Digital Cameras

With countless CCTV camera systems on the market, it can be almost impossible to decide which solution is best for your commercial property. At Lock and Tech USA, we are proud to be one of leading commercial CCTV providers, and able to help you keep your business safe and Secure

Our team are regularly approached by people with a wide range of questions about how to keep their business safe. One of the most common questions is whether an analogue or digital surveillance system provides better coverage while still being a budget-friendly solution.

Analogue CCTV cameras record images to a digital recorder which converts the video to a digital format. To view the video, the DVR needs to be connected to a monitor or router to be broadcast through an internal network for remote access. However, there are government regulations for the strength of analogue signals.

Digital CCTV cameras or internet protocol cameras record in a digital format so a conversion process is not required. The digital data is sent to a dedicated network video recorder through the existing network and can be accessed remotely.

Benefits of digital CCTV camera systems

    IP cameras offer a much higher resolution than analogue cameras. Even the best analogue cameras cannot deliver the image quality of digital cameras. At Tecsec, our IP security cameras have a minimum of 1.3 megapixels. This is almost three times the average resolution of the best analogue cameras, making it easier to see details such as license plates and identify physical features of intruders.
    The hassle of wiring is minimised when it comes to using digital camera surveillance. IP cameras only need to be wired to a network switch or wireless network which will transfer the signals to the NVR. This way you can install more cameras without being limited by the number of ports available on your digital video recorder (DVR).
  • IP cameras powered through a Power Over Ethernet (PoE) capable network switch removes the need for a separate power source. Installation of digital CCTV systems can be much more straight forward for these reasons.
    Digital transmissions are not disrupted by other analogue wireless devices. The majority of digital CCTV systems have in-built encryption, ensuring unauthorised access to your video recordings is prevented. The data is also usually backed up on a redundant array of independent disks (RAID) system which provides back up hard drives in case one fails.
    Typically, digital cameras cover areas up to three times more than analogue cameras. They are also more likely to have a zoom function without becoming too grainy. This means the higher unit price of installing digital cameras may be balanced out by not needing as many cameras to cover your entire business.
    The remote access IP cameras gives people peace of mind while on holiday or working abroad. Not only is it possible to view the footage, but you can control the camera’s position from a remote location.
    Digital cameras provide more video analytics than analogue cameras, including the ability to flag unusual motion and send alerts to the owner. Its ability to read data also makes it possible to search for activity in a specific area on the image.
  • Analogue CCTV systems are widely considered an outdated form of security systems, with digital CCTV cameras becoming increasingly competitive on all fronts – including cost.

Analog Cameras

If you’re thinking about upgrading your analog cameras to IP, there are a variety of factors to think about. While the price gap between the two is getting smaller, there are advantages and disadvantages to both and what you choose ultimately depends on your organization’s specific needs.

Benefits of Analog Cameras

  • Cost: The most obvious reason to stick with your analog system is the price tag. Analog cameras tend to be significantly cheaper, especially as your camera count increases.
  • Larger pool of installers and vendors: Since analog cameras have been around for years and because they are fairly simple to install, you may have an easier time finding an installer, as well as a vendor, Lanni says.
  • Simplicity: Analog cameras are fairly easy to run, sending recordings to a digital video recorder (DVR), which then converts the analog to digital and stores it. DVRs are also simple to set up and run.
  • The technology is getting better: High definition (HD) analog has tremendously increased the picture quality and the resolution. You can get four and five megapixel cameras that are HD analog, and that’s impressive. However, when you compare apples for apples on your resolution, there are many more benefits to an IP camera.

Disadvantages of Analog Cameras

  • Frame rate and image quality: The frame rate of analog cameras is lower than that of IP, so they’re not ideal for areas that have a lot of motion or that need to be seen in high detail. Images are not as sharp and may appear grainy or blurry. You also can’t digitally zoom in like you can with IP cameras. However, for certain situations or areas, image quality may not be a crucial factor. Depending on the application, there are plenty of circumstances where a high frame rate isn’t necessary.
  • Less coverage: It may take more analog cameras to cover the same amount of area as it would take one IP camera.
  • More cables: You need a power cable, plus a DVR cable, whereas you only need one cable with IP cameras.
  • No encryption: A lack of encryption means a hacker could potentially access your information or replace your signal with an outside one.

Box Style Cameras

The original security camera, this design is still being used in security solutions today. Box cameras do not come with a lens. Instead you have the option to select from a wide variety of lenses. Another strength of the lens design is that they are larger than the typical camera. This means more light can come in contact with the sensor, and this gives you more clarity. Many people also like the impact a box camera can make when placed in a large outdoor housing.

Typically they scream “high security”. Lastly, you have incredible versatility for mounts. There are hundreds of solutions (housings, mounts, and brackets) that use standard bayonet mounts.

