Top 7 Features to Look for When Choosing Security Cameras

Finding the ideal security camera for your specific needs in Malaysia can feel like finding a needle in a haystack. Every spec sheet is buried under tech terms that sound impressive, but don’t always mean protection. 

After all, all that glitters is not gold.

Not every feature you see on the box actually makes your home or shop safer. Some features are absolute deal-breakers, while others are just nice-to-have add-ons that quietly inflate the cost without improving security.

A camera that performs well overseas may struggle locally if it isn’t built for Malaysia’s tropical climate. That’s why knowing how to choose a security camera is essential knowledge.

This guide breaks down the 7 must-have security camera features every Malaysian should look for before purchasing to avoid costly mistakes.

1. Video Resolution: Captures Critical Details

When it comes to security cameras, resolution is everything. The most critical factor in a camera is its ability to capture clear evidence. It is only helpful if you can clearly identify faces, read vehicle number plates, or see exactly what happened during an incident.

Camera resolution is measured in pixels (the tiny dots that make up an image). The more pixels a camera has, the more detail it can capture and preserve, especially when you digitally zoom in on recorded footage. 

• 1080P (Full HD)
  1080p (1920 x 1080 pixels) is considered the minimum recommended resolution for security cameras. It provides sufficient clarity for general monitoring of small areas, such as a front door or a narrow hallway.
  
  It is ideal for objects within close range, typically 5 to 10 metres. It’s also more cost-effective for beginner-friendly setups, requiring less storage space and lower internet bandwidth.
  
  Many SriHome WiFi cameras start at 1080p, making them ideal for homeowners and small shop owners who want reliable, clear footage without a complicated setup.
  
  
• 2K (4MP)
  If you are monitoring a larger area, such as a shop floor or a wide driveway, you need higher resolution to maintain detail across the entire scene.
  
  2K cameras (2688 x 1520 pixels) offer extra pixels that allow for a broader field view without sacrificing clarity when zooming in on recordings. Always keep in mind that higher resolution also means increased storage and bandwidth usage.
  
  
• 4K (8MP)
  Ultra-high resolution cameras like 4K (3840 × 2160 pixels) deliver roughly four times the pixels of 1080P, making them suitable for very large spaces where long-distance clarity is required.
  
  However, this comes at a cost: higher bandwidth consumption, larger storage requirements, and a higher upfront price.
   

HD vs 2K vs 4K: Which One Is Right for You?

Note: For most users, 1080p is the sweet spot. Upgrade to 2K or 4K only if you’re covering wide areas or need advanced zoom capability.

2. Night Vision: 24/7 Protection in Complete Darkness

While camera resolution matters, once the sun goes down, your CCTV footage depends entirely on its night-vision technology. Data indicate that 77.6% of reported home break-ins or thefts in Malaysia take place at night. This means night vision is non-negotiable for effective surveillance.

Infrared (IR) night vision

Most of the security cameras rely on infrared (IR) for night vision when there’s little to no visible light. IR LEDs emit invisible infrared light that reflects off objects, allowing the camera to capture footage even in complete darkness. 

This produces the familiar black-and-white video commonly seen in night recordings. For most homes and small businesses, an IR range of 15 to 30 metres is sufficient to cover areas such as front yards, driveways, shop entrances, and corridors.

Pros

• Works in complete darkness
• Reliable and power-efficient
• Ideal for close-range monitoring

Cons

• Cannot identify colours (clothing, vehicles, bags) if needed, critical descriptive information

Colour night vision

Modern surveillance has largely shifted to Full-Colour Night Vision, which captures more detailed, identifiable footage after dark. This is typically achieved using one of two technologies:

• Starlight Sensors: These cameras use ambient lighting, such as a distant streetlamp or the moonlight, to capture full-colour footage at night.
• LED Floodlights: Some use built-in white LEDs to illuminate the scene.

