CCTV, Door Access & Security Systems in Singapore
Surveillance Zone has been installing and servicing security systems in Singapore since 2003. We are an SPF-Registered Security Service Provider with over 200 five-star Google reviews, covering CCTV installation, maintenance and upgrade, door access control and short-term rental. Every job is done by our own certified in-house installers, using genuine Hikvision and Dahua equipment.
CCTV Installation Singapore

Our flagship service. We install HD, 4K and ColorVu full-colour night vision systems for HDB flats, condominiums, landed homes, offices, shops and industrial premises. Every job starts with a free on-site survey, so camera count and positions come from what your property needs, not a package picked over the phone.
Placement matters more than megapixels. A 4K camera at the wrong angle gives a clear picture of the top of someone's head. Night performance is the other thing cheap systems get wrong: standard infrared switches to black and white after dark, showing that something happened but not what colour shirt or car.
- Professional site survey and camera placement
- HD, 4K and ColorVu full-colour night vision
- Neat, concealed cabling
- Mobile and remote viewing setup
- HDB and condo compliant installation
- Genuine, warrantied Hikvision and Dahua
CCTV Maintenance Singapore, Any Brand

A camera that is powered on is not the same as a camera that is recording. Most CCTV failures are silent, and the owner finds out on the day the footage is actually needed.
We service, repair and upgrade existing systems of any brand, whoever installed them. Hard drives are consumable parts and a recorder writes continuously, so storage failure is a question of when. Dirty domes bloom infrared glare back into the lens at night, and remote viewing breaks when a router changes and nobody reconnects the recorder.
- System health checks and cleaning
- Fault diagnosis and repair
- Storage and NVR upgrades
- Camera resolution upgrades
- Firmware and remote-access fixes
Door Access System Singapore

CCTV tells you what happened. Door access control decides who gets in at all. We install and configure access systems for offices, condominiums and restricted areas, from proximity card and PIN readers to facial-recognition terminals.
Choosing a credential is a trade-off. Cards are cheap to issue but can be lent or lost. PIN codes cost nothing but get passed around. Fingerprint readers tie access to the person. Facial recognition is hands-free and fast, which suits busy lobbies. The log is what pays for itself: a record of who entered and when settles disputes about after-hours entry.
- Proximity card and PIN readers
- Facial-recognition access (Dahua)
- Biometric and fingerprint options
- Integration with existing gates
- Visitor and staff access logs
CCTV Rental Singapore

Not every site needs a permanent installation. For events, renovations, construction sites and temporary premises, buying a system that gets pulled out in six weeks makes no sense. Our rental is fully managed with 4, 8 and 16-camera setups: we install it and we come back and remove it, with live remote monitoring included.
- Flexible 4, 8 and 16-camera setups
- Fully managed, we install and remove
- Live remote monitoring
- No long-term commitment
How to Choose Camera Type and Placement
Camera shape is a functional choice. Domes sit flush, resist knocks and hide which way they aim, which suits corridors. Bullets are visible, useful when you want the camera itself to deter, and suit long fixed views along a driveway.
Resolution is only half the picture. What makes footage usable for identification is how many pixels land on a face, which depends on resolution, field of view and distance together. A wide camera watching a whole car park shows movement, not identities.
- Cover entry points first: main door, gate, back door, car park
- Pair a wide overview camera with a tight camera at the choke point
- Mount out of reach but low enough to capture faces
- Aim across an entrance, not into direct backlight
- Point cameras at your own property, not a neighbour's
HDB CCTV Installation, Condos and Compliance
Where you live changes what you are allowed to do, so check before the drilling starts. Inside your own HDB flat is your business. A camera facing the common corridor is different, because the corridor is common property. You generally need permission from HDB and your Town Council, and conditions differ between towns. For condos, anything outside your unit normally needs MCST approval.
Recording brings data obligations too. Footage of identifiable people is personal data, so PDPA obligations apply to how you collect, use, secure and retain it. Security work is also a regulated trade here, and installers of certain systems must be licensed. We are an SPF-Registered Security Service Provider using our own certified in-house installers.
What the Installation Process Looks Like
It starts with a free on-site survey, no obligation. We walk the property, look at entry points, sightlines, lighting and where the recorder and power can sit, and confirm cable routes. That survey turns an indicative package price into a firm quotation, because cabling distance and mounting conditions are the variables.
On installation day the team mounts the cameras, conceals the cabling, configures the recorder and storage, then aims each camera on a live view rather than by eye from the ladder. Installation is usually completed within the week.
- Free on-site survey, no obligation
- Fixed quotation after the survey
- Mounting, concealed cabling, recorder and storage setup
- Phone and remote viewing setup, plus handover
- Usually completed within the week
CCTV Installation Cost: What Moves the Price
Our packages are before GST and include supply, installation, setup and 1TB of surveillance storage. Hikvision starts from $550 for one camera, $750 for two, $850 for three and $950 for four. Dahua starts from $650, $900, $1,100 and $1,300 for the same counts.
Those are from-prices for standard installations, and what changes them is mostly cabling and access. Four cameras in a compact flat with the recorder close by is a different day's work from four across a landed house with long runs and external trunking. Holding more days of footage needs more storage, since camera count and resolution decide how fast a drive fills.