Box Camera Terminology

AWB – Most modern security cameras have built-in AWB. Video that is captured in fluorescent light will look a lot different that images captured using HID lighting. Sometimes colors become washed out, or look like a different color altogether. A security camera can overcome this problem and adjust the video utilizing AWB in its DSP. This technology analyzes the video in black and white to determine what is truly white and what is truly black. From that analysis, the true color of the objects in the video can be determined. The camera then makes adjustments to the video and sends it on to the DVR for recording or viewing. C/CS Lens – C Mount and CS Mount type lenses comprise a standard for video lenses that attach to a camera via a threaded collar. The difference between the two is determined by their flange back distance which is the distance between the back of the lens and the imaging sensor of the camera. CS Mount lenses have a flange back distance of 12.5mm vs. 17.526mm for C Mount lenses. All box security cameras offered on our site will accept C or CS Mount lenses. CCD – All surveillance cameras utilize an image sensor to convert light into electrical signals. There are basically two kinds of image sensors, CMOS and CCD. Most security cameras use a CCD or Charged Coupled Device. Neither type of image sensor is categorically superior to the other, as they both have their strength and weaknesses. A major benefit of CCD vs CMOS is that they typically perform better in photographic, scientific and industrial applications which require exacting imaging standards. These types of cameras are typically larger due to the CCDs inability to integrate any image processing circuitry onto the chip itself. A typical surveillance camera configuration consists of a CCD imaging chip, multiple supporting chips, and a lens. CMOS – As with CCD, it is common to find security cameras with CMOS or Complementary Metal Oxide Semiconductor image sensors. A major benefit of using CMOS vs CCD image sensors is that many of the image processing functions of the camera can be built into the CMOS chip itself. This allows for more compact circuitry and smaller camera size. In theory, a security camera could consist of a lens and one CMOS image sensor. This is due to the capability of including all image processing circuitry on the CMOS chip. However, in most applications, manufacturers that utilize CMOS also add other image processing components. Day/Night Camera – All day/night surveillance cameras are designed to provide the best possible images in daylight and low-light conditions. During the day, infrared light entering the camera can cause the images to be discolored or distorted. At night any extra light that the camera can gather, whether infrared or not can be used to improve LUX rating of the camera. That being said, the security camera must filter the infrared light out during the day, while allowing it into the camera at night or in low-light situations. Normal day/night surveillance cameras achieve this using software built into the camera. This is a somewhat “quick and dirty” method as the camera has to determine what wavelengths of infrared are undesireable. A True Day/Night camera uses a much more precise method of filtering out infrared light. A physical filter called an ICR Cut Filter that is tuned to a certain range of infrared light is positioned in front of the image sensor during the day. At night, it is mechanically moved out of the light path using a motor or actuator thus allowing the infrared light to enter the camera. This is the preferred method. DNR – In low light conditions or when viewing a scene that is illuminated using infrared, the main problem is noise. Light can scatter and infrared from the camera can illuminate dust and other particles in the air. This is particularly problematic when using the camera to detect motion. All the excess “movement” caused by noise triggers false motion events and eats up hard disk space. A feature of some of the more advanced surveillance cameras is DNR or Digital Noise Reduction. The security camera uses a DSP or Digital Signal Processor along with an algorithm to detect the noise in the video and digitally remove it. This smooths out the video and make motion detection more accurate. DSP – After the image sensor in the camera collects the image and converts it to an electrical signal, the DSP or Digital Signal Processor takes over. The DSP not only converts the electrical signal to a digital image, but it also performs any image manipulation that the camera is designed to perform. For example, the DSP would perform any AWB functions or WDR functions. Field of View – The Field of View or FOV of a camera lens is measured in degrees. As the focal length of a lens is increased, the field of view decreases and vice versa. It is important when choosing a lens for your security cameras that you keep in mind that when a “zoom” lens is used, that the field of view will be very narrow. In contrast, when you want a wide angle lens in order to capture as much of an angle as possible, the focal length will be very short. The chart below demonstrates some FOV angles associated with some common focal lengths.

Dome Cameras

Indoor Dome Security Cameras

There are certain instances where a camera is required to be lightweight or weather resistance is not a factor. In these cases, an indoor dome can be exactly what you need. In this section you will find light vandal domes and cameras specifically designed for use indoors only.

Vandal Proof Dome Security Cameras

One of the problems with adding security to your home or business is that the cameras themselves can become the target of tampering and vandalism. These cameras are designed to resist impact from vandals as well as make it more difficult for anyone to make an unwanted adjustment to the camera view.

All of these options are exceptional values and very suitable for your home or business installation.

Pan Tilt Zoom Security Cameras

In some cases, regular cameras simply will not give you the full amount of coverage. You may need the versatility of a camera that can be adjusted quickly, remote change of direction or zoom, or maybe its the ability to lock on and follow a moving object that shouldn’t be in an area.

