NationalSecurityTech.com has Megapixel lenses that provide backfocus with their box cameras, not all but some models. They also carry zoom auto-focus camera with RS485 for remote connection. The auto focus seems sensitive enough to adjust properly. They also recommend using the next size up lens for the box cameras. You can research 1/2" or 3/4" Megapixel lenses on a 1/3" camera. This will increase your depth of field. We use their test monitor that has a built in focus meter to dial in focus that works great for day and night shots.

camera under eves.. was it OK to use 4" electrical boxes?
varascope replied to jr219's topic in Installation Help and Accessories
Cameras rarely do. You will need the box space for your connectors and need to drill holes in your NEMA cover. Make sure to use silicon for the edges and heat shrink for your connectors. Dielectric gel is also good for the copper connectors. -
Welcome to the forum. You will find infrared is not just cut and dry. Each model can vary by: 1. Size of LEDs 2. Number of LEDs 3. Color temperature measures in nanometers 4. Built in IR vs External 5. LED vs Laser 6. Cameras IR response and IR cut filters. Many manufacturers uses the same housing but the insides can have tons of variances. Happy hunting.

As long as they are IP PTZ, no problem otherwise you need a capture card.

This is a perfect example of upgrading to an HD-SDI system. 1. You do not need to run new cables 2. If terminated properly, RG59 or RG6 cable will work 3. You have option from 720p, 1080i & 1080p cameras. 4. You can maintain 30fps or 60fps per channel The new CVI option is also available but currently provides 720p. I hope the word budget is not another word for cheap. You do get what you pay for. Invest in a good linear power supply, surge protection and UPS unit and your system should last a long time.

Ah the age old questions on formulating service contracts. Method 1: Value based If you are going to offer replacement of equipment. Estimate the likely hood during the contract period for a camera to go out. For 36 cameras, if warranty is expired I would estimate 3-4 cameras possibly going out during a year. Figure outdoor cameras are more likely to go out. For service assume the 3-4 you will need to truck roll. Average 4hr per call X your rate (discounted from hourly). Figure in truck rolls if 4hours will cover travel and distance to each. Will you provide bi-annual cleaning and inspection or similar? Figure the time required to perform that for 4 locations. I am guessing at 4 days times X hours. Method 2: System Cost percentage. This is typically used if you sold and installed the system and you know the quality of installation. Take the total cost of install and come up with a percentage 10%-22% typically of the total system and tier it across the length of the contract. 3 year contract is discounted over just a one year BUT at the 3rd year you are more likely to have service calls Method 3: Customer evaluation 1. Is the customer a whiner? 2. Can the customer program their own alarm clock? 3. Is the customer demanding? These factors need to be considered first. If a problem occurs, are they the type of customer that reboots first, tries a couple of things and then calls or do they call first and say the camera system is not working since the power went out in the neighborhood? Some see service contracts as "Im going to get ever dollars worth" out of you. Other issues are locations with high turnover. Training 4 managers in one year can be frustrating. Which ever one you decide, make sure you specify what IS include and what IS NOT included. Sometimes it is better to submit multiple proposals as it lets them decide the level of service. List 3 options, what is included and what is not explaining the NEXT package that does. This helps cover you if you are higher than the competition as it lists the Platinum level but yet shows if price is the factor, WHAT the customer is WILLING to live with.

1) Is there any software as dahua pss alternative ? YES. NST's CMS MkII software being released in February 2) Is there any possibility to connect synology SurveillanceStation to the Dahua DVR/NVR ? ( on synology SurveillanceStation I can only add cameras , but 4 cameras are connected to the nvr poe ports ). As far as I know NO, but you can connect to the cameras as well. Use the NVR locally while the SurveillanceStation records cameras remotely. Not sure on DVR only. 3) Is any way to add rtsp stream to synology dlna ? ( like in serviio ) Dahua RTSP requires an "In between" application like VLC, Wowza, etc to do conversions. You can try entering the Dahua RTSP stream and test if synlogy will accept it. 1 RTSP stream per camera.

