Today’s Webinar

SIS10-16 Webinar – Planning for Outdoor Video Security Projects Q&A
Poll Question #1
What are the two most important factors in determining an outdoor camera position?
1-mounting position & field of view
2-power & transmission path
3-vandal protection & weatherproof rated equipment
Answer: #2 – All are important, but power and transmission path are most important. They must be available before any
other choice is made.
Poll Question #2
Why is Line of Sight important in a wireless transmission?
1-It’s not important as long as the transmitter is within range of the receiver.
2-Transmission data travels in a straight line between the transmitter and receiver.
3-The wireless transmission will have a significantly reduced signal strength at the receiver when obstructions are close
to the signal path.
Answer: #3 – Transmission along the line of sight is subject to obstruction by nearby obstacles. Even those not directly in
the straight line path between transmitter and receiver. This area is called the Fresnel Zone. Some might have guessed
#2, but the transmission path is actually in an ellipsoid wave, not a straight line.
Poll Question #3
Why does distance between the camera and target area matter?
1-This distance is used to determine the Field of View for the camera.
2-This distance is important in determining the focal length for the camera lens.
3-This distance is important for determining the Pixels Per Foot and the resulting clarity of the image produced.
4-All the above.
Answer: #4 – All the above is correct. The distance between the camera and target area matter because of #1, #2, & #3.
The distance affects the field of view, focal length for the camera lens, and the resulting clarity or pixels per foot of the
image.

How do I know what type of PoE I need?
There is a couple of key things to know about your equipment. You may need standard PoE or PoE+ power.
Standard PoE (also designated IEE 802.3af) provides up to 15.4 Watts of DC power to each device (minimum 44 V DC and
350 mA). Only 12.95 Watts of power is assured at the device as there is some loss of power in the cable. Enough power
for most IP phones and wireless access points from all manufacturers.
PoE+ or PoE plus (also designated IEEE 802.3at) provides up to 25.5 Watts of DC power. This can be used to power
devices needing more power. When edge devices pushed the limits that PoE standards provided, PoE+ was created to
meet the needs.
Sometimes you have a proprietary power supply for a camera or IP device that provides nonstandard power for the
device. In these situations, use the recommended device.
Sometimes you have a device that simply won’t power with PoE, even though it is an IP network device. An example of
this is a PTZ camera that needs its own power supply or local power. These items usually exceed the amount of power
allotted for devices from the standard PoE or PoE+ switch.
Don’t assume bigger is better. If all you need is standard PoE to properly power your devices, don’t use a PoE+ switch.
You want to choose the most cost-effective choice needed.

Should I plan to use edge recording?
Edge recording is becoming more popular as a backup to central server recording. Axis Cameras are good at this and
provide good support for this need. This is a growing feature among a lot of IP camera manufacturers. VMS developers

are also getting into the game. Advanced VMS’s provide a capability to pull recorded video from edge storage on
cameras. LENSEC’s Perspective VMS will have this feature in the newest version of the software (due out in a few days).
I don’t recommend using edge recording as your only means of storage for outdoor camera locations. Unless you have
access to pull the video directly into the VMS or from the camera webpage, the only way you’ll be able to access the
video on the SD card is to go physically to the camera location and pull the SD card. This may not be easy if the camera is
hanging on a pole 25 feet in the air.
Edge storage is primarily a backup to your central storage. But, it is important to configure the edge storage and use it to
cover your bases.
What is the better frequency range I should consider for my wireless transmission?
Most transmitters rated for public use will be in the 2.4GHz or 5.8GHz range. You may also find transmitters that use
other frequency ranges such as 900MHz, 1.2GHz, and more. Some frequencies are restricted for commercial use. You
can find out more about this from Federal Communications Commission in the United States.
As a general rule of thumb, it is better to use 5.8GHz for transmission than 2.4GHz due to crowded frequencies. This
means there is greater potential for many 2.4GHz transmitting devices to be used in a vicinity creating RF interference
than devices operating in the 5.8GHz range.
What’s the best way to determine distances for cable runs or for camera to target distances?
When I perform site walks in the field, I always prefer measuring distances with a contractor’s measuring wheel. This is a
device you can pick up at a hardware store. It has a wheel on one end with a counter that measures off linear feet. This
is the most accurate way to calculate distances. Google Earth can only provide you with rough though relatively accurate
measurements.
Cable distance may be a little harder to measure, especially if it is running through conduit that is already buried in
concrete. If you can find an architects drawing with the conduit path identified, you can use an architect’s measuring
wheel to get an estimate of the cable run. Otherwise an educated guess may be in order based on live measurements
you can take onsite with a contractor’s measuring wheel.
Just be conservative in your estimate. And by that, I mean assume your cable run is longer than you measure it out to
be. This allows you a little room for error in your estimation.
What are the capabilities of wireless radios in terms of bandwidth?
Traditionally current radios can transmit 80mbs to 100mbs which is enough power to handle 4-5 2MP cameras on one
radio. Also, this technology is quickly developing and soon you will see what is called wireless fiber that will transmit a
GB.
