Here is the transcript: Wireless Customer: Hello, i need a wireless effective system to transmit video from analog cameras in outdoors at 700 ft Customer Support: Hi Wireless Customer, do you have a direct line of sight between the two areas. Wireless Customer: yes Customer Support: no trees in the way either (nothing at all in the way). Wireless Customer: and rain at half of year. no trees, full line of sight Customer Support: OK. You can use this system: <a href="http://www.cctvcamerapros.com/Wireless-Security-Camera-System-p/wifi-en95610.htm" rel="nofollow">http://www.cctvcamerapros.com/Wireless-Security-Camera-System-p/wifi-en95610.htm</a> Wireless Customer: ok, let me see, one minute Customer Support: with a video encoder on the camera end: <a href="http://www.cctvcamerapros.com/Video-Encoder-p/vivotek-vs7100.htm" rel="nofollow">http://www.cctvcamerapros.com/Video-Encoder-p/vivotek-vs7100.htm</a> and a decoder on the DVR end: <a href="http://www.cctvcamerapros.com/Video-Decoder-p/vivotek-rx7101.htm" rel="nofollow">http://www.cctvcamerapros.com/Video-Decoder-p/vivotek-rx7101.htm</a> Wireless Customer: ok, it work like IP wireless system? Customer Support: This explains basically how it works: <a href="http://www.cctvcamerapros.com/Wireless-Security-Camera-System-p/wifi-en95610.htm#wireless-camera-system-installation" rel="nofollow">http://www.cctvcamerapros.com/Wireless-Security-Camera-System-p/wifi-en95610.htm#wireless-camera-system-installation</a> The encoder makes the signal digital / IP based for the wireless bridge, then converts back to analog on the receiving end. Wireless Customer: so, what you think about rain, it affects video quality at this distance? Customer Support: If the rain is very hard, it can affect the signal. There is always some risk of interruption of connectivity with wireless equipment. Wireless Customer: ok, good Customer Support: if you want something very stable this is another option: <a href="http://www.cctvcamerapros.com/Wireless-Video-Surveillance-Transmitter-p/wifi-900xtrp.htm" rel="nofollow">http://www.cctvcamerapros.com/Wireless-Video-Surveillance-Transmitter-p/wifi-900xtrp.htm</a> It is much more expensive because it is a 900mhz system which can go through trees and some objects. We recommend this system when there are trees in the way and when the job is very high end. Wireless Customer: good, i going to check information and contact sale department... Customer Support: OK. Please let us know if you need any additional help. Wireless Customer: thx Mike on "Wireless Security Camera System Questions" http://videos.cctvcamerapros.com/support/topic/wireless-security-camera-system-questions#post-195 Mon, 21 Dec 2009 17:03:25 +0000 Mike 195@http://videos.cctvcamerapros.com/support/ Reply from customer: In the photo the total area that the individual targets are placed on is 36 inches x 36 inches. The individual targets that I staple to the surface vary in size and shape ( 8 inches to 12 inches in diameter) and are typically as shown in the photo. The placement of the camera will be in front of and below the target. The minimum distance from the target has to be 8 feet to 10 feet but this distance can be increased as required. The range is outdoors but the camera and equipment will be setup for the shooting session and put away when finished. Nothing will be left outside. This will be a portable system. The re-sized photo looks great. Response from CCTV Camera Pros: I setup a test environment where I placed a 5 megapixel camera 10 feet away from an area about 3.5 feet wide. Please look at the attached pictures. I used the 5 megapixel camera and took still shots at 2 megapixels and 5 megapixel resolution. I took one shot with a simulated target with bullet holes using a standard 8.5 x 11 printer paper. I also took another shot without the target so you can see the clarity with text on the product box I used. Click on the below link to see the 2 megapixel and 5 megapixel camera images: <a href="http://videos.cctvcamerapros.com/images/megapixel-cameras/5-megapixel-security-camera-image.jpg" rel="nofollow">http://videos.cctvcamerapros.com/images/megapixel-cameras/5-megapixel-security-camera-image.jpg</a> <a href="http://videos.cctvcamerapros.com/images/megapixel-cameras/5-megapixel-security-camera-image-text.jpg" rel="nofollow">http://videos.cctvcamerapros.com/images/megapixel-cameras/5-megapixel-security-camera-image-text.jpg</a> <a href="http://videos.cctvcamerapros.com/images/megapixel-cameras/2-megapixel-security-camera-image.jpg" rel="nofollow">http://videos.cctvcamerapros.com/images/megapixel-cameras/2-megapixel-security-camera-image.jpg</a> <a