Pros

• Captures clothing, vehicle, and object colours
• Better for identification and evidence
• Ideal for entrances and outdoor areas

Cons

• Requires some light source to function
• LED lights may be noticeable at night

It is recommended to purchase CCTV with hybrid night-vision options. You can easily switch between black-and-white infrared mode and full-colour night vision, depending on your surroundings and lighting conditions. This ensures your security system performs just as reliably at 3 AM as it does at 3 PM.

3. Motion Detection and Smart Alerts: Reduce False Alarms

There’s nothing more frustrating than receiving a motion alert every time a bird flies past, a vehicle drives by, or even your neighbour’s cat wanders across the lawn. This is why smart detection is an essential upgrade that turns your camera into a truly useful surveillance tool.

Smart motion detection transforms a security camera from a passive recorder into an active security system. Instead of pushing constant notifications, the camera alerts you only when something important happens.

Smart Detection Features You Need

AI Humanoid Detection

While basic motion detection relies primarily on pixel changes in the video feed, AI-powered motion detection recognises the shape and movement of a person, filtering out non-human motion such as pets, passing cars, rain, or moving shadows.

Auto Motion Tracking

For cameras with Pan-Tilt-Zoom (PTZ) functionality, auto motion tracking enables the camera to pan and tilt automatically when a person is detected. This keeps the subject in frame as they move and ensures continuous recording if an intruder walks across your property. 

Customisable Motion Zones

If your cameras are overlooking a busy street or a neighbour's area, you can create custom motion zones by drawing specific detection areas and excluding unnecessary ones. This helps prevent constant, irrelevant notifications.

This feature is available on SriHome CCTV cameras through SriHome’s CCTV monitoring mobile app, ensuring you’re alerted only to meaningful activity. You can also enable privacy masking, which hides sensitive areas from the camera’s view.

With the Mobile app, you can easily fine-tune motion zones, detection sensitivity, and alert schedules, all directly from your smartphone. 

4. Storage Options: Never Lose Important Footage

Even if you capture the perfect incident on video, it’s useless if you can’t easily access or play it back. The clearest footage means nothing if the recording is missing when you need it most.

That’s why choosing the right storage option is a critical part of any security camera setup. Most security cameras today offer two main types of storage: cloud storage and local storage.

Cloud Storage

Cloud storage uploads recorded footage to remote servers, allowing you to access your recordings anytime, anywhere through a mobile app. Footage is transmitted and stored using an internet connection.

Pros

• Easy remote access
• Footage remains safe even if the camera is stolen
• No physical storage to manage

Cons

• Usually requires a monthly or yearly subscription
• Relies on a stable internet connection

Local Storage

Local storage saves recordings directly on the device, either via a microSD card inside the camera or through a Network Video Recorder (NVR) with a hard disk installed.

An NVR system allows CCTV cameras to record video and audio digitally and store the footage on a central storage device, such as a hard drive inside the NVR unit. This system works with cameras that transmit digital video over a local network. 

Pros

• One-time cost with no monthly subscription fees
• Continues recording even if the internet connection goes down
• Full control and ownership of your footage

Cons

• Storage capacity is limited by the memory card or hard disk size
• Footage may be lost if the storage device is damaged or stolen

Choose the Right Storage Setup

Tip 1: Consider a Hybrid Storage Setup

Hybrid storage combines local recording with optional cloud backup, giving you both reliability and flexibility. Local storage handles continuous or motion-triggered recording, while cloud storage acts as a backup for important clips.

This setup is especially useful in Malaysia, where power interruptions and unstable internet connections are not uncommon, particularly during the heavy rain period.

Note: If you prefer zero monthly fees, a local storage-only setup (microSD or NVR) is still a reliable and cost-effective option.

Tip 2: Calculate Your Footage Needs Before Buying

For a standard 1080P camera using H.265 compression, a 128GB MicroSD card can typically hold 8 to 12 days of key event footage. If you plan to use 24/7 recording, multiple cameras, or higher resolutions (2K or 4K), you will need significantly more storage capacity.

