If you are the owner of a private house, you must have repeatedly thought about how to protect it from intruders. Is not it? One of the most affordable ways is to install video surveillance in the territory.
You can entrust everything to a security organization, but this is a more expensive option. It is much cheaper to install video surveillance for a private house with your own hands. We will tell you how to properly design such a system and help you choose the right cameras. In the article you will find step-by-step installation instructions.
To personally organize video surveillance on the site is not an easy task, but quite real. Of course, you will have to tinker a bit, but for the sake of maintaining material values and the safety of households, it is worth doing.
Stage # 1 - determine the number of observation zones
In order to determine the number of observation zones, it is worth knowing what this concept implies. In this case, the observation zone means a part of the territory falling under the camera's view.
In addition, the zone can be controlled by one or several cameras, and this issue needs to be decided before the start of installation work. If there is a desire to “see everything”, then it is worth noting that this will be a rather expensive option, in many cases completely unreasonable.
When placing video cameras, care must be taken to ensure that their angle of inclination provides the maximum view of the protected area. If the task is to protect the perimeter of the site, then cameras are best placed at the corners of the building
Mandatory places for installing cameras are:
- entrance to the house;
- entrance to the garage;
- wicket and central gate;
- places where it is easiest to enter the site;
- places where the equipment is stored;
- entrances to all buildings available on the site.
To make it easier to navigate, you can use the site plan. So it will be much clearer which zones should be covered by video surveillance.
Stage # 2 - choose the places to install cameras
By equipping a video surveillance system, owners of private houses can restrict themselves to installing cameras only on the site, but provided that they cover all places of possible penetration.
The number of devices is calculated solely from their own needs. If you need to monitor the perimeter, then just install the camera in the corners of the house. And for a general overview of the site, a camera on one of the posts will be enough.
An approximate layout of cameras in a private household. This arrangement is advisable to apply if you need to "see everything." In other cases, fewer cameras should be used.
To control the perimeter of the site, as a rule, cameras with a small viewing angle are used. They need to be installed on special supports or poles available on the site. It is also important to consider the presence of objects that can overlap the camera’s field of view (buildings, trees, poles).
To monitor the inputs, front-facing cameras with good resolution are most often installed. For example, for the front door you can install a peephole camera, and when entering the site - video surveillance is carried out using a video intercom.
In addition, cameras must be placed on the site in such a way as to avoid intentional damage to the device. Also, equipment should be well protected from adverse environmental influences.
Install CCTV cameras in places that are invisible to potential attackers. In addition, it is worth taking care of their protection from environmental influences, and in some cases, even provide anti-vandal protection
Be sure to include the night function for the selected model. So, contrary to popular belief, the infrared backlight of a device often cannot provide enough lighting for shooting.
The main components of a video surveillance system are cameras. Their selection should be given special attention. Costly systems are generally more complex to install. And cheap, outdated models will produce a blurry image.
To monitor the perimeter of a private home ownership, the number of cameras can vary from 8 to 16 pieces. There are two main types of cameras - IP and analog, below we will talk about them in more detail.
Below are some options for the location of surveillance cameras:

Video surveillance on the site
Broadcast from a digital camera
The camera located in the door peephole
AHD camera indoors
Option number 1 - analog camera
It is a device that can be connected to a computer or TV and see the image. Processing information from such cameras and recording it on a medium requires preliminary conversion to digital form.
For this purpose, a recorder is used, so in practice it does not make sense to use an analog camera without a recorder. Previously, it was believed that analog devices broadcast extremely low-quality images.
Indeed, the previously released PAL standard (720 × 576) corresponded to 0.4 megapixels - certainly not enough to get a high-quality picture.
In appearance, analog AHD cameras are difficult to distinguish from digital models. And the quality of the footage they are almost identical. The only difference is the price.
Now there are devices with a resolution of up to 2 megapixels, transmitting a color image. To transmit a signal in analog cameras, a coaxial cable is used. When installing modern AHD equipment, it is worth remembering that the cable length should not exceed 500 meters - compliance with this condition will help to avoid loss of image quality.
The price range of analog CCTV systems is much lower than that of IP systems. Another plus is the ease of installation and configuration of equipment. Among the shortcomings, we note the not too impressive functionality of the devices and their incompatibility with old equipment.
Option number 2 - IP camera
Digital IP cameras are self-contained devices. And to record what is happening on the media, some models can do even without a recorder. Digital devices have several advantages that distinguish them from analog models.
We list the most significant of them:
- High resolution broadcast picture (up to 8 megapixels) and scalability.
- Information is recorded through the cloud service.. To configure the system, you only need to download and install the program.
- Wireless connectivity equipment allows you to view the image from anywhere in the world.
Of course, IP devices are not without drawbacks, the main of which is their cost. Another significant minus is the incompatibility of cameras and DVRs from different manufacturers.
To ensure high-quality recording of footage shot at night, it is worth taking care of additional illumination. In practice, the built-in light bulb is often not enough
Which option to stop is the choice of the consumer. With a large length of cable lines, analog models should be preferred, and if you want to install a pair of cameras at a short distance from the DVR, it is better to choose IP devices.
The main stages of system installation
After the cameras have been selected, their number and places for installation are determined, you can proceed to the independent installation of the video surveillance system.
To do this, you will need:
- cameras
- DVR
- Power Supply;
- KVK cables and connectors;
- router
- USB modem.
Next, we will briefly talk about what stages the installation process consists of, and what needs to be done during the work.
Stage # 1 - laying cable routes
To unite all the components of the system, it is necessary to correctly position the tracks in the device of which the cable for the Internet is used. Coaxial cable is used to lay tracks for analog systems. It does not require the use of additional video adapters, and its shielded coating will protect the system from unwanted interference.
