VideoIQ also delivers the only solution designed for self-monitoring, professional outsourced monitoring or on-site guard monitoring. With superior real-time threat detection, customers can effectively prevent theft and vandalism at 1/5th the cost of an onsite guard, or make their own guard force more effective and efficient.
Outsourced: VideoIQ’s video surveillance solutions are purpose built to support remote, third party professional monitoring. Replacing the function of onsite guards, at a fraction of the cost, outsourced monitoring organizations receive alarms in real-time and are specifically trained to access the threat and respond 24/7.
On-Site: VideoIQ’s advanced adaptive analytics continuously monitor their field of view 24/7. By receiving real-time alerts when specific behaviors are detected, VideoIQ’s surveillance solutions augment onsite guard teams, making them more effective and efficient, delivering better coverage and rapid response at lower cost.
VideoIQ iCVR-HD cameras are VideoIQ’s highest resolution cameras, delivering dramatic 1080p video at up to 30 frames per second. With almost seven times the resolution of a standard VGA camera, the iCVR-HD allows customers to digitally zoom in for superior detail, or cover nearly three times the horizontal area — reducing costs by requiring fewer cameras for the same area.
• IQTrack™. VideoIQ iCVR-HD cameras use unique VideoIQ intelligence to automatically identify, track and digitally zoom in on suspicious objects, delivering enhanced detail, while continuing to monitor and record the entire scene.
• Email notification. Whenever a rule configured by the customer is triggered, emails can be sent directly to any device supporting video email attachments or video mms, including cell phones, and smart phones, making it ideal for roaming guards or remote facility managers.

PoE In Security
Power over Ethernet or PoE technology describes a system to pass electrical power and data over Category cable. PoE has entered into the lexicon of electronic security, initially in applications involving PoE enabled IP cameras, PoE enabled UPT technologies, and PoE enabled IP based EAC (Electronic Access Control) modules.
The IEEE standard for PoE requires Category 5 cable or higher for high power levels, but can operate with Category 3 cable for low power levels.
Power is passed over two or more pairs of wires in the Ethernet cable.
Power comes from either a PoE-enabled network switch, a midspan device such as a special purpose hub, or a standalone injector.
The original IEEE 802.3af-2003 PoE standard provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA) to each device with just 12.95 W available at the powered device due to loss in the cable. The updated IEEE 802.3 at 2009 PoE standard (also known as PoE+ provides up to 25.5 W of power.
The 802.3 at standard provides 51 W of power over a single cable by utilizing all four pairs in the Cat.5 cable.
Power sourcing equipment:
The PSE is a device such as a switch that provides the power source. When the PSE is a switch, it’s called an endspan.
If it’s an intermediary device located on the network cable somewhere between a non PoE switch and a PoE device, it’s referred to as a midspan.
One type of midspan is an injector which is an interface placed in series between the network switch and the PD (explained next). A power supply connects to the injector, and sends the power in the direction of the PD. Another type of midspan is a hub which manages both the data as well as injects the power onto the network cable.
A powered device (PD) is the object of the injection such as a electronic access control module, IP Camera, PoE phone or an access point.
Many powered pevices have an integral auxiliary power connector for an optional, external, power supply.
Having multiple ways to power a PoE PD can enable the system designer to provide for continued powered operation even if there is a power failure.
Two PoE Modes, A and B, are available. Mode A delivers phantom power on the data pairs of 100BASE-TX or 10BASE-T. Mode B delivers power on the spare pairs. PoE can also be used on 1000BASE-T Ethernet in which case, there are no spare pairs and all power is delivered using the phantom technique.
