Many customers always ask questions about how to make the DVR more efficient. A lot of these questions are related to recording space, motion detection and bandwidth.

Today I will write about some of the settings I consider the most important to make your DVR more efficient, from disc capacity, motion detection and quality of recording.

How many days you want to store?

Having an Idea of how many days you want to get from a security system is crucial, because it will determine how much space is required to accomplish your recording day goals.

I always picture the storage size I need based on the amount of cameras I am installing in the DVR, also where they are going to be installed. The reason for this is because having cameras installed in places where there is a lot of movement it means more storage will be used, therefore more space is required.

Another variable I will take into account is the resolution and how should I be recording in the DVR;  Fundamentally you have 2 options, based on motion or continuous record (24/7 non stop)

Motion Detection, Alarm and Continuous Recording

All of our DVRs have the capability of using different types of schedule recording. You can, in theory record using different methods depending of your needs, i.e you could configure your DVR to record on motion, continuous, at certain times, a combination of both or even when an external alarm is triggered if connected to the DVR.

Motion is the common type of recording that customers choose when setting up the DVR and this will be the best scenario when it comes to save space and achieve your goal.

You could also save more space by configuring the DVR to record only when alarms are triggered then have a camera activate video recording when these devices get triggered. This is ideal for areas that no one is supposed to be there, such as a private vault or an office, where they need to open a door or pass through an area that will force to activate the alarm contact. This is ONLY ideal for those cases where you don’t want people to know that you are recording and there are no camera or visible alarms.

Continuous recording are considered the most hard drive space consuming when it comes to saving space. The system will record regardless if there is any object in front of the camera or if a camera is connected physically to the DVR. This method on the other hand is used in specific areas such as banks and heavy pedestrian traffic.

How to avoid false motion detection events?

Many times you will get false motion detection creating empty files in your drive and when searching for events like this can be very difficult because they are just like regular motion events. To minimized these types of false motion events there are a few settings we can adjust to reduce false events.

Anti Dither:

Anti-dither is a feature that is been around for decades and its function is to delay a trigger. To explain this much better imagine that you are going to take a picture and you setup a timer in your camera. In CCTV when DVRs are configured by motions you can set each camera to have a delay when something is on front of it. By having this set to 5 seconds as a test, then the object that will eventually trigger motion needs to be on front of the camera or in frame for 5 seconds for the DVR to realize that there is something in there. After this threshold is met then the camera will activate its motion feature then it will start recording.

Sensitivity:

Sensitivity is a parameter that will help you adjust how the camera senses motion based on object size. The lower the sensitivity the bigger the object needs to be and also the closer it needs to be of the camera to be detected. The higher the sensitivity level of the camera, the smaller the object is needed to trigger motion.

Region or Mask: 

When it comes to avoiding any type of false motion events, using region on a DVR will do the trick. This is basically setting spots on a check marked frame that you want to have no detection at all. Imagine the camera is installed in your backyard and is looking at trees in the background. Your crucial breaking points where possible intruders could get in is in the foreground of the same area. Then when trees move it will cause a lot of motion events just because of the fact that there are changes in the pixels, therefore the DVR will recognize that as a motion event. One thing you can do is use region to mask the background area where the trees are and the camera will basically omit that region in the image. Also notice that if motion is triggered in the foreground area and it meets the threshold of the Anti-dither, then you will have a motion event with the trees in the background as well. In another words, region does not remove part of the video if motion is detected, instead is just an algorithm that tells the DVR to not detect anything within the region.

Below a video that demonstrate how to mask an area:

The biggest challenge of motion detection configuration is to find the settings that do not produce false alarms and at the same time do not miss any actual intrusions. The rule of thumb is: the sensitivity should be as high as possible while not producing false alarms and also adjusting the sensitivity according to the environment. The default sensitivity level of our Security Camera Kind DVRs is 3 (on a scale of 0-6) and it is a good setting for most standard cases.

How to use the Alarm Outputs on your Security DVR

Written By:
Monday, March 17th, 2014

The DVR is commonly used or mostly used as a recording device for Video surveillance, some DVRs have Audio Inputs (almost everyone now days), but your unit also may come with extra outputs to execute actions like turn lights on, unlatch doors, open the garage of your house, etc.

