Adding IP Cameras to an NVR or DVR

Although there is more to learn than just a simple web page this page gives do-it-yourselfers a great brush up on the basics of setting up IP cameras. There are many more skills to learn that are network and video system equipment specific. The basic are the same for all IP camera setups.

  1. IP camera power setup. This is usually a POE switch, individual camera power or in some case the DVR or NVR has a POE switch built in.

  2. Network configuration. Basic networking skills are a necessity

  3. DVR or NVR network configuration

  4. IP Camera network configuration

  5. IP camera registration.

Users and Groups for security cameras

It is possible to set up users and groups for most security camera systems. Setting up users and groups allows the administrator the ability to manage functions and viewing. For example, a manager may want some users to only be able to view live footage or only be able to see some of the cameras. It is important to make sure that very few people have access to administrator privileges. Creating differing authority levels will allow administrators to grant access without compromising security of your video surveillance system.

Fiber Optics Color Code

There is an industry color code standards for fibers optics as laid out by the Fiber Optics Association, Inc. This helps low voltage contractors and network engineers figure out which type of fibers, cables and connectors they are using. There are many types of fiber optic cables including varities of: multimode 50/125, multimode 62.5/125 and singlemode fibers. The color code helps project managers ensure that the projects are done correctly. It also helps with additions and changes in the future. As mentioned before communication fiber optics have 3 main components: the fiber, the cable and the connector. Below is a brief overview of the color codes.

Black Cable – outdoor fiber optics fiber

Yellow Cable – indoor single mode fiber

Orange, Aqua Slate and Green Cable – indoor Multimode fiber

Beige, Black and Aqua connector – multimode connector

Blue and Green Connector – singlemode connector 

Covert Cameras and their Advantages

Covert surveillance equipment serves an important role in security. Although a traditional security camera system is the basis of achieving the peace of mind security provides, these systems aren’t always enough or appropriate. There are many scenarios where a conspicuous security camera placement will only deter people from doing inappropriate things in the areas they know they are being monitored.

Covert surveillance equipment, on the other hand, gives businesses the added ability to maintain surveillance inconspicuously. Covert security cameras are hidden from plain view and are often used to supplement traditional security camera systems. Here are a few scenarios where hidden cameras are commonly used.

  • Discreetly monitoring a nanny or babysitter

  • Capturing evidence of theft by friends, family, or roommates

  • Confirming and preventing employee theft

  • Identifying theft by workers or contractors

  • Confirming suspected drug use

  • Capturing destructive animal behavior

  • Recording acts of vandalism

  • Enhancing current security camera systems

 

Budget IP Cameras, Good Idea?

You get what you pay for…

There is no IP surveillance camera that is reliable, with good picture quality and processing speed that is also inexpensive. The camera that is “cheap” will be deficient in one of these four categories: reliability, picture quality, light processing and processing speed.

IP Video Camera Reliability – there are many parts to a camera and not all parts are created equal. All “budget” cameras use cheap components to lower the price. Lens, processor, NIC, IR LEDs, housing and mounts are all parts that can be “cheapened” to meet pricing constraints. With cheap parts these cameras with physically break and/or not be accessible on the network when you need them the most.

IP Video Camera Picture Quality – There is more to picture quality than just resolution. Things like light response, frames per second, shutter speed, day/night mode, IR correction, compression, WDR. Budget cameras will usually not perform well in one or more of these categories. A budget camera may have a great picture when things are not moving but will often be unusable when the subject is moving. Nighttime video quality also lacks with budget cameras.

IP Video Camera Light Processing – High end cameras will be able to represent colors regardless of light source (day). Budget cameras are deficient in this ability and images may appear white out. During the night budget cameras with either under or over represent IR light causing a white out image or no image at all.

IP Video Camera Processing Speed – All video cameras need a processor to convert an image from electrical to digital and vise versa. Cheap processors will result in a “hung” camera meaning that it will not response to access requests and will require a hard reset. Often a camera will market all the bells and whistles be forget to mention the camera is not equipped with a processor that can continuously handles the needs of the cameras processes.

 The Bottom Line – “budget” cameras work well as a deterrent to crime but will often produce a recorded image that that is lacking. I find budget cameras over promise and under deliver every time.

Do Coaxial Cables Deteriorate?

Coaxial cable is more susceptible to damage when compared with other cable types like category cables and power cables. Your need to understand how coaxial cables are made it order to understand how they can be damaged. Coaxial cables have 4 parts (from the inside out): the inner copper core, insulator, metallic shield, and plastic jacket. There are four things that damage a coaxial cable: physical, water, heat and connector.

Physical damage – coaxial cables should be handled with care. Overly bending and smashing a coaxial cable can cause damage to core which will affect the transmission of a signal.  

Water damage – coaxial cables are not waterproof. Water in or on cables can cause changes in video quality. Water can also damage the connectors.

Heat Damage – coaxial cable susceptible to heat damage. The interior insulator can warp causing loss of video quality.

Connector Damage – Connectors can go bad from constant use. The connect itself can be dislodged from the cable. Even oxidation can cause video quality issues.

Camera fail-over for security cameras

There are many types of security camera fail-over solutions for cameras. Security camera fail-over means that video camera footage will be recorded even if the main recording method fails. Local and offsite solutions are the main choices available for security camera footage fail-over. When deciding to use local solutions the options include: DVR, NVR, servers, and SD cards. Usually local security camera fail over are the main method of video recording but can be used as a fail-over or backup. DVR usually work with Analog cameras. NVR work with network cameras. Servers are a high-end solutions for network cameras. Offsite backups include: cloud storage and offsite server backups. Cloud storage solutions usually use a third party server (ie amazon, DNS servers). Offsite servers are simply servers that are installed at a second location.   

Fixed Dome Security Cameras

There are many types of security cameras. Fixed dome cameras are a popular choice for many applications including: warehouse security cameras, residential security cameras, building management security cameras, garage security cameras, wireless security cameras, HD security cameras, IP security cameras, grocery store security cameras, commercial security cameras, enterprise security cameras, convenience store security cameras, license plate reader, driveway gate security camera, pedestrian gate security cameras, parking lot security camera and mega pixel security cameras. A fix dome security camera is a reliable choice and are more subtle when compared to a box camera or bullet camera. The versatility of fixed dome cameras extends to many types of accessories making dome cameras a great choice for any application.
