Frequently Asked Questions (FAQ)


Question:01. What is a DVR?

Question: 02. What is a Stand-alone DVR?

Answer: A Stand Alone DVR is an all in one unit, it consist of a cabinet (like a VCR) and inside all components, boards, power supplies, CPU and all DVR related components are manufactured on one board. On the one main board there are IC Chips which contain the operating and DVR software.

Question: 03. What is a network DVR?

Answer: A network DVR is a DVR that has a standard Ethernet connector on the back. These DVR's can plug right into you computer network. They can also plug right into a ADSL or cable modem. If you have a computer and you want to run both your DVR and your computer of your ADSL line you will need a Router or some high speed modems come with built in routers so you might have multiple ports on the back of your modem for multiple devices.

Question: 04. How do DVR motion sensor work?

Answer: DVR's detect motion by looking at the video pixels (little light and dark dots that make up the video picture). as the pixels change the DVR sees motion. DVR's have a "Mask" or over lay for each camera, the screen is divide up into many small boxes called cells. Each cell can be individually turned on or off to enable or disable motion detection in that cell. This allows a camera not to see normally moving objects Like tress or fans. Each camera also has a sensitivity level setting this controls the amount of change in motion before the systems triggers. All motion sensing is done in the DVR. the camera has nothing to do with motion sensing it just provides the video to the DVR because of this, most any camera will work with our DVR's.

Question: 05. How long can the DVR record video for?

Answer: All DVR's record to a Hard Disc. Each frame of video has a specific size (from 0.5Kb to 5KB for PC-Based DVRs and from 10kb to 15Kb for Stand Alone DVRs are typical) one second of video can be made from one digital picture (1fps) to 30 digital pictures (30fps) The video we see on TV,s is 30fps so how long you can record for depends on how your settings are set on the DVR. Typically in security applications we look for 4fps to see things like people walking down hallways in and out offices or rooms. We use 7.5fps for better streaming video. This might be for watching peoples hand movements, cash draws or faster moving objects like capturing cars license plates. 15fps per camera is for "Like live video recording" almost perfect video streaming. And at the top of streaming video list is 30fps which is live streaming video, like a TV Program. Customers who demand the absolute best chose these DVRs We sell many of these DVRs to Police stations, the Military, Government Building, institutions and Casinos. Here is an example of how long you can record Example: recording at 4fps on a system with an image size of 12kb would be 12kb*4=48k per second. if you have four cameras then 48k *4=192k per second. One hour would use this much space 192k *60(miniute)*60(hour) = 691200k (per hour) or .69 GB so if you have a 80 GB hard disk 80/.69 =115.94 hours = 4.8 days

Question: 06. Can I review recorded video and keep recording at the same time?

Answer: It depends, this feature is called Duplex, you can review reordered video (what happened yesterday) and continue recording the live events. None duplex machines will have to stop recording to go back and view previously recorder video these machines are called simplex. our PC Based DVR series are Duplex and Triplex which means you can keep recording while playing back Pre-recorded video and also keep recording while reviewing or playing back video over the internet.

Question: 07. What is the warranty of the DVR?

Answer: Our product covered by warranty for one (1) year for parts and labour. Excluding transportation expense and shipment charge if applicable. - This warranty does not cover any damage due to accident, misuse, abuse, mishandling, neglect, improper line voltage, faulty electrical circuit, or damage caused by fire, flood, earthquake, and other natural and social calamities or acts of God. - This warranty will be voided if the product has been tampered with or repaired by anyone other than by Votek Digital.

Question: 08. What kind of broadband internet line do I need to view my cameras remotely?

Answer: It is best to have a high speed internet connection (ADSL, DSL, ISDN, T1 or Cable modem) with a static IP address. A static IP address is a specific electronic identification number that identifies your specific machine when you sign on the internet you are assigned a new IP address each time (dynamic IP address) this makes it cumbersome to know what your IP address is and you would have to look it up each time you got on the net to connect to your cameras. With a static IP address, you can just program that number in once and that is it. Then just push a button and you?re on the net.

Question: 09. How can I save or Archive recorded video I want to keep?

Answer: For A Network Stand-Alone DVRs The easiest way to backup the recorded video is by using a PC over LAN. PC-Based DVR's have CD-Burners this saves your video as an AVI file on a CD Disc. Most PC-Based DVR's can be upgraded to DVD Burners but, this is expensive and the DVD discs are also expensive.

Question:What are the benefits of having a CCTV system?

Question: What is "Real Time" recording?


What are real-time images?
Real time images are those images that are being transmitted as they happen, not to be confused with real motion. Unfortunately, the words real time and real motion are used synonymously within the industry. Just because something is real-time, does not mean it is real motion.

What is real motion?
Real motion is video that when viewed looks natural and has no jerky motions of any kind whatsoever. Don't be confused by real motion vs. near real motion or real time.

How many frames does it take to give a real motion look?
Industry standards typically speak of 30 frames per second as real motion video. Think of frames per second in terms of how a cartoon is made with cells or even think of the projector in a movie theatre where multiple frames pass in front of the lamp to give the appearance of "real motion".

Question: What is unique about the Votek DVR System?

Answer: The Votek DVR is a digital video recording solution that provides H.264 Hardware based compression. After compression, the video is stored on hard drives, which can be accessed by multiple view stations over the LAN or WAN.

Question: What is significant about H.264

Answer: H.264 compression has incorporated proprietary algorithms optimized for CCTV. This technique provides variable bit rate recording and "Real Time" video compression for all cameras without compromising frames, quality or resolution. Software compression also allows Votek DVR to save storage media versus other compression methods. Another inherent benefit of Hardware compression is the ability to upgrade allowing for continuous improvements and new features.

Question: What are the benefits of variable bit rate?

Answer: Variable bit rate recording is achieved by Votek PC-DVR Systems 's use of the most sophisticated Digital Signal Processors currently available. H.264's variable bit rate ultimately benefits end users by providing complete information. When action or detail is increased in the video scene, the variable bit rate automatically increases to provide you with quality video without the loss of valuable information, frames or resolution. When there is little or no change in the video stream, storage requirements are reduced by the automatic lowering of the bit rate.

Question: What is the Average disk sizes required for 14 and 31 days storage for 4 and 8 cameras?

Answer: An average disk size is shown in the table below. For average calculation we presume that camera settings are: color mode, 768x288 resolution, 3 frames per second, office activity (30-40% through the 24h). -> 4 cams - 14 days = 30 Gb - 31 days = 70 Gb -> 8 cams - 14 days = 60 Gb - 31 days = 140 Gb

Question: Does the number of cameras connected affect the storage capacity?

Answer: No, it is the number of images recorded based upon the frame rate that affects the storage capacity.

Question: How many cameras can be connected to a Votek DVR?

Answer: The Votek PC-DVR can be supplied in 4, 8, 12, 16, 32 and 64 camera configurations.

Question: When someone is viewing live images remotely, does it affect recording speed?

Answer: No
