Security Camera Systems and Digital Video Recorders

Closed Circuit Television (CCTV) or Video Surveillance Systems are common terms used to describe some type of camera and recording device implemented to deter or catch a criminal. There are three fundamentals that you should keep in mind when looking to implement a Video Surveillance Systems. These three principals will also guide you in what type of equipment is needed for your circumstance and they are Detection discovery of events happening within the field of view,  Recognition –acknowledge exactly what the events are taking place in the field of view and Identification – determine who or what is involved in the events.   

 Camera Types:

These cameras can come with all type of options and can use a large variety of lens for the most difficult lighting conditions. You can use these types of cameras outside but they will require some type of protective housing preferably with a heater and blower to protect the electronics of the camera.

Day / Night & Low Light Security Cameras: These cameras have a wide range of things to consider when selecting the right security camera for your application. When you are faced with a low light application there is one specification that you need to pay very close attention to and that is the camera lumen (LUX) rating.

Infrared Security Cameras: Night vision cameras combine use infrared illuminates for night time surveillance will allow a color picture to switch to black and white when used with the IR LED’s at night. There is a built-in light sensor that determines when light source has changed enough for the camera to operate in night mode. This cameras are good at viewing objects at close range of where the field of view is limited.


Vandal Proof & Weather Proof Security Cameras: These cameras consist of a security camera inside of a vandal resistant housing, making themMaryland_Baltimore_Harford Security Cameras perfect for areas where they could be damaged by people trying to take out the camera view.

Theses cameras are designed for the sole purpose to capture license plates, during rain, snow, glaring high beams, fast moving vehicles, trucks, cars, vans and they work great.

Network IP and High Definition Cameras: Network IP cameras can be connected to your network but we offer caution in doing this because of bandwidth limitations. Before you connect a camera to your network I would diffidently consult your IT Administrator to make sure you don’t crash the network. Most applications we are involved using these types of cameras we end up installing a separate network for security reasons and because of the band width issues especially in older networks. These cameras are getting better every year by producing High Definition 1080p Quality Video in a variety of housings and mounts. These cameras take video surveillance into a whole new world. Where it would take three to four cameras to cover and area it now can only take one camera. This saves time, money and produces incredible video where you can actually make someone out in the playback.   

Digital Video Recorders and Network Video Recorders:  
Digital Video Recorders: Digital Video Recorder (DVR) will continuously record security camera video onto a hard drive for playback with a variety of search features such as date/time, event or alarm. With a built in multiplexer that allows simultaneous recording of multiple security cameras on to one hard drive. DVR’s come in multiple camera channel configuration as well as different size hard drives to store video. There are many factors that go into calculating the size hard drive needed for your application so no one application is the same as the other.
