CCTV_Suppliers has given some interesting advice but I disagree with "Here is a suggestion if I may... Why don't you call a meeting with this neighbor of yours and have a private discussion"....... If you do pursue any kind of arbitration make sure that you do not do it in a "private" setting....go the legal path ... use a court appointed impartial referee agreed to by both parties who then is empowered to use authoritative judgment a so called quasi hearing and determination of your dispute. Since this is a long standind problem I would be very careful about contacting or approaching the person you are having the problems with, Ive seen in the past how such contacts can turn ugly with counter claims of harrasment and threats. Most courts and law enforcement frown upon these types of contacts after the fact which often lead to wasted court time the disputes/confrontations end up with a lot of back and forth bickering in some cases even turns to violence.

You maybe able to bypass the lawyers and bottom feeders if you have the suspect tampering with or stealing mail....contact your local postmaster and have them notify the regional postal inspector service and turn over your evidence to them.

The Bosch 11258VSR Concrete Drill (1.4 foot-pounds of impact force 4.8 amp motor) is my favorite for around the yard but if you are doin bores/core drillin steady on the job we always went with wet (water cool diamond bits) for box work....missed knockouts punch work, anchors, dowels etc on utility duct bank and buried precast.. CS Unitec (http://www.csunitec.com/drills/coredrill.html )has some durable gear....

As you are ICU nurse Im sure you understand the importance of using reliable field tested equipment that you can depend on as well have good insight in the use and performance of any device (be it a heart monitor or a cctv camera/dvr) that being said most products will peform based on two thoughts #1 the quality of the devices and #2 the install of the devices.... a good start before you purchase and setup any system is to first on paper work up a complete design layout, area to be covered, devices, power- specs locations and then research all methods of image retrieval for evidence in the event needed for legal action. If you are going to go the budget route before you invest a lot of time and money I would suggest you purchase only one device (start with a cam) and try it out see if you are satisfied with the image result on a local monitor before you get a complete system. A cctv system like any other electronic system can be measured by the sum of its parts with correct electrical install and attention to detail more so with outdoor applications. Beware of typical "plug and play" off the shelf setups, better to design a quality system that will fit your needs and that you can count on and maintain. There is a wealth of info on the web from basic to advanced learning curves on cctv technology and install (codes-safety etc) just be wary of retail-selling specs and hype on performance. Good luck-good health.

The truck and trailer built better than the canopy and support columns. but Im sure the architect /engineer would say it was designed to break away.

in order for your set up to work you have to bypass the digital boxes in simple terms the cable/HD boxes work from specific channel usally 2 or 3 then the channel selection is controlled from within the digital box out board controller, your modulators will be on the analog side so either you switch between the digital and standard basic cable channel by hard wire two inputs into your boxes or one dedicated to your tv (if they have two inputs) the motorola HD DVR boxes out here have that option or if you have a a tv set that has dual tuners (such as the older sony wega lcds have) then you can split screens one for security view at the press of a button or whenever you choose to view etc. Or you can switch bettween the digital box and control the tv with its own remote and by pass the box but that is a pain, There are work arounds with more money such as using the digital set ups from Channel Vision but they are pricey for a multi box set up calling for purchase of several units. I have in the past on new work run two sets of cable to each set one for the digital service and one for the security mods and basic channel lineup, you also have to check your freq as some of the channels can overlap into the digital range and cause interference with your wider HD setups as the cable cos are using more and more info for the lines now days... it used to be simple now modulating takes more effort and design consideration to inject into the line but can be done.

Interesting, things to avoid in that video ...the outcome could have been tragic if there were other customers in the store note the way the clerk was blind fireing from the beneath the counter, he should have had the weapon holstered and practiced-train to draw and bead down on his intended target and the far reach for his firearm could have cost him his life, he was just lucky as well the 22cal although better than nothing often will maim and bounce around in a body giving a target more time to attack versus a solid hit with a man stopping caliber. Anyone who keeps a firearm for personal protection should be well versed in the use of the weapon and the legal ramifications that can follow with a innocent bystander wounded or killed in the discharge of the firearm be it in self defense or not.... constant practice and being aware of the limitations of the chosen weapon is the key to a good defensive stance in such circumstances. I am glad the clerk made it out alive.

