Why don't you want a potential thief to know your car is under video surveillance ??? Any person in your neighborhood that see's the camera and the signs up in your car would most likely be happy that there is video surveillance in the neighborhood , unless they are the perp ! It may also provoke the neighbors to be more aware of what's going on and maybe install surveillance of their own increasing everyone's chances of catching someone ! I would make it completely obvious that my car was being recorded including putting a sign or two in the vehicle !!! Even if I was not recording the vehicle .i would still put recording signs in the car .that alone would deter most random acts of mischief .if you had video of the person who broke into your car and showed it to the detective ,unless he immediately recognized the perp, he is not going to search thru 1000s of mugshots to find someone who has merely broken into your car. I think prevention is better than dealing with the aftermath of vandalism and hoping the cops can get the perp !!!

Do they make an hd-sdi version ?

Does that mean you have to install a splitter on the hd-cvi output of the camera to the dvr ? If that is even possible How do you split the signal ?

I think 2. 8 channel hd-cvi hvr's would be perfect . That way you can have up to 8 hd-cvi cams and 2 ip cams at both locations .that would give you a tremendous amount of camera's to choose from .plus you said that there were other potential out buildings so there is room for expansion and you probably won't have to be concerned about cable distance since hd-cvi can go up to 1500' .judging by the amount of cable on your estimate ,there must be many long cable runs unless they were charging you for spools of siamese cable that they were going to keep !!! hd-cvi gives you up to 30 fps which to me is one of the most important spec.the fastest hd-tvi systems that I have come across doing research say real time recording at 16 fps .I know ,30 fps gobbles up hard drive space bUT terabytes are so cheap these days and not every cam needs to be set at 30 fps.1. 4tb drive in each recorder with cams set to motion will give you several weeks or more of storage .depending on the activity level at your church and you can always add another hard drive later on if needed . Then with one app you can view all cams at both locations on one screen on your phone ,tablet , etc. I like to use Google Earth when designing a setup like your doing .it gives you a clear aerial view of your location and may help you pick better cam locations.plus you can use it to measure distances from cam location to your coverage area which will help make better camera choices and lens selections . I print several aerial photos and draw up the camera layout on the pix. The website of my supply house on long Island has an extensive selection of everything you need and their prices are the best I have found anywhere .you can use the site to get a rough idea of the costs of equipment and to compare specs .not sure if I can post it without getting in trouble .I am not affiliated with them in any way . 123securityproduct.com .sorry in advance if I pissed anyone off .your best bet in my opinion as a DIYer is to find a local supply house to purchase from ,that way you can see ,touch and ask questions .easier for returns ,exchanges ,and warranty issues too .remember though ,most of these guys are salesmen and not installers .some supply houses have system designers to help you . It's not easy comparing equipment from one supply house to another because there are a few universal brands and then most supply houses have several companies that rebadge or rebrand their products and put the supply house's brand on them .my supply houses brand is cantek and some stuff is made for them from dahua branded cantek .but because it says cantek doesn't mean it's a dahua product .

I think the reason for the 2 dvrs is because you have 2 separate buildings . It says 2x8ch hd dvr's but it looks like a 4 and an 8 From the way I understand this , the big question is How will a do it yourself er get siamese or cat5 cabling from one building to the other ? Is there buried conduit with enough room for more wire ? Is there a spare conduit ? Good luck ! Will the cabling have to be run aerial from building to building ? How far apart are the buildings ? Is there a driveway between the buildings? Is there Internet at both buildings ? Can this be accomplished by the average DIYer ? No offense meant to you or your ability as a diyer Sometimes 2 dvrs cost more up front but may be cheaper in the long run ! ! !

Hey mowbs , It's been a while and I know this thread is a bit outdated but I had to add another 2 cents. I installed an hd-SD I system at my brother in laws church in may 2014 .all cameras and DVD are still working fine . The DVR and cams are all dahua equipment rebadged as cantek for my local supply house .they are all made in China. The daytime video is very good on all cams and the nighttime video is very good on some cams but not on all .I added a few more cams over the summer but my supply house didn't have any more of the same turret or open faced dome cams that I originally installed due to the uprising of hdcvi, hdtvi, and add. It seems like dahua was abandoning hd-sdi for hdcvi . However , my supply house did have some hd-sdi varifocal turret cams that were rebadged as cantek from another manufacturer which I do not know the name of .they look exactly like the cams I originally purchased and the supply guy told me they were a little better than my originals .after installing them it was immediately clear that they were much better .also the nighttime video was much better .the only thing I do know that was different was that these new cams were made in KOREA not China. Had I known ,I would have purchased these the first time .the original cams from China were about $115 each .the Korean cams were originally about $150 each .since the supply house was liquidating hd-sdi cams , I got them for about $40 each . Right out of the box with no tweaking they were just how I thought a 1080p video should look . Day or night I may be wrong but from my experience, My advice is to look for the cams made in Korea !!!