Software for IPCam (Local IP Address for 32 Ch Live Viewing)
varascope replied to leemeng83's topic in IP/Megapixel Cameras and Software Solutions
Sounds like you want to setup user profiles and permissions, correct? Login to IE and see the required number of cameras but control viewing, playback, PTZ control and other functions is control by the administrator in setting up users or user groups. Until you choose a VMS, various VMS have limited browser based camera views around 16 cameras. Some can do more but typically a software client is needed to achieve this. The biggest issue with IP is you need bandwidth to the NVR to record and bandwidth outbound to view. Processing power also goes up based on number of users simultaneously, image size, frame rate, etc. As Beullwinkle mentioned you want a good server. I would recommend a dual processor with 32G of Ram. But remember your only as fast as your slowest connection! -
I think you need an example or specifics to your question. Ethernet is 100m/328ft until you need a repeater. A VMS can be onsite or across the globe. There are dozens of variables that can make or break an installation especially with IP. What is your idea you want to do? We can start from there.
-
Other thing is you may have a bum unit. Not impossible. When you see the logo, can you enter any menu? Try the front controls, not the remote. If using a mouse can you right click? Anything?
-
Check the menu for assigning cameras to matrix or loopout. You may not have any cameras assigned.

Dahua IP Cams Short Record
varascope replied to simontemplar's topic in IP/Megapixel Cameras and Software Solutions
Can you change Deveice Minumum free capcity to 768M? Then quick format the drive. D: is your 2TB drive? What model number is it? Was this drive in a Windows machine before installing or was it new out of the pack? -
NVR packages, any have idiot proof GUI with remote control?
varascope replied to drocer's topic in IP/Megapixel Cameras and Software Solutions
Browser access and mouse are the 2 top ways. Hopefully the browser has more functions for live view and playback which you wan the customer to familiarize themselves with. Customers usually can't handle more than one method. Admin settings hopefully they call you. We used to hand out manuals, paper, and leave next to the DVR. They still call 9 months later and ask how to burn. Probably 90% of all support calls. They get offended if you mentin the manual next to the DVR or the PDF they can download. On our end tons of time is spent "re-training" the customer. So next version of the software they included step by step instructions right on the screen. Step 1,2,3. Support calls for burning dropped to less then 10%. Tell the customers the remote is only for people used to older DVRs and have a hard time transitioning. The 12 oclock flashers (People who have their clocks and VHS players flashing 12 because they don't know how to change the time) Use programs like Snagit to create screen shot quick start guides and manuals. Pick one method and instill repetition is the only way for them to learn. Also coming from software development: The easier you make the software for the user to use, the harder and more expensive it is to program. Additional lines of code are needed to make it user friendly. From marketing perspective: You sell by price, you get what you pay for. The better class of customer that pays a little more for a better system generally has less issues. Selling to mom & pop shops generally turns into more support calls for you. -

Once you build a idiot proof NVR, they just build better idiots! -
Remote viewing works but not from 1 specific IP
varascope replied to kahall's topic in Computers/Networking
Does the brand of router/firewall happen to be a Sonicwall ? Also need clarification: 4G wireless obtains an outside IP gains access to either Bldg 1 or 2 using the Outside address? Correct When using Bldg1 wireless are you trying to connect through outside address or inside address? But you can browse the internet on Bldg1 Wireless? What is the subnet mask on both bldgs internal IP's? A most important when on Bldg1. Did you plug in a hardline to the network? On hard line can you get access to either? Is is isolated to wireless? PM me if information you provide is sensitive for open forum. -
Both statements are false. From following this post, I see many people are misinformed. 1. We have HD-SDI installation that have distances over several miles over fiber 2. It has RS485 for PTZ control 3. Capability for relays 4. Can also include ethernet and PSTN options In regards to mid-span what is difference in UTP at 328ft requiring a mid-span, switch etc??? How many companies want video traffic on their network? HD-SDI is point-point and if one goes down, ONLY 1 goes down. IP mid-span or switch goes down you typically lose a lot more cameras. Also RG59 will have reduced distance. RG6 is recommended. For professional installations using Belden 1694A which is rated to 4.5 Ghz can get you signal around 600ft. Costly but other ones are rated the same at about 35-45% less cost. Each job is different Therefore you have to design 2 estimates with a side-by-side pros and cons. Full 30fps or at least 24fps on large installations is compelling for 2.2MP. IP at the same rate depends on the number of cameras on one segment. I am not anti-IP but both have pros and cons. I just hate to see HD-SDI get a black mark because people are no properly informed.
-
Why do you say that? A 100 camera HD-SDI installation is still less than a "Properly installed" IP system and playback can be in real-time compared to reduced frame-rate IP. I would like if someone would post the purchase order for a large IP system, redacted of course, to compare what an HD-SDI system comparable would cost. A side-by-side comparison.