Heat is released in three ways: conduction, convection, and radiation and all power converters - AC/DC, DC/DC and DC/AC consume power that is dissipated internally as heat."Heat" must be removed from power-dissipating components within a converter in order to stay within a functioning temperature as well other critical components keeping to a stable constant temperature. The Arrhenius equation for reliability indicates a power device failure rate increases 3 to 5 times for a 25°C rise in temperature. Its a good idea to bench all power supplies and check their specs/rating prior to applying in the field. Most failures Ive come across are from improper wire practice cable management and power related camera malfunction due to "plug a play" attitude that some "professionals" as well DIYers have when working with circuits (all voltage)

keemble one last thought, I try to give advice that is well grounded....was talkin to a buddy of mine (union mechanic) that does elevator work back east and I asked him about the noise issue you are getting, he told me that more than likely it is a ground loop - with car in motion and changing position the GROUND potential will vary, it seems to be a common problem with elevator installs, as well make sure none of the cabling got skinned and any exposed shield are contacting metal. Good luck....see ya Regards

Belden wire - (New Generation 533945 RG6 CCTV Coax CCTV Cable 18ga Solid Bare Copper Center Conductor - Foam polyolefin insulation 95% Bare Copper Braid Shield - PVC Jacket) you should be able to max out 1000ft any longer I think you will have to use a amplifier. The active UTP balun is powered - the passive is not, active will enable further distance. Your choice to use cable or UTP really depends on the install. For inbuilding, with a active balun you will need to power it. With the RG6 you can run direct to your monitor/DVR unless you find that the signal is dropping off then you will have to amp it. Your 2000ft length to camera is it on the same floor, did you layout a path, you should take into consideration all the cabling factors such as bends, etc before you decide on the method. The cable for the elevator as you described sounds correct: a stranded cable will be flexible to allow for movement, often the video output will travel along the exisiting "traveler" cables in the shaft to a junction terminal box sometimes located approx halfway up the shaft from there it often will be connected to standard solid cable then on to your monitor or security room. Some elevator cam installs use fiber or UTP Ive seen all three in new and old construction. It is difficult to troubleshoot your "noise" problem with the elevator cam without detailed description or onsite evaluation of your system, however start with your pwr supply, check all your cable paths, check voltages, check the actual connectors, if the cam is run to terminal box as I described then locate it and check the connection there too. I am heading out of town to my cancer center so wont be able to post any further for awhile.... perhaps other forum members can help you with other questions, there is a member here named survtech who has done extensive testing using baluns and has a lot of knowledge on their uses from his casino work, check the forum for his data and insights. Good Luck regards

Voltage rating of a fuse does not indicate the operational voltage of the fuse. The voltage rating determines the maximum voltage that will not jump the gap between the elements after the fuse has already blown. Its all about fire protection and safety, the fuse will operate at the rated voltage and any voltage below its rating. Always good to follow the manufacturer spec for required fuse replacement.

If the quality of your pic starts to degrade (darker image) in night - IR operation - ON- then step up to 1000 mA added draw for IR operation - as well consider drop for longer wire runs.

Chuck, If your going to use mulitple single PS for your cams (IR D/N 12V)go with 12VDC 1000mA UL listed - regulated. Dependent on your set up you may consider a single powr box to handle all three cams.

Look for "Regulated" printed on the label on the AC adapter from Radio Shack... to be sure test it. The "noise filter" noted, often with DC - output voltage of unregulated DC power adapters have a fairly significant AC "ripple voltage" (known as noise), that travels on top of the DC voltage component at the power adapter output. The "ripple voltage" can range from several milli-volts to a volt or more, the "filter" (or smoothing) capacitor across the positive (+) and negative (-) output of the power adapter (where the power output meets the input of the load). A capacitor value of 100µF to 470µF can typically reduce the ripple voltage by 50 to 90% or more. this is not TRUE regulation, the filter capacitor can provide some degree of increased voltage stability, during minor short term variations to load power requirements but best to seek a REGULATED PS as noted in the cam spec.

