Not sure what the problem would be here the distances and most importantly the line of sight should all be good (assuming nobody is transmitting with similar frequency in the path). Whether a video cable has an F, RCA or BNC connector on it should not matter either as long as you have adapters or crimp/solder on appropriate connectors. It is possible that the cheap device wont push the video signal out 100 meters, I would take his word on it and move to another wireless TX/RX device, it looks cheap anyway. So yes a video amplifier would work but would be better to go with a device that didnt need it.

nvr v3.0

The ACTI NVR3 may be enough for you and you will be able to upgrade to one of the brands you mentioned if you dont like it. This assumes though you go with all ACTI cameras or the few other brands and models they support. Why dont you try one of their cameras and test it out and see what you think. If you are going with proper brands Im sure you can work with a distributor that would take it back if you feel you need something different, especially if you buy the replacements from them. You could also demo the other software in the meantime too.

The power supply stays inside and the output of that power supply is run to the camera. There are several types of cable that can be used to do this from cat5, coax with an attached power lead. In the description of the link you posted shows this: 1 x 60ft BNC video/power Camera Cable

[quote="bass1176" the technology has improved enough to trust these packages for quality. Your thoughts on any of the new lines that are selling in the Costco market. One problem is these systems are all fairly new and are just not time tested. I see a lot of people giving feedback on stuff that they have owned for weeks and give a good recommendation. Will be interested to see how they hold up after a year of being outside being beaten by the sun and weather.

I love this. I've been a contractor for 11 years, and people think theirs is the only knowledge or labor that has value! Whether its right or not people only want to pay for something they can see and touch. Now that people can look up prices on the Internet for just about anything and also learn how to perform an otherwise complicated task they value labor, overhead, pro licenses et al even less. Isnt it great now a guy can do a brake job on his car because he watched a 5min video on youtube and found some cheap chinese rotors and pads on the web to replace them.

The problem with upgrading a PC is there is usually very little room for a noticeable improvement. It really depends on the motherboard used as to what can be upgraded. You are limited to the CPU socket for which chips will be able to add to it. This will be also limited by the most recent BIOS that has been written for that board as to what is the max CPU you can add. RAM will also be dependent on how much can be added. If using winXP you will be limited to under 4GB, cant remember the exact number (3.X GB), but I bet you can even go near that due to the motherboards bios limitation. Some bios even have a HD limitation as well and it may not be obvious until you reach a certain amount. In this case put your money towards the next PC. That PC would be light duty at best even for a web use and would think that HD video would bog it down too much.

Ethernet spec says the max length is 100 meters which is nearly 330 feet. So 250' should not be an issue.

Since this is composite video feel free to adapt to whatever connector you wish: F, RCA, BNC. For example you could go to just about any hardware store and buy a wall plate that has an F splice (refered to as F-81) connection on it. Thats what I was suggesting is that the TV has RCA, the DVR has BNC. At the wall plate it could be an F to F (barrel). So either use a tool to put the appropriate ends on each end or buy adapters like F to RCA, or F to BNC, BNC to RCA etc.

A wall plate is just a splice so yes of course you can do that. You could also put a male RCA connector on the end of the cable behind the wall plate. An RCA connector will will be more commonly found on "consumer" model TVs. It also may be more common to find RCA pass through wall plates than BNC. Or use adapters, you choice.

CCTV cable uses an 18awg power lead which should be good for 12vdc or 24vac at 200'.

Do the deals go down in the driveway or inside his house? Doesnt seem like it would be evidence if you just see them go in the house and leave. Have you consulted police whether they would want this kind of evidence? Seems like if it was clear evidence and he would be tried on it, wouldnt his lawyer get to see it and then he would be obvious that it came from your yard/house.

It sure sounds like the cable. Premade cables usually are constructed with very poor or minimal shielding. Cable can come in a variety of shielding like quad, which will have 2 layers of foil and 2 layers of braiding. Typically there will just be one layer of foil and a percentage of braiding like "60-100%". Premade cables sometimes just have a layer of foil which can be easy to tear if the cable is put into a bind. So when you wiggle it you put it in a bind in another direction you are making the connection again and see good images. Of course bad connections could be in the connector as well from loose center or outer conductors. Cheap cable without significant shielding can be tough to reliably attach a new connector to.

all you need to look for is a hybrid NVR then you can still use your existing cameras and cables. Or you can buy an "encoder" that accepts analog input and outputs as IP. To use with an NVR it would have to be supported by the maker of the NVR or the software in a PC based NVR/VMS/CMS. This would be a case where you have a really high quality analog camera that is getting the job done and just isnt worth replacing. Encoders come in single input or even quad input or more.

