Design, installation and maintenance of security camera systems (CCTV)
Prompt designs, builds and maintains professional surveillance systems of up to hundreds of cameras. Our solutions are not only cost-effective, but also tailored to the individual needs of your company.
Wireless and wired camera systems
All camera systems can be wireless, but we prefer cabling because this way the system will work faster, more stably and reliably.
DVR and PC (server) -based Observation Systems
Target capture systems are recommended for a small number of cameras (smaller offices and private homes). You can connect a monitor to them—if you need a monitor at all: most people check them from their phone.
We recommend PC or server-based systems for a larger number of cameras (for industrial areas, office buildings). These are much more customizable in their operation—for example, they are capable of the following:
- multi-level user management,
- sharing of authority for users,
- creation of different camera views for each user,
- use of map module (where you can upload a map in JPG or other image format, place the cameras on it, on the icon on which you can click to open the camera image immediately),
- for multi-monitor view.
Indoor and outdoor cameras
The differentiation of indoor and outdoor cameras is fading away. The only difference between the two is the design: while outdoor cameras are vandal-proof, indoor cameras are not, their cover is made out of plastic, and they aren't UV-resistant.
We usually use outdoor cameras everywhere, because they are just as decorative and technically just as suitable, but more durable, more rugged.
IP camera or analog?
The analog or IP differentiation only determines the signal transmission between the camera and the recorder. The two most important aspects when making a decision are how much money we want to spend on our camera system, and the required recording quality.
Although traditional analog solutions are the cheapest, we do not recommend them due to their extremely low resolution and the quality of the images they transmit. New, more advanced versions of analog are AHD, turbo HD and TVI systems, whose signal transmission is also analog, but they have a much higher resolution, giving a more detailed picture.
Analog cameras are cheaper and there is no delay in the displayed image, but the signal is often disturbed, for example by high voltage cables, radio waves—there is no such problem with fully computer-based IP camera systems.
PC-based IP cameras with digital signal transmission are more expensive than their analog counterparts and transmit images with a delay of one or two seconds, yet they are the most recommended, as they have many advantages:
- suitable for wireless (WiFi) connection so they can be used on their own, without cables
- we can use memory cards to record pictures
- because each camera has its own IP address, we can check camera images from the Internet from any mobile device or computer
- numerous, previously very expensive solutions can be done with it for example: you can remotely switch something on and off (e.g. lighting, opening doors), devices which give outer alarm signals can be integrated into the system
- we can fully parametrize them via the network.
- the whole IP camera system can be managed from one place
Our own camera system was installed in 2002 and has been operating continuously since then without any changes. In the online live image, the extreme, smaller camera images are updated every 5 seconds, and the large camera image in the middle is updated every 2 seconds. From the small camera images, you can choose which one you want to view in the middle, in large size.
Parts of IP camera systems
- IP camera,
- computer or server on which the recording software runs (for this we connect cameras based on their unique IP address);
- switches (network devices, which provide the network traffic between the cameras, recorders and displays; in most cases cameras get the power supply from the switches),
- router (which connects the internal IP video network with the internet),
- screen (display device).
We recommend the WiFi solution only if you need a camera at a place where the conditions are not in place to build a more stable and reliable wired solution.
Almost all cameras can provide a useful image during the night thanks to infrared lighting.
Classic infrared-LED cameras that illuminate the area in a patch can now be said to be obsolete. MOre modern ExIR LED cameras illuminate the entire viewing angle with a fraction of the LED number (while thr old cameras had 36 LEDs, the current ones have 2).
Classic infrared-LED cameras are slightly cheaper, but we recommend ExIR LED cameras, especially if receiving the best possible night camera image is important.
Speed-dome cameras can be rotated and controlled remotely. They rotate completely horizontally, and can move in a 90 degree angle vertically. (PTZ – pan/tilt/zoom). Their optics have a zoom range of up to thirty times and are capable of very fast movements. They also can be programmed to scan a specified route automatically, or to turn the camera when an alarm is received from the monitored area.
They can be controlled with a keypad with a joystick, or with a mouse via a recorder or server.
Because they are rotatable, the speed dome can trigger multiple fix cameras.
If a hidden camera is required, in most cases an IP camera -usually with pinhole optics- is suitable for the purpose in which an SD card can be inserted. This way you do not need a separate recorder but you can even connect to a computer network so it can be monitored via Internet.
Cameras with solar cell
Solar cell cameras are completely independent cameras, which are recommended for places without infrastructure (power cord, internet) (for example construction sites, illegal landfills). Their camera image can be checked via mobile Internet connection. They have batteries that they run on at night.
Camera system with alarm
Some camera systems—for example Myrasis 9—can be taught with a learning method based on artifical intelligence and mechanic learning to send an alarm only when a person is detected.
Some IP cameras have an I/O port on which a motion sensor can be mounted, so if the alarm goes off, it can send a camera image too. It is also possible that if the camera sees movement, a notification is sent to your mobile phone, but this can generate many false alarms (for example, if just a shadow moves on the camera image).
Intelligent camera systems, video-analytics
What triggered the alarm? Did a person or car move in the observed area? With its solution based on artificial intelligence and machine learning, our intelligent camera systems have learned to differentiate between them and can be taught to recognize any other object. Was there movement in the garden? The Prompt ML solution only sends an alarm when it detects a person! This is illustrated in the video below.
Some camera systems—e.g. Myrasis 9—not only can capture motion, but can also be configured to record when a particular face is detected e.g. based on an employee photo database. They can also be configured to capture images when there is movement beyond a certain area, or beyond a specific line.
Functions of observation cameras
We can set up camera systems for various purposes, for example:
- for security and property protection purposes,
- for space surveillance, both indoors and outdoors,
- for traffic counting,
- for license plate recognition to automate gate opening,
- to check and retrieve exits and entries,
- cash register supervision, etc.
