Distributing baby-monitor video?  

post #1 of 19
Thread Starter 
I am purchasing a house that is currently under construction, and I am still ahead of the cutoff for wiring changes. Having said that, the house is prewired with RG6 coax and CAT 5 in every room, and really the easiest modifications are to simply add additional RG6 or CAT5 runs as required (i.e. no other type of cable).

I would like to set up a "baby monitor"-type video system that allows video and sound monitoring in two different rooms at the same time. I've seen all kinds of systems available on the internet, but I have not yet found a system (or pieces that would let me make a system) that meets all of my needs.

These are my requirements:

1) Cameras must be able to see in total darkness (i.e. say 15 feet). Color would be preferred, but BW is ok. Ideally the cameras would be white.

2) Cameras should have a mic and transmit audio.

3) Cameras should use either RG6 coax or CAT5 for video/audio signal transmission.

4) Would like to be able to view camera output on any standard TV in the house. Ideally one channel could be "tuned" on a receiver TV, and the image/sound would periodically cycle between each camera (e.g. show each camera image for 15 seconds before switching to the other). What would be even better is if, say, each camera had a dedicated channel, with a third channel alternating between the two... I'd prefer to use RF and simply tune a "channel" on the TV to get the image, but if I had to use actual RCA A/V inputs, that would be doable.

Does anyone know how I can assemble such a system? I have scoured the internet looking at tons of camera and monitoring equipment, and I have not been able to come up with a system that meets all of my requirements.

Thanks for your help.

I don't have a ton of experience in this area, but I will take a stab at some of your questions.

Colour cameras do not usually have low lux capability. In order to see in total darkness you will need a camera with IR (eg. Channel Vision CV5124).

There are few cameras on the market with audio. This, I have been told is due to legality issues of privacy. X10 has a line of cameras (B&W and colour) with audio embedded, but the resolution and lux is BAD!

The last part is easy. Use RG-6 (with RCA jacks) to send your video (& audio if you find a camera) to a modulator. The Channel Plus 5425 should fit your bill. Install the modulator near your media center as you need to route your cable/antenna signal through it. You can now program which channel each camera will be on.

Hope this helps!

Thanks - I have seen most of this hardware (on the internet) already. Regarding the cameras with IR, I learned the hard way that they are not all the same. I purchased a Phillips set a while ago, and then saw that the range of the IR emitters in total darkness was only about 18", which made it basically useless. I was hoping for specific recommendation for a camera that has up to ~15 foot range in total darkness.

Audio is a must, and I have seen several cameras with audio, but they tend to use a 6-pin din cable that also delivers power, etc, which makes it more difficult to figure how to distribute the signal. I guess that I could add a mic myself to a camera without audio, but I haven't seen "add audio" options for cameras that are video only...

"The last part" isn't as easy as you pointed out. The Channel Plus 5425 would be ideal, but AFAIK this does not solve my requirement "4" above, i.e. that I can tune one channel on my TV and have the image/audio automatically alternate periodically between the two cameras.

Thanks for the help.

Smarthome has most of the items you would need to do this. Here is a nice box that will take 4 cameras in and give you a single output that is either composite, S-video or VGa.
https://www.smarthome.com/7757.html
It also has the ability to put all 4 images on the screen simultaneously. You could easily route this signal as a composite signal and input it on one of the AV inputs on most TVs that would save using a modulator. Otherwise get a modulator and input either S or composite to the modulator and route as RF in the form of a single channel on a single 75 ohm coax. If you want color cameras with low lux and audio your best bet is to watch for them to go on sale at your local electronics store. You don't need digital or small flat panel fold out screens so look for the basics with low light capability. As far as see in the dark, that will kick the price up again and require that you purchase some IR illuminators like Sony has. Not sure what the life on them is. I would recommend defining the basic system and wiring for that.

The 7757 is almost right, but doesn't handle audio. It also won't cycle between cameras - for two cameras it can only do a PIP. But the lack of audio is the main issue for me on this unit.

It sounds like you are talking about actual camcorders, which would be a lot more expensive, if I understand correctly...

Thanks.

I am trying to do the same thing. I can't decide between this kinda cheapo package http://shop.store.yahoo.com/salestor...sg12realt.html which I think I can put the monitor in the most used place, and then take the composite video and modulate it and put the quad picture into the CATV system on its own channel.

I think the alternative, is to buy 4 cameras (which would cost about the same $$ as the Lorex), plus buy a quad, but that won't get 2-way sound.

If the Lorex had a remote (I can't tell--doesn't look like it) then with IR repeaters you could view and control it from multiple locations, but you probably could only listen and not get 2-way audio.

The problem with all this crap is its big bucks on to spend on a flyer. Its hard to tell which stuff you need and will it work with other stuff. After I learn more, I will call some of the tech/sales lines, but it is hard to hold off buying until I get educated.

This is a great forum-I never even thought this stuff was accessible.