These outputs are located in the back of your DVR, and can be NO (Normally Open), or NC (Normally Closed). The NO output (Normally Open) means the initial state of the output position before activation, in this case there will be no continuity between connection points while the output is not activated; once the output is energized, there will be continuity between both connection points. Normally Closed output has the inverted effect, meaning there will be continuity between connection points while the output is inactive, and once the output is active it will be no continuity between the connection points. Keep in mind that these outputs are no power supplied, meaning they don’t supply power from the contacts, so you can use them as contacts to control external powered circuits; also, this contacts have certain tolerance, from 0.25 to 2 Amps, depending on the model of your DVR and the type of voltage you are using.

For example, if you want to unlatch a door at your office, you will need an external 12VDC Power Supply, a 12VDC Electrical Strike, and 18/2 AWG cable. You will have to mount the Electrical Strike at the door, run 18/2 AWG cable from the Electrical Strike to the location of your DVR, connect one wire of the 18/2 cable to one of the connection points on the NO output of your DVR, and the other wire to the negative side of the 12VDC Power Supply, and run 1 wire (preferable red) from the positive lead of the 12VDC Power Supply, to the other connection point of the NO output you are using from your DVR (see figure 1)

DVR Alarm Outputs

These outputs can be used for different applications like turning lights on or off in front or back yards, operate garage doors, temporarily deactivate or activate sensors like motion detectors or door switches. Best of all, these output can be program to interact with the cameras, for example you can activate an output every time the camera motion detection is activated, so if the camera detects movement, automatically will activate the output, and if you are trying to protect an area (for example, your backyard) you can connect a 12VDC relay to one of the outputs of your DVR, to energize a loud horn, so it will scary anything away, or if you may want to allow your pet to get into certain area of your house ( example given, the screen patio, or Florida room) you can have the output deactivate the motion sensor or the door contact of your alarm for this area, so it won’t activate the alarm.

Because of the low amperage resistance and the limited voltage capability of these outputs, they cannot be operated on circuits of more than 24VDC, and cannot be operated in AC voltage. The good news is that if you need to control an AC powered circuit with one of your DVR outputs, you can do it by using an External 12VDC or 24VDC Relay that can handle AC voltage on its contacts. The connection is a little bit more complex, but you still saving money by using the outputs on your DVR, instead of buying expensive controllers.

For instance, if you want to control the garage door at your house, the first thing you need to do is check the garage door controller manual to find out if the openers are 12VDC, 24VDC or 24VAC operated control circuits. If they are 12VDC or 24VDC operated circuits, you can used a 12VDC or 24VDC External Power Supply, and the same circuit show on figure 1, but you will replace the Electrical Strike for the points of connection for signal input at your garage door controller. If you garage door uses 24VAC for the control section of the garage door, you will need to get a 12VDC Relay that can handle AC voltage on its throttle, and a 24VAC Power Supply, to supply the voltage needed to control the garage door (see figure 2).

DVR Alarm Outputs

One of the most interesting applications I have seen using these outputs, is the utilization of one of these outputs to control the activation and deactivation of an AC system inside an office, where the AC unit will activate only if the camera see motion detection on the entrance of the building, and will give a deactivation signal after certain amount of time, by programming the temporizer in the thermostat of the unit, or if the DVR comes with the option, give certain amount of activation time to the output.

Some DVRs are also equipped with Alarm Inputs, which give you the option of adding devices to activate alerts and buzzers on the DVR, or you can redirect these inputs to activate an output, every time the device connected to the input of the DVR (example, motion detector) activate this input.

Just like the Domestic Burglar and Fire Alarms now days that come with Video and Audio Inputs, to connect cameras and microphones over the Alarm system, like Comcast Home Security Systems, the DVR gives you the option to connect no only Surveillance Cameras, but Motion Sensors, Door switches and contacts, microphones, and it gives you alerts every time one of these devices is activated.

Our DVRs come with these particular outputs, and one of the biggest advantage we have, is the ability to control these outputs over the network, so you can execute actions anywhere you have your computer or laptop, and an internet connection. It is also available in the Apps used on your smart-phone, so these outputs can be controlled anytime, and anywhere with a touch of the screen on your mobile device.

What is the Difference Between Analog, HD-CVI, and IP Security Cameras Systems?