Im installing an 8 channel hd-cvi system next week and the customer wants 1 camera on the back of a detached garage approximately 25' away from the residence . there is no way to go underground because of a large cement patio between the house and garage . aerial is not an option . electric is direct buried under the patio . so my question is , is it possible to send the hd-cvi camera output signal wirelessly from the garage to the house and then hardwire to the dvr ? if not , is this possible with hd-sdi ? the only wireless experience I have is connecting my laptop to wifi

hello , and welcome aboard .

im pretty sure hd-cvi is fairly new news . hi def resolution , DIY plug and play install . AND WAY LESS EXPENSIVE THAN IP ! for most homeowners its a no brainer . unless that homeowner is a computer/ip geek on a mission to test his skills .

great idea milkisbad " title="Applause" /> . dahua has cvi hybrids (hvr or tri-brid dvr)available at my local supply house . but they only have 16 channel . cost more than double the original 8 ch. dvr . customer may not like that . dahua makes an 8 and a 4 ch. tri-brid too . just not available at my supply house yet . they do have ubiquiti products too but some of the posts I read here say ubiquiti products are garbage . not sure if it was all products or some isolated few .

the electric and tel iw are direct buried under cement . no conduit

thank you very much ! there is a telephone wire going to the garage and of coarse the yellow/black pair is spare . I wonder how the hd-cvi signal will hold up over 50' of standard iw and balun's . I know cvi is best with solid core rg59 or 6 . maybe sdi will hold up better ?

thanks ak357 ! does anyone know if it is possible to take an hd-sdi camera's output signal and send it wirelessly then hardwire it to the dvr ? ?

did the hard drive stop working ? have you been able to get the dvr to record again since the trouble ? check the user log and see if someone accessed the dvr around the time it stopped recording . aka inside job . even if you think no one else has access . hence , the importance of keeping passwords secret and setting up separate user accounts and administrative accounts .

BEWARE OF THE "ALL IN ONE BOX" SYSTEMS ! I cant find the focal lenth of the cam's . I cant find a record rate of the dvr . I think you are setting yourself up for possible failure. i don't think that 12 of the same cam's would be a smart choice unless they are varifocal cam's . every camera location will have a different demand whether it be distance , backlight , weather , angle , location , vandals etc ... so 12 identical fixed bullet cams may limit your camera locations . the cables included with these systems are usually garbage too. you can get an 8 ch hd-cvi 1080p hi-def dvr with 2 or 3 hd-cvi 1080p cam's for your choke point(s) and 5 or 6 720p cams for quality general observation . take measurements from ideal mounting locations and use a fov (field of view) calculator to determine the correct mm lens needed then purchase the correct lens for the camera type(turret,dome,bullet). you will end up with a much better job and a much better system as well as staying close to budget and a happier customer .your customer will have a system that works instead of just having a system ! btw , cat 5e is not recommended for hd cvi. most quality 16 channel hd-sdi dvr's are over your budget but an 8 channel hd-cvi dvr in each building may fall under budget .

some of the hd-sdi cam's I recently installed were not too impressive either at night. I noticed that the vandal proof domes with the clear bubble over them are very grainy or noisy at night but the open faced domes or turret cam's are much better . especially where the incandescent lighting is good . some of my sdi turret cam's record in color at night and the video remains sharp because the lighting is good .

the Samsung dvr is old news and the everfocus dvr is not far behind . both of these dvr's will lock you into using standard definition camera's . I would take a good look at your hi def options . you should consider hd-sdi . like the ctw-dvr608hdsdi/1.5u would be a reasonably priced good quality hd-sdi dvr . as far as cam's. ctw-hdir43/2812 varifocal bullet or ctw-hdd142/2812 varifocal turret. if your budget is tight or tighter than hd-sdi . you can still get hi def with a hd-cvi system . 1080p hd-cvi is a little less expensive than hd-sdi but 720p hd-cvi is about half the price of hd-sdi and less expensive than everything you were looking at . also at least double the resolution .

you can buy any cctv system except an ip system to work over coax .its not the end of the world . if your looking to save money then you made the right choice . ip systems tend to be more expensive . however I would NOT recommend any "all in one box" system typically found at Costco and the like . besides the obvious quality , reliability and tech support issue's , these systems typically come with 4,8 or 16 of the same exact camera's . I have never designed a system with 4,8,or 16 of the same camera's . most installs require several different camera styles and lenses because each camera location will have a different requirement . an hd-sdi 1080p dvr and cams would probably give you the best recording but the most expensive of your options . an hd-cvi dvr and cams will save you a lot of money especially a 720p set-up while still giving you a very good recording especially if you use the right camera and lens at each location. then there is good old fashion analog which when installed and set-up correctly can do a pretty good job but with the price of hd-cvi , analog cant compete . i do not know if your contractor has any system design experience so you may want to get varifocal camera's instead of fixed focus cam's to compensate for that . 2.8mm-12mm should be fine . your last and possibly best option is to get a 16 channel tribrid dvr and 8 hd-cvi cam's . then you can get your security up and working under budget . take some time and figure out if you need any more cam's . if so , now you can get hd-cvi or ip camera's because you will need more wiring anyway . sales floor cam's are important but theft also comes from employees so you will need stock room cam's too. and a dvr with POS capability would be an smart choice .

hybrids and tribrids are backwards compatable on the analog side . meaning they work with 960h , D1 etc. the only thing backwards compatable about hd-cvi is that if you have an hd-cvi 1080p dvr , it will work with hd-cvi 720p camera's . but if you have a 720p hd-cvi dvr , you can only use 720p hd-cvi camera's . as far as I know , dahua is the inventor and sole mfg. of hd-cvi hardware . although you can find hd-cvi equipment with different brand names on them , they are all made by dahua . and as far as I know , hikvision is the inventor and sole mfg. of hd-tvi hardware , which is also available with different brand names but are only mfg. by hikvision . as far as recorded picture quality goes , I do not know if sdi has any advantage over cvi or tvi . that is what I was searching for when I found this post. symphony , if certain equipment availability and price deter you locally , why not order what you really want or need online . I know 123security offers dahua sdi and cvi products under their house brand name (cantek) and free shipping as well as very competitive pricing .

has anyone heard of a new dvr coming out soon called the magic Quattro all hybrid dvr which will soon be available from powertech. wondering if it will be ip,sdi,960h and cvi or tvi ?

welcome !

check out hd-cvi from dahua . it seems like you get the most bang for your buck .
