🧰 FAQ – Knowledge Center & Frequently Asked Questions

🎥 Closed-Circuit Television (CCTV) & Surveillance

What home surveillance system should I choose?

The choice of home surveillance depends on the finishing stage of the building. For unfinished buildings (raw state) or before renovation, digital IP surveillance powered via twisted-pair cable (PoE) is optimal. It ensures maximum stability, highest image quality (4K Ultra HD), and resistance to interference. In finished buildings where running cables is not possible, wireless Wi-Fi systems with local power supply work great.

IP or analog home surveillance – which is better?

We strongly recommend IP surveillance. It offers higher resolution, intelligent AI image analytics (human/vehicle recognition), and easy expansion via PoE switches. Analog surveillance (HD-CVI/AHD/TVI) is a good and economical solution mainly when you are upgrading an old system and want to reuse existing coaxial cables.

How to design outdoor surveillance for a single-family home?

Effective outdoor surveillance should cover all entry points (doors, garage gate, wicket) and the property perimeter. Selecting cameras with the correct viewing angle (2.8mm lenses for a wide frame) and IP66/IP67 weather-resistant housings is crucial. It is important to mount cameras at a height that prevents easy tampering (approx. 3-4 meters).

Construction site cameras – wireless Wi-Fi or GSM 4G/LTE?

A permanent Wi-Fi network is rarely available on a construction site, which is why external 4G/LTE GSM SIM card cameras are the best solution. They allow full remote viewing in locations lacking network infrastructure. It is worth choosing battery-powered models or those supported by a solar panel, making construction site monitoring 100% autonomous.

What surveillance works best for a company or large warehouse?

Scalable IP systems based on professional network video recorders (NVR) supporting from 16 up to 128 cameras are dedicated to companies and warehouses. Crucial elements here are motorized zoom (motozoom) cameras for face and license plate identification (LPR), integration with access control systems, and advanced disk arrays ensuring secure data recording for the legally required period.

What cameras should be chosen for a livestock barn or farm?

The specifics of livestock facilities (high ammonia concentration, moisture, dust) require cameras with increased chemical and mechanical resistance (min. IP67 ingress protection, IK10 vandalism resistance). PTZ (pan-tilt-zoom) cameras with strong optical zoom are recommended for barns, allowing farmers to remotely monitor animals (e.g., during calving) from a phone without entering the building.

How does intelligent AI image analytics work in Dahua and Hikvision systems?

Modern IP cameras from Hikvision (AcuSense technology) and Dahua (WizSense/WizMind technology) have built-in deep-learning artificial intelligence algorithms. They filter out false alarms by precisely distinguishing human and vehicle silhouettes from moving leaves, rain, or small animals. They also enable setting up virtual tripwires and restricted zones whose violation immediately triggers a push notification.

Why is it worth buying a ready-made 4-camera PoE surveillance kit?

A 4-camera PoE kit is the ideal price-to-capabilities balance for a standard single-family home. PoE (Power over Ethernet) technology allows transmitting video signal and power over a single cable (UTP twisted pair). By purchasing a ready kit at MikaShop.pl, you receive perfectly matched components: cameras, NVR recorder, industrial-class HDD drive, and a set of accessories ensuring a quick startup.

How to achieve good nighttime surveillance (24/7 color image)?

To enjoy a clear, colorful image in total darkness, choose cameras equipped with advanced high-sensitivity sensors and bright lenses (F1.0). Technologies like Hikvision ColorVu or Dahua Full-Color do not use traditional black-and-white infrared (IR), but instead illuminate the scene with visible, warm LED light, allowing full identification of clothing colors or vehicles at night.

When are outdoor PTZ Wi-Fi cameras useful?

Outdoor PTZ cameras with a Wi-Fi module are an excellent solution for patrolling large, open spaces (e.g., yards, gardens, parking lots) without installing multiple fixed-position cameras. Equipped with an auto-tracking function, they follow the detected object, recording its every step.

🔒 Intrusion and Hold-up Alarm Systems (SSWiN)

What home alarm system should I choose?

A good alarm system should be based on certified devices (Grade 2 or Grade 3). The core of the system is the alarm control panel, keypad, external siren, and properly distributed detectors. Brand selection depends on expectations: for advanced systems with building automation elements, we recommend the Polish brand Satel (Integra/Perfecta series), while for those looking for modern design and simple wireless operation – the Ajax system.

