Q: What wireless security system to use for an RV or 5th wheel?
I am looking for protection that will notify local police not just make noise to hopefully scare potential robbers away. I want a system similar to the one in my house but for when we travel or are at a location for a period of time. Does anyone know of any companies that offer this service?

A: There are now entirely self-contained home security systems that are made for unique applications, (dorm rooms, boats, construction sites, etc). You may want to look into these as an option. They're not cheap (they're not overly expensive either), but they're worth the investment.

Q: how can you hookup a wireless security system?
I want to setup a security system with a camera and a video capture board or do I really need one?

A: well if you buy a system then it will have directions, as for do you really need one, only you can answer that. good luck.

Q: What is the best wireless security system that is connected to the Internet?
I am specifically looking for security systems for my home, not my computer. Thanks

A: If you google wireless router comparisons you will find lots and lots to wade through. For my own ideas: Unless you have need of a longer-range router, don't get one of the newer ones with longer range. (The longer the range, the greater the opportunity for others to find and use it.) You want to be able to do/use the following: -deliver hardware firewall (NAT), which will not respond to port-focused pings or inquiries from outside your network (operates in stealth mode) -turn off the broadcast of the ID (each one comes with a factory installed default, e.g., linksys for Linksys routers) -change that name, to name the now-not-broadcast ID to something meaningful to you -MAC filtered (allow access only to those machines for which you have entered the MAC ID) -WPA-level encryption Sniffers (think police scanners for wireless frequencies) can detect and intercept the radio traffic between computers and routers. In principle, they can be used to identify the network name and forge a MAC to allow access. That is why encryption is essential, and for security, WPA is the tops available (I think). WEP encryption can be broken in a matter of seconds-to-minutes. I have a Linksys, lower end router in my home that does all these things. Good luck.

Q: I'm looking for a wireless security system for my new jeep wrangler?
Does anyone no of such an item as a wirless security system for a vehicle. Im paranoid about tampering w/the wiring harness and having my factory warranty affected. I want a motion sensor so I can feel comfortable when a park and the top is off that no one will be crawling through the jeep trying to steal anything. Any suggestions would be greatly appreciated. Thanks

A: get a dog, a BIG dog, and make his kennel your jeep. guaranteed to keep most stranger out of your glove box or arm rest box!!!

Q: I would like to buy a wireless outdoor camera security system. Any suggestions?
I don't want to spend a fortune, but I'm not cheap either. Does anyone know of some decent wireless systems with about 4 cameras that I can mount outside and view from either my TV, Computer, or a monitor that comes with the system? Any help is appreciated.

