Guide To Selecting Network Video Recorders

January 28, 2011 by Nathan Miloszewski

QNAP VS-2004 Pro NVRA Network video recorder (NVR) is a piece of hardware that allows you to properly manage, record, store, and view IP surveillance video. 

They differ from PC server based systems in that they are standalone, plug-and-play systems designed only for IP video tasks.  For more on NVR vs. PC Servers check out this post here.

This post however is a general guide to selecting an NVR and the questions you should ask yourself before making a decision.

How To Select an IP Camera Lens

January 27, 2011 by Nathan Miloszewski

There are several elements that affect an IP camera’s image quality and field of view but the one component that is affected first, the piece that is in the first line of approach for a source of illuminance is:  The IP camera’s lens.

IP camera lenses dutifully perform several key funtions:

  • Defining the field of view:  Defining how much detail and how broad the scope of a scene will be captured and ultimately, displayed.
  • Controlling the amount of light:  Controls how much light gets passed to the image sensor so that an image has the proper exposure.
  • Focusing:  Maintain proper focus by adjusting elements within the lens assembly or, by adjusting the distance between the lens assembly and the image sensor.

When selecting an IP camera lens the field of view that you need or desire for you application will determine the type of lens you select.

There are (3) field of view types and (3) main types of lenses.

Best Practices for IP Video Management

January 21, 2011 by Nathan Miloszewski

My recent posts on IP Video Management turned out be 7-part series.  Who knew it was such a fascinating topic to warrant such length, right?  If you gained anything at all from this long run it should at least be that there is a lot to consider with these systems.

And that’s because IP video management is a highly important component of your IP surveillance system.  It is your window to the world in front of your cameras.  Controls, configuration, video search, and live monitoring and recording are all done from this single interface.

To sum everything up, below is a condensed list of best practices to follow to make the right selection for your application.

How to Integrate IP Video Management Into Your Business

January 17, 2011 by Nathan Miloszewski

An advantage of network based IP cameras is the ability to monitor a range of business activities from:

  • Transactions
  • Employee and customer behavior
  • Monitor restricted access entry/exits
  • Manage your building’s utilities and fire alarm system

This can be done by customizing an IP video management system using an application programming interface (API) to integrate IP video into your other systems.  This is a way to further trigger alarms, recordings, and alerts by using information from other systems a business may be using such as:

  • Point of Sale (PoS)
  • Access Control
  • Building Management
  • Industrial Control Systems
  • Radio Frequency Identification

IP Video Management – Input / Output Ports

January 10, 2011 by Nathan Miloszewski

To provide more insight into the event management features of an IP video management system a post was dedicated to video motion detection and this one will detail an integrated feature that completes the circuit of responding to triggered events.

Input and output ports (I/O ports) that are built into IP cameras and video servers are used to connect to other devices in an IP surveillance system

These devices can be programmed to the users specifications to provide a response when, for example, motion is detected or the camera has been tampered with.

In the picture to the right you’ll notice that the Sony SNC-P1 Fixed IP Camera, for example, has a bank of (4) I/O ports.

Video Motion Detection – Triage for IP Video Recording

January 7, 2011 by Nathan Miloszewski

Responding to disasters or emergency medical situations requires triage — the process of determining the priority of treating patients based on the severity of their condition.

Video motion detection employs a similar process in that it prioritizes only the important events and area’s of a camera’s view that you specify to be included or excluded for motion detection.

By prioritizing video recordings, video motion detection (VMD) saves on storage space and bandwidth by not having to record everything making searching for occurences easier as well.

IP Video Management Features – Event Management

January 4, 2011 by Nathan Miloszewski

Moving along in this IP Video Management series, event management is responding to events that have been triggered by built-in features of IP cameras, video servers, or intelligent monitoring software.

An event can be scheduled or triggered and once one has occured you can automatically program alerts and notifications to be sent to cell phones, via email, or even pop-up windows on a computer screen.

One of the most important functions of event managment is saving bandwidth and storage space.  That is, video will not be needlessly viewed or recorded unless an event has happened. 

Further, you don’t have to worry about constantly monitoring your IP camera surveillance – You will be notified if something happens.

There are several ways an event can be triggered and there are many options for setting up the responses.

IP Video Management Features – Recording and Viewing

December 22, 2010 by Nathan Miloszewski

Managing the video captured from your IP cameras is an important function of your surveillance system.  I’ve talked about the hardware platform and software platform options that are available.  Once you’ve made the right hardware and software choices for your surveillance system what features and functions can you expect from the video management system?

This post is about recording and viewing features which probably sounds like the simplest and most obvious functions but, there are interesting options available that you may not have considered.

Are Analog Cameras Cheaper Than IP Cameras?

December 16, 2010 by Nathan Miloszewski

A couple days ago I linked to an Axis study that set out to prove that the cost of IP surveillance is now less expensive than its analog counterpart.

Now there is a healthy debate over at IP Video Market Info about the validity of this study.  Check it out:

Debating Axis’s IP vs Analog Cost Comparison

Some of the major sticking points are:

  • The Axis’s study assumes that no surveillance equipment is currently being used (i.e., ‘greenfield’).  A majority of organizations buying surveillance systems already have some cameras and cabling installed and a large portion of that infrastructure can and regularly is reused.
  • For any given feature set, IP cameras always cost significantly more than analog. While a DVR costs more than PC plus VMS software, that increase in cost is less than the savings on the camera side.
  • Is IP still worth it?  Cost isn’t everything, a price comparison can still favor analog, and Megapixel IP camera resolution (a big IP advantage) was not mentioned.

The flexibility, scalability, and high quality images set IP cameras apart from analog.  Remote access of live images from anywhere in the world including viewing video surveillance on your phone puts analog in the backseat, in my opinion.

Like any other kind of technology, over time, functionality continues to increase as the price goes down.  There may be debate now over some marginal price differences but that surely will not last.