Written By:
Tuesday, March 11th, 2014

What is the difference HDCVI, DVR, and IP NVR
Security camera systems come in many different forms and its best to know the difference between them all to help decide what system works best. Here at Security Camera King we sell three different types of technologies. They all have their advantages and disadvantages and just like everything else the more advantages you get with a system can come at a price. Starting at our lower end models is our Analogue cameras which have been the pioneer of security cameras and have served us well. Going to the top is our IP camera systems which produce high definition quality picture and is becoming a standard in the security camera world. Then right in the middle is our HD-CVI camera system which utilizes Analogs existing cable technology but delivers the same picture quality as our IP systems. Given the different options of security camera systems to choose from can give a little confusion but once broken down and dissected will turn confusion into knowledge and help make the right choice for a security system.

When security cameras became popular the first technology was called Analog. These systems worked by using coaxial cable to transmit signals from the camera to a recording device such as a VCR or more relevant a DVR. This technology has worked well for years and is still around today. The benefits of Analog are that its cheaper than most other systems, it is very reliable, and has many options of cameras and DVR’s. Analog is considerably cheaper then and IP or HD-SDI system and still gets the job done. To put in perspective, the difference in cost, if placed side by side a comparable 8ch Analog system and a 8ch HD-SDI system you will spend over 50% less on a Analog system. You won’t get the same picture quality but if you’re looking for a dependable video security system that will provide you a quality picture then this is the best option. The reliability of Analog systems is considerably higher than other systems because of the technology it uses and how it has been perfected for years. They increase in dependability if they are installed correctly and if quality cable was used during the install. The last benefit of Analog camera systems is that they have a wide verity of cameras and DVR combinations to help fit your budget. Cameras can have different technologies that can help with license plate capture or allow you to see at night with a technology called Infrared light and DVR’s can allow you to record at better resolution and faster frame rates. Analog is not the top choice but can give reliability and more options than most other systems out there.

IP stands for “Internet Protocol” which is the next camera system on the list and for most would be the best system for the money. IP camera systems work by using a standard Ethernet cable to connect several cameras together to your LAN “Local Area Network” in your house. What’s nice about IP cameras is that you don’t have to use a recording device on the other end to operate them, they all consist of their own web based program that can be accessed through your computer or a phone for viewing or local camera recording. IP cameras have the most sophisticated technology that gives them ability to achieve these types of operations. If the need to record your footage we sell NVR’s “Network Video Recorders” that allow you to connect up to 128 cameras to a single recorder. It also make it a central viewing station for all of the cameras you set up instead of logging into each individual camera. The cameras themselves can have different types of lenses which gives it the ability to view far away objects without distortion or view a wide shot for more coverage. The best thing about IP camera system is that you can record at a high resolution. In some cases you can record as high as 10 Megapixels! That’s 5x the size as your standard 1080p HD TV. With that picture you can digitally zoom into a video with little to no distortion. There are also other benefits to IP camera systems like POE “Power Over Ethernet” which allows you to use one cable (Ethernet cable) to send power and data to avoid the use of and additional power cable. Doing so can save you time and money for installations and repairs. IP camera systems are becoming more affordable every day and will eventually become the standard in security cameras.

Getting the best shot is what most people are looking for in a security camera system and this can be achieve using the same technology as out predecessor the Analog camera system. HD-CVI can give you the reliability and price of a Analog system but the picture quality of an IP camera system. There are also a lot more benefits to using a HD-CVI camera system for example you can transfer video, audio, and data all through the same coaxial cable. This is something that is possible through IP but new to Analog. This is a benefit because it will save you on wiring and time with configurations on each unit. It also makes it possible to control the OSD functions of the camera at the DVR source. This makes it easier to manage your fixed cameras as well as PTZ’s (Pan Tilt Zoom) The biggest advantage is you can record at 720p resolution ,normally found on a IP camera system, for over half the cost. It is a growing technology but shows its true potential in the field.

Knowing the products and technologies in the security camera industry can give you the upper hand in selling or for personal use. Analog gives you reliability and options all at a reasonable price. IP producing quality picture and on the move to becoming an industry standard. Last but not least HD-CVI which gives you most of the benefits of IP with a similar cost to Analog. Now that its broken down you can digest the information to make the best choice.

