Surveillance is the monitoring of the behavior, activities, or other changing information, usually of people for the purpose of influencing, managing, directing, or protecting them.
Surveillance systems have been around for many years and in the infancy of the technology; these systems were primarily used by the government and a few businesses. Due to the advancement of surveillance systems and the increased crime rate, the demand for surveillance systems has increased tremendously. A surveillance system can give you additional eyes at all angles 24/7.
There are different types of video cameras that include options such as the following:
Resolution – The Resolution determines the video quality.
Pan/Tilt/Zoom – This function allows the camera to be controlled remotely allowing you to rotate the camera in any direction and gives you the ability to zoom in on any object.
Fixed – Camera can only be set to look at one area
Varifocal Lens – This means that the lens has the capability to be manually set to zoom in or out on a particular area and focused manually
Analog Cameras – Typically utilize an analog sensor called a charged couple device(CCD). Unlike IP cameras, analog have no built-in web servers or encoders and require no technical maintenance. These functions are implemented in the recording and/or control equipment.
IP Cameras – Typically utilize either an analog sensor such as a charged couple device(CCD) or a complementary metal oxide semiconductor chip(CMOS). The analog image sensor is then converted to digital by an analog-to-digital converter. The video information can then be transmitted digitally over and Ethernet connection to a computer or similar device. They are available in the same styles as traditional surveillance cameras such as Pan/Tilt/Zoom, domes, bullets, box, infrared, covert, and wireless. These cameras record can capture high definition megapixel images. IP cameras are typically equipped with and embedded web server and can be accessed and controlled over any IP network such as a WAN, LAN, Intranet, or internet. By utilizing a standard web browser or client software, users can view an IP camera’s video output from any remote location.
There are different types of video recording devices that include options such as the following:
Digital Video Recorder (DVR) – An analog and/or IP based recorder is a consumer electronic device or application software that records video in a digital format to a disk drive, USB flash drive, SD memory card or other local networked mass storage device. A DVR configured for physical security applications record video signals from close-circuit television (CCTV) cameras for detection and documentation purposes. Many are designed to record audio as well, whether at the camera or as a separate apparatus in an isolated area. Any good DVR CCTV system provides a plethora of advanced functions over VCR technology including video searches by event, time, date, and camera. There is also much more control over quality and frame rate allowing disk space usage to be optimized and the DVR can also be set to overwrite the oldest security footage once maximum disk space is achieved. Some DVR surveillance systems have remote capability that can allow access to live or recorded video using a Smartphone, PC, or Tablet.
Hardware features vary across different manufacturers and products.
- Connections to external control devices such as a mouse, keyboards, POS device, or PTZ controller
- Controlled outputs to external video display monitors
- Front panel switches and indicators that allow the various features of the machine to be controlled
- Network Connections
- Internal optical drives or HDD’s for archiving video
- Alarm event inputs from external security detection devices, usually one per video input
- Alarm event outputs from internal detection features such as loss of video or motion detection
- Multiple video inputs typically ranging from 4, 8, 16, and 32. Looping video outputs for each input which duplicates the corresponding input video signal
Software features vary across different manufactures and products.
- Log filing of IP addresses, USERs, Input, time and date stamping
- Alarm and event search
- Alarm and event logging on appropriate video inputs
- Sound recording channels
- User selectable image capture rates
- Selectable image resolution
- Compression methods determining the quality of playback
- Motion Detection, this feature detects motion in the total image or a user definable portion of the image.
- Lack of Detection, this feature detects the movement of an object into the field of view and remaining still for a user definable time. Detection causes an internal event that may be output to external equipment
- Motion detection provided on an input by input basis, this feature detects motion in the total image or a user definable portion of the image and usually provides sensitivity settings. Detection causes an internal event that may be output to external equipment and/or be used to trigger changes in other internal features.
- Lack of motion detection. Provided on an input by input basis, this feature detects the movement of an object into the field of view and remaining still for a user definable time. Detection causes an internal event that may be output to external equipment and/or used to trigger changes in other internal features.
- Direction of motion detection, this feature detects the direction of motion in the image that has been determined by the user as an unacceptable occurrence. Detection causes an internal event. Detection causes an internal event that may be output to external equipment and used to trigger changes in other internal features. Such as a stationary camera being used as a trigger to send a signal to a PTZ camera to look and focus in area of interest based of a preset you create.
NVR – Unlike the DVR, the NVR is not limited to be in the same area as your cameras cabling to one section. The unit can be placed virtually anywhere, it simply just needs to be on the same LAN network as the IP based cameras. In terms, a network video recorder is distinct from digital video recorders as their input is assigned on a network rather than a direct connection to a video capture card. Video on a DVR is encoded and processed at the DVR, while video on an NVR is encoded and processed at the camera, then streamed to the NVR for storage or remote viewing. An NVR is a software program that records video in a digital format to a disk drive, USB flash drive, SD memory card or other mass storage device. An NVR contains no dedicated video capture. However, the software is typically run on a dedicated device, usually an embedded operating system.
1. Determine requirements and need
– In this phase we work with the basic customer’s goals and needs. We focus on why does our customer need a security system? Most businesses would want to protect their assets and belongings.
2. Study location and Site Survey
– Analysis of the location that requires a surveillance system installed. We first determine the need, we usually ask the customer what do you want to view? What do you want to protect
3. Study the area and environment to determine the location and type of each camera used based on zooming requirements, clarity requirements, range, budget and sensitivity.
4. Next, we propose all types of cameras based on steps 1, 2, and 3. For example we might propose a weatherproof camera that runs day and night with motion detection and zooming or tracking
5. Lastly, based on the needs and requirements we determine the location of:
- The DVR System
- The Monitor
- The cameras
- The brackets and cables
- 24/7 Viewing
- Remote viewing via smartphone, tablet or PC
- Recording of video that can be reviewed at any time
- Crime Deterrent
- Employee theft Deterrent
- Improve Employee Productivity