I would recommend using a black and white camera with an ir illuminator if you want the ability to 'see' in total darkness. The IR is invisible to the naked eye, so it won't throw any additional visible light into the room and you'll easily exceed your 15' range. Have the low-voltage sub run a siamese RG-59 (solid copper center with a copper braided shield), and 1 Cat5 to each camera location. You would mount a 3-channel modulator and a multiplexer in the distribution hub. Then take each of the camera's video feeds and split them in the hub to the multiplexer, and the modulator. Take the multiplexed output and feed that output into the 3rd channel of the modulator. This will allow each TV in the house to receive one channel with both pictures on a split screen, another channel with one room, and third channel with the other room. We've done this with many cameras feeding out to many tvs and it works quite well. For the audio you would use the second RG-59 or cat5 depending on your camera type.
post #8 of 19
I forgot to mention, since you'll be running 2 cameras each with a mono audio signal, you can also split those audio feeds at the hub and run 1 camera's audio feed into the left, and 1 camera's audio feed into the right channel of the modulator input that has the multiplexed feed. That will give you sound from both rooms on the same channel that has the split screen. I would suggest using the Channelplus products like the 5545 (stereo audio inputs and outputs) We're also in the San Diego area and are pretty familiar with every builder's prewire systems. If you want to e-mail me, I can probably give you more info if you need it (mailto:john.gonzales@ahtsolutions.com).

Which development in San Diego did you purchase a new home?

bsd,

Check these out

http://www.smarthome.com/7603.html

I use them in my home as do some other members of this forum. I believe they meet all of your criteria. If you are interested, PM me, I'll give you some more info, and a source for purchasing them much cheaper.

Meeting your criteria:

1) These are B&W and have built in IR...They see ok in the dark as long as there is an object of sufficient size for the IR illuminators to bounce IR off of. In low light they are better. They have great resolution at 420 lines, much better than the 380 that most cheaper cameras offer. Smarthome doesn't offer them, but there is a version that comes in white for indoor use only.

2) These cameras have built in mic. The audio is superb. I have these mounted on the exterior of my home, and I can hear the neighbors down the street, their wind chimes, the kids playing in the backyard. At night I can hear the frogs and crickets at the pond about 100 yds back in the woods. For such an inexpensive camera, the audio is outstanding.

3) These cameras come with an included 60 ft cable. But the best part, if you open up the camera (easy, only two screws), the cable has an RJ14 connector and a terminal strip. Just use a single Cat-5 cable with an RJ14 crimped on the end, if you want to run your own cable. This cable provides video, audio, motion detection, IR illumination and power all in 6 conductors.

4) You can view the camera on any TV, VCR or any other device that accepts RCA composite inputs. The aforementioned cat-5 cable comes back to a small breakout box (included). Into this box, you plug in the 120VAC power transformer (included), and your RCA video and audio. You can also plug in a mic jack for picking up the motion signal. I'm using a Home Automation controller to switch cameras using the motion, but you can buy the VCR commander/camera controller with the camera(s) that will integrate the motion for your.

I did weeks of research on cameras, and this was by far the best bang for the buck and the most inclusive feature camera I could find. I've had them installed for a month now, and they have worked great.

Robertme,

Thanks for the help. I agree that these cameras seem a great bang for the buck.

What scares me is that I purchased a Philips B&W wireless camera set at Target a few months ago. It came with a camera that looks identical to the one you are talking about. I ended up returning the set because I could not get the range to exceed 12 inches in total darkness. For my "nannycam" type installation, this was useless to me. The camera looked good in low light, and great under lit conditions - however, I need the camera to be able to see ~15 feet in total darkness.

Otherwise, the setup sounds ideal - being able to use standard CAT 5 wiring, which will already be preinstalled in my house (and is also easy to add at this point) is a huge advantage. If a camera like this was available with good vision in total darkness, it would be perfect for my application.

John G,

Thanks for the help. I understand what you are explaining regarding using a multiplexer and several modulators (or a multi-unit), and I would be capable of installing and figuring this part out. Thanks for pointing out how to solve this.

I am confused, though, regarding the prewiring. Since I cannot seem to be able to find a camera that fits my needs (i.e. IR range of 15-20 feet in total darkness, audio), I can't yet figure out exactly what wires I would use to transmit and/or power through the house (i.e. between the camera and hub).

You mention RG-59 several times, including "simese RG-59". My "standard" wiring choices are Cat5 and RG6 (i.e. I can easily specify these through the builder). This may be a dumb quesiton, but: Am I safe in assuming that RG6 will suffice for any coax needs? Or would there be some applications where RG-59 would be required instead?

So, to cover my potential camera choices, what pre-wires should I have in each room that is to have a camera? Would a single RG6 and Cat5 outlet in each of the "camera" rooms suffice for any potential camera application? Or, as in one of your examples, might I need in some cases two RG6 connections (i.e. one for video and one for audio)?