In each case, there is only one choice: PTZ, or Pan/Tilt/Zoom. These cameras have the ability to spin and angle up and down with their motorized interior mount, as well as zoom in and out and auto-focus with their motorized variable focus lens.

Total control is the ticket when you install a PTZ camera.

Modern pan tilt and zoom CCTV

Pan Tilt Cameras, also called PTZ cameras, are capable of being controlled remotely. In their most basic configuration the camera can be made to move left/right (Pan) and up/down (Tilt). More advanced models can also zoom in and out (Zoom). Most DVRs are capable of accepting inputs from a PTZ camera and allowing control of the camera from the DVR or remotely via the DVR’s client software.

Bullet Style Security Cameras

Also known as “cylinder cameras”, bullet cameras have many advantages. They are usually very easy to mount and adjust. They have the most weather resistant design. They give a little space off from their mounting surface. They’re an excellent option for a novice. When you need versatility in your installation, bullet cameras often provide exactly that.

Bullet cameras are generally weatherproof, self-contained cameras. Many bullet cameras come with built-in IR LEDs. Bullet cameras are good for use when there is a low risk of vandalism as the cameras can be repositioned fairly easily.

License Plate Security Cameras

One of the most popular applications for cameras today is to attempt the recording of license plates. This is clearly one of the most difficult applications for todays camera technology. Glare from lights, high speeds, angles of approach, lighting variables, camera position, distance and many many more factors come into play in your design. These cameras give you an excellent chance at capturing plate information when installed within the proper parameters.

When designing your plate capture scenario, we do highly recommend you either consult our system or our various databases to make certain you’ve got the optimal design.

License plate recognition security camera

If you want to capture license plate numbers for identification purposes, then you will need specialized security cameras to accomplish this consistently in various environments. Trying to use a conventional security camera for this purpose will yield inconsistent results. There are many factors that will make reliable license plate capture very difficult without the right set up, configuration and products. Headlights, brake lights, IR reflection, darkness and sunlight can all limit your ability to capture license plates. Following is how to correctly and reliably set up license plate capture. – Use two cameras When designing your license plate capture set up, you should use two cameras to accomplish the task. One camera will be used as an overview camera. This can be a standard box or bullet CCTV security camera that can see in low light environments. Preferably this camera will not have infrared LEDs so that it does not interfere with the other camera that will be dedicated to license plate capture. The second camera will be your dedicated license plate camera. Our license plate cameras have the features you need to accomplish this task. While the overview camera can use a wide field of view to capture details like the type, color and make of the car, the dedicated license plate camera will be zoomed in tight so that the only image in view is the license plate. – Correctly position the cameras The overview security camera can be positioned on a pole or building mounted high enough to provide the overview you need. However, the dedicated license plate camera should be mounted as close as possible to the location of the vehicle. Ideally, it will be mounted only a few feet of the ground and only a few feet away from the target vehicle. The perfect distance would be within 10 feet of the vehicle license plate capture location. Do your best to avoid any extreme angles as this will make the capture more difficult. While it is possible to capture plates reliably from longer distances, the further distance the camera location is, the more possibility for complications. – Control the traffic In the best case scenario, the subject vehicle will come to a complete stop or near complete stop for license plate capture. The typicel scenario is the entrance to a community or development. If there is no gate, consider using speed bumps to slow the traffic down as much as possible. Also, there should be a separate license plate capture camera for each lane of traffic. If you try to use only one camera to capture multiple lanes of traffic, the camaera’s field of view will be too wide and you will need to digitally zoom in to the recorded footage in order to identify the license plate. This is not recommended since digital zoom will result in pixelation and deterirorated quality. – Configure the camera Take advantage of the great features in the license plate camera. Using head light supresions or eclipse funtions will allow you to suppress the effect of headlights and brakelights. Also, if zone masking is available, you can mask out potential trouble areas. Shutter speeds should be set high so you will need to make sure the area is well lit or use infrared illuminators to allow the camera to capture successfully. Every environment is different so you may need to fine tune the settings, lens apperture and camera positioning until you get it to work right. While reliable license plate capture can be tricky, if you use the cameras we recommend, you will succeed. – Using Megapixel Cameras Typically we recommend standard CCTV cameras for license plate capture. CCTV cameras use CCD sensors that perform better in low light scenarios. Megapixel cameras have much higher resolutions, but they typically use CMOS sensors which do not perform as well at night. Unless the area is extremely well lit, we do not recommend the use of megapixel ip cameras for this application. If however, the area is very well lit, then using megapixel cameras will allow you to capture license plates from longer distances and wider field of views. Using a 2 or 3 megapixel camera in a well lit area may even allow you to use a single camera for overview and capture and possibly could be used to cover multiple lanes of traffic.