SYSTEM DESIGN FOR 120-CAMERA IP CCTV FOR HIGH SCHOOL
varascope replied to logitronics's topic in System Design
Quick questions: What MP rating? What bitrate are our planning? What frame rate are you planning on recording at? How many days of storage? You mentioned PTZ's what are the specs on those? Six buildings but how many cameras per building? Do you have a breakdown? Decoder? Encoder convert to IP, Decoder is taking IP and converting to HDMI, VGA etc. The IP stream is already encoded and stored on the NVR. Do you need spot monitors that need a decoding engine? Where are you deriving "Decoder" from? Was it in an RFP? Fiber optic converts to ethernet. What type of transceivers are you planning on using? Gigabit? 10G? What POE switches are you planning and most importantly IS THIS an independent network or shared? For this size it should be on it's own. Without exact measurements, maps and other information any response will be vague. Sounds like you need this professionally engineered due the magnitude and that is usually a charged service. Beware of people claiming they can do it. I can write a book on failed IP installations. There are people confident in networking but IP video is a different animal if you want it done correctly. Another issue, from experience with school systems, anything less than 15fps will cause evidence issues. A fight breaks out and your at 7fps, they won't like it. 21-24fps is recommended for schools and high value installations. Many people argue the frame rate issue because they think IP is the end all be all and can't admit it is not for everyone. There are reasons casinos, high security government facilities, nuclear and more use 30fps. You may want an alternative design using HD-SDI and you may find the cost is significantly less than IP, better frame rate and just as clear as IP. Remember think as a SECURITY Professional, not an IT Admin. -
1. Your focal point should not be much wider than a single car driveway 2. Angle should not be greater than 30 deegrees 3. Infrared needs to match your states color contrast. Different states use different color temperatures for best result. 4. Lighting must match focal distance If you are looking for a stationary plate capture the above should work. If you are looking for a "In motion capture" The camera should use a CCD sensor instead of CMOS Frame rate should be 30fps to 60fps and shutter speed above 2400. Does anyone know of a IP camera with CCD ? I know NST has a HD-SDI CCD high speed camera designed for LPR, Red light etc but the low end is $1150 They also have a speedbump cameras available in analog, HD-SDI and I think IP. The analog gets a great image as the focal point is right on top of it.

Sounds like an error in coding. Something is wrong with the refresh and/or draw rate. You could try to update your DirectDraw version. Check your video card settings for refresh performance. But I am still leaning towards error or compatabilty in coding.

Need advice about PELCO-D protocol compatible relay board
varascope replied to KMtronic's topic in Video Transmission/Control Devices
You could use the Auxillary set commands. 00 09 00 01 (to) 08 -
Settings> Compatiibilty View > Add IP address and accept. Refresh and you should be working. Nov 26th was the update that caused this issue.

What you are referring to is a tap. It is theoretically possible, Measure the voltage at the point of the tap, install a diode and possibly a capacitor to prevent voltage rush and if the IR has a low draw, it maybe possible.

Dahua IP Camera color code/pinout for the Ethernet
varascope replied to b44kwz's topic in IP/Megapixel Cameras and Software Solutions
Do continuity tests for each pin. Should take less than 5 minutes.