href="http://videos.cctvcamerapros.com/images/megapixel-cameras/2-megapixel-security-camera-image-target.jpg" rel="nofollow">http://videos.cctvcamerapros.com/images/megapixel-cameras/2-megapixel-security-camera-image-target.jpg</a> I did not have a IP-V97161 out of the box to test with so I used the following 5 megapixel camera with a 4.5 to 13mm varifocal lens: <a href="http://www.cctvcamerapros.com/5-Mega-pixel-Security-Camera-p/ip-av95105dn.htm" rel="nofollow">http://www.cctvcamerapros.com/5-Mega-pixel-Security-Camera-p/ip-av95105dn.htm</a> This is our top of the line megapixel camera so the image looks pretty amazing. I did compress the images before I emailed them so the quality is degraded slightly. Please let me know what you think and if you have any other questions. Mike on "Wireless Security Camera System Questions" http://videos.cctvcamerapros.com/support/topic/wireless-security-camera-system-questions#post-192 Mon, 21 Dec 2009 12:32:39 +0000 Mike 192@http://videos.cctvcamerapros.com/support/ Follow up questions from gun range owner: Mike, I have one additional question. The target area is 36 in. x 36 in. There are multiple targets in that area as shown in the attached photo (taken with a HP Photosmart M22). Will I be able to zoom in and see each of the targets close enough to observe the bullet holes? If the <a href="http://www.cctvcamerapros.com/2-Megapixel-IP-Camera-p/ip-v97161.htm">IP-V97161 megapixel camera</a> will give me an image like the attached photo it should work just fine. Below is my latest updated diagram that shows how the wireless camera system and solar power will layout. <img src="http://videos.cctvcamerapros.com/images/wireless/wireless-security-camera-system-solar-powered.jpg"> I have researched batteries, inverters and solar chargers. I know this is not your area of expertise but I thought you might be interested. I plan to build two boxes like small suitcases containing the battery inverter and solar charger. One will supply the notebook and one antenna, the other will supply the camera and other antenna. I still have to calculate the power requirements before I make any selections. Inverters <a href="http://www.invertersrus.com/" rel="nofollow">http://www.invertersrus.com/</a> <a href="http://www.theinverterstore.com/?gclid=CNiF9aeO5J4CFRHyDAodl18RMg" rel="nofollow">http://www.theinverterstore.com/?gclid=CNiF9aeO5J4CFRHyDAodl18RMg</a> Solar Panels <a href="http://www.batterystuff.com/solar-chargers/" rel="nofollow">http://www.batterystuff.com/solar-chargers/</a> <a href="http://www.siliconsolar.com/visual-directory/solar-battery-chargers.html" rel="nofollow">http://www.siliconsolar.com/visual-directory/solar-battery-chargers.html</a> Batteries <a href="http://www.batteryspace.com/" rel="nofollow">http://www.batteryspace.com/</a> <a href="http://www.batterymart.com/" rel="nofollow">http://www.batterymart.com/</a> Reply from CCTV Camera Pros: Thank You for the links to those solar power, battery, and power inverter resources. We are going to document them on our support forum to share with other people looking to do similar solar and battery powered security camera projects. Below is a link to the image that you took resized to exactly 1600 x 1200 pixels which is 2 megapixel. Two Megapixel IP Camera Image <a href="http://videos.cctvcamerapros.com/images/wireless/2-megapixel-IP-Camera-image.jpg" rel="nofollow">http://videos.cctvcamerapros.com/images/wireless/2-megapixel-IP-Camera-image.jpg</a> That is the size of the video and images that the camera is capable of capturing. However, one thing to consider is the total size of those targets. Can you please give me the exact size, width and height of the total area? We can then calculate what lens will work best for your application and at what distance you need to mount the camera. I have a feeling that you may need to mount the camera farther back from the gun targets than you first wanted. Also, is the gun range indoors or outdoors? If it is outdoors and the camera will be left outdoors, then you will also need to purchase an outdoor housing for the camera like any of these: <a href="http://www.cctvcamerapros.com/CCTV-Camera-Housing-p/hpro-605.htm" rel="nofollow">http://www.cctvcamerapros.com/CCTV-Camera-Housing-p/hpro-605.htm</a> <a href="http://www.cctvcamerapros.com/CCTV-Camera-Housing-p/hbpro-601hb.htm" rel="nofollow">http://www.cctvcamerapros.com/CCTV-Camera-Housing-p/hbpro-601hb.htm</a> <a href="http://www.cctvcamerapros.com/Arecont-Vision-Camera-Housing-p/hsg1-o-w.htm" rel="nofollow">http://www.cctvcamerapros.com/Arecont-Vision-Camera-Housing-p/hsg1-o-w.htm</a> Please let me know the dimensions of the entire target area. Mike on "Wireless Security Camera System Questions" http://videos.cctvcamerapros.com/support/topic/wireless-security-camera-system-questions#post-190 Sun, 20 Dec 2009 12:55:48 +0000 Mike 190@http://videos.cctvcamerapros.com/support/ Follow up questions & comments form the gun range owner: The sketch is kind of crude because I used MS Paint and I’m no artist but it gets the job done J and I have made some corrections to the sketch. The shooting range is in a remote location. It is accessible using a dirt road. There is no 110 VAC power available. It’s out in the woods. J Since I don’t have a 110 VAC power source available at our location, I will use a battery and an inverter to provide the 110 VAC. I can then use the POE and plug my notebook computer in using the standard power supply. My laptop has wireless network capability built in but for this application I won’t need to connect to anything else. I could connect with the wireless connection if you think it would be better. The camera has ePTZ. I am not familiar with that. I assume it simulates the camera connected to a mount that moves. Is the ePTZ function controllable through the network connection and how much movement is there? The target is 36 in x 36 in. and I need to scan and focus in on a specific area of that surface. Reply from CCTV Camera Pros: I would definitely recommend connecting to the laptop wired, and not wireless to the bridge antenna. In regards to the ePTZ function of the IP camera, it stands for electronic pan tilt zoom. The camera does not actually move, but instead allows you to digitally zoom in to different part of the video focus area. This camera is able to support that because it is a megapixel camera and supports high resolution. So, for example if you have the camera focused on the width and height of the target and you need to zoom in a bit more on a specific part of the target to confirm it was in fact hit, you will be able to do that using the ePTZ function. Please let me know if you have any other questions. It is great that you are doing all of this thorough research upfront to make sure you get exactly what you are need. It is no problem if you have more questions. We prefer to answer as much as possible upfront rather than have you get something that does not fit your requirements.

I know this is a unique application and I want to get it right before making a purchase. The way I see it is as follows: The camera connects to one of the antennas via a cat-5 cable. Power input for the camera is 12 vdc and 24 vdc for the antenna. On the other end the notebook computer connects to the other antenna via another cat-5 cable. Power requirements are 12 vdc for the notebook and 24 vdc for the antenna. I will take care of the power requirements. Do these connections sound correct to you? Refer to sketch below. Are the connections correct? Don’t worry about the power supplies. I’ll take care of the power requirements. <img src="http://videos.cctvcamerapros.com/images/wireless/wireless-camera-system.jpg"> CCTV Camera Pros reply: Nice job on the diagram. Yes, you are correct. Let me just add a few details. The the wireless transmitters include a POE power supply. It it is basically a very small box (about 2 inches long) that has three connections. 1) A power input which gets connected to the AC power supply included with the unit (the power supply is basically about the same size as a cell phone battery charger and connects to a standard 110 power source). 2) An RJ-45 / Cat5 POE out which connects to the antenna to provide its power and connectivity 3) An RJ-45 / Cat5 Ethernet input to connect to the camera. So again, your diagram is correct, but I just want to make sure you understand the details of how the power and connectivity is being delivered to the wireless antennas. Also, on the bridge side, typically there is a network switch that both the laptop and the access point antenna connect to, instead of connecting the antenna directly to the laptop, but for your application, I think the direct connection will be fine. If you ever want other device to see the camera on a network, you can add a network switch at any time. Last, I want to mention that CCTV Camera Pros offers a service where we can pre-configure the wireless bridge and camera for you so that when you get the equipment everything will connect for you when you power it up. As part of this service, we also make sure that all IP devices have been updated to the latest firmware version. The cost for this is $20 per device, so $60 total for this application in case you are interested in that. Please let me know if you have any further questions and have a great weekend.