For centralised, high-volume storage, the SriHome NVR Wireless System offers professional capacity, supporting a Hard Disk Drive (HDD) up to 16TB on specific models. Always choose an option that matches your resolution, recording mode, and usage needs.

5. Two-Way Audio: Communicate Through Your Camera

With modern advancements, two-way audio transforms your camera into an interactive security tool, giving you a real remote presence even when you’re not there.

This two-way voice intercom feature allows you to hear and speak through your camera using your smartphone, turning your CCTV system from a passive tool into an active line of communication.

The feature includes a built-in microphone and speaker, which lets you:

• Speak to delivery drivers
  You can communicate with a PosLaju or Grab delivery rider when you’re stuck in traffic, asking them to leave the parcel behind a specific planter.
  
• Warn suspicious trespassers through the camera setup
  In many cases, a clear human voice warning is enough to stop suspicious behaviour before it escalates into a real incident.
  
  
• Check on family members, staff, or pets
  Use indoor cameras as a convenient voice intercom to check in at home or at work.
  
  
• Communicate without being on-site
  You can use the camera to remotely address employees or customers, clarify instructions, or answer simple questions without being physically present.
  

6. Weather Resistance: Built for Malaysia's Climate

Malaysia’s climate makes surveillance especially challenging, which is why generic CCTV camera advice often falls short for local buyers. Typically, the high humidity, sudden temperature changes, and heavy monsoon rain can be extremely harsh on outdoor electronics.

It is highly crucial to choose cameras with well-sealed housings that perform consistently in tropical conditions. This is why the Ingress Protection (IP) rating is important. 

An IP rating indicates how well a device is protected against solid particles like dust and liquids such as water. For reliable outdoor use in Malaysia, always go for a minimum IP65 or IP66 rating:

• First digit (6): Complete protection against dust, preventing dirt and grime from affecting internal components and lens clarity
  
  
• Second digit (5-6): Protection against powerful water jets and heavy rain, making it suitable even during intense monsoon seasons

SriHome outdoor cameras are IP65/IP66-rated and feature a weather-resistant housing that offers stable performance even during prolonged rain or high-humidity days.

7. Connectivity and Smart Home Integration

The final link in the security chain is connectivity. Poor connectivity can lead to delayed alerts, dropped footage, or laggy live viewing, defeating the purpose of having a security system in the first place.

Most modern home and small-business security cameras use Wi-Fi connectivity, making them easy to install and flexible in placement. For larger or more demanding setups, wired systems such as Power-over-Ethernet (PoE) offer higher stability and reliability.

Wired (PoE) Cameras

PoE cameras use a single Ethernet cable to deliver both power and data. It offers a stable connection with minimal interference and is not affected by Wi-Fi signal strength, making it ideal for long-term, professional surveillance setups.

Best for:

• Warehouses and factories
• Offices with multiple cameras
• Users who need 24/7, uninterrupted recording

Wireless (Wi-Fi) Cameras

Wi-Fi cameras are popular for homes and small businesses due to their easy installation and flexibility. Their performance depends largely on Wi-Fi band support.

• 2.4GHz WiFi (Long Range)

This is the standard band supported by all SriHome cameras. The 2.4GHz signal penetrates walls and floors much better than 5GHz, ensuring outdoor cameras maintain a strong and stable connection even when placed far from the router.

• 5GHz WiFi (High Speed)

This band offers much faster data speeds ideal for streaming high-resolution footage like 2K/4K CCTV with minimal lag. 

Premium SriHome cameras often offer dual-band (2.4 GHz & 5 GHz) support, allowing you to choose the 5 GHz band for performance near the router (commonly for indoor cameras) or switch to 2.4 GHz for better range.

Note: Choose 2.4 GHz if distance and signal penetration are your main concerns, and 5 GHz if speed and smoother live viewing matter most.