Wireless home alarm – what to buy to make it secure?

When choosing a wireless alarm, avoid cheap, unbranded devices operating on open frequencies. Professional wireless systems (e.g., Satel Abax 2 or Ajax) use encrypted, two-way radio transmission across multiple bands simultaneously. In the event of a signal jamming attempt, the system immediately changes frequency and alerts the owner of sabotage.

Is a DIY alarm kit a good solution?

Yes, especially in the case of wireless systems. Manufacturers like Ajax design their devices using Smart-Placement – detectors are added to the control panel using QR codes in a mobile app, and installation is limited to screwing brackets in place. For simple wired systems (e.g., Satel Perfecta), installation can also be done independently with the help of our technical advisors.

What features does a modern home alarm system have?

Modern alarm systems go far beyond burglary detection. They protect the home from water damage (flood detectors), detect early stages of fire (smoke and heat detectors), and carbon monoxide leaks. They can also shut off the main water valve in case of a failure and control lighting, roller shutters, and heating.

How does a phone-controlled alarm work?

A control panel equipped with an IP or IP/GSM module connects to the manufacturer's dedicated, secure cloud. Via a free smartphone app (Android/iOS), the user can arm or disarm the system (the whole house or selected zones) from anywhere in the world, view event history, and receive instant push notifications about alarms.

How do pet-immune motion detectors (PET function) work?

Pet-immune detectors ignore the presence of dogs or cats (usually up to 15-20 kg). This is achieved through a specially designed Fresnel lens that creates a "dead zone" near the floor, or advanced digital signal processing that analyzes the size and thermal characteristics of the moving object. Dual technology detectors (PIR+MW) are recommended for homes with pets.

Why is an alarm with GSM notification and a SIM card a necessity?

GSM notification is a crucial backup channel for internet communication (Wi-Fi/LAN). In the event of a home router failure or intentional power cutoff by a burglar, the alarm control panel automatically switches to the GSM cellular network. This enables uninterrupted SMS alerts, voice calls (VOICE), and effective signal transmission to a security agency.

⚡ Gate Automation and Drives

What sliding gate drive to choose for up to 500kg?

When choosing a drive, always keep a 30-50% safety margin relative to the gate weight so that the actuator easily handles resistance in winter conditions (snow, frost). For a sliding gate weighing up to 500kg, proven, legendary drives based on metal gears are the ideal choice, characterized by reliability and easy movement parameter programming.

What swing gate drive to choose – narrow or wide posts?

This is a key installation parameter. For narrow posts (metal or clinker with a hinge mounting depth of up to 10-15 cm), standard linear screw actuators are used. For very wide posts (e.g., made of split-face concrete blocks where the distance from the hinge to the edge of the post is over 20 cm), a regular actuator will jam against the edge. In this case, articulated arm drives are necessary.

Nice, Came or BFT gate automation kit – what to choose?

All three brands represent the highest European quality and guarantee full availability of spare parts for years. **Came** is famous for incredibly durable mechanical designs and service simplicity. **Nice** offers modern design, advanced control panels, and a very popular line of home drives. **BFT** stands out with advanced 24V power technology featuring intelligent torque management (D-Track system).

Universal gate remote control – how does programming work?

Universal self-copying remotes work smoothly with fixed codes (usually 433.92 MHz). However, branded drives use secure rolling codes. To program a new remote, you usually need to trigger the pairing procedure directly on the radio receiver inside the drive control panel or use a previously programmed remote via radio (near the gate), following the procedure described in the manufacturer's manual.

Gate photocells – connection and operating principle?

Photocells consist of a transmitter (TX) and receiver (RX) creating an invisible infrared barrier across the driveway opening. The receiver is connected to the control panel using a power cable and an NC (Normally Closed) line to the safety input (PHOTO/STOP). Breaking the infrared beam during gate closing results in the immediate stop of the wings and their safe reversal, preventing impact on a vehicle or person.

What cable should be laid in the ground for a gate drive?

To supply main power to the drive control panel (230V), use a three-core, dedicated underground cable in a thick black PVC sheath resistant to moisture and UV, such as **YKY 3x1.5 mm²** or **YKY 3x2.5 mm²** (for greater distances from the switchboard). For connecting accessories (photocells, warning lamp, wall buttons), gel-filled outdoor underground twisted-pair cable **U/UTP cat. 5E** or low-voltage signal cable **YTDY** is ideal.