How many of each (i.e. Cat5 and RG6) should I get in each room that might have a camera? Personally, I don't might "overdoing it" at this point and ending up with "too many" cable runs per room - who knows what I might end up wanting them for in the future.

Thanks for your help!

bsd,

I've seen the phillips cameras as Radio Shack sells them also. They are not the same, but in that I have never used the phillips, I can't compare their performance. As far as wanting to see 15' in complete darkness, you'll need a pretty strong IR flood in the room. You can purchase IR floods for that purpose. You'll likely come out ahead going that route, vs trying to find a camera with an integrated IR flood of that power.

As far as your other reply, and what cables to run, You might want to consider at the least one RG6, one cat-5e and one 2 conductor 18awg. RG6 is fine as a replacement for RG-59, and it gives you the added benefit if you go with a camera that has a built in RF modulator, of carrying the signal better than RG-59. In my home, I pre-wired three locations. I ran one RG6 and one Cat-5e. Many members will recommend running an 18-2 also for power. I decided that if I needed to have remote power, it would likely be on a camera that used coax for video/audio and so I would double up on the conductors in the cat-5 and use it for the power feed. On retrospect, I probably would also run an 18-2 just to be safe.

Good Luck

Glad to hear. We don't install cameras with audio so we wouldn't be able to do much more than advise anyway. Like I said, feel free to e-mail or call if you have any questions. I can be reached at 858 518-5772.

Every cable has a purpose and there are differences between the RG-6 being mentioned and the RG-59 that I described. RG-6 will work, what I described is a better choice. If you're willing to overkill, then run 2 Cat5, 2 RG-6. Video should be transmitted along 1 coaxial cable, audio down the other coax, power through the cat5. You'll have an extra cat5 in case your camera transmits audio or video down the cat5.

Thanks, all, for your help.

I contacted Channel Vision Technology, as they have both B&W and Color cameras that have IR and can see 20 feet in the dark, regarding the lack fo sound, and they replied that they sell a microphone option that can be used with any of their cameras (part number 5104-mic). I'm still checking regarding what kind of an attachment this is (i.e. does it need power, is the connection RCA like their cameras, etc.), but it should be a good solution (particularly as in my application the mic does not necessarily need to be physically located on the camera.

So, it seems that as long as I have two Cat5 and two RG6 in each location that I want to have a camera, I should have the flexibility to pretty much install any camera setup. I will need to do the modulation and multiplexing at a central location, which means that I need to send the camera signals most likely across RG6, with a separate cable each for video and audio. Is it easy and straightforward to use RG6 to make such "RCA" type connections? Would it be better to figure out a way to use the Cat5?
post #16 of 19
RG6 connection will be the less expensive video distribution method to work with. Cat5 will require the use of baluns ($25-$50).

Have the trim crew put F-ends on all of the cables. At the camera end you will probably use an F->BNC converter (~$2), and at the distribution end, you'll use an F->RCA converter (~$2). Use good quality Y-adapters to feed to the modulator and multiplexer. Make sure the Y-adapters are long enough, and make sure the y-adapter cables are flexible. Depending on the size of the mouting box, you may end up putting a lot of tension on the wires which is a bad thing.
post #17 of 19
The two converters I mentioned above screw right onto the F-end. One end will look like the 'ANT IN' fitting on your VCR, the other end will be either BNC or RCA. They're very easy to put on.

John G,

Thanks again for the advice. I didn't realize that RCA-to-RG6 was so easy.

I got feedback on the connections used by the cameras and mic that I mentioned (I am likely to use these):

"the 6124/5124 or all cams need a RG-59/OR RG-6 2 conductor for power......the 5104 mic reqiures 2 conductor for power and two conductor for audio"

Using an AC adapter, and plugging into a wall outlet in the room, in order to power the cameras and mics is fine with me - especially since I will not have 2 conductor cables for power installed. I'm assuming that this would be straightforward. I'm a little confused regarding the "two conductor for audio".

The cameras are not modulated, which is fine (I will need to modulate at the hub).

Thread Starter 
Does anyone have a recommended portable TV to use for this type of application? I will often use my standard TV's to access the camera signals (this is why I want to modulate the signal). However, there will be a couple of places in the house where it would be nice to simply set a portable TV that would be used only as a monitor for the cameras.

I'd like something that is portable (i.e. LCD), but with relatively large screen. I was looking at the Casio DV-4500, which seems ideal to me. However, it does not have a plug for an external antenna, and it's tuner does not go into the higher channel ranges (where I would have vacant channels to modulate to). It does have an AV input, but again I am planning on modulating. I guess I could rig up a wire connection from the RG6 to the telescoping antenna, but that would not be very clean.

Does anyone know of a simlar set that has an easier way to connect from the in-house RG6 (i.e. the modulated signal), and also has a tuner that runs up to higher channels (the DV-4500 maxes out at channel 69)?