A: First of all, if you are looking for a good usable image you probably want to stay away from the offshore gunk being schlepped off on the geeknet and big-box stores. There are a number of ways you can go, as for viewing camera's on TV there are channel inserters available which will superimpose your video onto a channel on your CATV. Another method is wireless UHF transmitters, however the neighbours will also be able to see snippits of your video (Which may or may not be a good thing, depending on your openness) Another method is to use a networkable DVR which you can access through your Local network (could also be accessable remotely if you have a static IP). If you don't already have one, you will have to get a multi-port router for this to work. Cheap only 30 to 150 bucks. You could also get a stand-alone surveillance system with a video switcher / sequencer or quad display. This will only record if you attach a recorder, but if you are looking to view only this could be the solution for you. If you take a look back in my answer history there was a similar question where I went into more detail on the differences between Switchers, Mux's, Quad's and DVR's. I also wrote an article on camera's awhile back, it is fairly old, however most of it still applies. There is more information which may help on my website at http://www.keepsafesystems.ca. I hope this helps you out in your endevour. ---------------------------------------------------------------------- The starting point of any C.C.T.V. system is the camera. Simply stated, a camera is a light sensitive device that converts particles of light into electrical impulses, however, there is a vast difference in the quality of cameras available to the consumer. Factors that differentiate the various cameras include whether they are color, black and white, light sensitivity, image resolution and image transfer technology. The consumer must also consider the inherent advantages and disadvantages in each of these different camera technologies and decide which features best fit their individual needs and goals. In the past, color cameras have been both very expensive and lack-luster in their image performance, when compared to black and white cameras. New technology is now bringing the innovative technologies closer together in both the price and performance scale. The current differences between the two technologies are almost entirely limited to light sensitivity and light reactivity. Light sensitivity is measured in LUX. The lower the LUX rating, the higher the sensitivity to light. It is important to keep in mind that even the best-rated cameras are limited by the technology of the day, as well as the visibility conditions present at the time of the surveillance. Although great advancements in low light surveillance continue to be ongoing, the image quality in a low light situation will rarely be up to the standards of daylight surveillance. Color cameras, although much more appealing on the outside when compared to their black and white counterparts, generally offer less low light sensitivity than a black and white camera. The other advantage of black and white cameras over color cameras is its ability to "see" infrared light, which is invisible to the human eye. You can test this by aiming a standard television remote at a black and white camera while watching the monitor, the flashes you see are bursts of infrared light. The advantage of this becomes apparent in the ability to light up a dark area with infrared light, thus making images visible in almost pure darkness. With the color camera the area will appear unlit, however, to a black and white camera, the area will appear almost like daylight. The black and white camera‚s reactivity to the invisible light spectrum can also pose a disadvantage in certain applications. Infrared light, although not visible to the human eye, is found in abundance in many everyday situations. For example, when aiming a black and white camera at hot pavement, it will "confuse" the camera resulting in an unbalanced image. Professional grade black and white cameras often incorporate infrared cut-filters. These cut-filters inhibit the infrared light spectrum in turn decreasing the cameras low light sensitivity. The C.C.T.V. Industry measures image resolution in horizontal lines. The higher the line rating, the clearer the image will appear. With this fact in mind, consider that all electronic components within a C.C.T.V. System, from the camera, to the VCR, to the monitor. These items are all rated in the same way. The actual resolution of the entire system will only be as high as the lowest rated item. For example, if you have a camera rated at 450 lines and a monitor rated at 300 lines, then the result will be 300 visible lines of resolution because the monitor is the lowest rated item in this example. Another point to keep in mind is that the line rating is "Total lines" not lines per inch. Therefore a 12" monitor with a 300 line rating has a far better clarity than a 17" monitor with the same line rating. The most recent and predominant advances in the C.C.T.V. Industry are the changes in image transfer technology. This technology deals with how the camera takes light particles and converts them into electronic images. Without going into too much detail, image transfer technologies include the following: Phosphorus Tube Cameras - This camera has low quality, old technology and is susceptible to "image burn". Image burn is when intense light sources will burn themselves into the camera‚s light receptor resulting in the image appearing "memorized". Although this is not a problem with modern day cameras, image burn can still occur on monitors. Tube cameras are also known for poor low light sensitivity. C.C.D - Also known as "Chip cameras". This camera is the most standard of cameras in the professional realm. C.C.D. cameras do not suffer from the problem of image burn and can incorporate various methods of signal processing, which offers a high level of flexibility to the installer. CMOS Transfer Cameras - These cameras are very small and continue to get smaller as the technology advances. Although very attractive in their size, CMOS cameras generally do not offer the signal processing, image quality or low light sensitivity of the higher priced C.C.D. camera models. However, the technologies are slowly growing closer together to the point where CMOS cameras may eventually take over the Surveillance Industry. The Surveillance Industry has continued to move towards the implementation of color cameras that switch to black and white, or even infrared in low light conditions. Although there are some models currently available on the market, the technology is not at a point where it is affordable enough to be manufactured on a large scale.

Q: What is the best home security system for a renter? Wireless? Do you have to have a phone line?
I need a cost effective burglar alarm system. I rent so I need something I can take with me when I leave. Do I need a monitoring service? Can you have a wireless system with no phone line? Is it better to buy a DIY system online and then purchase monitoring separately?

A: You should check out http://ucontrol.com. They have this cool box that you plug into any existing alarm system. It gives you redundant monitoring over broadband, cellular and a phone line - so if the robber cuts your phone line, you;re are still in good shape. It also lets you control and monitor your alarm system remotely from the web or your cell phone. Best part is you can take the box with you when you move and plug it into another system at your next location.

Q: Hooking up a wireless security camera system to a computer = HELP?
We have a security camera system that hooks up to our TV -- we want to hook it up to our computer system. It has male ends of RED & YELLOW for audio and video (male) -- what do we need to plug it into the computer? Thanks!

A: Here's the trick, you can hook it up to a computer MONITOR, but hooking up to a computer would require a number of things like a camera to USB cable, and software that would interpret that data signal. Otherwise, even if you get the USB cable, it's just random video data. You'd need a video capture card, which is doable, but the format your camera uses may not be recognized. Basically, it's really complicated and may not work even if the sun and stars are in alignment on this.