In IP video surveillance systems, twisted pair cable is used to lay cable routes. It is a cable with several pairs of conductors intertwined. Due to this interweaving, the influence of electromagnetic interference is significantly reduced.
As a rule, the laying of the line starts from the farthest points from the DVR, only after that they start connecting nearby objects. But regardless of the location, the cable length must be calculated with a small margin.
If you need to hide the surveillance cable from prying eyes, you can lay it underground. And for extra protection, it can be laid in ordinary metal or PVC pipes
To monitor the perimeter of a private house, it is planned to lay cable lines on the street.
To this end, two methods can be used:
- Open. When laying along the fencing of the object of observation or using additional supports. In this case, it is worth taking care of protecting the lines from adverse conditions. So, it is not necessary to neglect the insulation, and use the "air" lines more than 50 m long.
- Hidden. In this case, the cable is laid underground or inside the walls. For this purpose, special corrugated tubes can be used. But, from the point of view of profitability, it is much more profitable to use ordinary metal-plastic water pipes.
Observing the safety rules, it is worth noting that the lines of video surveillance systems should not be located closer than 40 cm to the power cables. This will help prevent broadcasting from cameras from interference.
If this distance cannot be maintained, they must be placed in a dielectric cable channel or a grounded metal sleeve.
Stage # 2 - mount cameras
When installing cameras, it should be borne in mind that they should not only provide an overview of the protected area, but also be invisible to attackers. In addition, monitoring devices must be installed in such a way that, in the event of a breakdown, they can be easily reached.
To connect analog models, you need a coaxial cable with a tulip connector:
- red wire - to connect power;
- white and yellow wires - to receive a signal.
Digital video cameras are connected using a twisted pair cable, two RG-45 connectors and a power cable.
To protect outdoor video cameras from adverse environmental conditions, the so-called "casings" are used. They allow even in bad weather to provide decent picture quality and extend the life of the device
As practice shows, for mounting video cameras on the street, you should not use the fasteners that come with the cameras - often, they turn out to be completely unsuitable for this purpose.
It is best to separately select reliable fasteners - this will avoid camera vibration or its fall, for example, from strong winds. For security reasons, experts recommend that you do not install video cameras on metal holders. In the event of a thunderstorm, the device may turn into a kind of lightning rod.
Stage # 3 - set the DVR and connect the system
Despite the fact that the DVR is one of the main components of the surveillance system, connecting it to the camera system is not difficult. The most important thing is to correctly connect the devices to the connectors intended for them.
It’s better to overpay a bit and purchase DVRs with the PoE function - it provides power to the cameras. In the case of using other devices, you will have to lay a separate cable to power the surveillance cameras.
Starting to launch a video surveillance system in a private house, you must carefully double-check the correct connection of all the devices included in it
For the correct and uninterrupted operation of the recorder, it is worth placing it in places with good air circulation. The device must not be allowed to overheat. Having connected all the components, you can begin to supply power to the devices. The registrar is connected first, and only then the cameras.
If the PoE function is not in the recorder, be sure to observe the polarity - plus is connected to plus and minus to minus. All connectors and joints must be protected from the influence of the external environment so that their oxidation does not occur. For this purpose, you can use special junction boxes.
Stage # 4 - do the hardware setup
The final stage of installation and connection of a video surveillance system for a private house is the setup of equipment. We can talk about fine-tuning the equipment for a very long time, here we will focus only on what stages it consists of.
Having connected and configured the equipment, it is necessary to check the operation of the cameras at night. If the screen is cloudy, you need to wipe the lens of the device, it may have gotten dirty during installation
So, the standard equipment configuration scheme includes the following:
- Setting the time and date on each of the devices. To do this, in the system settings you need to select the date and time for each camera. To exclude the display of the wrong time, it is necessary that the time zone on the router matches the settings of network devices.
- Formatting drives for storing information. Formatting of hard drives for video surveillance systems can be performed using the web interface, using the recorder itself, using the IVMS program.
- Configure cameras. Setting up recording devices consists in adjusting the angle of inclination and rotation so as to maximize the coverage of the viewing area.
- Video recording setup. As a rule, video recording settings are performed in the DVR client application. This program allows you to manage a large number of cameras from one PC, and everyone can easily figure out its interface.
- Configure remote access to cameras. It can be carried out using cloud-based video surveillance services or by entering the IP address in the search bar of the browser.
Having completed all these settings, we can assume that you have successfully coped with arranging video surveillance.
When connecting a video surveillance system for your home for the first time, it is usually very difficult to avoid mistakes. But worth a try.
Below we describe the most common mistakes made by owners of private houses:
- Incorrect calculations. This is the most common mistake made by almost everyone who faces the installation of video surveillance for the first time. In order to avoid it, you need to correctly measure the distance from the cameras to the recorder, and based on this, select the type of cable. Only correct calculations guarantee a high-quality image and high data transfer speed.
- Power shortage. The choice of power source has a significant impact on the smooth operation of recording devices. This especially affects their work at night. And if a DVR without the PoE function is included in the system, you should pay special attention to the power of the cameras.
- Information Storage Method. Everything is simple here, the more and longer you want to store information, the larger the hard drive will be needed. Modern devices have a large volume. For example, disks with a capacity of 3000 GB can store video footage shot in 10-45 days.
All these factors are important in the independent arrangement of a video surveillance system.
Another common mistake is incorrect wiring. With the independent organization of external monitoring, it is worth remembering that it is advisable to avoid excesses of the coaxial cable, it is fraught with a wire break
Wrong choice of system components and erroneous calculation of their quantity cannot guarantee the high quality of the work done.
