NVR units provide the same basic functionality. Either can be used to view live or recorded video and also to view your cameras remotely on a smartphone, tablet, or computer. One of the main differences is the type of cable used to connect the cameras. It is also important to note that HD over Coax recorders are backward compatible with older analog cameras. In other words, you can use both HD CCTV security cameras as well as any existing analog cameras with our HD over Coax digital video recorders.

IP NETWORK SYSTEMS

IP cameras and systems are the new industry standard. We offer 2 IP camera product lines - the Green-line and Blue-line. You should always match products with the same color code for the best compatibility and overall user experience. Our Network Video Recorders are able to display Ultra HD images up to 8MP or 4K. IP cameras are run using CAT5, CAT5e, or CAT6 Ethernet cable. All of our IP cameras are PoE (Power over Ethernet) meaning that both power and video are transmitted over a single cable for very simple installation. Standard IP cameras can be run up to 325ft. We offer additional CCTV security system hardware such as repeaters and switches for customers who require further cabling. A unique feature of our Green-line (SureVisionTM) IP CCTV security camera line is the ability to transmit both power and video over 1,000ft using pure copper Ethernet cable.

HD OVER COAX SYSTEMS

HD over Coax cameras are run using traditional coax cable with BNC video connectors. Our Digital Video Recorders can also produce ultra HD images up to 8MP or 4K and are also compatible with older analog cameras. The most common type of cable used is RG59 Siamese cable. The term Siamese means there are actually 2 cables (power and video) running side by side that can be pulled apart. This is important because HD over Coax cameras are not powered by the recorder. Rather, HD over Coax cameras can be powered using an individual power adapter or a multiple output power when running multiple CCTV security cameras. HD over Coax is extremely beneficial when a customer has existing analog infrastructure in place and wants to also add HD cameras. So, if you want to buy new security cameras, think of your upgrade options. Another benefit of HD over Coax is that video can be transmitted distances well over 1000ft away. Our digital video recorders support all of the HD over coax technologies.

CAMERAS

 

We carry many different styles of cameras. A lot of people like the bullet style cameras due to their sleek housing. Other people prefer a dome style for their discreet, low profile, and vandal-resistant design. A large majority of the cameras we offer are fully weatherproof for indoor or outdoor use - perfect for a complete CCTV security system for any property. The size of the camera lens will determine its viewing angle. Our widest lens size is 2.8mm and will produce a 110 degree super wide-angle, which is good for covering the entire immediate perimeter. Our most popular lens size is the 3.6mm which offers a 90-degree wide-angle. Customers like wide-angle CCTV security cameras because they offer the most bang for their buck. However, if you need to focus on an object that is much further away, then you will require a more powerful lens such as 8mm, 12mm, or even a 50mm lens for good close up images of objects that are over 100ft or even 200ft away. Many of these cameras offer a varifocal lens that you can adjust to achieve the perfect angle. Better yet, many of the varifocal cameras have a motorized lens so you can simply adjust the angle directly from your recorder or remote device. In short, there is always going to be a compromise between the width of the angle and the distance you can see. The perfect solution may sometimes be a combination of wide-angle and varifocal CCTV security cameras.

WIRELESS CAMERA SYSTEMS

Wireless security camera systems

Wireless cameras have also become popular with the release of the many consumer WiFi gadgets available today. These cameras are often limited in terms of selection, clarity, reliability, and function. It is important to understand that the term “wireless” mainly applies to video transmission. Many of these consumer devices are battery-powered. We do not offer battery-powered cameras because their batteries eventually need to be replaced or recharged. As a result, they are much less reliable. We do offer professional-grade wireless IP camera systems that plug in with a single PoE cable for both power and video transmission. That makes it easier to mount these CCTV security cameras in places that might otherwise be inaccessible to a power outlet.

Another consideration is that wireless cameras can be subject to interference or loss of WiFi signal. Our wireless cameras can transmit a highly reliable video signal up to 75 ft. We recommend hardwired cameras for applications with further distances or structures that prohibit an adequate WiFi signal.

STORING VIDEO FOOTAGE

Another consideration when designing a CCTV security system is storage. Most business and property owners choose to store their captured video footage for 7-10 days. All of our recorders have internal hard drives inside the units where the video is stored. We only use commercial-grade hard drives for the best durability. The higher resolution CCTV security cameras will require more storage simply because they consume more data. This is why we offer customers the ability to increase the size of their hard drive to meet their exact storage needs. A majority of customers set their recorder to record only when motion is detected in order to save hard drive space. For example, a 4 camera HD recorder with a 1TB hard drive can record continuous video at 4MP for up to 7 days. If the same recorder is set only to record on a schedule, or when motion is detected, the storage time will increase significantly. Less expensive video recorders only have space for a single hard drive. Many of the units we carry have multiple hard drive bays to accommodate more video storage from CCTV security camera footage if and when required.
