The safety of private and commercial property is an urgent problem, especially for remote sites. Equally important for managers at various levels is the ability to remotely monitor the activities of subordinate personnel. An excellent solution to this problem is an autonomous video surveillance system that works in any conditions without being connected to industrial electricity. The choice of products is great, but only a limited list is suitable for specific conditions.
Main selection criteria
Standalone webcams are similar in appearance, but have a number of differences in technical capabilities, characteristics and installation location. You should pay attention not only to the price and configuration of the system components.
When purchasing stand-alone outdoor video cameras with a battery, the following criteria must be taken into account:
- body tightness;
- vandal-proof performance;
- resistance to temperature extremes;
- corrosion-resistant coating;
- high light sensitivity;
- night and day mode of operation;
- wide surveillance sector;
- sufficient resolution;
- battery working in the cold;
- infrared illumination duplicating artificial illumination.
The requirements for indoor cameras are much more loyal. The premises are maintained at a stable temperature and lighting, there is no risk of damage and theft of equipment.
Selection options:
- portability;
- noiselessness of work;
- anti-reflective lens coating;
- the ability to quickly replace the battery and memory card.
Night mode is needed for equipment that is installed to protect against thieves.
Principle of operation
A modern autonomous video surveillance camera can work without recharging for 10-15 days, provided that large-capacity batteries are installed. There are models that have an almost unlimited resource due to receiving power from solar panels. Such devices are installed in hard-to-reach places, where you can get to an autonomous outdoor video surveillance camera only with the help of special equipment.
The principle of operation of the devices is to collect, accumulate and transmit information. Its output can be performed continuously online or only when the motion sensor is triggered. The first option is used in security systems when the object is constantly monitored. Products of the second type are installed to detect the fact of violation of the perimeter or intrusion into the room, followed by detailing the event.
The image output is carried out by wire, via the Internet or local Wi-Fi. If continuous monitoring is not necessary, a standalone video camera collects information on a memory card. Then it is extracted, inserted into one of the computer devices, the recording is viewed and analyzed.
If necessary, a cyclic mode is introduced into the hardware program, when information is erased as the medium is full.
Varieties of autonomous cameras
When equipping a house, summer cottage or other real estate object with an autonomous security system using video cameras, you should purchase products from reliable and trusted dealers.
The following types of cameras are on sale that can work without electricity:
- Immobile. They are fixed in a static position and cover a certain area.
- With rotation function. View a wide sector, allow you to replace several conventional cameras.
- With recording on a memory card. Direct or archived recording is used, which makes it possible to store a large amount of information.
- With additional features. When the motion sensor is triggered, sirens, lights, lighting connected to one system are triggered.
- With real-time data transmission. It is carried out remotely via GSM, 3G networks through a standard SIM card inserted into the device's slot.
The type and complexity of the device is determined by the conditions of its operation and the specifics of the protected object.
Camera connection
The very process of mounting a stand-alone camera does not present any difficulty, even for an unprepared person.
- Checking the performance of the product. Testing of device parameters - power supply, storage, sensors, backlight, data transmission.
- Synchronization with the receiving device, if the data transfer will be carried out online.
- Mounting a bracket for attaching the product to a wall, pole or fence.
- Fixing the camera, turning it on, setting up, setting the desired parameters.
Covert surveillance, in accordance with the law, can only be organized within a private territory: premises in the house, courtyard, garden, vegetable garden. If public areas are within the sight of the lens, such areas are equipped with warning signs.
Advantages and Disadvantages of Standalone CCTV Cameras
The range of applications for stand-alone video cameras is practically unlimited. The equipment can be used not only for security purposes. With its help, observation of domestic animals, fishing and hunting equipment, shooting interesting episodes in the wild is carried out.
All this is possible thanks to the following advantages of video equipment:
- a wide range of models that differ in the set of functions, weight, size and appearance;
- small dimensions, allowing products to be placed in a confined space, where they do not attract attention;
- compliance with modern technologies of wireless data transmission with the possibility of simultaneous use of several communication channels;
- high resolution of optics and matrices, which allows you to see the smallest details of the footage;
- ease of installation, configuration and maintenance;
- availability of components and consumables;
- the ability to quickly move to a new location when the need arises;
- availability of day and night shooting modes with their automatic switching;
- work in conjunction with the equipment included in the "smart home" system;
- long term of work without recharging;
- a large amount of stored information.
The devices have a limited operating temperature range. Even the most modern battery is discharged sooner or later.
Devices are easy to break, damage, and easy to steal.
For each individual case, you need to select a model with certain characteristics and options.