How to prevent your DVR from being stolen

Written By:
Tuesday, February 11th, 2014

In today’s world, you can’t be too careful. This article will show you how to hide your DVR in order to prevent anyone from stealing it. If your DVR is stolen, your surveillance system is pretty much useless unless you have some sort of backup. There are many different ways to conceal your DVR so that a burglar cannot do any damage to it or steal it in the case of a break in or vandalism. Usually criminals that know they’re being videotaped will try to either destroy the security cameras or destroy the device they’re being recorded on. Make sure you’re ready for it and one step ahead of them so that you can still have your evidence if any of this should occur.

DVR Lockboxes


DVR Lockbox One of the main solutions that most people inquire about is a DVR Lockbox. A lockbox can be any type of enclosure made for a Digital Video Recorder so that someone can’t simply take it and run off with it. It’s also useful for keeping people from being able to shut it off or access the main settings and can even keep people from deleting the footage on the recording device. You must make sure that very few trusted people have access to the keys of the DVR Lockbox so that if any changes need to be done to the device, its being done by someone you know won’t delete important evidence. Many DVRs these days can be accessed remotely so that no one actually has to touch the physical device and the trusted people or person will have a login for the DVR with restrictions on what settings they can access. The Lockbox is also great because it will protect the DVR from any vandalism. My suggestion would be to bolt it down to some beams in the wall to make it much more difficult for anyone to get to it or move it.

Hiding Your DVR


Some people decide that they are not going to spend the extra money to purchase a lockbox. That is not a problem so long as you have a really good spot to hide the DVR so that no one will find it. Some homes or businesses will have a secret location or compartment created by the owner where you can hide the DVR out of sight. A lot of times a burglar won’t have much time to search for a device and will want to get out of the location they are robbing as quickly as possible. Especially if you double up your surveillance system with an alarm. We have heard of many great ideas. Here is a list of a few places that may be a great hiding spot for your security camera recording device:

1. The Ceiling – this can be a drop ceiling, or even an attic. Just be aware of the temperatures because some hot temperatures have the ability of damaging the hard drive in the device.

Hide DVR in Attic

2. In Walls – I have seen some homes which have been modified with false walls, or even a locked safe inside of a wall that can be covered by a picture frame to hide where the device it hidden.

3. Hiding your Security DVR in a Closet – Hide the DVR in an uninteresting closet. Sometimes this can mean putting it up on a high shelf in a closet with some clothing or boxes in front of it. Just make sure the wires are hidden as well that are coming into the back of the DVR.

4. Hiding your DVR in a Basement or Cellar – If you have some sort of underground storage in your building, you can make an area in a basement or cellar that would be perfect for hiding a DVR. Especially if these areas are only used for storage, there will be a lot of stuff in front of the DVR that will hide it such as old boxes.

5. Cabinets – Some companies manufacture in-wall tilt-out steel cabinets.

False or Decoy DVR


One of the best solutions, in my opinion, for hiding the digital video recorder from your surveillance system is to have a decoy or false DVR available to the burglar. Many people are currently upgrading from older analog systems to newer digital IP systems. In turn, you’re left with a DVR that is no longer being used and the first thought that people have is to get rid of it by selling it or giving it away. If you have an extra DVR, set it up in a place that is not hidden, with some wires fully attached. This way if someone breaks into your location, they will take that DVR thinking that they are smart and have stolen all of the evidence when in reality, you have a hidden recording device tucked away in another room or location as mentioned above that no one else has access too. They will quickly leave the location and you’ll still have your evidence to show to the police.

Another solution is to look online and see if you’re able to find a DVR that is no longer functional for one reason or another. You may even be able to go on craigslist or eBay and find a DVR that is really old and no longer being used by someone who would love nothing more than to get rid of it at a really old price. Some devices are even being sold online “for parts”. This means that the DVR is no longer functional and they are only selling it for a user who has the same type of DVR but only needs it to farm out a part of the DVR that may still be of use. This would be a great solution because then you’ll have a cheap secondary recording device that will not be a great loss if stolen.

Lastly, you can have a secondary DVR set up that is actually recording all of the footage from the first DVR. This also works if you have an external drive that you can send all of the data to on a regular basis. This way if the DVR is stolen or damaged, you still have an external hard drive that is storing all of the recordings. The SecurityCameraKing.com DVR’s do actually have a feature that will allow you to back up the DVR footage through FTP and even externally to another USB hard drive attached to the system. The FTP feature is also a great solution because ultimately, if you had to, you could send back up of the footage to an external server that is stored in another location.