Maybe ground loop- do you get a clean signal during day operation,(its possible that you are not - just more visible during night operation) ground loops can be radom and highly unpredictable....A difference of a few millivolts can cause a ground loop. Also you state that you are powering cams from multiple PS make sure that all of them are working off a common ground. Are you using sub-standard cable (cheap/cable) often that can contribute to pic probs as well check you cable paths (UTP or Cable) if an AC magnetic field comes close to your cable.The AC field can induce a current into your cable and disrupt your video signal. If THIS is the problem and cabling path relocate does not solve the problem you can use a video isolation transformer to correct the signal disturbance, ground loops can be a bear to trace/find but they can be corrected not eliminated. This advice is not definitive...as other posters advised there maybe other sources of your problem or a combination of others...but from what you described sounds like a ground loop. Before you involve ground loop devices first check your ps locations, voltages, cable paths and any switching devices that operate at night nearby.

http://www.terminaltown.com/Pages/Page107.html pack of five 1.99 ....check your package/box the Napco boxes ship with spare fuses, if they are missing contact your seller.

I would agree with Survtech, if you are feeding the additonal monitors by way of a composite input ("video 1" as stated, most panels will have either a RCA or Svideo in) then use a distribution amplifier (powered - dependent on your distance) Vac has some reliable well built bricks, I use them with excellent results for multi-monitor set ups: http://www.vac-brick.com/ check out their CCTV products. I would avoid cheaper off the shelf dist/amps they often are problematic. If this is a not a dedicated system and you are going through cable tv then modulate if you wish to create a channel for viewing on all connected "tV' sets.

Hello northeastremote, after re-reading your original post...an after thought .... if you already have a contract with the police agency for the design/build and it is not stipulated to include such a device then you dont need to worry. (perhaps they use a "secure" isolated room for" for lawyer consult.)

A construction super I know gave me a heads up on the system....he told me the company involved was TranTech http://www.trantech-inc.com/ couldnt get any more info (contractual obligations) but there is info on the web refering to the system elements. Perhaps if you contact them direct they may offer some resources. as well here is link to a co that sells interview devices for PD : http://www.covert-systems.com/int_room/int_room.html cant vouch for them, I dont do that type of work but have in my past GF career worked on many county/state projects on the construction end for secure facilities and its hard to gain actual details from consults/design involving their inhouse security systems. You may want to source info from law enforcement publications and construction links regarding county/state local security projects put to bid or ongoing by region. Good luck....regards

First off I dont know where you are located but be careful with installing cams in elevators, there are many requirements to follow as well there can be other systems integrated with alarm panels for elevator recall tied to smoke/fire alarms etc.. you dont want to disturb other wire paths.. Most cam wire/cable is located in traveler cable, how is your camera installed? what type of connection are you using,is it flexible coax... where is your power source for the cam,is it off a power outlet in the cab ceiling on top of the cab... if you are getting noise when the elevator is is running I would suspect that you are getting induced power interference or perhaps ground issue....For your 2000 ft camera distance is it outdoor or inbuilding.. I would source out a active UTP balun: Nitek, NVT are popular there are many others...look at their websites and check out active (powered) solutions they also have instructions for aplication. What kind of cable is your RG6...hope its copper.

What is the total length of your run, distance to camera (s) in question? The UTP balun will enable you to use Cat5-6 in place of cable, there are many brands one such is Nitek http://www.nitek.net/apps.htm and by PRO I meant a high quality amp (in line) that amplifies as well equalizes the video signal.....sub-standard so called "cctv amps" often can be problematic and introduce more noise defeating the purpose. Equaliization of the video signal spectrum and not just amplification is the proper method. In order to correctly install cable compensation by means of a device you need to measure your total cabling distance. Then you can plot where to install the device. Either at the camera end or the monitor.... a potentiometer on higher end amps will have calibrated positions for meeting various cable lengths. There are methods/charts for setting the amount of amp/eq in relation to cable length but that is for another post/day..... regards

rg179u is for VGA or HDTV broadcast better to stick with either RG59 or 6 copper for your cctv work.... High quality RG6 copper with a pro amp get approx 4500 ft ... Ive found RG6 without a amp 1000 ft is pushing it to get a acceptable result dependent on the run/path with ideal circumstances, try to avoid joining cables to lengthen run (splices etc) on a new install unless you are doing a emergency repair, better to pull a complete line. Perhaps you may want to research using UTP with Baluns (active/passive)