I was planning to power the antennas, camera, network switch and notebook computer with rechargeable batteries and solar chargers. What do you think? CCTV Camera Pros reply: It is certainly possible to power both the camera and wireless camera system with solar or battery power, but I am sorry that I can not offer any expertise in that area. We have some installers that we are partnered with that have deployed applications like this, but we do not get involved in that piece at this time. Please let me know if I can help with anything else Mike on "Wireless Security Camera System Questions" http://videos.cctvcamerapros.com/support/topic/wireless-security-camera-system-questions#post-187 Fri, 18 Dec 2009 18:30:17 +0000 Mike 187@http://videos.cctvcamerapros.com/support/ An owner of a gun range recently contacted CCTV Camera Pros with the following questions: I want to build a wireless system to monitor a target on a shooting range. The system will be used in daylight and fair weather. The system will consist of a camera, transmitter, receiver and monitor. I will need a high resolution box camera with possibly a varifocal lens that has enough resolution to be able to clearly observe bullet holes in the target. The camera will be placed 8 to 10 ft. in front of and slightly below the target and shielded from the bullets. The target will be between 300 ft. and 900 ft. from the shooter and the monitor. I plan on using either a notebook computer or a standard LCD monitor connected to the receiver. What is your recommendation for the camera, transmitter and receiver? What operating frequency do you recommend? The range is in a fairly remote area and interference should not be a problem. There are no obstructions between the transmitter and receiver. CCTV Camera Pros supplied the following recommendation: Thank You for contacting CCTV Camera Pros. Here is the equipment that I recommend: <a href="http://www.cctvcamerapros.com/Wireless-Security-Camera-System-p/wifi-en95610.htm" rel="nofollow">http://www.cctvcamerapros.com/Wireless-Security-Camera-System-p/wifi-en95610.htm</a> <a href="http://www.cctvcamerapros.com/2-Megapixel-IP-Camera-p/ip-v97161.htm" rel="nofollow">http://www.cctvcamerapros.com/2-Megapixel-IP-Camera-p/ip-v97161.htm</a> You also need a network switch to connect the wifi receiver and your laptop to the same network if you do not already have one. This system is dual band so it can use 2.4Ghz or 5.8Ghz frequencies. Also, you probably noticed that I recommended a megapixel IP camera (box style). That is because the wireless system is IP based and the camera will work with IP cameras plug and play. If you want to use an analog box camera, it will be much lower resolution and you will need a video encoder near the camera which will make the price close to the same as the megapixel camera, but the solution will have less resolution / image quality. Please let us know if you have any questions. Sincerely. -Mike Mike on "Wireless Camera System Questions II" http://videos.cctvcamerapros.com/support/topic/wireless-camera-system-questions-ii#post-164 Mon, 16 Nov 2009 16:51:15 +0000 Mike 164@http://videos.cctvcamerapros.com/support/ A customer contacted CCTV Camera Pros with the following questions: I have a client in Ocean City Maryland that wants to place 4 outdoor wireless camera set up. He will mount them on poles that have power however he won’t be able to easily run cable to it so he wants to go wireless. They have a wireless environment for the entire site and want to use that if possible. He then wants to have the images up on his web site for open access. He wants to view the front of his hotel with 2 cameras and have 2 camera on the dock. Let me know what your thoughts are and any additional information I need to gather. Can we use their existing wireless or do we need to set up a dedicated wireless system? CCTV Camera Pros response: My recommendation is to use 4 of these outdoor IP cameras: <a href="http://www.cctvcamerapros.com/Outdoor-IP-Camera-p/zavio-f731e.htm" rel="nofollow">http://www.cctvcamerapros.com/Outdoor-IP-Camera-p/zavio-f731e.htm</a> These cameras have a built in web server and can be accessed over the Internet from Internet Explorer. and one of these wireless camera systems: <a href="http://www.cctvcamerapros.com/Wireless-Security-Camera-System-p/wifi-en95610.htm" rel="nofollow">http://www.cctvcamerapros.com/Wireless-Security-Camera-System-p/wifi-en95610.htm</a> That wireless camera system comes with 2 transmitters. Instead of configuring one as an access point and one as a bridge, both can be configured as bridges to connect to their existing wireless access point as long as it is using a wireless B or G that is compatible with these transmitters. You would connect each of the two camera pairs to one of the access point antennas using a network switch like this one: <a href="http://www.cctvcamerapros.com/5-Port-Network-Switch-p/net-sw5p.htm" rel="nofollow">http://www.cctvcamerapros.com/5-Port-Network-Switch-p/net-sw5p.htm</a> You will also need a POE injector