A lot of POE switches have fairly low wattage available overall are you sure you are not over budget? Will they work if they are all hooked up on short jumpers near the switch.

hi at 10% there is just no money in it. you will then loose money. your biggest problem is she has no experience of sales ........ or design. Thats what I thought, how do arrive at the $1600 for 4Ch, is that labor only? Assuming you make additional money elsewhere per install. As for her income realistically how many systems would you expect her to sell vs the number of hours she will put into it. Also would you be compensating or providing the vehicle for doing the calls. Would she be still working full or part time elsewhere? At least with her minimum wage job she has a guaranteed amount of money coming in.

The main difference in RG6 vs RG59 is RG6 has a thicker center conductor as well as the overall cable is slightly thicker. When using either or you want to make sure you buy connectors that is meant for the cable. You would use RG6 for longer distance cables but in the case of CCTV this is many hundred feet. As mentioned under 750 you should be fine. What you need to pay attention to whether the coax is meant for CCTV which would be a "video" grade cable. This will be solid all copper center conductor and with quality cable the outer sheilding will be made up of copper too. Coax made for TV will not typically have a solid copper center conductor. However coax meant for modern satellite dishes WILL have a copper center conductor as its meant to carry power. Coax for sat or cable will almost never have copper braiding. Coax for sat/cable will only be RG59 if the length is very short like with a jumper.

I think if you cherry pick enough threads or posts from this forum you would think that Dahua, or Aviglon are currently the greatest brands ever. Kind of like if you cherry picked from a few years ago CNB would be the greatest analog camera ever made. You just dont see as much discussion about other brands by comparison. Or it was just a troll post???

Just to clarify on the FPS on DVRs some will list the total FPS on all its channels and some may give this on each channel assuming it would be filled. It looks like they are saying the Dahua one would do 30fps per channel for all channels so 120fps. It looks like they are advertising the DW as doing 120fps BUT it has 8 inputs so max would be 15fps on all channels. However if you had only 4 cams and wanted 30fps you could do that with the DW. Having said that do you realize that depending on the speed of objects moving through a camera shot that it may be very little difference in 30fps vs 15fps. Below 7fps or so is about where you will see a difference in motion of people for example. Recording at such high frame rates even at D1 will not give you much archive time too. Check this video out for a FPS comparison:

It didn't came with any power adapter. Just the camera itself. Maybe a "OEM" version? As far as I know, we should only use 48V with active POE, not passive POE right? I just know I had a TPlink a while back that had a 48vdc adapter and was even labeled as such by the DC jack. It may be that if you use a 12vdc the device doesnt turn on and therefore send out power to your device. Mine had an LED that if I remember it would be one color with just the DC adapter plugged in and then switch to another color when you connected a camera load on it. Unless they are not following spec of POE you should be able to use 48vdc and the device will regulate it to whatever voltage(s) it needs internally.

What do you mean compatible with loop outputs? A loop through would be something you would find typically on analog inputs where beside an input is also a "loop through" connection so that you dont have to use a splitter before the DVR. The BNC inputs on a DVR would be the same as a composite (yellow RCA) input on any monitor. The loop through could feed a redundant DVR or individual leads could be fed to monitors. With IP you dont have loop throughs since you cascade your own connections through networking switches. So a computer or computers would need to be used to display seperate camera feeds. Depending on how many graphics adapters you have on a PC would determine how many live feeds you could pull up.

Do you have the original AC adapter that came with it? It probably should be a 48vdc rather than 12vdc.

I see posts like this here and there and always expect it to be followed up with a non Chinese brand but it never does???

I know of some cable TV equipment that would do it but could cost thousands per channel to do. It would be cheaper to completely start over with IP cameras. However if you wanted to feed many TVs like at a hotel it would be the way to go. You would need an SDI splitter which would feed your DVR and the other would feed an SDI to QAM modulator/encoder. QAM is the modulation that is used on cable TV systems to carry digital channels. All newer TVs made in the last several years would be able to display these channels. Not cheap but much less expensive solution would be to use what broadcasters use, something like this: http://www.blackmagicdesign.com/products/smartview/ Maybe somebody makes larger monitors, but these have loop throughs so you can feed the DVR and the displays.

If SC meant South Carolina then yes you should just spend the extra money for an outdoor rated cam. The newer model Acti OD cams should be cheap enough to just not have to worry about changing it out 1-2 years from now when the moisture finally compromises the housing and then sits there and electrolysis takes over.