Q: How do I set up a system that allows my security system to call out wireless?
I want to set up my security system to call out wireless to the monitoring center, at the moment it is calling out on a landline which I want to disconnect, I know I need a voip router connected to my security system but how does the computor or modem receive the signal and how does it dial out?

A: Perhaps the easiest way to do this is to purchase and install a GSM communicator. You'll want to check first to be sure your system is equipped to handle it, but if it is, this would solve your problem. A GSM module is used to communicate between your system and your central monitoring station, or a cell phone or private number (if you don't have monitoring). Many people buy them, even if they do have landlines. That way, if the landline were cut, the system could still communicate with the monitoring station. Good luck. The link below is to one particular GSM module that will work with any system (assuming the system is able to be GSM equipped). The link below that is to an article explaining what GSM actually is.

Q: New DIY wireless security system for your home.?
How to install a wireless security system: Go to a second-hand store, buy a pair of men's used work boots ... a really big pair. Put them outside your front door on top of a copy of Guns and Ammo magazine. Put a dog dish beside it ... a really big dish. Leave a note on your front door that says something like this: "Bubba, Big Mike and I have gone to get more ammunition - back in 30 minutes. Don't disturb the pit bulls, they've just been wormed."

A: Hahahaha. I have to try that. I's probably going to put on the back door, also, to make sure the burglar knows. That's very good and clever. Pretty good if you made it up.

A: hahahaha......loved it babe!! that should work. maybe i will try it. im just glad that it wasn't an energizer joke!! lol my limit is almost up. if i dont get all urs answered then i will finish in the morning.

Q: Wireless Security System?
Are wireless security systems efficient as hardwire systems? How often do you have to change the batteries on sensors?

A: Wireless security systems are now just as efficient as hardwired systems. This is mainly because of rolling code technology, smash proof monitoring, etc. Nowadays, the lithium batteries used in wireless systems are designed to last for about 7-10 years. I included a link to an article weighing wireless against hardwired. Good luck.

Q: how can adding a router to a companies wireless system pose a security risk to the company?
I work in a dept. where my office does not get the companies wireless signal. I installed a router to boost the signal in my office. They have now accused me of "weakening their security" and want to rep-remand me in writing. I have done nothing wrong and only installed it to improve my productivity while @ work.

A: As an IT professional and a personal user - I can relate to where you are coming from. One one hand, it is annoying not to be able to get the freedom of a wireless signal. However, the reason that you are not allowed to randomly add devices (routers, switches, etc.) is due to the ease of an outside user, possibly malicious user intercepting the data. Without getting to technical (your actual question is a career in itself, and they make good money), an unencrypted signal (without a key) can be picked up by anyone and public, shared company folders can be accessed. From this information, a malicious user can easily can access to deeper, more confidential information, either through user manipulation (saying they are the new hire from the IT department and asking for your password) or through more complex cracking techniques. I highly doubt that you possess the expertise needed to secure your wireless network correctly or at least to the company's standards, that is why you will get written up and no offense, but are lucky not to be fired. Even if you put a key in place, it is still very easy to break it. There are many reasons why you will get in trouble for adding a wireless router unauthorized to your company's network, but the above was the most basic and common reason. Honestly, be thankful that your getting a written warning and not fired; in most companies something like that is a fire able offense, no questions asked.

Q: Does x10 wireless security system realy work?


A: yes and no. they work, but not over a long distance. I had one of the cameras and it wouldnt transmit 20 foot line of sight. I could see the camera from the reciever yet the picture sucked. Now I use the wireless switches and x10 lamp modules and they are awesome, never had a problem until the batteries go dead.

Q: I have a d link router having model no. DI-514 and i want to know how to make my wireless system security?
enabled, how to setup the security so that only my laptop can access this router and not others. Please explain me in detais and steps to follow , I would highly appreciate your any help. Thanks

A: enter the configuration page ... go to security and set a password for the router ... make a wpa key ... maybe enable mac filtering and only allow the mac adress of ur adapter ... disable ssid broadcast ..

Q: Installing a wireless security system...?
Im installing 7 wireless cameras, and im just wondering if they are going to slow my internet down. Or vice-versa, will the internet interfere with the cameras.

A: IF all your cameras are on 2.4 gig and your internet is on 2.4 gig (B, G, N wifi) then yes it can and may interfere with each other. If on the other hand you get cameras that are 5 gig or even 900mhz and your wifi is 2.4 then they won't! Its always best to use different ranges for these devices. Check which "band" (frequency range) is in use on your cameras and on your wifi router. Get them in different ranges, avoid the issue!