for each IP camera: <a href="http://www.cctvcamerapros.com/POE-Injector-Kit-p/poe-12v48.htm" rel="nofollow">http://www.cctvcamerapros.com/POE-Injector-Kit-p/poe-12v48.htm</a> All of these components can be housed inside a weatherproof outdoor enclosure and mounted to the pole also: <a href="http://www.cctvcamerapros.com/NEMA-Weatherproof-Outdoor-Enclosure-p/nema-p14104.htm" rel="nofollow">http://www.cctvcamerapros.com/NEMA-Weatherproof-Outdoor-Enclosure-p/nema-p14104.htm</a> <a href="http://www.cctvcamerapros.com/Pole-Mount-Security-Camera-Bracket-p/cm-p101.htm" rel="nofollow">http://www.cctvcamerapros.com/Pole-Mount-Security-Camera-Bracket-p/cm-p101.htm</a> Please let me know if you have any questions or need anything else for this one. Sincerely. -Mike Mike on "Wireless IP Camera System Questions" http://videos.cctvcamerapros.com/support/topic/wireless-ip-camera-system-questions#post-73 Tue, 18 Aug 2009 22:34:32 +0000 Mike 73@http://videos.cctvcamerapros.com/support/ Danny, Please see answers below: 1) How do you connect these cameras to the wireless network? You can use add on wireless receivers like these: <a href="http://www.cctvcamerapros.com/Wireless-Security-Camera-System-p/wifi-en95610.htm" rel="nofollow">http://www.cctvcamerapros.com/Wireless-Security-Camera-System-p/wifi-en95610.htm</a> These are actually sets consisting of both transmitters & receivers. With each of these you can configure both of the antennas to be receivers to connect to an existing wireless network. 2) Does each camera have its own IP address that we could set up a link for online? Yes. 3) How would we go about doing so? You can access the cameras directly from Internet Explorer web browser. 4) Can multiple users view the same camera feed simultaneously? Yes, but keep in mind that you are limited by how much bandwidth your network can support. The more users that log on, the slower the response time will be. 5) How difficult are the cameras to install? Are there any special steps that we would need to be aware of? As long as you can run the cables between the cameras and wireless add-on, and you can supply power to the cameras, the rest is easy. 6) What do you think about the feasibility of our project? It is feasable. You just need to make sure it is realistic for you as far as how much bandwidth you have available on your network. 7) Do you have a ballpark price estimate for everything we would need? The link above will show you the pricing for the wireless antennas. That price would be per 2 cameras if you have an existing wireless mess network already in place on your campus. Here are some links to IP cameras that we recommend with pricing: <a href="http://www.cctvcamerapros.com/IP-Network-Camera-p/zavio-f210a.htm" rel="nofollow">http://www.cctvcamerapros.com/IP-Network-Camera-p/zavio-f210a.htm</a> <a href="http://www.cctvcamerapros.com/Dome-IP-Camera-p/zavio-d510e.htm" rel="nofollow">http://www.cctvcamerapros.com/Dome-IP-Camera-p/zavio-d510e.htm</a> <a href="http://www.cctvcamerapros.com/Outdoor-IP-Camera-p/zavio-f731e.htm" rel="nofollow">http://www.cctvcamerapros.com/Outdoor-IP-Camera-p/zavio-f731e.htm</a> 8) Is this even the best way to go about implementing such a system, or are there other setups that you feel would be better? A wired system is always more reliable than wireless. If you can tap in to the network using wiring, you are better off. Please reply if you have further questions. Sincerely. -Mike Mike on "Wireless IP Camera System Questions" http://videos.cctvcamerapros.com/support/topic/wireless-ip-camera-system-questions#post-71 Tue, 18 Aug 2009 16:24:45 +0000 Mike 71@http://videos.cctvcamerapros.com/support/ We were recently contacted by a customer with the following questions: My name is Danny and I am part of the student government at Indiana University. We are working on implementing a system that would allow any student to go onto the internet and be able to get a live feed of the work-out facilities that we have. We feel this would be extremely useful for our students because often the basketball courts and weight-training areas fill up around peak hours, creating a backlog of people waiting to use machines or to get on courts. By having a camera system, students would be able to check how busy the facilities are before they decide to go, saving students time and freeing up the facilities. I’ve been doing some research on potential solutions. Based on what I’ve seen, it seems to me that purchasing multiple wireless IP network cameras would fit our needs. We have a secure wireless network that covers the campus, so it would be much easier to utilize the Wi-Fi than to run Ethernet cables along the walls. However, there are a few things that I don’t understand: <ol type="1"><li>How do you connect these cameras to the wireless network?</li><li>Does each camera have its own IP address that we could set up a link for online? How would we go about doing so?</li><li>Can multiple users view the same camera feed simultaneously?</li><li>How difficult are the cameras to install?
